Presentation

372: Which of the following attacks could be the most successful when the security technology is properly implemented and configured? A. Logical attacks B. Physical attacks C. Social Engineering attacks D. Trojan Horse attacks

C Explanation: CISSP Actualtests.com - The Power of Knowing Social Engineering attacks - In computer security systems, this type of attack is usually the most successful, especially when the security technology is properly implemented and configured. Usually, these attacks rely on the faults in human beings. An example of a social engineering attack has a hacker impersonating a network service technician. The serviceman approaches a low-level employee and requests their password for network servicing purposes. With smartcards, this type of attack is a bit more difficult. Most people would not trust an impersonator wishing to have their smartcard and PIN for service purposes.

683: Sensor is: A. Logical, Physical B. Corrective, Logical C. Detective, Physical D. Corrective, Physical CISSP Actualtests.com - The Power of Knowing

C Explanation: Detective Physical Controls would use the following: motion detectors, closed circuit TV, sensors, and alarms.

387: Under MAC, a clearance is a: A. Sensitivity B. Subject C. Privilege D. Object

C Explanation: It is important to note that mandatory controls are prohibitive (i.e., all that is not expressly permitted is forbidden), not permissive. Only within that context do discretionary controls operate, prohibiting still more access with the same exclusionary principle. In this type of control system decisions are based on privilege CISSP Actualtests.com - The Power of Knowing (clearance) of subject (user) and sensitivity (classification) of object (file). It requires labeling.

403: CISSP Actualtests.com - The Power of Knowing Which of the following will you consider as a "role" under a role based access control system? A. Bank rules B. Bank computer C. Bank teller D. Bank network

C Explanation: With role-based access control, access rights are grouped by role name, and the use of resources is restricted to individuals authorized to assume the associated role. For example, within a hospital system the role of doctor can include operations to perform diagnosis, prescribe medication, and order laboratory tests; and the role of researcher can be limited to gathering anonymous clinical information for studies.

1232: The baseline sets certain thresholds for specific errors or mistakes allowed and the amount of these occurrences that can take place before it is considered suspicious? A. Checkpoint level B. Ceiling level C. Clipping level D. Threshold level

C Explanation: According to CISSP documentation, this is the proper term, The Clipping level is used to determine suspicious occurrences that are a production of errors or mistakes. Checkpoint level is not a related term. Ceiling level is not related to baselines. Threshold level is attractive, but is not the correct term. Take a look at your CISSP documentation.

1298: Which Orange Book evaluation level is described as "Structured Protection"? A. A1 B. B3 C. B2 D. B1

C Explanation: Class B2 corresponds to Structured Protection. Division B - Mandatory Protection Mandatory access is enforced by the use of security labels. The architecture is based on the Bell-LaPadula security model and evidence of the reference monitor enforcement must be available. B1: Labeled Security Each data object must contain a classification label and each subject must have a clearance label. When a subject attempts to access an object, the system must compare the subject and the object's security labels to ensure the requested actions are acceptable. Data leaving the system must also contain an accurate security label. The security policy is based on an informal statement and the design specifications are reviewed and verified. It is intended for environments that handle classified data. B2: Structured Protection The security policy is clearly defined and documented and the system design and implementation is subjected to more thorough review and testing procedures. This class requires more stringent authentication mechanisms and well-defined interfaces between layers. Subject and devices require labels, and the system must not allow covert channels. A trusted path for logon and authentication processes must be in place, which means there are no trapdoors. There is a separation of operator and administration functions within the system to provide more trusted and protected operational functionality. Distinct address spaces must be provided to isolated processes, and a covert channel analysis is conducted. This class adds assurance by adding requirements to the design of the system. The environment that would require B2 systems could process sensitive data that requires a higher degree of security. This environment would require systems that are relatively resistant to penetration and compromise. B3 Security Domains In this class, more granularity is provided in each protects mechanism and the programming code that is not necessary to support the security is excluded. The design and implementation should not provide too much complexity because as the complexity of a system CISSP Actualtests.com - The Power of Knowing increases, the ability of the individuals who need to test, maintain, and configure it reduces; thus, the overall security can be threatened. The reference monitor components must be small enough to test properly and be tamperproof. The security administrator role is clearly defined and the system must be able to recover from failures without its security level being compromised. When the system starts up and loads its operating system and components, it must be done in an initial secure state to ensure any weakness of the system cannon be taken advantage of in this slice of time. An environment that requires B3 systems is a highly secured environment that processes very sensitive information. It requires systems that are highly resistant to penetration. Note: In class (B2) systems, the TCB is based on a clearly defined and documented formal security policy model that requires the discretionary and mandatory access control enforcement found in class (B1) systems be extended to all subjects and objects in the ADP system. In addition, covert channels are addressed. The TCB must be carefully structured into protection-critical and non-protection-critical elements. Class B corresponds to "Structured Protection" inside the Orange Book.

1345: When an organization takes reasonable measures to ensure that it took precautions to protect its network and resources is called: A. Reasonable Action B. Security Mandate C. Due Care D. Prudent Countermeasures

C Explanation: Due care are the steps taken to show it has taken responsibility for its actions.

1303: Which of the following department managers would be best suited to oversee the development of an information security policy? A. Information systems B. Human resources C. Business operations D. Security administration

C Explanation: He is the most appropriate manager, this is because he know the inns and outs of the business processes inside the company. Remember that he manages the business operations, and are those operations the ones that make the company live and generate the revenue. He knows who should access what and when. Security administrators develop the policy with the information provided by persons like the Business operations manager. Human Resources is not appropriate in this case, and the Information systems manager know about the technology, but not the business needs of the company.

1308: What is called the number of columns in a table? A. Schema B. Relation C. Degree D. Cardinality

C Explanation: In database terminology, is the same to say that the number of Degrees is "X" and that the number of columns is "X" inside a Table. This question is just trying to test our knowledge of rare, difficult to fin terminology. You can check this in the knowledgebase of Oracle. When we talk about degrees, we are just talking about columns. The schema is the structure of the database, and the relations are the way each table relates to others.

1173: Which type of control would password management classify as? A. Compensating control B. Detective control C. Preventive control D. Technical control

C Explanation: Preventive technical controls are used to prevent unauthorized personnel or programs from gaining remote access to computing resources. Examples of these controls include: Access control software. Antivirus software. Library control systems. Password and Password management Smart cards. Encryption. Dial-up access control and callback sytems About Passwords: Passwords are used to verify that the user of an ID is the owner of the ID. The ID-password combination is unique to each user and therefore provides a means of holding users accountable for their activity on the system. Fixed passwords that are used for a defined period of time are often easy for hackers to compromise; therefore, great care must be exercised to ensure that these passwords do not CISSP Actualtests.com - The Power of Knowing appear in any dictionary. Fixed passwords are often used to control access to specific data bases. In this use, however, all persons who have authorized access to the data base use the same password; therefore, no accountability can be achieved. Currently, dynamic or one-time passwords, which are different for each log-on, are preferred over fixed passwords. Dynamic passwords are created by a token that is programmed to generate passwords randomly. The management of those passwords is part of Preventive control.

1247: How fast is private key cryptography compared to public key cryptography? A. 10 to 100 times faster. B. 100 to 1000 times faster. C. 1000 to 10000 times faster. D. 10000 to 20000 times faster.

C Explanation: Since Private Key encryption (Symmetric) only has one key for encrypt-decrypt, you need to use an alternative way to pass the shared secret in a secure manner, in our days, it's usually done by telephone or some secure methods that not involve the channel you are trying to secure. Also, since you need one different key to encrypt-decrypt every connection, the number of keys gets huge in a little time, for example, if we have 10 users trying to communicate between themselves, we have 100 different encryption keys to manage. There is an advantage for Private key encryption, the encryption is very fast, about 1000 / 10000 times faster than asymmetric encryption.

210: Which security model allows the data custodian to grant access privileges to other users? A. Mandatory B. Bell-LaPadula C. Discretionary D. Clark-Wilson

C "An application-level gateway firewall is also called a proxy firewall. A proxy is a mechanism that copies packets from one network into another; the copy process also changes the sources and destination address to protect the identity of the internal or private network. An application-level gateway firewall filters traffic based on the Internet service (i.e., application) used to transmit or receive the data." - Shon Harris All-in-one CISSP Certification Guide pg 92

167: What is the main concern of the Bell-LaPadula security model? A.) Accountability B.) Integrity C.) Confidentiality D.) Availability

C "An important thing to note is that the Bell-LaPadula model was developed to make sure secrets stay secret; thus, it provides and addresses confidentially only.

1079: After law enforcement is informed of a computer crime, the organization's investigators constraints are A. removed. B. reduced. C. increased. D. unchanged. CISSP Actualtests.com - The Power of Knowing

C "On the other hand, there are also two major factors that may cause a company to shy away from calling in the authorities. First, the investigation will more than likely become public and may embarrass the company. Second, law enforcement authorities are bound to conduct an investigation that complies with the Fourth Amendment and other legal requirements that may not apply to a private investigation." Pg. 529 Tittel: CISSP Study Guide

56: Which one of the following is a characteristic of a penetration testing project? A. The project is open-ended until all known vulnerabilities are identified. B. The project schedule is plotted to produce a critical path. C. The project tasks are to break into a targeted system. D. The project plan is reviewed with the target audience.

910: By examining the "state" and "context" of the incoming data packets, it helps to track the protocols that are considered "connectionless", such as UDP-based applications and Remote Procedure Calls (RPC). This type of firewall system is used in: A.) first generation firewall systems B.) second generation firewall systems C.) third generation firewall systems D.) fourth generation firewall systems

C "Stateful Inspection Characteristics The firewall maintains a state table that tracks each and every communication channel. Frames are analyzed at all communication layers. It provides a high degree of security and does not introduce the performance hit that proxy firewalls introduce. It is scaleable and transparent to users It provides data tracking for tracking connectionless protocols such as UDP and ICMP The stat and context of the data within the packets are stored and updated continuously. It is considered a third-generation firewall." Pg. 375 Shon Harris: All-in-One CISSP Certification Not A: "Packet filtering is the first generation firewall-that is, it was the first type that was created and used, and other types were developed fall into different generations." Pg 373 Shon Harris: All-in-One CISSP Certification

287: How are memory cards and smart cards different? A.) Memory cards normally hold more memory than smart cards B.) Smart cards provide a two-factor authentication whereas memory cards don't C.) Memory cards have no processing power D.) Only smart cards can be used for ATM cards

C "The main difference between memory cards and smart cards is the processing power. A memory card holds information, but does not process information. A smart card has the necessary hardware and logic to actually process information." Pg 121 Shon Harris CISSP All-In-One Exam Guide

760: The repeated use of the algorithm to encipher a message consisting of many blocks is called CISSP Actualtests.com - The Power of Knowing A. Cipher feedback B. Elliptical curve C. Cipher block chaining D. Triple DES

C "There are two main types of symmetric algorithms: stream and block ciphers. Like their names sound, block ciphers work on blocks of plaintext and ciphertext, whereas stream ciphers work on streams of plaintext and ciphertext, on bit or byte at a time. Pg 521. Shon Harris CISSP All-In-One Certification Exam Guide Cipher Block Chaining (CBC) operates with plaintext blocks of 64 bits. ....Note that in this mode, errors propogate." Pg 149 Krutz: The CISSP Prep Guide

Reverse engineering, content modification, factoring attacks, and submission notification. D. Masquerading, content modification, sequence manipulation, and submission notification.

C Unique session values: "IPSec: ....Each device will have one security association (SA) for each session that it uses. The SA is critical to the IPSec architecture and is a record of the configuration the device needs to support an IPSec connection. Pg 575 Shon Harris All-In-One CISSP Certification Exam Guide. Message authentication and content modification: "Hashed Message Authentication Code (HMAC): An HMAC is a hashed alogrithim that uses a key to generate a Message Authentication Code (MAC). A MAC is a type of check sum that is a function of the information in the message. The MAC is generated before the message is sent, appended to the message, and then both are transmitted. At the receiving end, a MAC is generated from the message alone CISSP Actualtests.com - The Power of Knowing using the same algorithm as used by the sender and this MAC is compared to the MAC sent with the message. If they are not identical, the message was modified en route. Hashing algorithms can be used to generate the MAC and hash algorithms using keys provide stronger protection than ordinary MAC generation. Frequency analysis: Message authentication and session values do not protect against Frequency Analysis so A and B are eliminated. "Simple substitution and transposition ciphers are vulnerable to attacks that perform frequency analysis. In every language, there are words and patters that are used more often than others. For instance, in the English language, the words "the.' "and," "that," and "is" are very frequent patters of letters used in messages and conversation. The beginning of messages usually starts "Hello" or "Dear" and ends with "Sincerely" or "Goodbye." These patterns help attackers figure out the transformation between plaintext to ciphertext, which enables them to figure out the key that was used to perform the transformation. It is important for cryptosystems to no reveal these patterns." Pg. 507 Shon Harris All-In-One CISSP Certification Exam Guide Ciphertext-Only Attack: Message authentication and session values do not protect against Ciphertext so A and B are again eliminated. "Ciphertext-Only Attack: In this type of an attack, an attacker has the ciphertext of several messages. Each of the messages has been encrypted using the same encryption algorithm. The attacker's goal is to discover the plaintext of the messages by figuring out the key used in the encryption process. Once the attacker figures out the key, she can now decrypt all other messages encrypted with the same key." Pg 577 Shon Harris All-In-One CISSP Certification Exam Guide. Birthday attack: "....refer to an attack against the hash function known as the birthday attack." Pg 162 Krutz: The CISSP Prep Guide. MAC utilizes a hashing function and is therefore susceptible to birthday attack. Masguerading Attacks: Session values (IPSec) does protect against session hijacking but not spoofing so C is eliminated. "Masguerading Attacks: ....we'll look at two common masquerading attacks - IP Spoofing and session hijacking." Pg 275 Tittel: CISSP Study Guide. Session hijacking: "If session hijacking is a concern on a network, the administrator can implement a protocol that requires mutual authentication between users like IPSec. Because the attacker will not have the necessary credentials to authenticate to a user, she cannot act as an imposter and hijack sessions." Pg 834 Shon Harris All-In-One CISSP Certification Exam Guide Reverse engineering: Message authentication protects against reverse engineering. Reverse engineering: "The hash function is considered one-way because the original file cannot be created from the message digest." Pg. 160 Krutz: The CISSP Prep Guide Content modification: Message authentication protects against content modification. Factoring attacks: Message authentication protects against factoring attacks.

D CISSP Actualtests.com - The Power of Knowing Explanation: Memory Only Card - This type of card is the most common card. It has a magnetic stripe on the back. These cards can offer two-factor authentication, the card itself (something you have) and the PIN (something you know). Everyone is familiar with the use of an ATM (Automated Teller Machine) card. These memory cards are very easy to counterfeit. There was a case in Montreal where a storeowner would swipe the card through for the transaction; he hould then swipe it through a card reader to get a copy while a small hidden camera was registering the PIN as the user was punching it on the pad. This scheme was quickly identified as the victims had one point in common; they all visited the same store.

580: The auditing method that assesses the extent of the system testing, and identifies specific program logic that has not been tested is called A. Decision process analysis B. Mapping C. Parallel simulation D. Test data method

D "Testing of software modules or unit testing should be addressed when the modules are being designed. Personnel separate from the programmers should conduct this testing. The test data is part of the specifications. Testing should not only check the modules using normal and valid input data, but it should also check for incorrect types, out-of-range values, and other bounds and/or conditions. Live or actual field data is not recommended for use in the testing procedures because both data types might not cover out-of-range situations and the correct outputs of the test are unknown. Special test suites of data that exercise all paths of the software to the fullest extent possible and whose corrected resulting outputs are known beforehand should be used."

415: Which expert system operating mode allows determining if a given hypothesis is valid? CISSP Actualtests.com - The Power of Knowing A.) Vertical chaining B.) Lateral chaining C.) Forward chaining D.) Backward chaining

D "The expert system operates in either a forward-chaining or backward-chaining mode. In a forward-chaining mode, the expert system acquires information and comes to a conclusion based on that information. Forward-chaining is the reasoning approach that can be used when there is a small number of solutions relative to the number of inputs. In a backward-chaining mode, the expert system backtracks to determine if a given hypothesis is valid. Backward-chaining is generally used when there are a large number of possible solutions relative to the number of inputs. Another type of expert system is the blackboard. A blackboard is an expert system-reasoning methodology in which a solution is generated by the use of a virtual "blackboard," wherein information or portential solutions are placed on the blackboard by the plurality of individuals or expert knowledge sources. As more information is placed on the blackboard in an iterative process, a solution is generated." Pg 354 Krutz: The CISSP Prep Guide: Gold Edition

203: What security model implies a central authority that determines what subjects can have access to what objects? A.) Centralized access control B.) Discretionary access control C.) Mandatory access control D.) Non-discretionary access control

150: Which TCSEC (Orange Book) level requires the system to clearly identify functions of security administrator to perform security-related functions? A.) C2 B.) B1 C.) B2 D.) B3

D B1: Labeled Security Each data object must contain a classification label and each subject must have a clearance label. When a subject attempts to access an object, the system must compare the subject and object's security labels to ensure the requested actions are acceptable. Data leaving the system must also contain an accurate security label. The security policy is based on an informal statement and the design specifications are reviewed and verified. It is intended for environments that require systems to handle classified data. B2: Structured Protection The security policy is clearly defined and documented, and the system design and implementation are subjected to more thorough review and testing procedures. This class requires more stringent authentication mechanisms and well-defined interfaces among layers. Subjects and devices require labels, and the system must not allow covert channels. A trusted path for logon and authentication processes must be in place, which means there are no trapdoors. A trusted path means that the subject is communicating directly with the application or operating system. There is no way to circumvent or compromise this communication channel. There is a separation of operator and administration functions within the system to provide more trusted and protected operational functionality. Distinct address spaces must be provided to isolate processes, and a covert channel analysis is conducted. This class adds assurance by adding requirements to the design of the system. The environment that would require B2 systems could process sensitive data that require a higher degree of security. This environment would require systems that are relatively resistant to penetration and compromise. (A trusted path means that the user can be sure that he is talking to a genuine copy of the operating system.) B3: Security Domains In this class, more granularity is provided in each protection mechanism, and the programming code that is not necessary to support the security policy is exclude. The design and implementation should not provide too much complexity because as the complexity of a system increases, the ability of the individual who need to test, maintain, and configure it reduces; thus, the overall security can be threatened. The reference monitor components must be small enough to test properly and be tamperproof. The security administrator role is clearly defined, and the CISSP Actualtests.com - The Power of Knowing system must be able to recover from failures without it security level being compromised. When the system starts up and loads it operating system and components, it must be done in an initial secure state to ensure that any weakness of the system cannot be taken advantage of in this slice of time.

345: CISSP Actualtests.com - The Power of Knowing Monitoring electromagnetic pulse emanations from PCs and CRTs provides a hacker with that significant advantage? A. Defeat the TEMPEST safeguard B. Bypass the system security application. C. Gain system information without trespassing D. Undetectable active monitoring.

D Tempest equipment is implemented to prevent intruders from picking up information through the airwaves with listening devices. - Shon Harris All-in-one CISSP Certification Guide pg 192. In Harris's other book CISSP PASSPORT, she talks about tempest in terms of spy movies and how a van outside is listening or monitoring to the activities of someone. This lends credence to the answer of C (trespassing) but I think D is more correct. In that all the listener must do is listen to the RF. Use your best judgment based on experience and knowledge.

932: Which one of the following CANNOT be prevented by the Secure Shell (SSH) program? A. Internet Protocol (IP) spoofing. B. Data manipulation during transmissions. C. Network based birthday attack. D. Compromise of the source/destination host.

D This is a question that I disagreed with. The premises that SSH does use RSA and 3DES, thus susceptible to cryptographic attack (namely birthday attach) has merit but I think the answer is more simple, in that you SSH cant protect against a compromised source/destination. You can safely rule out spoofing and manipulation (that is the job of ssh to protect the transmission). Original answer was C birthday attack. Use your best judgment based on knowledge and experience. CISSP Actualtests.com - The Power of Knowing The use of ssh helps to correct these vulnerabilities. Specifically, ssh protects against these attacks: IP spoofing (where the spoofer is on either a remote or local host), IP source routing, DNS spoofing, interception of cleartext passwords/data and attacks based on listening to X authentication data and spoofed connections to an X11 server. http://www-arc.com/sara/cve/SSH_vulnerabilities.html Birthday attack - Usually applied to the probability of two different messages using the same hash fucntion that produces a common message digest; or given a message and its corresponding message digest, finding another message that when passed through the same hash function generates the same specific message digest. The term "birthday" comes from the fact that in a room with 23 people, the probability of two people having the same birthday is great than 50 percent. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 212

569: When establishing a violation tracking and analysis process, which one of the following parameters is used to keep the quantity of data to manageable levels? A. Quantity baseline B. Maximum log size C. Circular logging D. Clipping levels

D To make violation tracking effective, clipping levels must be established. A clipping level is a baseline of user activity that is considered a routine level of user errors. When a clipping level is exceeded, a violation record is then produced. Clipping levels are also used for variance detection. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 318

1362: Which type of network topology passes all traffic through all active nodes? A. Broadband B. Star C. Baseband D. Token Ring CISSP Actualtests.com - The Power of Knowing

D Token ring passes all traffic through nodes.

913: Why are hardware security features preferred over software security features? A. They lock in a particular implementation. B. They have a lower meantime to failure. C. Firmware has fever software bugs. D. They permit higher performance.

D This is a sort of iffy question. Hardware allows faster performance then software and does not need to utilize an underlying OS to make the security software operate. (An example is PIX firewall vs checkpoint). The meantime to failure answer to me is ok but the hardware that the software security also has a MTFF. A few people looked over this question and had no problem with the answer of B (meantime to failure question) but as I looked into it I have picked D. MTTF is typical the time to failure. "MTFF is the expected typical functional lifetime of the device given a specific operating environment" (- Ed Tittle CISSP Study Guide (sybex) pg 657). This leads me to think that this question says hardware has a SHORTER lifespan then software. Thus I am going to have to go with D (higher performance). This can be because of ASICs. As always uses your best judgment, knowledge and experience on this question. Below are some points of view. Few things to consider when deploying software based firewall: Patching OS or firewall software could bring down firewall or open additional holes OS Expertise vs. firewall expertise (you may need two administrators). CISSP Actualtests.com - The Power of Knowing Support contract (One for hardware, one for OS, one for firewall), who do you call? Administration (One for OS and one for firewall). If your not an expert in both then forget it. High-availability (Stateful failover) (usually requires additional software and costs a lot of money). As a result it adds to support costs. Is software firewalls a bad idea it depends. Every situation is different. -Bob http://www.securityfocus.com/archive/105/322401/2003-05-22/2003-05-28/2 A software firewall application is designed to be installed onto an existing operating system running on generic server or desktop hardware. The application may or may not 'harden' the underlying operating system by replacing core components. Typical host operating systems include Windows NT, 2000 server or Solaris. Software firewall applications all suffer from the following key disadvantages: They run on a generic operating system that may or may not be hardened by the Firewall installation itself. A generic operating system is non-specialized and more complex than is necessary to operate the firewall. This leads to reliability problems and hacking opportunities were peripheral/unnecessary services are kept running. Generic operating systems have their own CPU and memory overheads making software based firewalls slower than their dedicated hardware counterparts. If the software firewalls uses PC hardware as the host platform, then there may be additional reliability problems with the hardware itself. Sub-optimal performance of generic hardware also affects software applications bundled with their own operating systems. There is no physical or topological separation of the firewalling activity. A dedicated hardware firewall is a software firewall application and operating system running on dedicated hardware. This means the hardware used is optimized for the task, perhaps including digital signal processors (DSPs) and several network interfaces. There may also be special hardware used to accelerate the encryption/decryption of VPN data. It may be rack mounted for easy installation into a comms' cabinet. We recommend dedicated hardware firewalls as they offer several key advantages over software applications: Dedicated hardware is typically more reliable. Hardware firewalls are simpler, hence more secure. Hardware firewalls are more efficient and offer superior performance, especially in support of VPNs. The firewalling activity is physically and topologically distinct. http://www.zensecurity.co.uk/default.asp?URL=hardware%20software%20firewall

1161: What is the ALE?

Explanation: Determine annual loss expectancy (ALE)-This third and final step of the quantitative assessment seeks to combine the potential loss and rate per year to determine the magnitude of the risk. This is expressed as annual loss expectancy (ALE). ALE is calculated as follows: Annualized loss expectancy (ALE) x Single loss expectancy (SLE) = Annualized rate of occurrence (ARO)

1160: What is the SLE?

Explanation: Single Loss Expectancy (SLE) Estimate potential losses (SLE)-this step involves determining the single loss expectancy (SLE). SLE is calculated as follows: Single loss expectancy x Asset value = Exposure factor Items to consider when calculating the SLE include the physical destruction or theft of assets, the loss of data, the theft of information, and threats that might cause a delay in processing. The exposure factor is the measure or percent of damage that a realized threat would have on a specific asset.

1159: A product cost $20,000. The cost to restore information is $1,000,000. The product is 60% effective. What is the value of the product in 2 years?

Explanation: This question makes no sense. There are some questions on the actual CISSP exam that are not used for research only purposes and are not used to grade the exam.. This problem is not a SLE, because SLE pertains to a one year period of time. Based on the information provided the value of the product could be lower or higher due to market demands. This question has more to do with economics then SLE. CISSP Actualtests.com - The Power of Knowing

1194: Phreakers are hackers who specialize in telephone fraud. What type of telephone fraud simulates the tones of coins being deposited into a payphone? A. Red Boxes B. Blue Boxes C. White Boxes D. Black Boxes

A Explanation: The Red box basically simulates the sounds of coins being dropped into the coin slot of a payphone. The traditional Red Box consisting of a pair of Wien-bridge oscillators with the timing controlled by 555 timer chips.The Blue Box, The mother of all boxes, The first box in history, which started the whole phreaking scene. Invented by John Draper (aka "Captain Crunch") in the early 60s, who discovered that by sending a tone of 2600Hz over the telephone lines of AT&T, it was possible to make free calls.A Black Box is a device that is hooked up to your phone that fixes your phone so that when you get a call, the caller doesn't get charged for the call. This is good for calls up to 1/2 hour, after 1/2 hour the Phone Co. gets suspicious, and then you can guess what happens.The White Box turns a normal touch tone keypad into a portable unit. This kind of box can be commonly found in a phone shop.

589: Which of the following are security events on Unix that should be logged? A. All of the choices. B. Use of Setgid. C. Change of permissions on system files. D. Use of Setuid.

A Explanation: The following file changes, conditions, and events are logged: .rhosts. UNIX Kernel. /etc/password. rc directory structure. bin files. lib files. Use of Setuid. Use of Setgid. Change of permission on system or critical files.

1206: Most of unplanned downtime of information systems is attributed to which of the following? A. Hardware failure B. Natural disaster C. Human error D. Software failure CISSP Actualtests.com - The Power of Knowing

A Explanation: This is what the static's says. Most of the downtime is cause of unexpected hardware failure. Commonly you just replace the FRU (Field replazable unit) when they fail. Usually a well written software does not fail if the hardware is running correctly. The human errors are controllable and natural disasters are not very often. Hardware failure is very common, it's a good practice to have spare disks, NIC and any other hardware FRU´s in your company to minimize the downtime with quick replacements.

399: With RBAC, each user can be assigned: A. One or more roles. B. Only one role. C. A token role. D. A security token.

A Explanation: With RBAC, security is managed at a level that corresponds closely to the organization's structure. Each user is assigned one or more roles, and each role is assigned one or more privileges that are permitted to users in that role. Roles can be hierarchical.

1343: Primary run when time and tape space permits, and is used for the system archive or baselined tape sets is the? A. Full backup method. B. Incremental backup method. C. Differential backup method. D. Tape backup method.

A Explanation: "Full" backup method provides a baseline for our systems for Restore; the full backup must be done at least once regardless of the method you are using to make backups. It's very common to use full backups in combination with incremental or differential ones to decrease the backup time (however you increment the restore time with incremental and differential) because it takes the largest time to complete. You always need to begin a system restoration from your baseline, and this baseline is the Full Backup.

1326: A server cluster looks like a? A. Single server from the user's point of view. B. Dual server from the user's point of view. C. Tripe server from the user's point of view. D. Quardle server from the user's point of view.

A Explanation: A "Cluster" is a grouping of machines running certain services providing high availability and fault tolerance fro them. In other words, they are grouped together as a means of fail over support. From the users view, a cluster is a single server, but its only a logical one, you can have an array of 4 server in cluster all with the same IP address (/achieving correct resolution through ARP), there is no difference for the client.

1323: This tape format can be used to backup data systems in addition to its original intended audio used by: A. Digital Audio tape (DAT) B. Digital video tape (DVT) C. Digital Casio Tape (DCT) D. Digital Voice Tape (DVT)

A Explanation: Digital Audio Tape (DAT or R-DAT) is a signal recording and playback medium introduced by Sony in 1987. In appearance it is similar to a compact audio cassette, using 1/8" magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm x 54 mm x 10.5 mm. As the name suggests the recording is digital rather than analog, DAT converting and recording at the same rate as a CD (44.1 kHz sampling rate and 16 bits quantization) without data compression. This means that the entire input signal is retained. If a digital source is copied then the DAT will produce an exact clone. The format was designed for audio use, but through an ISO standard it has been adopted for general data storage, storing from 4 to 40 GB on a 120 meter tape depending on the standard and compression (DDS-1 to DDS-4). It is, naturally, sequential-access media and is commonly used for backups. Due to the higher requirements for integrity in data backups a computer-grade DAT was introduced.

1221: The guarantee that the message sent is the message received, and that the message was not intentionally or unintentionally altered is? A. Integrity B. Confidentiality C. Availability D. Identity

A Explanation: Here are 2 definitions for Data Integrity: 1. The condition existing when data is unchanged from its source and has not been accidentally or maliciously modified, altered, or destroyed. 2. The condition in which data are identically maintained during any operation, such as transfer, storage, and retrieval. Availability refers to get access to data when and where you need it. Confidentiality deals with encryption and data protection against third party interception. Identity deals with authentication. CISSP Actualtests.com - The Power of Knowing

1336: In the OSI / ISO model, at what layer are some of the SLIP, CSLIP, PPP control functions are provided? A. Link B. Transport C. Presentation D. Application

A Explanation: The Data Link layer takes raw data from the physical layer and gives it logical structure. This logic includes information about where the data is meant to go, which computer sends the data, and the overall validity of the bytes sent. The Data Link layer also controls functions of logical network topologies and physical addressing as well as data transmission synchronization and corrections. SLIP, CSLIP and PPP provide control functions at the Data Link Layer (layer 2 of the OSI model).

1279: Which of the following is an advantage of prototyping? A. Prototype systems can provide significant time and cost savings. B. Change control is often less complicated with prototype systems. C. It ensures that functions or extras are not added to the intended system. D. Strong internal controls are easier to implement.

A Explanation: The Prototype Phase is also called the "Proof of Concept" Phase. Whether it's called one or the other depends on what the creator is trying to "prove." If the main deliverable of the Phase includes a working version of the product's technical features, it's a "prototype." If the main deliverable just looks like it has the product's technical features, then it's a "proof of concept." Prototypes can save time and money because you can test some functionality earlier in the process. You don't have to make the whole final product to begin testing it.

1332: Which of the following goals is NOT a goal of Problem Management? A. To eliminate all problems. B. To reduce failures to a manageable level. C. To prevent the occurrence or re-occurrence of a problem. D. To mitigate the negative impact of problems on computing services and resources.

A Explanation: This is not possible, nobody can eliminate all problems, only god can, this is a reality and Problem Management Gurus know that. With problem management we can reduce failures, prevent reoccurrence of problems and mitigate negative impact as much as we can, but we cannot eliminate all problems, this is not a perfect world.

1318: The structures, transmission methods, transport formats, and security measures that are used to provide integrity, availability, authentication, and confidentiality for transmissions over private and public communications networks and media includes? A. The Telecommunications and Network Security domain. B. The Telecommunications and Netware Security domain. C. The Technical communications and Network Security domain. D. The Telnet and Network Security domain.

A Explanation: This is pretty straight forward. The four principal pillars of computer security: integrity, authentication, confidentiality and availability are all part of the network security and telecommunication domain. Why? Because those pillars deal with that. We provide integrity through digital signatures, authentication through passwords, confidentiality through encryption and availability by fault tolerance and disaster recovery. All of those are networking and telecommunication components.

1325: Guards are appropriate whenever the function required by the security program involves which of the following? A. The use of discriminating judgment. B. The use of physical force. C. The operation of access control devices. D. The need to detect unauthorized access.

A Explanation: This is the correct answer, we don't have guards only to use physical force, that is not the real functionality of them if your security policy is well oriented. They are not only there to operate control devices and to detect unauthorized access, as stated in CISSP documentation, the appropriate function of a guard inside a security program is the use of discriminating judgment.

1258: Which of the following protocols is not implemented at the Internet layer of the TCP/IP protocol model? A. User datagram protocol (UDP) B. Internet protocol (IP) C. Address resolution protocol (ARP) D. Internet control message protocol (ICMP)

A Explanation: UDP (User Datagram Protocol) is a communications method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one computer to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn't provide sequencing of the packets that the data arrives in. UDP is implemented at the Transport layer of the TCP/IP protocol model.

424: A department manager has read access to the salaries of the employees in his/her department but not to the salaries of employees in other departments. A database security mechanism that enforces this policy would typically be said to provide which of the following? A.) content-dependent access control B.) context-dependent access control C.) least privileges access control D.) ownership-based access control

A "Database security takes a different approach than operating system security. In an operating system, the identity and authentication of the subject controls access. This is done through access control lists (ACLs), capability tables, roles, and security labels. The operating system only makes decisions about where a subject can access a file; it does not make this decisions based on the contents of the file itself. If Mitch can access file A, it does not matter if that file contains information about a cookie recipe or secret information from the Cold War. On the other hand, database security does look at the contents of a file when it makes an access control decision, which is referred to as content-dependent access control. This type of access control increases processing overhead, but it provides higher granular control." Pg. 677 Shon Harris: CISSP Certification All-in-One Exam Guide

111: Which of the following ensures that security is not breached when a system crash or other system failure occurs? A.) trusted recovery B.) hot swappable C.) redundancy D.) secure boot

A "Trusted Recovery When an operating system or application crashes or freezes, it should not put the sytem in any time of secure state." Pg 762 Shon Harris: All-In-One CISSP Certification Exam Guide

791: Which security measure BEST provides non-repudiation in electronic mail? A. Digital signature B. Double length Key Encrypting Key (KEK) C. Message authentication D. Triple Data Encryption Standard (DES)

A A tool used to provide the authentication of the sender of a message. It can verify the origin of the message along with the identity of the sender. IT is unique for every transaction and created with a private key. - Shon Harris All-in-one CISSP Certification Guide pg 930 "Secure Multipurpose Internet Mail Extensions (S/MIME) offers authentication and privacy to e-mail through secured attachments. Authentication is provided through X.509 digital certificates. Privacy is provided through the use of Public Key Cryptography Standard (PKCS) Enryption. Two types of messages can be formed using S/MIME: signed messages and enveloped messages. A signed message provides integrity and sender authentication. An CISSP Actualtests.com - The Power of Knowing enveloped message provides ntegrity, sender authentication, and confidentiality." Pg 123 Tittle: CISSP Study Guide

1405: Which agency shares the task of investigating computer crime along with the FBI? CISSP Actualtests.com - The Power of Knowing A. Secret Service B. CIA C. Department of justice D. Police force E. NSA

A Along with the FBI, the Secret Service has been given the authority to investigate computer crime.

726: Which of the following defines the key exchange for Internet Protocol Security (IPSEC)? A. Internet Security Association Key Management Protocol (ISAKMP) B. Internet Key Exchange (IKE) C. Security Key Exchange (SKE) D. Internet Communication Messaging Protocol (ICMP)

A Because Ipsec is a framework, it does not dictate what hashing and encryption algorithms are to be used or how keys are to be exchanged between devices. Key management can be handled through manual process or automated a key management protocol.

1329: The Computer Security Policy Model the Orange Book is based on is which of the following? A. Bell-LaPadula B. Data Encryption Standard C. Kerberos D. Tempest

A CISSP Actualtests.com - The Power of Knowing Explanation: Following the publication of the Anderson report, considerable research was initiated into formal models of security policy requirements and of the mechanisms that would implement and enforce those policy models as a security kernel. Prominent among these efforts was the ESD-sponsored development of the Bell and LaPadula model, an abstract formal treatment of DoD security policy.[2] Using mathematics and set theory, the model precisely defines the notion of secure state, fundamental modes of access, and the rules for granting subjects specific modes of access to objects. Finally, a theorem is proven to demonstrate that the rules are security-preserving operations, so that the application of any sequence of the rules to a system that is in a secure state will result in the system entering a new state that is also secure. This theorem is known as the Basic Security Theorem.

B Explanation: Keystroke dynamics looks at the way a person types at a keyboard. Specifically, keyboard dynamics measures two distinct variables: "dwell time" which is the amount of time you hold down a particular key and "flight time" which is the amount of time it takes a person to switch between keys. Keyboard dynamics systems can measure one's keyboard input up to 1000 times per second.

352: What type of attacks occurs when a smartcard is operating under normal physical conditions, but sensitive information is gained by examining the bytes going to and from the smartcard? A. Physical attacks. B. Logical attacks. C. Trojan Horse attacks. D. Social Engineering attacks.

B Explanation: Logical attacks occur when a smartcard is operating under normal physical conditions, but sensitive information is gained by examining the bytes going to and from the smartcard. One example is the so-called "timing attack" described by Paul Kocher. In this attack, various byte patterns are sent to the card to be signed by the private key. Information such as the time required to perform the operation and the number of zeroes and ones in the input bytes are used to eventually obtain the private key. There are logical countermeasures to this attack but not all smartcard manufacturers have implemented them. This attack does require that the PIN to the card be known, so that many private key operations can be performed on chosen input bytes.

198: Which of the following is true about MAC? A. It is more flexible than DAC. B. It is more secure than DAC. C. It is less secure than DAC. D. It is more scalable than DAC.

B Explanation: Mandatory controls are access controls that are based on a policy that the user, and more importantly the processes running with that user's privileges, is not allowed to violate. An example of this is "Top Secret" data is configured so that regardless of what the user does, the data cannot be transmitted to someone who does not have "Top Secret" status. Thus no "trojan horse" program could ever do what the user is not allowed to do anyway. The restrictions of mandatory controls are (at least in normal mode) also applied to the user who in a discretionary system would be "root", or the superuser.

1214: Business continuity plan development depends most on? A. Directives of Senior Management B. Business Impact Analysis (BIA) C. Scope and Plan Initiation D. Skills of BCP committee

B Explanation: Business continuity is of course a vital activity. However, prior to the creation of a business continuity plan, it is essential to consider the potential impacts of disaster and to understand the underlying risks. It is now widely accepted that both business impact analysis and risk analysis are vital components of the business continuity process. However, many organizations are unsure of how to approach these important disciplines. BIA is important because it provides management level analysis by which an organization assesses the quantitative (financial) and qualitative (non-financial) impacts, effects and loss that might result if the organization were to suffer a Business Continuity E/I/C. The findings from a BIA are used to make decisions concerning Business Continuity Management strategy and solutions.

220: Which of the following security modes of operation involved the highest risk? A.) Compartmented Security Mode B.) Multilevel Security Mode C.) System-High Security Mode D.) Dedicated Security Mode

B "Security Modes In a secure environment, information systems are configured to process information in one of four security modes. These modes are set out by the Department of Defense as follows: Systems running compartmental security mode may process two or more types of compartmented information. All system users must have an appropriate clearance to access all information processed by the system but do not necessarily have a need to know all of the information in the system. Compartments are subcategories or compartments within the different classification levels and extreme care is taken to preserve the information within the different compartments. The system may be classified at the Secret level but contain five different compartments, all classified Secret. If a user has only the need to know about two of the five different compartments to do their job, that user can access the system but can only access the two compartments. Compartmented systems are usually dedicated systems for each specific compartment to prevent the chance of any errors, because compartmentalization is the most CISSP Actualtests.com - The Power of Knowing secret of all the secrets. Systems running in the dedicated security mode are authorized to process only a specific classification level at a time, and all system users must have clearance and a need to know that information. Systems running in multilevel security mode are authorized to process information at more than one level of security even when all system users do not have appropriate clearances or a need to know for all information processed by the system. Systems running in system-high security mode are authorized to process only information that all system users are cleared to read and to have a valid need to know. These systems are not trusted to maintain separation between security levels, and all information processed by these systems must be handled as if it were classified at the same level as the most highly classified information processed by the system."

1153: Which one of these is a basic firewall? A. Packet Filtering Firewalls B. Proxy Firewalls C. All of the above D. None of the above

A Explanation: Packet Filtering Firewall - only examines an IP packet based on Source IP (SIP), Destination IP (DIP), Source Port and Destination Port for both UDP and TCP by subjecting each IP packet to an Access Control List.

1257: Which of the following is true related to network sniffing? A. Sniffers allow an attacker to monitor data passing across a network. B. Sniffers alter the source address of a computer to disguise and exploit weak authentication CISSP Actualtests.com - The Power of Knowing methods, C. Sniffers take over network connections. D. Sniffers send IP fragments to a system that overlap with each other.

A Explanation: Sniffing is the action of capture / monitor the traffic going over the network. Because, in a normal networking environment, account and password information is passed along Ethernet in clear-text, it is not hard for an intruder to put a machine into promiscuous mode and by sniffing, compromise all the machines on the net by capturing password in an illegal fashion.

1262: A packet filtering firewall looks at the data packet to get information about the source and destination addresses of an incoming packet, the session's communications protocol (TCP, UDP CISSP Actualtests.com - The Power of Knowing or ICMP), and the source destination application port for the? A. Desired service B. Dedicated service C. Delayed service D. Distributed service.

A Explanation: This is true, the packets filters show the desired service port (Remember that they are layer 3 devices), this is because you can have many different referenced port number in the destination port field of the different packets. You have to look for the well-known port numbers of the service desired. For example, look in port 80 for HTTP and port 21 for FTP. This is the correct terminology, see the features of Packet Filters in your CISSP documentation.

A Explanation: Logging is the activity that consists of collecting information that will be used for monitoring and auditing. Detailed logs combined with active monitoring allow detection of security issues before they negatively affect your systems.

235: Which of the following will you consider as the MOST secure way of authentication? A. Biometric B. Password C. Token D. Ticket Granting

A Explanation: Biometric authentication systems take advantage of an individual's unique physical characteristics in order to authenticate that person's identity. Various forms of biometric authentication include face, voice, eye, hand, signature, and fingerprint, each have their own advantages and disadvantages. When combined with the use of a PIN it can provide two factors authentication.

242: Biometric performance is most commonly measured in terms of: A. FRR and FAR B. FAC and ERR C. IER and FAR D. FRR and GIC

A Explanation: Biometric performance is most commonly measured in two ways: False Rejection Rate (FRR), and False Acceptance Rate (FAR). The FRR is the probability that you are not authenticated to access your account. A strict definition states that the FRR is the probability that a mated comparison (i.e. 2 biometric samples of the same finger) incorrectly determines that there is no match.

449: What are edit controls? A.) Preventive controls B.) Detective controls C.) Corrective controls D.) Compensating controls

A Explanation: CISSP Actualtests.com - The Power of Knowing "Challenge Handshake Authentication Protocol (CHAP) One of the authentication protocols used over PPP links. CHAP encrypts usernames and passwords." Pg. 682 Glossary: Tittel: CISSP Study Guide

650: As a type of access control, which of the following asks for avoiding occurrence? A. Preventive B. Deterrent C. Intrusive D. Detective

A Explanation: CISSP Actualtests.com - The Power of Knowing There are different types of access control. Access controls can be categorized as follows: Preventive (in order to avoid occurrence) Detective (in order to detect or identify occurrences) Deterrent (in order to discourage occurrences) Corrective (In order to correct or restore controls) Recovery (in order to restore resources, capabilities, or losses)

227: What is an indirect way to transmit information with no explicit reading of confidential information? A. Covert channels B. Backdoor C. Timing channels D. Overt channels

A Explanation: Covert channels: indirect ways for transmitting information with no explicit reading of confidential information. This kind of difficulties induced some researchers to re-think from scratch the whole problem of guaranteeing security in computer systems.

1051: Individuals who have their sole aim as breaking into a computer system are being referred to as: A. Crackers B. Sniffers C. Hackers D. None of the choices.

A Explanation: Crackers are individuals who try to break into a computer system. The term was coined in the mid-80s by hackers who wanted to differentiate themselves from individuals whose sole purpose is to sneak through security systems. Whereas crackers sole aim is to break into secure systems, hackers are more interested in gaining knowledge about computer systems and possibly using this knowledge for playful pranks. Although hackers still argue that there's a big difference between what they do and what crackers do, the mass media has failed to understand the distinction, so the two terms -- hack and crack -- are often used interchangeably.

669: Closed circuit TV is a feature of: A. Detective Physical Controls B. Corrective Physical Controls C. Corrective Logical Controls D. Logical Physical Controls

A Explanation: Detective Physical Controls would use the following: motion detectors, closed circuit TV, sensors, and alarms.

1321: The basic function of an FRDS is to? A. Protect file servers from data loss and a loss of availability due to disk failure. B. Persistent file servers from data gain and a gain of availability due to disk failure. C. Prudent file servers from data loss and a loss of acceptability due to disk failure. D. Packet file servers from data loss and a loss of accountability due to disk failure.

A Explanation: FRDS systems will give us the functionality to protect our servers from disk failure an allow us to have highly available file services in our production servers. FRDS provides high availability against many types of disk failures and well known problems, if one disk goes down, the others still work providing no downtime. FRDS solutions are the preferred way to protect file servers against data corruption and loss. You can see more about FRDS in the Internet, search "FRDS System".

368: What is known as decoy system designed to lure a potential attacker away from critical systems? A. Honey Pots B. Vulnerability Analysis Systems C. File Integrity Checker D. Padded Cells

A Explanation: Honey pots are decoy systems that are designed to lure a potential attacker away from critical systems. Honey pots are designed to: Divert an attacker from accessing critical systems, Collect information about the attacker's activity, and encourage the attacker to stay on the system long enough for administrators to respond.

549: When comparing host based IDS with network based ID, which of the following is an obvious advantage? A. It is unaffected by switched networks. B. It cannot analyze encrypted information. C. It is not costly to setup. D. It is not costly to manage.

A Explanation: Host-based IDSs are unaffected by switched networks. When Host-based IDSs operate on OS audit trails, they can help detect Trojan horse or other attacks that involve software integrity breaches. These appear as inconsistencies in process execution.

548: Host-based IDSs normally utilize information from which of the following sources? A. Operating system audit trails and system logs. B. Operating system audit trails and network packets. C. Network packets and system logs. D. Operating system alarms and system logs.

A Explanation: Host-based IDSs normally utilize information sources of two types, operating system audit trails, and system logs. Operating system audit trails are usually generated at CISSP Actualtests.com - The Power of Knowing the innermost (kernel) level of the operating system, and are therefore more detailed and better protected than system logs. However, system logs are much less obtuse and much smaller than audit trails, and are furthermore far easier to comprehend. Some host-based IDSs are designed to support a centralized IDS management and reporting infrastructure that can allow a single management console to track many hosts. Others generate messages in formats that are compatible with network management systems.

362: What is an important factor affecting the time required to perpetrate a manual trial and error attack to gain access to a target computer system? A. Keyspace for the password. B. Expertise of the person performing the attack. C. Processing speed of the system executing the attack. D. Encryption algorithm used for password transfer. CISSP Actualtests.com - The Power of Knowing

A Explanation: I am not sure of the answer on this question. B seems good but the reference below states that Keyspace (or length of password) is the main deterrent. I did not come across something that directly relates in my readings. "If an attacker mounts a trial-and-error attack against your password, a longer password gives the attacker a larger number of alternatives to try. If each character in the password may take on 96 different values (typical of printable ASCII characters) then each additional character presents the attacker with 96 times as many passwords to try. If the number of alternatives is large enough, the trial-and-error attack might discourage the attacker, or lead to the attacker's detection." http://www.smat.us/sanity/riskyrules.html

329: Identification usually takes the form of: A. Login ID. B. User password. C. None of the choices. D. Passphrase

A Explanation: Identification is a means to verify who you are. Authentication is what you are authorized to perform, access, or do. User identification enables accountability. It enables you to trace activities to individual users that may be held responsible for their actions. Identification usually takes the form of Logon ID or User ID. Some of the Logon ID characteristics are: they must be unique, not shared, and usually non descriptive of job function

605: If the computer system being used contains confidential information, users must not: A. Leave their computer without first logging off. B. Share their desks. C. Encrypt their passwords. D. Communicate

A Explanation: If the computer system being used or to which a user is connected contains sensitive or confidential information, users must not leave their computer, terminal, or workstation without first logging off. Users should be reminded frequently to follow this rule. CISSP Actualtests.com - The Power of Knowing

490: In order to avoid mishandling of media or information, you should consider using: A. Labeling B. Token C. Ticket D. SLL

491: In order to avoid mishandling of media or information, which of the following should be labeled? A. All of the choices. B. Printed copies C. Tape D. Floppy disks

A Explanation: In order to avoid mishandling of media or information, proper labeling must be used. All tape, floppy disks, and other computer storage media containing sensitive information must be externally marked with the appropriate sensitivity classification. All tape, floppy disks, and other computer storage media containing unrestricted information must be externally marked as such. All printed copies, printouts, etc., from a computer system must be clearly labeled with the proper classification. CISSP Actualtests.com - The Power of Knowing As a rule of thumb, you should have an indication of the classification of the document. The classification is based on the sensitivity of information. It is usually marked at the minimum on the front and back cover, title, and first pages.

541: What technology is being used to detect anomalies? A. IDS B. FRR C. Sniffing D. Capturing

A Explanation: Intrusion Detection is a quickly evolving domain of expertise. In the past year we have seen giant steps forward in this area. We are now seeing IDS engines that will detect anomalies, and that have some built-in intelligence. It is no longer a simple game of matching signatures in your network traffic.

389: Under MAC, classification reflects: A. Sensitivity B. Subject C. Privilege D. Object

A Explanation: It is important to note that mandatory controls are prohibitive (i.e., all that is not expressly permitted is forbidden), not permissive. Only within that context do discretionary controls operate, prohibiting still more access with the same exclusionary principle. In this type of control system decisions are based on privilege (clearance) of subject (user) and sensitivity (classification) of object (file). It requires labeling.

618: What are the benefits of job rotation? A. All of the choices. B. Trained backup in case of emergencies. C. Protect against fraud. D. Cross training to employees.

A Explanation: Job assignments should be changed periodically so that it is more difficult for users to collaborate to exercise complete control of a transaction and subvert it for fraudulent purposes. This principle is effective when used in conjunction with a separation of duties. Problems in effectively rotating duties usually appear in organizations with limited staff resources and inadequate training programs. Rotation pf duties will protect you against fraud; provide cross training to you employees, as well as assuring trained backup in case of emergencies.

259: In the world of keystroke dynamics, what represents the amount of time you hold down in a particular key? A. Dwell time B. Flight time C. Dynamic time D. Systems time

A Explanation: Keystroke dynamics looks at the way a person types at a keyboard. Specifically, keyboard dynamics measures two distinct variables: "dwell time" which is the amount of time you hold down a particular key and "flight time" which is the amount of time it takes a person to switch between keys. Keyboard dynamics systems can measure one's keyboard input up to 1000 times per second.

121: LOMAC is a security enhancement for what operating system? A. Linux B. Netware C. Solaris

A Explanation: LOMAC is a security enhancement for Linux that uses Low Water-Mark Mandatory Access Control to protect the integrity of processes and data from viruses, Trojan horses, CISSP Actualtests.com - The Power of Knowing malicious remote users and compromised root daemons. LOMAC is implemented as a loadable kernel module - no kernel recompilations or changes to existing applications are required. Although not all the planned features are currently implemented, it presently provides sufficient protection to thwart script-kiddies, and is stable enough for everyday use.

384: Under MAC, who may grant a right of access that is explicitly forbidden in the access control policy? A. None of the choices. B. All users. C. Administrators only. D. All managers.

A Explanation: MAC is defined as follows in the Handbook of Information Security Management: With mandatory controls, only administrators and not owners of resources may make decisions that bear on or derive from policy. Only an administrator may change the category of a resource, and no one may grant a right of access that is explicitly forbidden in the access control policy.

382: What defines an imposed access control level? A. MAC B. DAC C. SAC D. CAC

547: Which of the following is a drawback of Network-based IDSs? A. It cannot analyze encrypted information. B. It is very costly to setup. C. It is very costly to manage. D. It is not effective.

A Explanation: Network-based IDSs cannot analyze encrypted information. This problem is increasing as more organizations (and attackers) use virtual private networks. Most network-based IDSs cannot tell whether or not an attack was successful; they can only discern that an attack was initiated. This means that after a network-based IDS detects an attack, administrators must manually investigate each attacked host to determine whether it was indeed penetrated.

302: Within the Open Systems Interconnection (OSI) Reference Model, authentication addresses the need for a network entity to verify both CISSP Actualtests.com - The Power of Knowing A. The identity of a remote communicating entity and the authenticity of the source of the data that are received. B. The authenticity of a remote communicating entity and the path through which communications are received. C. The location of a remote communicating entity and the path through which communications are received. D. The identity of a remote communicating entity and the level of security of the path through which data are received.

A Explanation: OSI model needs to know the source of the data and that it is who it says it is. Path it the data take is not cared about unless source routing is used. The level of security is not cared about inherently by the receiving node (in general) unless configured. A is the best option in this question.

313: What are the valid types of one time password generator? A. All of the choices. B. Transaction synchronous C. Synchronous/PIN synchronous D. Asynchronous/PIN asynchronous

A Explanation: One-time Passwords are changed after every use. Handheld password generator (tokens) 3 basic types: Synchronous/PIN synchronous, Transaction synchronous, Asynchronous/PIN asynchronous.

358: Which of the following is an effective measure against a certain type of brute force password attack? A. Password used must not be a word found in a dictionary. B. Password history is used. C. Password reuse is not allowed. D. None of the choices.

A Explanation: Password reuse is not allowed (rotating passwords). Password history must be used to prevent users from reusing passwords. On all systems with such a facility the last 12 passwords used will be kept in the history. All computer system users must choose passwords that cannot be easily guessed. Passwords used must not be a word found in a dictionary.

312: Software generated passwords have what drawbacks? A. Passwords are not easy to remember. B. Password are too secure. C. None of the choices. D. Passwords are unbreakable.

A Explanation: Passwords generated by a software package or some operating systems. These password generators are good at producing unique and hard to guess passwords, however you must ensure that they are not so hard that people can't remember them. If you force your users to write their passwords down then you are defeating the purpose of having strong password management.

373: What type of attacks occurs when normal physical conditions are altered in order to gain access to sensitive information on the smartcard? A. Physical attacks B. Logical attacks C. Trojan Horse attacks D. Social Engineering attacks

A Explanation: Physical attacks occur when normal physical conditions, such as temperature, clock frequency, voltage, etc, are altered in order to gain access to sensitive information on the smartcard. Most smartcard operating systems write sensitive data to the EEPROM area in a proprietary, encrypted manner so that it is difficult to obtain clear text keys by directly hacking into the EEPROM. Other physical attacks that have proven to be successful involve an intense physical fluctuation at the precise time and location where the PIN verification takes place. Thus, sensitive card functions can be performed even though the PIN is unknown. This type of attack can be combined with the logical attack mentioned above in order to gain knowledge of the private key. Most physical attacks require special equipment.

266: In the process of facial identification, the basic underlying recognition technology of facial CISSP Actualtests.com - The Power of Knowing identification involves: A. Eigenfeatures of eigenfaces. B. Scanning and recognition. C. Detection and scanning. D. None of the choices.

A Explanation: Recognition is comparing the captured face to other faces that have been saved and stored in a database. The basic underlying recognition technology of facial feature identification involves either eigenfeatures (facial metrics) or eigenfaces. The German word "eigen" refers to recursive mathematics used to analyze unique facial characteristics.

610: Which of the following would be less likely to prevent an employee from reporting an incident? A.) They are afraid of being pulled into something they don't want to be involved with B.) The process of reporting incidents is centralized C.) They are afraid of being accused of something they didn't do D.) They are unaware of the company's security policies and procedures

A Explanation: Reference: ALL-IN-ONE CISSP Third Edition by Shon Harris Pg 783.

153: Which of the following focuses on the basic features and architecture of a system? A.) operational assurance B.) life cycle assurance C.) covert channel assurance D.) level A1 CISSP Actualtests.com - The Power of Knowing

A "The operational assurance requirements specified in the Orange Book are as follows: System Architecture System integrity Covert channel analysis Trusted facility management Trusted recovery" Pg. 301 Krutz: The CISSP Prep Guide: Gold Edition

196: Which of the following is a feature of the Rule based access control? A. The use of profile. B. The use of information flow label. C. The use of data flow diagram. D. The use of token.

A Explanation: Rule based access control is based on a specific profile for each user. Information can be easily changed for only one user but this scheme may become a burden in a very large environment. A rule-based access control unit will intercept every request to the server and compare the source specific access conditions with the rights of the user in order to make an access decision. A good example could be a firewall. Here a set of rules defined by the network administrator is recorded in a file. Every time a connection is attempted (incoming or outgoing), the firewall software checks the rules file to see if the connection is allowed. If it is not, the firewall closes the connection.

621: Which of the following are functions that are compatible in a properly segregated environment? A.) Security administration and quality assurance B.) Security administration and data entry C.) Security administration and application programming D.) Application programming and data entry

A Explanation: Security Administration and Quality Assurance are the most similar tasks. Administrative Management: Administrative management is a very important piece of operational security. One aspect of administrative management is dealing with personnel issues. This includes separation of duties and job rotation. The objective of separation of duties is to ensure that one person acting alone cannot compromise the company's security in any way. High-risk activities should be broken up into different parts and distributed to different individuals. This way the company does not need to put a dangerously high level of trust on certain individuals and if fraud were to take place, collusion would need to be committed, meaning more than one person would have to be involved in the fraudulent activity. Separation of duties also helps to prevent many different types of mistakes that can take place if one person is performing a task from the beginning to the end. For instance, a programmer should not be the one to test her own code. A different person with a different job and agenda should perform functionality and integrity testing on the programmer's code because the programmer may have a focused view of what the program is supposed to accomplish and only test certain functions, input values, and in certain environments. Another example of separation of duties is the difference between the functions of a computer operator versus the functions of a system administrator. There must be clear cut lines drawn between system administrator duties and computer operator duties. This will vary from environment to environment and will depend on the level of security required within the environment. The system administrators usually have responsibility of performing backups and recovery procedures, setting permissions, adding and removing users, setting user clearance, and developing user profiles. The computer operator on the other hand, may be allowed to install software, set an initial password, alter desktop configurations, and modify certain system parameters. The computer operator should not be able to modify her own security profile, add and remove users globally, or set user security clearance. This would breach the concept of separation of duties.

21: Security is a process that is: A. Continuous B. Indicative C. Examined D. Abnormal

A Explanation: Security is a continuous process; as such you must closely monitor your systems on a regular basis. Log files are usually a good way to find an indication of abnormal activities. However some care must be exercise as to what will be logged and how the logs are protected. Having corrupted logs is about as good as not having logs at all.

555: Which of the following is a valid tool that complements IDSs? A. All of the choices. B. Padded Cells C. Vulnerability Analysis Systems D. Honey Pots

A Explanation: Several tools exist that complement IDSs and are often labeled as intrusion detection products by vendors since they perform similar functions. They are Vulnerability CISSP Actualtests.com - The Power of Knowing Analysis Systems, File Integrity Checkers, Honey Pots, and Padded Cells. "IDS-Related Tools Intrusion detection systems are often deployed in concert with several other components. These IDS-related tools expand the usefulness and capabilities of IDSs and make IDSs more efficient and less prone to false positives. These tools include honey pots, padded cells, and vulenerability scanners." Pg. 46 Tittel: CISSP Study Guide

46: When conducting a risk assessment, which one of the following is NOT an acceptable social engineering practice? A. Shoulder surfing B. Misrepresentation C. Subversion D. Dumpster diving

A Explanation: Shoulder Surfing: Attackers can thwart confidentiality mechanisms by network monitoring, shoulder surfing, stealing password files, and social engineering. These topics will be address more in-depth in later chapters, but shoulder surfing is when a person looks over another person's shoulder and watches keystrokes or data as it appears on the screen. Social engineering is tricking another person into sharing confidential information by posing as an authorized individual to that information. Shon Harris: CISSP Certification pg. 63. Shoulder surfing is not social engineering.

300: Which of the following correctly describe the features of SSO? A. More efficient log-on. B. More costly to administer. C. More costly to setup. D. More key exchanging involved.

A Explanation: Single Sign-On (SSO) - This is a method for a users to identify and present credentials only once to a system. Information needed for future system access to resources is forwarded by the initial System. BENEFITS More efficient user log-on process Users select stronger passwords Inactivity timeout and attempt thresholds applied uniformly closer to user point of entry Improved timely disabling of all network/computer accounts for terminated users

339: Retinal scans check for: A. Something you are. B. Something you have. C. Something you know. D. All of the choices.

A Explanation: Something you are is really a special case of something you have. The usual examples given include fingerprint, voice, or retinal scans. CISSP Actualtests.com - The Power of Knowing

961: What attack is primarily based on the fragmentation implementation of IP? A. Teardrop B. Exhaustive C. Spoofing D. Brute force

A Explanation: Teardrop attack - This is based on the fragmentation implementation of IP whereby reassembly problems can cause machines to crash. The attack uses a reassembly bug with overlapping fragments and causes systems to hang or crash. It works for any Internet Protocol type because it hits the IP layer itself. Engineers should turn off directed broadcast capability.

177: What Access Control model was developed to deal mainly with information flow in computer systems? A. Lattice Based B. Integrity Based C. Flow Based D. Area Based

A Explanation: The Lattice Based Access Control model was developed to deal mainly with information flow in computer systems. Information flow is clearly central to confidentiality but to CISSP Actualtests.com - The Power of Knowing some extent it also applies to integrity. The basic work in this area was done around 1970 and was driven mostly by the defense sector. Information flow in computer systems is concerned with flow from one security class (also called security label) to another. These controls are applied to objects. An object is a container of information, and an object can be a directory or file.

176: Under the Lattice Based Access Control model, a container of information is a(n): A. Object B. Model C. Label

A Explanation: The Lattice Based Access Control model was developed to deal mainly with information flow in computer systems. Information flow is clearly central to confidentiality but to some extent it also applies to integrity. The basic work in this area was done around 1970 and was driven mostly by the defense sector. Information flow in computer systems is concerned with flow from one security class (also called security label) to another. These controls are applied to objects. An object is a container of information, and an object can be a directory or file.

409: With Rule Based Security Policy, a security policy is based on: A. Global rules imposed for all users. B. Local rules imposed for some users. C. Global rules imposed for no body. D. Global rules imposed for only the local users.

A Explanation: The RFC 2828 - Internet Security Glossary talks about Rule Based Security Policy: A security policy based on global rules imposed for all users. These rules usually rely on comparison of the sensitivity of the resource being accessed and the possession of corresponding attributes of users, a group of users, or entities acting on behalf of users.

1176: What is another name for the Orange Book? A. The Trusted Computer System Evaluation Criteria (TCSEC) B. The Trusted Computing Base (TCB) C. The Information Technology Security Evaluation Criteria (ITSEC) D. The Common Criteria

A Explanation: The Trusted Computer System Evaluation Criteria (TCSEC) is a collection of criteria used to grade or rate the security offered by a computer system product. The TCSEC is sometimes referred to as "the Orange Book" because of its orange cover. The current version is dated 1985 (DOD 5200.28-STD, Library No.S225,711) The TCSEC, its interpretations and guidelines all have different color covers, and are sometimes known as the "Rainbow Series".

585: To ensure dependable and secure logging, all computers must have their clock synchronized to: A. A central timeserver. B. The log time stamp. C. The respective local times. D. None of the choices.

A Explanation: The following pre-requisite must be met to ensure dependable and secure logging: All computers must have their clock synchronized to a central timeserver to ensure accurate time on events being logged. If possible all logs should be centralized for easy analysis and also to help detect patterns of abuse across servers. Logging information traveling on the network must be encrypted if possible. Log files are stored and protected on a machine that has a hardened shell. Log files must not be modifiable without a trace or record of such modification.

578: Which of the following should be logged for security problems? A. Use of mount command. B. Percentage of idle time. C. Percentage of use. D. None of the choices.

A Explanation: The level of logging will be according to your company requirements. Below is a list of items that could be logged, please note that some of the items may not be applicable to all operating systems. What is being logged depends on whether you are looking for performance problems or security problems. However you have to be careful about performance problems that could affect your security.

264: What are the advantages to using voice identification? A. All of the choices. B. Timesaving C. Reliability D. Flexibility

A Explanation: The many advantages to using voice identification include: Considered a "natural" biometric technology Provides eyes and hands-free operation Reliability Flexibility Timesaving data input Eliminate spelling errors Improved data accuracy

545: What is the most common way to classify IDSs? A. Group them by information source. B. Group them by network packets. C. Group them by attackers. D. Group them by signs of intrusion.

A Explanation: The most common way to classify IDSs is to group them by information source. Some IDSs analyze network packets, captured from network backbones or LAN segments, to find attackers. Other IDSs analyze information sources generated by the operating system or application software for signs of intrusion.

215: The access matrix model has which of the following common implementations? A. Access control lists and capabilities. B. Access control lists. C. Capabilities. D. Access control list and availability.

A Explanation: The two most used implementations are access control lists and capabilities. Access control lists are achieved by placing on each object a list of users and their associated rights to that object.

649: Which of the following is NOT a type of access control? A. Intrusive B. Deterrent C. Detective D. Preventive

A Explanation: There are different types of access control. Access controls can be categorized as follows: Preventive (in order to avoid occurrence) Detective (in order to detect or identify occurrences) Deterrent (in order to discourage occurrences) Corrective (In order to correct or restore controls) Recovery (in order to restore resources, capabilities, or losses)

654: What type of access control focuses on restoring resources? A. Recovery B. Preventive C. Intrusive D. Corrective

560: What are the primary approaches IDS takes to analyze events to detect attacks? A. Misuse detection and anomaly detection. B. Log detection and anomaly detection. C. Misuse detection and early drop detection. D. Scan detection and anomaly detection.

A Explanation: There are two primary approaches to analyzing events to detect attacks: misuse detection and anomaly detection. Misuse detection, in which the analysis targets something known to be "bad", is the technique used by most commercial systems. Anomaly detection, in which the analysis looks for abnormal patterns of activity, has been, and continues to be, the subject of a great deal of research. Anomaly detection is used in limited form by a number of IDSs. There are strengths and weaknesses associated with each approach, and it appears that the most effective IDSs use mostly misuse detection methods with a smattering of anomaly detection components.

832: Which of the following access methods is used by Ethernet? A.) CSMA/CD B.) CSU/DSU C.) TCP/IP D.) FIFO

A "Under the Ethernet CSMA/CD media-access process, any computer on a CSMA/CD LAN can access the network at any time." Pg. 103 Krutz: The CISSP Prep Guide. CISSP Actualtests.com - The Power of Knowing

1220: RAID Software can run faster in the operating system because neither use the hardware-level parity drives by? A. Simple striping or mirroring. B. Hard striping or mirroring. C. Simple hamming code parity or mirroring. D. Simple striping or hamming code parity.

A Explanation: This is true, if we do not use parity in our RAID implementation, like RAID 1 (Mirroring) or RAID 0 (Stripping) we can improve performance because the CPU does not need waste cycles to make the parity calculations. For example this can be achieved in Windows 2000 server through the use of RAID 0 (No fault tolerance, just stripping in 64kb chunks) or RAID 1 (Mirroring through a file system driver). This is not the case of RAID 5 that actually use parity to provide fault tolerance.

1248: The continual effort of making sure that the correct policies, procedures and standards are in place and being followed is described as what? A. Due care B. Due concern C. Due diligence D. Due practice

A Explanation: "Due care means that a company did all that it could have reasonable done to try and prevent security breaches, and also took the necessary steps to ensure that if a security breach did take place, the damages were reduced because of the controls or countermeasures that existed. Due care means that a company practiced common sense and prudent management practices with responsible actions. Due diligence meants that the company properly investigated all of their possible weaknesses and vulnerabilities before carrying out any due care practices. The following list describes some of the actions required to show that due care is being properly practiced in a corporation: CISSP Actualtests.com - The Power of Knowing Adequate physical and logical access controls Adequate telecommunication security, which could require encryption Proper information, application, and hardware backups Disaster recovery and business continuity plans Periodic review, drills, tests, and improvement in disaster recovery and business continuity plans Properly informing employees of expected behavior and ramifications of not following these expectations Developing a security policy, standards, procedures, and guidelines Performing security awareness training Running updated antivirus software Periodically performing penetration test from outside and inside the network Implementing dial-back or preset dialing features on remote access applications Abiding by and updating external service level agreements (SLAs) Ensuring that downstream security responsibilities are being met Implementing measure that ensure software piracy is not taking place Ensuring that proper auditing and reviewing of those audit logs are taking place Conducting background checks on potential employees" Pg. 616 Shon Harris: CISSP Certification All-in-One Exam Guide

1186: Which type of password provides maximum security because a new password is required for each now log-on is defined to as? A. One-time or dynamic password B. Cognitive password C. Static password D. Pass phrase

A Explanation: "One-time" or "dynamic" password technology concept is having your remote host already know a password that is not going to go over insecure channels and when you connect, you get a challenge. You take the challenge information and password and plug it into an algorithm which generates the response that should get the same answer if the password is the same on the both sides. Therefore the password never goes over the network, nor is the same challenge used twice. Unlike SecurID or SNK, with S/key you do not share a secret with the host. Other one time password technology is card systems where each user gets a card that generates numbers that allow access to their account. Without the card, it is improbable to guess the numbers.

1240: Database views are not used to: A. Implement referential integrity. B. Implement least privilege. C. To implement content-dependent access restrictions. D. Implement need-to-know.

A Explanation: A View is a display of one or more table shows that shows the table data. You can even retrieve part of the table and display the same to the user. Before a user is able to use a view, they must have both, permission on the view and all dependent objects. Views can also be used to implement security, for example you can create a view that only shows 3 of 5 columns contained in a table. Views are not used to provide integrity you can use constraints, rule or other components of database systems.

1236: Which of the following, used to extend a network, has a storage capacity to store frames and act as a store-and-forward device? A. Bridge B. Router C. Repeater D. Gateway

A Explanation: A bridge is a network device that connects two similar network segments together. The primary function of a bridge is to keep traffic separated on both sites of the bridge. Traffic is allowed to pass through the bridge only if the transmission is intended for a station in the opposite side. Bridges operate at the data link layer of the OSI model an provides two different collision domains in Ethernet, but they only provide one broadcast domain for layer 3 an up of the OSI model. The bridge can store frames and forward them in many forms like Cut-through and Store and Forward.

1196: Which of the following represents an ALE calculation? A. Singe loss expectancy x annualized rate of occurrence. B. Gross loss expectancy x loss frequency. C. Actual replacement cost - proceeds of salvage. D. Asset value x loss expectancy.

A Explanation: ALE (Annualized Loss Expectancy) calculations are a component of every risk analysis process. ALE calculations when done properly portray risk accurately. ALE calculations provide meaningful cost/benefit analysis. ALE calculations are used to: 1. Identify risks 2. Plan budgets for information risk management 3. Calculate loss expectancy in annualized terms SLE x ARO = ALE

1278: Which of the following is the most reliable, secure means of removing data from magnetic storage media such as a magnetic tape, or cassette? A. Degaussing B. Parity Bit Manipulation C. Certification D. Buffer overflow

A Explanation: An alternating current (AC) bulk eraser (degausser) is used for complete erasure of data and other signal on magnetic media. Degaussing is a process where magnetic media is exposed to a powerful, alternating magnetic field. Degaussing removes any previously written data, leaving the media in a magnetically randomized (blank) state. The degausser must subject the media to an alternating magnetic field of sufficient intensity to saturate the media and then by slowly withdrawing or reducing the field leaves the magnetic media in a magnetically neutral state.

1229: In what security mode can a system be operating if all users have the clearance or authorization and need-to-know to all data processed within the system? A. Dedicated security mode. B. System-high security mode. C. Compartmented security mode. D. Multilevel security mode.

A Explanation: An information-system (IS) security mode of operation wherein each user with direct or indirect access to the system, its peripherals, remote terminals, or remote hosts, has all of the Following: (a) a valid security clearance for all information within the system; (b) formal access approval and signed nondisclosure agreements for all the information stored and/or processed (including all compartments, sub compartments, and/or special access programs); and (c) a valid need_to_know for all information contained within the IS. When in the dedicated security mode, a system is specifically and exclusively dedicated to and controlled for the processing of one particular type or classification of information, either for full-time operation or for a specified period of time.

1291: Which of the following proves or disproves a specific act though oral testimony based on information gathered through the witness's five senses? A. Direct evidence B. Circumstantial evidence C. Conclusive evidence D. Corroborative evidence

A Explanation: As stated in the CISSP documentation, "If you want to make achieve the validation or revalidation of the oral testimony of a witness, you need to provide physical, direct evidence to backup your statements and override the five senses of an oral testimony". Circumstantial or Corroborative evidence is not enough in this case, we need direct, relevant evidence backing up the facts.

1217: Which of the following is a disadvantage of a behavior-based ID system? A. The activity and behavior of the users while in the networked system may not be static enough to effectively implement a behavior-based ID system. B. The activity and behavior of the users while in the networked system may be dynamic enough to effectively implement a behavior-based ID system. C. The activity and behavior of the users while in the networked system may not be dynamic enough to effectively implement a behavior-based ID system. D. The system is characterized by high false negative rates where intrusions are missed.

A Explanation: Behavior-based intrusion detection techniques assume that an intrusion can be detected by observing a deviation from normal or expected behavior of the system or the users. The model of normal or valid behavior is extracted from reference information collected by various means. The intrusion detection system later compares this model with the current activity. When a deviation is observed, an alarm is generated. In other words, anything that does not correspond to a previously learned behavior is considered intrusive. The high false alarm rate is generally cited as the main drawback of behavior-based techniques because the entire scope of the behavior of an information system may not be covered during the learning phase. Also, behavior can change over time, introducing the need for periodic online retraining of the behavior profile, resulting either in unavailability CISSP Actualtests.com - The Power of Knowing of the intrusion detection system or in additional false alarms. To get the most out of this kind of IDS you need to have very static behavior on your network and the user actions, this is because any new thing is considered dangerous, providing many false-positives but increased security. If you are in a very "dynamic" environment these kind of IDS system is not recommended.

1169: Which access control model enables the owner of the resource to specify what subjects can access specific resources? A. Discretionary Access Control B. Mandatory Access Control C. Sensitive Access Control D. Role-based Access Control

A Explanation: Discretionary Access Control (DAC) is used to control access by restricting a subject's access to an object. It is generally used to limit a user's access to a file. In this type of access control it is the owner of the file who controls other users' accesses to the file. Using a DAC mechanism allows users control over access rights to their files. When these rights are managed correctly, only those users specified by the owner may have some combination of read, write, execute, etc. permissions to the file.

1263: Packet Filtering Firewalls system is considered a? A. First generation firewall. B. Second generation firewall. C. Third generation firewall. D. Fourth generation firewall.

A Explanation: Firewall technology is a young but quickly maturing industry. The first generation of firewall architectures has been around almost as long as routers, first appearing around 1985 and coming out of Cisco's IOSsoftware division. These firewalls are called packet filter firewalls. However, the first paper describing the screening process used by packet filter firewalls did not appear until 1988, when Jeff Mogul from Digital Equipment Corporation published his studies. At this time we are in the Fourth generation of firewall devices and software.

1301: Which type of firewall can be used to track connectionless protocols such as UDP and RPC? A. Statefull inspection firewalls B. Packet filtering firewalls C. Application level firewalls D. Circuit level firewalls

A Explanation: Here are some characteristics of Statefull Inspection technology on Firewalls: 1. Scan information from all layers in the packet. 2. Save state information derived from previous communications, such as the outgoing Port command of an FTP session, so that incoming data communication can be verified against it. 3. Provides tracking support for connectionless protocols through the use of session state databases. 4. Allow state information derived from other applications access through the firewall for authorized services only, such as previously authenticated users. 5. Evaluate and manipulate flexible expressions based on communication and application derived state information.

1253: This type of backup management provides a continuous on-line backup by using optical or tape "jukeboxes", similar to WORMs, (Write Once, Read Many) A. Hierarchical Storage Management (HSM). B. Hierarchical Resource Management (HRM). C. Hierarchical Access Management (HAM). D. Hierarchical Instance Management (HIM).

A Explanation: Hierarchical Storage Management originated in the mainframe world where it was used to minimize storage costs. The HSM name signifies that the software has the intelligence to move files along a hierarchy of storage devices that are ranked in terms of cost per megabyte of storage, speed of storage and retrieval, and overall capacity limits. Files are migrated along the hierarchy to less expensive forms of storage based on rules tied to the frequency of data access. File migration and retrieval is transparent to users. Two major factors, data access response time and storage costs determine the appropriate combination of storage devices used in HSM. A typical three tier strategy may be composed of hard drives as primary storage on the file servers, rewritable optical as the secondary storage type, and tape as the final tertiary storage location. If faster access is required, a hard drive can be considered as an alternative to optical for secondary storage, and WORM (Write Once, Read Many) optical can also be implemented, in place of tape, as the final storage destination.

1249: Which tape format type is mostly used for home/small office backups? A. Quarter Inch Cartridge drives (QIC) B. Digital Linear Tapes (DLT) C. 8mm tape D. Digital Audio Tape (DAT)

A Explanation: QIC technology utilizates belt-driven dual-hub cartridges containing integral tape motion and guidance mechanisms, providing a rich spectrum of compatible solutions across a wide range of PC system platforms. QIC reliability is unsurpassed by any other removable storage technology. Reliability can be measured both in mean-time-between failure (MTBF) and, more practically, as a function of drive duty cycles. QIC has a worldwide installed base in excess of 15 million drives -- more than twice that of any alternate removable storage technology -- a level of acceptance that would have been unachievable without rock-solid reliability. QIC is the most common tape solution for SOHO.

1238: Access Control techniques do not include which of the following choices? A. Relevant Access Controls B. Discretionary Access Control C. Mandatory Access Control D. Lattice Based Access Control

A Explanation: Relevant Access Controls are not included as a Access Control Technique. Lattice-based access control models were developed in the early 1970s to deal with the confidentiality of military information. In the late 1970s and early 1980s, researchers applied these models to certain integrity concerns. Later, application of the models to the Chinese Wall policy, a confidentiality policy unique to the commercial sector, was demonstrated. Discretionary control is the most common type of access control mechanism implemented in computer systems today. The basis of this kind of security is that an individual user, or program operating on the user's behalf, is allowed to specify explicitly the types of access other users (or programs executing on their behalf) may have to information under the user's control. Discretionary Access control security differs from mandatory access control security in that it implements the access control decisions of the user. Mandatory controls are driven by the results of a comparison between the user's trust level or clearance and the sensitivity designation of the information.

1275: Which of the following steps should be performed first in a business impact analysis (BIA)? A. Identify all business units within the organization. B. Evaluate the impact of disruptive events. C. Estimate the Recovery Time Objectives (RTO). D. Evaluate the criticality of business functions.

A Explanation: Remember that when we talk about a BIA (Business Impact Analysis), we are CISSP Actualtests.com - The Power of Knowing analyzing and identifying possible issues about our infrastructure. It's an analysis about the business, the process that it relays on, the level of the systems and a estimative of the financial impact, or in other words, how much many we loose with our systems down. The first step on it should always be the identifying of the business units in the company. You can then go to other requirements like estimate losses and downtime costs.

1168: A Business Impact Analysis (BIA) does not: A. Recommend the appropriate recovery solution. B. Determine critical and necessary business functions and their resource dependencies. C. Identify critical computer applications and the associated outage tolerance. D. Estimate the financial impact of a disruption.

A Explanation: Remember that when we talk about a BIA (Business Impact Analysis), we are analyzing and identifying possible issues about our infrastructure, in this kind of analysis we don't make suggestions about what to do to recover from them. This is not an action plan, It's an analysis about the business, the process that it relays on, the level of the systems and a estimative of the financial impact, or in other words, how much many we loose with our systems down.

1340: Which of the following is used to create and delete views and relations within tables? A. SQL Data Definition Language B. SQL Data Manipulation Language C. SQL Data Relational Language D. SQL Data Identification Language

A Explanation: SQL supports the data definition language (DDL) for creating, altering, and deleting tables and indexes. SQL does not permit metadata object names to be represented by parameters in DDL statements. With this language you can create many of the objects used in SQL, this language is standard and is supported by most database vendors in its standard form. Many of them also extends its functionality for proprietary products.

1282: A circuit level gateway is ________ when compared to an application level firewall. A. Easier to maintain. B. More difficult to maintain. C. More secure. D. Slower

A Explanation: Since circuit level gateways are not as high in the OSI model for the inspection as Application level firewalls, they are easier to maintain and configure. Application layer firewalls are up to layer 7 of the OSI model and provide a great bunch of options and complex configurations. Application layer firewalls are more secure than circuit level gateway because they can track and analyze information up to layer 7, a drawback to this, is that this functionality makes them slower.

1312: This backup method must be made regardless of whether Differential or Incremental methods are used. A. Full Backup Method B. Incremental backup method C. Differential backup method D. Tape backup method CISSP Actualtests.com - The Power of Knowing

A Explanation: Since the "Full" backup method provides a baseline for our systems for Restore, the full backup must be done at least once regardless of the method you are using. Its very common to use full backups in combination with incremental or differential ones to decrease the backup time (however you increment the restore time), but there is no way to maintain a system only with incremental or differential backups. You always need to begin from your restore baseline, the Full Backup.

1192: Why does compiled code pose more risk than interpreted code? A. Because malicious code can be embedded in the compiled code and can be difficult to detect. B. Because the browser can safely execute all interpreted applets. CISSP Actualtests.com - The Power of Knowing C. Because compilers are not reliable. D. It does not. Interpreted code poses more risk than compiled code.

A Explanation: Since the compiled code has already been translated to binary language (the language understanded natively by the computers), its very difficult for us (the humans) to detect malicious code inside an application, this is because its not apparently visible, you have to find that malicious code through the behavior of the program. Instead, when we talk about Interpreted code, we use a language interpreter, that is a piece of software that allows the end-user to write a program in some human-readable language, and have this program executed directly by the interpreter. This is in contrast to language compilers, that translate the human-readable code into machine-readable code, so that the end-user can execute the machine-readable code at a later time.This is far more easier to detect malicious code inside the programs, you just need to see what piece of code produced the undesired action.

1224: Which of the following protocols operates at the session layer (layer 5)? A. RPC B. IGMP C. LDP D. SPX CISSP Actualtests.com - The Power of Knowing

A Explanation: The socket method of network use is a message-based system, in which one process writes a message to another. This is a long way from the procedural model. The remote procedure call is intended to act like a procedure call, but to act across the network transparently. The process makes a remote procedure call by pushing its parameters and a return address onto the stack, and jumping to the start of the procedure. The procedure itself is responsible for accessing and using the network. After the remote execution is over, the procedure jumps back to the return address. The calling process then continues. RPC works at the Session layer of the OSI model.

1330: Which type of attack would a competitive intelligence attack best classify as? A. Business attack B. Intelligence attack C. Financial attack D. Grudge attack

A Explanation: Since we are talking about a competitive intelligence attack, we can classify it as a Business attack because it is disrupting business activities. Intelligence attacks are one of the most commonly used to hurt a company where more it hurts, in its information. To see more about competitive intelligence attacks you can take a look at some CISSP study guide. It could be the CISSP gold edition guide. "Military and intelligence attacks are launched primarily to obtain secret and restricted information from law enforcement or military and technological research sources. Business attacks focus on illegally obtaining an organization's confidential information. Financial attacks are carried out to unlawfully obtain money or services. Grudge attacks are attacks that are carried out to damage an organization or a person." Pg. 616 Tittel: CISSP Study Guide

942: Which of the following is true related to network sniffing? A.) Sniffers allow an attacker to monitor data passing across a network. B.) Sniffers alter the source address of a computer to disguise and exploit weak authentication methods. C.) Sniffers take over network connections D.) Sniffers send IP fragments to a system that overlap with each other.

1242: Which of the following statements pertaining to the Trusted Computer System Evaluation Criteria (TCSEC) is incorrect? A. With TCSEC, functionality and assurance are evaluated separately. B. TCSEC provides a means to evaluate the trustworthiness of an information system. C. The Orange book does not cover networks and communications. CISSP Actualtests.com - The Power of Knowing D. Data base management systems are not covered by the TCSEC.

A Explanation: TCSEC does not separate functionality and assurance from evaluation. It makes them a combined criteria. Just to remember, The Trusted Computer System Evaluation Criteria (TCSEC) is a collection of criteria used to grade or rate the security offered by a computer system product. The TCSEC is sometimes referred to as "the Orange Book" because of its orange cover (Orange Book deals with networks and communications). The current version is dated 1985 (DOD 5200.28-STD, Library No.S225,711) The TCSEC, its interpretations and guidelines all have different color covers, and are sometimes known as the "Rainbow Series". Database management is also covered in TCSEC. The Orange Book is used to evaluate whether a product contains the security properties the vendor claims it does and whether the product is appropriate for a specific application or function. The Orange Book is used to review the functionality, effectiveness, and assurance of a product during its evaluation, and it uses classes that were devised to address typical patterns of security requirements. - Shon Harris, "CISSP All-in-One Exam Guide", 3rd Ed, p 302.

1205: The beginning and the end of each transfer during asynchronous communication data transfer are marked by? A. Start and Stop bits. B. Start and End bits. C. Begin and Stop bits. D. Start and Finish bits.

A Explanation: The ASYNCHRONOUS (ASYNC) format for data transmission is a procedure or protocol in which each information CHARACTER or BYTE is individually synchronized or FRAMED by the use of Start and Stop Elements, also referred to as START BITS and STOP BITS. The Asynchronous Transmission Format is also known as START-STOP mode or CHARACTER mode. Each character or byte is framed as a separate and independent unit of DATA that may be transmitted and received at irregular and independent time intervals. The characters or bytes may also be transmitted as a contiguous stream or series of characters.

1319: Which of the following is the lowest TCSEC class where in the system must protected against covert storage channels (but not necessarily covert timing channels)? A. B2 B. B1 C. B3 D. A1

A Explanation: The B2 class referenced in the orange book is the formal security policy model based on device labels that can use DAC (Discretionary access controls) and MAC (Mandatory Access Controls). It provides functionality about covert channel control. It does not require covert timing channels. You can review the B2 section of the Orange Book.

1188: Which of the following uses a directed graph to specify the rights that a subject can transfer to an object, or that a subject can take from another subject? A. Take-Grant model B. Access Matrix model C. Biba model D. Bell-Lapadula model

A Explanation: The Take-Grant System is a model that helps in determining the protection rights (e.g., read or write) in a computer system. The Take-Grant system was introduced by Jones, Lipton, and Snyder to show that it is possible to decide on the safety of a computer system even when the number of subjects and objects are very large, or unbound. This can be accomplished in linear time based on the initial size of the system. The take-grant system models a protection system which consists of a set of states and state transitions. A directed graph shows the connections between the nodes of this system. These nodes are representative of the subjects or objects of the model. The directed edges between the nodes represent the rights that one node has over the linked node.

1244: Which trusted facility management concept implies that two operators must review and approve the work of each other? CISSP Actualtests.com - The Power of Knowing A. Two-man control B. Dual control C. Double control D. Segregation control

A Explanation: The proper term for this trusted facility management concept is "Two-man Control", it means that two people must work and approve each others work to provide increased security and eliminate the possibility of one of them to hurt the company. For example they can only make changes to the system if both of them authenticate with their retina at the same time at the data center and enter their secret password This kind of work fashion is only used in highly secure environments, its not very common.

1306: Which of the following logical access exposures involves changing data before, or as it is entered into the computer? A. Data diddling B. Salami techniques C. Trojan horses D. Viruses

A Explanation: This kind of attack involves altering the raw data just before it is processed by a computer and then changing it back after the processing is completed. This kind of attack was used in the past to steal small quantities of money and transfer them to the attackers account, there are many other uses too. Trojan horses open ports without the user knowledge to permit remote control and a Virus is a malicious piece of code that executed inside your computer.

1166: Which of the following statements pertaining to dealing with the media after a disaster occurred and disturbed the organizations activities is incorrect? A. The CEO should always be the spokesperson for the company during a disaster. B. The disaster recover plan must include how the media is to be handled during the disaster. C. The organization's spokesperson should report bad news before the press gets a hold of it through another channel. D. An emergency press conference site should be planned ahead.

A Explanation: This is not a good practice, we cannot involves the CEO of the company to deal with the media in every case we have a disaster, depending on the severity of the disaster we can make the CEO talk, but the best practice in the real world is to have a well-known person with that role, with special speaking capabilities and knowledge about press methods. In general, the CEO always gets news of what happened, and he decides the company politics, then another designed employee (Usually from the disaster recovery team) deals with the media.

1285: Which of the following rules pertaining to a Business Continuity Plan/Disaster Recovery Plan is incorrect? A. In order to facilitate recover, a single plan should cover all locations. B. There should be requirements for to form a committee to decide a course of action. These decisions should be made ahead of time and incorporated into the plan. C. In its procedures and tasks, the plan should refer to functions, not specific individuals. D. Critical vendors should be contacted ahead of time to validate equipment can be obtained in a CISSP Actualtests.com - The Power of Knowing timely manner.

A Explanation: This is not the best practice, even more for the CISSP exam. Continuity / recovery plans should be make for every location in separate. This is because when there is a disaster, Its not usually in all the different locations, its better to have one plan for each of it so you can use and follow only the plan of the affected site and don't bother the other ones.

1316: Detection capabilities of Host-based ID systems are limited by the incompleteness of which of the following? A. Audit log capabilities B. Event capture capabilities C. Event triage capabilities D. Audit notification capabilities

A Explanation: This is one of the weakest point of IDS systems installed on the individual hosts. Since much of the malicious activity could be circulating through the network, and this kind of IDS usually have small logging capabilities and of local nature. So any activity happening in the network could go unnoticed, and intrusions can't be tracked as in depth as we could with an enterprise IDS solution providing centralized logging capabilities.

1198: Tape arrays use a large device with multiple (sometimes 32 or 64) tapes that are configured as a? A. Single array B. Dual array C. Triple array D. Quadruple array

A Explanation: This is the function of a tape robot/changer working on a media library / jukebox. We can get as many as 32 / 64 or even more tapes action as a single logical unit. You can have a robot that changes and retrieves the different tapes when they are needed, so you see the whole bunch of tapes as it's a single logical storage solution for you. This kind of solutions are very expensive.

1190: CISSP Actualtests.com - The Power of Knowing Zip/Jaz drives, SyQuest, and Bemoulli boxes are very transportable and are often the standard for? A. Data exchange in many businesses. B. Data change in many businesses. C. Data compression in many businesses. D. Data interchange in many businesses.

A Explanation: This is the primary use of this kind of devices, since they are very portable (a medium-size external box) and they provide standard interfaces to the PC, they are usually used in data exchange because of their high capacity in comparison to the 3.5 floppy diskettes. We can make changes in the media used by this devices, but is not their primary use. Compression is not the best feature of this devices, their usually depend on File system compression. Absolutely, the best use of this boxes is for data exchange.

1202: Which of the following evaluates the product against the specification? A. Verification B. Validation CISSP Actualtests.com - The Power of Knowing C. Concurrence D. Accuracy

A Explanation: This is the proper term, "Verification", this term is used when we are making a comparison of a product against a specification. For example, you can have a product that is build on open standards, you can have a proof of that by making a "verification" of it against the standards or specifications included in those.

1338: With RAID Level 5 the spare drives that replace the failed drives are usually hot swappable, meaning the can be replaced on the server while the? A. System is up and running. B. System is down and running. C. System is in-between and running. D. System is centre and running.

A Explanation: This is true, since RAID 5 uses parity to provide fault tolerance through the array, once of the disk in it can become corrupted, and you usually can just take it out without turning off the system (Hot SWAP) and plug a spare disk on the bay. Then the array will automatically begin to reconstruct the information in the new disk with the parity contained through the other disks in the array. This Hot Swap capability is usually present in enterprise servers that require high availability.

1181: Rewritable and erasable (CDR/W) optical disk are sometimes used for backups that require short time storage for changeable data, but require? A. Faster file access than tape. B. Slower file access than tape. C. Slower file access than drive. D. Slower file access than scale.

A Explanation: This is true, when we use optical media like CD´s to make our backups we need a constant throughput on the file access and data transfer inside the disk because of the risk to get a buffer overrun error in the CD writer. If the buffer user by the CD burner is empty and the Hard disk does not provide data for that time, the Backup will be unsuccessful. This can be solved with a Technology known as "Burn Proof".

1207: Raid that functions as part of the operating system on the file server A. Software implementation B. Hardware implementation C. Network implementation D. Netware implementation

A Explanation: This kind of RAID is totally depended on the operating system, this is because the server does not have any special hardware - RAID controller in the board. This kind of RAID implementation usually degrades performance because it takes many CPU cycles. A very common example of software RAID is the support for it on Windows 2000 Server, where you can create RAID 0,1 and 5 through heterogeneous disks, you can even make a RAID between one SCSI and one EIDE disk. The software implementation is hardware independent always that the disks are recognized by the Operating System.

1261: In the OSI/ISO model, at what level is SET (SECURE ELECTRONIC TRANSACTION PROTOCOL) provided? A. Application B. Network C. Presentation D. Session

A Explanation: This protocol was created by VISA and MasterCard as a common effort to make the buying process over the Internet secure through the distribution line of those companies. It is located in layer 7 of the OSI model, the application layer. SET uses a system of locks and keys along with certified account IDs for both consumers and merchants. Then, through a unique process of "encrypting" or scrambling the information exchanged between the shopper and the online store, SET ensures a payment process that is convenient, private and most of all secure.

1265: Which of the following can be used as a covert channel? A. Storage and timing. B. Storage and low bits. C. Storage and permissions. D. Storage and classification.

A Explanation: Those are the proper elements, you can use these two to achieve a covert channel. Low bits is not a term related to covert channels. Permissions are related to authentication, they do not achieve what the question wants. Also, classification is could not selected as a correct choice. Check your official CISSP documentation to see what can be used as a covert channel. "An active variation on eavesdropping is called Covert Channel eavesdropping, which consists of using a hidden unauthorized network connection to communicate unauthorized information. A Covert Storage Channel operates by writing information to storage by one process and then reading by using another process from a different security level. A Covert Timing Channel signals information to another process by modulating its own resource use to affect the response time of another." Pg. 101 Krutz: The CISSP Prep Guide: Gold Edition

284: Which of the following is the MOST secure network access control procedure to adopt when using a callback device? A. The user enters a userid and PIN, and the device calls back the telephone number that corresponds to the userid. B. The user enters a userid, PIN, and telephone number, and the device calls back the telephone number entered. C. The user enters the telephone number, and the device verifies that the number exists in its database before calling back. D. The user enters the telephone number, and the device responds with a challenge.

A Explanation: Usually a request for a username and password takes place and the NAS may hang up the call in order to call the user back at a predefined phone number. This is a security activity that is used to try and ensure that only authenticated users are given access to the network and it reverse the long distance charges back to the company...However, this security measure can be compromised if someone implements call forwarding. - Shon Harris All-in-one CISSP Certification Guide pg 463

993: Which of the following steps it NOT one of the four steps of a Business Impact Analysis (BIA)? A.) Notifying senior management B.) Gathering the needed assessment materials C.) Performing the vulnerability assessment D.) Analyzing the information compiled

A "A BIA generally takes the form of these four steps: 1.) Gathering the needed assessment materials 2.) Performing the vulnerability assessment 3.) Analyzing the information compiled 4.) Documenting the results and presenting recommendations" Pg. 383 Krutz: CISSP Prep Guide: Gold Edition.

565: Which of the following usually provides reliable, real-time information without consuming network or host resources? A.) network-based IDS B.) host-based IDS C.) application-based IDS D.) firewall-based IDS

A "A network-based IDS has little negative affect on overall network performance, and because it is deployed on a single-purpose system, it doesn't adversely affect the performance of any other computer." Pg 34 Krutz: CISSP Prep Guide: Gold Edition.

10: Which of the following defines the intent of a system security policy? A. A definition of the particular settings that have been determined to provide optimum security. B. A brief, high-level statement defining what is and is not permitted during the operation of the system. C. A definition of those items that must be excluded on the system. D. A listing of tools and applications that will be used to protect the system.

A "A system-specific policy presents the management's decisions that are closer to the actual computers, networks, applications, and data. This type of policy can provide an approved software list, which contains a list of applications that can be installed on individual workstations. This policy can describe how databases are to be protected, how computers are to be locked down, and how firewall, intrusion diction systems, and scanners are to be employed." Pg 93 Shon Harris CISSP All-In-One Certification Exam Guide

66: Qualitative loss resulting from the business interruption does not include: A.) Loss of revenue B.) Loss of competitive advantage or market share C.) Loss of public confidence and credibility D.) Public embarrassment

A "Another method of risk analysis is qualitative, which does not assign numbers and monetary valu8es to components and losses." Pg 72 Shon Harris: All-in-One CISSP Certification

417: How is polyinstantiation used to secure a multilevel database? CISSP Actualtests.com - The Power of Knowing A. It prevents low-level database users from inferring the existence of higher level data. B. It confirms that all constrained data items within the system conform to integrity specifications. C. It ensures that all mechanism in a system are responsible for enforcing the database security policy. D. Two operations at the same layer will conflict if they operate on the same data item and at least one of them is an update.

A "Polyinstantiation is the development of a detailed version of an object from another object using different values in the new object. In the database information security, this term is concerned with the same primary key for different relations at different classification levels being stored in the same database. For example, in a relational database, the same of a military unit may be classified Secret in the database and may have an identification number as the primary key. If another user at a lower classification level attempts to create a confidential entry for another military unit using the same identification number as a primary key, a rejection of this attempt would imply to the lower level user that the same identification number existed at a higher level of classification. To avoid this inference channel of information, the lower level user would be issued the same identification number for their unit and the database management system would manage this situation where the same primary key was used for different units." Pg 352-353 Krutz: The CISSP Prep Guide: Gold Edition. "Polyinstantiation occurs when to or more rows in the same table appear to have identical primary key elements but contain different data for use at differing classification levels. Polyinstantiation is often used as a defense against some types of inference attacks. For example, consider a database table containing the location of various naval ships on patrol. Normally, this database contains the exact position of each ship stored at the level with secret classification. However, on particular ship, the USS UpToNoGood, is on an undercover mission to a top-secret location. Military commanders do not want anyone to know that the ship deviated from its normal patrol. If the database administrators simply change the classification of the UpToNoGood's location to top secret, a user with secret clearance would know that something unusual was going on when they couldn't query the location of the ship. However, if polyinstantiation is used, two records could be inserted into the table. The first one, classified at the top secret level, would reflect the true location of the ship and be available only to users with the appropriate top secret security clearance. The second record, classified at the secret level, would indicate that the ship was on routine patrol and would be returned to users with a secret clearance."

790: What encryption algorithm is best suited for communication with handheld wireless devices? A.) ECC B.) RSA C.) SHA D.) RC4

A "Eliptic curves are rich mathematical structures that have shown usefulness in many different types of applications. An Elliptic Curve Cryptosystem (ECC) provides much of the same functionality that RSA provides: digital signatures, secure key distribution, and encryption. One differing factor is ECC's efficiency. Some devices have limited processing capacity, storage, power supply, and bandwidth like wireless devices and cellular telephones. With these types of devices, efficiency of resource use is very important. ECC provides encryption functionality requiring a smaller percentage of resources required by RSA and other algorithms, so it is used in these types of devices. In most cases, the longer the key length, the protection provided, but ECC can provide the same level of protection with a key size that is smaller than what RSA requires. Because longer keys require more resources to perform mathematical tasks, the smaller keys used in ECC require fewer resources of the device."

A "In order to set up and manage Sas on the Internet, a standard format called the Internet Security Association and Key Management Protocol (ISAKMP) was established. ISAKMP provides for secure key exchange and data authentication. However, ISAKMP is independent of the authentication protocols, security protocols, and encryption algorithms. Strictly speaking, a combination of three protocols is used to define key management for IPSEC. These protocols are ISAKMP, Secure Key Exchange Mechanism (SKEME) and Oakley. When combined and applied to IPSEC, these protocols are called the Internet Key Exchange (IKE) protocol." Pg. 222 Krutz: The CISSP Prep Guide: Gold Edition

752: What size is an MD5 message digest (hash)? A.) 128 bits B.) 160 bits C.) 256 bits D.) 128 bytes

A "MD4 MD4 is a one-way hash function designed by Ron Rivest. It produces 128-bit hash, or message digest, values. It is used for high-speed computation in software implementations and is optimized for microprocessors. MD5 MD5 is the newer version of MD4. It still produces a 128-bit hash, but the algorithm is more CISSP Actualtests.com - The Power of Knowing complex, which makes it harder to break. MD5 added a fourth round of operations to be performed during the hashing functions and makes several of it mathematical operations carry out more steps or more complexity to provide a higher level of security. MD2 MD2 is also a 128-bit one-way hash designed by Ron Rivest. It is not necessarily any weaker than the previously mentioned hash functions, but is much slower. SHA SHA was designed by NIST and NSA to be used with DSS. The SHA was designed to be used with digital signatures and was developed when a more secure hashing algorithm was required for federal application. SHA produces a 160-bit hash value, or message digest. This is then inputted into the DSA, which computes the signature for a message. The message digest is signed instead of the whole message because it is a much quicker process. The sender computes a 160-bit hash value, encrypts it with his private key (signs it), appends it to the message, and sends it. The receiver decrypts the value with the sender's public key, runs the same hashing function, and compares the two values. If the values are the same, the receiver can be sure that the message has not been tampered with in transit. SHA is similar to MD4. It has some extra mathematical functions and produces a 160-bit hash instead of 128-bit, which makes it more resistant to brute force attacks, including birthday attacks. HAVAL HAVAL is a variable-length one-way hash function and is the modification of MD5. It processes message blocks twice the size of those used in MD5; thus it processes blocks of 1,024 bits.

182: Access control techniques do not include which of the following choices? A.) Relevant Access Controls B.) Discretionary Access Controls C.) Mandatory Access Controls D.) Lattice Based Access Controls

A "Mandatory Access Control. The authorization of a subject's access to an object depends upon labels, which indicate the subject's clearance, and the classification or sensitivity of the object." "Rule-based access control is a type of mandatory access control because rules determine this access, rather than the identity of the subjects and objects alone." "Discretionary Access Control.The subject has authority, within certain limitations, to specify what objects are accessible." "When a user with certain limitations has the right to alter the access control to certain objects, this is termed as user-directed discretionary access control." "An identity-based access control is a type of a discretionary access control based on an individual's identity." "In some instances, a hybrid approach is used, which combines the features of user-based and identity-based discretionary access control." "Non-discretionary Access Control. A Central authority determines what subjects can have access to certain objects based on the organizational security policy." "The access controls might be based on the individuals role in the organization (role-based) or the subject's responsibilities and duties (task-based)." CISSP Actualtests.com - The Power of Knowing "[Lattice-based] In this type of control, a lattice model is applied. "Access control can be characterized as context-dependent or content dependent."

Pg 352-353 Krutz: The CISSP Prep Guide: Gold Edition. "As with aggregation, the best defense against inference attacks is to maintain constant vigilance over the permissions granted to individual users. Furthermore, intentional blurring of data may be used to prevent the inference of sensitive information." - Ed Tittle CISSP Study Guide (sybex) The other security issue is inference, which is very similar to aggregation. The inference problem happens when a subject deduces information that is restricted from data he has access to. This is seen when data at a lower security level indirectly portrays data at a higher level...This problem is usually dealt with in the development of the database by implementing content and context-dependent classification rules; this tracks the subject's query requests and restricts patterns that represent inference.

156: Which factor is critical in all systems to protect data integrity? A. Data classification B. Information ownership C. Change control D. System design CISSP Actualtests.com - The Power of Knowing

A A Integrity is dependent on confidentiality, which relies on data classification. Also Biba integrity model relies on data classification. "There are numerous countermeasures to ensure confidentiality against possible threats. These include the use of encryption, network traffic padding, strict access control, rigorous authentication procedures, data classification, and extensive personnel training. Confidentiality and integrity are dependent upon each other. Without object integrity, confidentiality cannon be maintained. Other concepts, conditions, and aspects of confidentiality include sensitivity, discretion, criticality, concealment, secrecy, privacy, seclusion, and isolation." Pg 145 Tittel: CISSP Study Guide. "Biba Integrity Model Integrity is usually characterized by the three following goals: 1.) The data is protected from modification by unauthorized users. 2.) The data is protected from unauthorized modification by authorized users. 3) The data is internally and externally consistent; the data held in a database must balance internally and correspond to the external, real world situation."

A A reference monitor is a system component that enforces access controls on an object. Therefore, the reference monitor concept is an abstract machine that mediates all access of subjects to objects -Ronald Krutz The CISSP PREP Guide (gold edition) pg 262

450: Which one of the following properties of a transaction processing system ensures that once a transaction completes successfully (commits), the update service even if there is a system failure? A. Atomicity B. Consistency C. Isolation D. Durability

A Atomicity is correct. Consistency is not a viable answer. Atomicity states that database modifications must follow an "all or nothing" rule. Each transaction is said to be "atomic." If one part of the transaction fails, the entire transaction fails. It is critical that the database management system maintain the atomic nature of transactions in spite of any DBMS, operating system or hardware failure. Consistency states that only valid data will be written to the database. If, for some reason, a transaction is executed that violates the database's consistency rules, the entire transaction will be rolled back and the database will be restored to a state consistent with those rules. On the other hand, if a transaction successfully executes, it will take the database from one state that is consistent with the rules to another state that is also consistent with the rules. Isolation requires that multiple transactions occurring at the same time not impact each other's execution. For example, if Joe issues a transaction against a database at the same time that Mary issues a different transaction, both transactions should operate on the database in an isolated manner. The database should either perform Joe's entire transaction before executing Mary's or vice-versa. This prevents Joe's transaction from reading intermediate data produced as a side effect of part of Mary's transaction that will not eventually be committed to the database. Note that the isolation property does not ensure which transaction will execute first, merely that they will not interfere with each other. Durability ensures that any transaction committed to the database will not be lost. Durability is ensured through the use of database backups and transaction logs that facilitate the restoration of committed transactions in spite of any subsequent software or hardware failures.

1003: Which one the following is the primary goal of Business Continuity Planning? A. Sustain the organization. B. Recover from a major data center outage. C. Test the ability to prevent major outages. D. Satisfy audit requirements.

1099: In what way could the use of "cookies" violate a person's privacy? A. When they are used to tie together a set of unconnected requests for web pages to cause an electronic map of where one has been. B. When they are used to keep logs of who is using an anonymizer to access a site instead of their regular userid. C. When the e-mail addresses of users that have registered to access the web site are sold to marketing firms.

A Both A and C are correct in that they are true but from a CISSP viewpoint looking into a PC the cookies CISSP Actualtests.com - The Power of Knowing show a map of where the user has been. Therefore I think A is the better choice. "Any web site that knows your identity and has cookie for you could set up procedures to exchange their data with the companies that buy advertising space from them, synchronizing the cookies they both have on your computer. This possibility means that once your identity becomes known to a single company listed in your cookies file, any of the others might know who you are every time you visit their sites. The result is that a web site about gardening that you never told your name could sell not only your name to mail-order companies, but also the fact that you spent a lot of time one Saturday night last June reading about how to fertilize roses. More disturbing scenarios along the same lines could be imagined." http://www.junkbusters.com/cookies.html

353: What is an effective countermeasure against Trojan horse attack that targets smart cards? A. Singe-access device driver architecture. B. Handprint driver architecture. C. Fingerprint driver architecture. D. All of the choices.

A CISSP Actualtests.com - The Power of Knowing Explanation: The countermeasure to prevent this attack is to use "single-access device driver" architecture. With this type of architecture, the operating system enforces that only one application can have access to the serial device (and thus the smartcard) at any given time. This prevents the attack but also lessens the convenience of the smartcard because multiple applications cannot use the services of the card at the same time. Another way to prevent the attack is by using a smartcard that enforces a "one private key usage per PIN entry" policy model. In this model, the user must enter their PIN every single time the private key is to be used and therefore the Trojan horse would not have access to the key.

246: You are comparing biometric systems. Security is the top priority. A low ________ is most important in this regard. A. FAR B. FRR C. MTBF D. ERR

A CISSP Actualtests.com - The Power of Knowing Explanation: When comparing biometric systems, a low false acceptance rate is most important when security is the priority. Whereas, a low false rejection rate is most important when convenience is the priority. All biometric implementations balance these two criteria. Some systems use very high FAR's such as 1 in 300. This means that the likelihood that the system will accept someone other than the enrolled user is 1 in 300. However, the likelihood that the system will reject the enrolled user (its FRR) is very low, giving them ease of use, but with low security. Most fingerprint systems should be able to run with FARs of 1 in 10,000 or better.

1197: IF an operating system permits executable objects to be used simultaneously by multiple users without a refresh of the objects, what security problem is most likely to exist? A. Disclosure of residual data. B. Unauthorized obtaining of a privileged execution state. C. Data leakage through covert channels. D. Denial of service through a deadly embrace.

A CISSP Actualtests.com - The Power of Knowing Explanation: This is a well known issue knew by many programmers, since the operating system is allowing the executables to be used by many users in different sessions at the same time, and there is not refreshing every certain time, there will be a disclosure of residual data. To fix this we need to get sure that objects are refreshed frequently, for added security its better an OS that does not allow the use of an executable object by many users at the same time.

The content of the database fields dictates which user can see specific information within the database tables." pg 161 Shon Harris: All-In-One CISSP Certification. Decisions will have to be made about the content, therefore increasing processing overhead.

430: SQL security issues include which of the following? A.) The granularity of authorizations B.) The size of databases C.) The complexity of key structures D.) The number of candidate key elements

A Developed by IBM, SQL is a standard data manipulation and relational database definition language. The SQL Data Definition Language creates and deletes views and relations (tables). SQL commands include Select, Update, Delete, Insert, Grant, and Revoke. The latter two commands are used in access control to grant and revoke privileges to resources. Usually, the owner of an object can withhold or transfer GRANT privileges to an object to another subject. If the owner intentionally does not transfer the GRANT privileges, however, which are relative to an object to the individual A, A cannot pass on the GRANT privileges to another subject. In some instances, however, this security control can be circumvented. For example, if A copies the object, A essentially becomes the owner of that object and thus can transfer the GRANT privileges to another user, such as user B. SQL security issues include the granularity of authorization and the number of different ways you can execute the same query. Pg. 63 Krutz: The CISSP Prep Guide: Gold Edition.

1043: Under the standard of due care, failure to achieve the minimum standards would be CISSP Actualtests.com - The Power of Knowing considered A. Negligent B. Unethical C. Abusive D. Illegal

795: Why do vendors publish MD5 hash values when they provide software patches for their customers to download from the Internet? A. Recipients can verify the software's integrity after downloading. B. Recipients can confirm the authenticity of the site from which they are downloading the patch. C. Recipients can request future updates to the software by using the assigned hash value. D. Recipients need the hash value to successfully activate the new software. CISSP Actualtests.com - The Power of Knowing

A If the two values are different, Maureen knows that the message was altered, either intentionally or unintentionally, and she discards the message...As stated in an earlier section, the goal of using a one-way hash function is to provide a fingerprint of the message. MD5 is the newer version of MD4. IT still produces a 128-bit hash, but the algorithm is a bit more complex to make it harder to break than MD4. The MD5 added a fourth round of operations to be performed during the hash functions and makes several of its mathematical operations carry steps or more complexity to provide a higher level of security . - Shon Harris All-in-one CISSP Certification Guide pg 182-185

727: A network of five nodes is using symmetrical keys to securely transmit data. How many new keys are required to re-establish secure communications to all nodes in the event there is a key compromise? A. 5 B. 10 C. 20 D. 25

A In a typical vpn using secret keys there would be one key at central office and the same key provided for each telecommuter, in this case 4. If the key was compromised, all 5 keys would have to be changed. "Secret key cryptography is the type of encryption that is familiar to most people. In this type of cryptography, the sender and receiver both know a secret key. The sender encrypts the plaintext message with the secret key, and the receiver decrypts the message with the same secret key." -Ronald Krutz The CISSP PREP Guide (gold edition) pg 194

3: Which one of the following is an important characteristic of an information security policy? A. Identifies major functional areas of information. B. Quantifies the effect of the loss of the information. C. Requires the identification of information owners. D. Lists applications that support the business function.

A Information security policies area high-level plans that describe the goals of the procedures. Policies are not guidelines or standards, nor are they procedures or controls. Policies describe security in general terms, not specifics. They provide the blueprints for an overall security program just as a specification defines your next product - Roberta Bragg CISSP Certification Training Guide (que) pg 206 CISSP Actualtests.com - The Power of Knowing

812: Which one of the following describes Kerchoff's Assumption for cryptoanalytic attack? A. Key is secret; algorithm is Known B. Key is known; algorithm is Known C. Key is secret; algorithm is secret D. Key is known; algorithm is secret

A Kerhkoff's laws were intended to formalize the real situation of ciphers in the field. Basically, the more we use any particular cipher system, the more likely it is that it will "escape" into enemy hands. So we start out assuming that our opponents know "all the details" of the cipher system, except the key. http://www.ciphersbyritter.com/NEWS4/LIMCRYPT.HTM

1429: Macro viruses infect what type of files. A. Microsoft office files B. Mail servers C. E-mail messages D. Web browsers E. Linux Kernel files

458: By far, the largest security exposure in application system development relates to A. Maintenance and debugging hooks. B. Deliberate compromise. C. Change control. D. Errors and lock of training

A Maintenance hook - instructions within a program's code that enable the developer or maintainer to enter the program without having to go through the usual access control and authentication processes. They should be removed from the code before being released for production; otherwise, they can cause serious security risks. They are also referred to as trapdoors. - Shon Harris All-in-one CISSP Certification Guide pg 933

440: Which one of the following control steps is usually NOT performed in data warehousing applications? A. Monitor summary tables for regular use. B. Control meta data from being used interactively. C. Monitor the data purging plan. D. Reconcile data moved between the operations environment and data warehouse.

A Not B: It is important to control meta data from being used interactively by unauthorized users. "Data warehouses and data mining are significant to security professionals for two reasons. First, as previously mentioned, data warehouses contain large amounts of potentially sensitive information vulnerable to aggregation and inference attacks, and security practitioners must ensure that adequate access controls and other security measures are in place to safeguard this data." Pg 192 Tittel: CISSP Study Guide Not C: "The data in the data warehouse must be maintained to ensure that it is timely and valid. The term data scrubbing refers to maintenance of the data warehouse by deleting information that is unreliable or no longer relevant." Pg 358-359 Krutz: The CISSP Prep Guide: Gold Edition Not D: "To create a data warehouse, data is taken from an operational database, redundancies are removed, and the data is "cleaned up" in general." Pg 358 Krutz: The CISSP Prep Guide: Gold Edition

808: What is the purpose of certification path validation? A. Checks the legitimacy of the certificates in the certification path. B. Checks that all certificates in the certification path refer to same certification practice statement. C. Checks that no revoked certificates exist outside the certification path. D. Checks that the names in the certification path are the same.

A Not C. Revoked certificates are not checked outside the certification path. "A Transaction with Digital Certificates 1.) Subscribing entity sends Digital Certificate Application to Certificate Authority. 2.) Certificate Authority issues Signed Digital Certificate to Subscribing Entity. 3.) Certificate Authority sends Certificate Transaction to Repository. 4.) Subscribing Entity Signs and sends to Party Transacting with Subscriber. 5.) Party Transacting with Subscriber queries Repository to verify Subscribers Public Key. 6.) Repository responds to Party Transacting with Subscriber the verification request." Pg. 214 Krutz: The CISSP Prep Guide: Gold Edition. "John needs to obtain a digital certificate for himself so that he can participate in a PKI, so he makes a request to the R A. The RA requests certain identification from John, like a copy of his driver's licens, his phone number, address, and other identification information. Once the RA receives the required informoration from John and verifies it, the RA sends his certificate request to the C A. The CA creates a certificate with John's public key and identify information embedded. (The private/public key pair is either generated by the CA or on John's machine, which depends on the systems' configurations. If it is created at the CA, his private key needs to be sent to him by secure means. In most cases the user generates this pair and sends in his public key during the registration process.) Now John is registered and can participate in PKI. John decides he wants to communicate with Diane, so he requests Diane's public key from a public directory. The directory, sometimes called a repository, sends Diane's public key, and John uses this to encrypt a session key that will be used to encrypt their messages. John sends the encrypted session key to Diane. Jon then sends his certificate, containing his public key, to CISSP Actualtests.com - The Power of Knowing Diane. When Diane receives John's certificate, her browser looks to see if it trusts the CA that digitally signed this certificate. Diane's browser trusts this CA, and she makes a reques to the CA to see if this certificate is still valid. The CA responds that the certificate is valid, so Diane decrypts the session key with her private key. Now they can both communicate using encryption."

A Original Answer was C. This is wrong in my view as the original answer confused ITSEC with the CC per the following The Common criteria terminology for the degree of examination of the product to be tested is the Evaluation Assurance level (EAL). EALs range from EA1 (functional testing to EA7 (detailed testing and formal design verification). -Ronald Krutz The CISSP PREP Guide (gold edition) pg 266-267 Note that Shon Harris All-in-one CISSP Certification Guide uses EAL (not just EA). EALs are combinations of assurance components. They also can be conveniently compared to TSCEC and ITSEC. Like these security evaluation criteria, EALs are scaled with from EAL1 through EAL7. Other EALs exist, but EAL 7 is the highest with international recognition. - Roberta Bragg Cissp Certification Training Guide (que) pg 368 ITSEC separately evaluates functionality and assurance, and it includes 10 functionality classes (f), eight assurance levels (q), seven levels of correctness (e), and eight basic security functions in its criteria. ). -Ronald Krutz The CISSP PREP Guide (gold edition) pg 266

B. a Security Target (ST). C. an evaluation Assurance Level (EAL). D. a Security Functionality Component Catalog (SFCC).

A Protection Profiles: The Common Criteria uses protection profiles to evaluate products. The protection profile contains the set of security requirements, their meaning and reasoning, and the corresponding EAL rating. The profile describes the environmental assumptions, the objectives, and functional and assurance level expectations. Each relevant threat is listed along with how it is to be controlled by specific objectives. It also justifies the assurance level and requirements for the strength of each protection mechanism. The protection profile provides a means for the consumer, or others, to identify specific security needs ;p this is the security problems to be conquered. EAL: An evaluation is carried out on a product and is assigned an evaluation assurance level (EAL) The thoroughness and stringent testing increases in detailed-oriented tasks as the levels increase. The Common Criteria has seven aassurance levels. The ranges go from EAL1, where CISSP Actualtests.com - The Power of Knowing the functionality testing takes place, to EAL7,where thorough testing is performed and the system is verified. All-In-One CISSP Certification Exam Guide by Shon Harris pg. 262 Note: "The Common Criteria defines a Protection Profile (PP), which is an implementation-independent specification of the security requirements and protections of a product that could be built. The Common Criteria terminology for the degree of examination of the product to be tested is the Evaluation Assurance Level (EAL). EALs range from EA1 (functional testing) to EA7 (detailed testing and formal design verification). The Common Criteria TOE [target of evaluation] refers to the product to be tested. A Security Target (ST) is a listing of the security claims for a particular IT security product." -Ronald Krutz The CISSP PREP Guide (gold edition) pg 266-267

930: In which way does a Secure Socket Layer (SSL) server prevent a "man-in-the-middle" attack? A. It uses signed certificates to authenticate the server's public key. B. A 128 bit value is used during the handshake protocol that is unique to the connection. C. It uses only 40 bits of secret key within a 128 bit key length. D. Every message sent by the SSL includes a sequence number within the message contents.

A Secure Sockets Layer (SSL). An encryption technology that is used to provide secure transactions such as the exchange of credit card numbers. SSL is a socket layer security protocol and is a two-layered protocol that contains the SSL Record Protocol and the SSL Handshake Protocol. Similiar to SSH, SSL uses symmetric encryption for private connections and CISSP Actualtests.com - The Power of Knowing asymmetric or public key cryptography (certificates) for peer authentication. It also uses a Message Authentication Code for message integrity checking. Krutz: The CISSP Prep Guide pg. 89. It prevents a man in the middle attack by confirming that you are authenticating with the server desired prior entering your user name and password. If the server was not authenticated, a man-in-the-middle could retrieve the username and password then use it to login. The SSL protocol has been known to be vulnerable to some man-in-the-middle attacks. The attacker injects herself right at the beginning of the authentication phase so that she obtains both parties' keys. This enables her to decrypt and view messages that were not intended for her. Using digital signatures during the session-key exchange can circumvent the man-in-the-middle attack. If using kerberos, when Lance and Tanya obtain each other's public keys from the KDC, the public keys are signed by the KDC. Because Tanya and Lanace have the public key of the KDC, they both can decrypt and verify the signature on each other's public key and be sure that it came from the KDC itself. Because David does not have the private key of the KDC, he cannot substitute his pubic key during this type of transmission. Shon Harris All-In-One CISSP Certification pg. 579. One of the most important pieces a PKI is its public key certificate. A certificate is the mechanism used to associate a public key with a collection of components sufficient to uniquely authenticate the claimed owner. Shon Harris All-In-One CISSP Certification pg. 540.

137: The Trusted Computer Security Evaluation Criteria (TBSEC) provides A. a basis for assessing the effectiveness of security controls built into automatic data-processing system products B. a system analysis and penetration technique where specifications and document for the system are analyzed. C. a formal static transition model of computer security policy that describes a set of access control rules. D. a means of restricting access to objects based on the identity of subjects and groups to which they belong.

A TBSEC provides guidelines to be used with evaluating a security product. The TBSEC guidelines address basic security functionality and allow evaluators to measure and rate the functionality of a system and how trustworthy it is. Functionality and assurance are combined and not separated, as in criteria developed later. TCSEC guidelines can be used for evaluating vendor products or by vendors to design necessary functionality into new products. CISSP Study Guide by Tittel pg. 413.

160: What can be defined as a formal security model for the integrity of subjects and objects in a system? A. Biba B. Bell LaPadulaLattice C. Lattice D. Info Flow

A The Handbook of Information System Management, 1999 Edition, ISBN: 0849399742 presents the following definition: In studying the two properties of the Bell-LaPadula model, Biba discovered a plausible notion of integrity, which he defined as prevention of unauthorized modification. The resulting Biba integrity model states that maintenance of integrity requires that data not flow from a receptacle of given integrity to a receptacle of higher integrity. For example, if a process can write above its security level, trustworthy data could be contaminated by the addition of less trustworthy data. SANS glossary at http://www.sans.org/newlook/resources/glossary.htm define it as: Formal security model for the integrity of subjects and objects in a system.

1445: ____________ is the first step of access control. A. Identification B. Authorization C. Validation D. Interrogation E. Accountability logging

A The first step in the access control process is identifying who the subject is.

803: Digital signature users register their public keys with a certification authority, which distributes a certificate containing the user's public key and digital signature of the certification authority. In creating the certificate, the user's public key and the validity period are combined with what other information before computing the digital signature? A. Certificate issuer and the Digital Signature Algorithm identifier B. User's private key and the identifier of the master key code C. Name of secure channel and the identifier of the protocol type D. Key authorization and identifier of key distribution center

A The key word is 'In create the certificate.." Certificates Certificates that conform to X.509 contain the following data: Version of X.509 to which the certificate conforms; Serial number (from the certificate cerator); Signature algorithm identifier (specifies the technique used by the certified authority to digitally sign the contents of the certificate); Issuer name (identification of the certificate authority that issues the certificate) Validity period (specifies the dates and times - a starting date and time and an ending date and time - during which the certificate is validated); Subject's name (contains the distinguished name, or DN, of the entity that owns the public key contained in teh certificate); Subject's public key (the meat of the certificate - the actual public key of the certificate owner used to setup secure communications) pg 343-344 CISSP Study Guide byTittel

761: When block chaining cryptography is used, what type of code is calculated and appended to the data to ensure authenticity? A. Message authentication code. B. Ciphertext authentication code C. Cyclic redundancy check D. Electronic digital signature

A The original Answer was B. This is incorrect as cipthertext is the result not an authentication code. "If meaningful plaintext is not automatically recognizable, a message authentication code (MAC) can be computed and appended to the message. The computation is a function of the entire message and a secret key; it is practically important to find another message with the same authenticator. The receiver checks the authenticity of the message by computing the MAC using the same secret key and then verifying that the computed value is the same as the one transmitted with the message. A MAC can be used to provide authenticity for unencrypted messages as well as for encrypted ones. The National Institute of Standards and Technology (NIST) has adopted a standard for computing a MAC. (It is found in Computer Data Authentication, Federal Information Processing Standards Publication (FIPS PUB) 113.)" http://www.cccure.org/Documents/HISM/637-639.html from the Handbook of Information Security Management by Micki Krause

622: Which of the following are functions that are compatible in a properly segregated CISSP Actualtests.com - The Power of Knowing environment? A.) Data entry and job scheduling B.) Database administration and systems security C.) Systems analyst and application programming D.) Security administration and systems programming

A The two most similar jobs are Data Entry and Job Scheduling, so they need not be segregated. Administrative Management: Administratative management is a very important piece of operational security. One aspect of administrative management is dealing with personnel issues. This includes separation of duties and job rotation. The objective of separation of duties is to ensure that one person acting alone cannot compromise the company's security in any way. High-risk activities should be broken up into different parts and distributed to different individuals. This way the company does not need to put a dangerously high level of trust on certain individuals and if fraud were to take place, collusion would need to be committed, meaning more than one person would have to be involved in the fraudulent activity. Separation of duties also helps to prevent many different types of mistakes that can take place if one person is performing a task from the beginning to the end. For instance, a programmer should not be the one to test her own code. A different person with a different job and agenda should perform functionality and integrity testing on the programmer's code because the programmer may have a focused view of what the program is supposed to accomplish and only test certain functions, input values, and in certain environments. Another example of separation of duties is the difference between the functions of a computer operator versus the functions of a system administrator. There must be clear cut lines drawn between system administrator duties and computer operator duties. This will vary from environment to environment and will depend on the level of security required within the environment. The system administrators usually have responsibility of performing backups and recovery procedures, setting permissions, adding and removing users, setting user clearance, and developing user profiles. The computer operator on the other hand, may be allowed to install software, set an initial password, alter desktop configurations, and modify certain system parameters. The computer operator should not be able to modify her own security profile, add and remove users globally, or set user security clearance. This would breach the concept of separation of duties.

A There are three main performance issues in biometrics. These measures are as follows: False Rejection Rate (FRR) or Type 1 Error. The percentage of valid subjects that are falsely rejected. False Acceptance Rate (FAR) or Type 2 Error. The percentage of invalid subjects that are falsely accepted. Crossover Error Rate (CER). The percent in which the False Rejection Rate equals the False Acceptance Rate. pg 38 Krutz: The CISSP Prep Guide

8: Why must senior management endorse a security policy? A. So that they will accept ownership for security within the organization. B. So that employees will follow the policy directives. C. So that external bodies will recognize the organizations commitment to security. D. So that they can be held legally accountable.

A This really does not a reference as it should be known. Upper management is legally accountable (up to 290 million fine). External organizations answer is not really to pertinent (however it stated that other organizations will respect a BCP and disaster recover plan). Employees need to be bound to the policy regardless of who signs it but it gives validity. Ownership is the correct answer in this statement. However, here is a reference. "Fundamentally important to any security program's success us the senior management's high-level statement of commitment to the information security policy process and a senior management's understanding of how important security controls and protections are to the enterprise's continuity. Senior management must be aware of the importance of security implementation to preserve the organization's viability (and for their own 'due care' protection) and must publicly support that process throughout the enterprise." -Ronald Krutz The CISSP PREP Guide (gold edition) pg 13

1425: ________ deemed proprietary to a company and can be information that provides a competitive edge. A. Trade secrets are B. Copyrights are C. Restricted information is D. Information marked strictly private is

A Trade secrets are deemed proprietary to a company and can be information that provides a competitive edge. This information is protected as long as the owner takes the necessary security actions.

673: The basic Electronic Access Control (EAC) components required for access doors are an electromagnetic lock, A. A credential reader, and a door closed sensor. B. A card reader, and a door open sensor. C. A biometric reader, and a door open sensor. D. A card reader, and door motion detector.

A We have not been able to find any reference to this question really. So we are going with A "In addition to smart and dumb cards, proximity readers can be used to control physical access. A proximity reader can be passive device, a field-powered device, or a transponder." - Ed Tittle CISSP Study Guide (sybex) pg 650

495: Removing unnecessary processes, segregating inter-process communications, and reducing executing privileges to increase system security is commonly called A. Hardening B. Segmenting C. Aggregating D. Kerneling CISSP Actualtests.com - The Power of Knowing

A What is hardening? Naturally, there is more than one definition, but in general, one tightens control using policies which affect authorization, authentication and permissions. Nothing happens by default. You only give out permission after thinking about it, something like "deny all" to everyone, then "allow" with justification. Shut off everything, then only turn on that which must be turned on. It is not unlike locking every single door, window and access point in your house, then unlocking only those that need to be. It is quite common for users to take all the defaults when their new system gets turned on making for instant vulnerability. A major problem is trying to figure out where all those details are that need to be turned off, without making the system unusable.

544: What are the primary goals of intrusion detection systems? (Select all that apply.) CISSP Actualtests.com - The Power of Knowing A. Accountability B. Availability C. Response D. All of the choices

A, C Explanation: Although there are many goals associated with security mechanisms in general, there are two overarching goals usually stated for intrusion detection systems. Accountability is the capability to link a given activity or event back to the party responsible for initiating it. This is essential in cases where one wishes to bring criminal charges against an attacker. The goal statement associated with accountability is: "I can deal with security attacks that occur on my systems as long as I know who did it (and where to find them.)" Accountability is difficult in TCP/IP networks, where the protocols allow attackers to forge the identity of source addresses or other source identifiers. It is also extremely difficult to enforce accountability in any system that employs weak identification and authentication mechanisms. Response is the capability to recognize a given activity or event as an attack and then taking action to block or otherwise affect its ultimate goal. The goal statement associated with response is "I don't care who attacks my system as long as I can recognize that the attack is taking place and block it." Note that the requirements of detection are quite different for response than for accountability.

B CISSP Actualtests.com - The Power of Knowing Explanation: This kind of an attack involves altering the raw data just before it is processed by a computer and then changing it back after the processing is completed. This kind of attack was used in the past to make what is stated in the question, steal small quantities of money and transfer them to the attackers account. See "Data deddling crimes" on the Web. The most correct answer is 'Salami', but since that is not an option the most correct answer is data diddling. "A salami attack is committing several small crimes with the hope that the overall larger crime will go unnoticed. ....An example would be if an employee altered a banking software program to subtract 5 cents from each of the bank's customers' accounts once a month and moved this amount to the employee's bank account. If this happened to all of the bank's 50,000 customer accounts, the intruder could make up to $ 30,000 a year. Data diddling refers to the alteration of existing data. Many times this modification happens before it is entered into an application or as soon as it completes processing and is outputted from an application. There was an incident in 1997, in Maryland, where a Taco Bell employee was sentenced to ten years in jail because he reprogrammed the drive-up window cash register to ring up ever 42.99 order as one penny. He collected the full amount from the customer, put the penny in the till, and pocketed the other $2.98. He made $3600 before his arrest."

B Explanation: Discretionary access controls can extend beyond limiting which subjects can gain what CISSP Actualtests.com - The Power of Knowing type of access to which objects. Administrators can limit access to certain times of day or days of the week. Typically, the period during which access would be permitted is 9 a.m. to 5 p.m. Monday through Friday. Such a limitation is designed to ensure that access takes place only when supervisory personnel are present, to discourage unauthorized use of data. Further, subjects' rights to access might be suspended when they are on vacation or leave of absence. When subjects leave an organization altogether, their rights must be terminated rather than merely suspended.

314: CISSP Actualtests.com - The Power of Knowing Which of the following will you consider as most secure? A. Password B. One time password C. Login phrase D. Login ID

80: To ensure least privilege requires that __________ is identified. A. what the users privilege owns B. what the users job is C. what the users cost is CISSP Actualtests.com - The Power of Knowing D. what the users group is

B Explanation: Ensuring least privilege requires identifying what the user's job is, determining the minimum set of privileges required to perform that job, and restricting the user to a domain with those privileges and nothing more. By denying to subjects transactions that are not necessary for the performance of their duties, those denied privileges couldn't be used to circumvent the organizational security policy. Although the concept of least privilege currently exists within the context of the TCSEC, requirements restrict those privileges of the system administrator. Through the use of RBAC, enforced minimum privileges for general system users can be easily achieved.

81: The concept of least privilege currently exists within the context of: A. ISO B. TCSEC C. OSI D. IEFT

This makes the fingerprint the most reliable kind of personal identification because it cannot be forgotten, misplaced, or stolen. Fingerprint authorization is potentially the most affordable and convenient method of verifying a person's identity.

178: The Lattice Based Access Control model was developed to deal mainly with ___________ in computer systems. A. Access control B. Information flow C. Message routes D. Encryption

B Explanation: Information flow is clearly central to confidentiality but to some extent it also applies to integrity. The basic work in this area was done around 1970 and was driven mostly by the defense sector. Information flow in computer systems is concerned with flow from one security class (also called security label) to another. These controls are applied to objects. An object is a container of information, and an object can be a directory or file.

179: In the Lattice Based Access Control model, controls are applied to: A. Scripts B. Objects C. Models D. Factors

254: Which of the following offers greater accuracy then the others? A. Facial recognition B. Iris scanning C. Finger scanning D. Voice recognition

385: You may describe MAC as: A. Opportunistic B. Prohibitive C. None of the choices. D. Permissive CISSP Actualtests.com - The Power of Knowing

B Explanation: It is important to note that mandatory controls are prohibitive (i.e., all that is not expressly permitted is forbidden), not permissive. Only within that context do discretionary controls operate, prohibiting still more access with the same exclusionary principle. In this type of control system decisions are based on privilege (clearance) of subject (user) and sensitivity (classification) of object (file). It requires labeling.

386: Under MAC, which of the following is true? A. All that is expressly permitted is forbidden. B. All that is not expressly permitted is forbidden. C. All that is not expressly permitted is not forbidden. D. None of the choices.

393: Under the MAC control system, what is required? A. Performance monitoring B. Labeling C. Sensing D. None of the choices

B Explanation: Limitations of the BLP model: Have no policies for changing access data control Intended for systems with static security levels Contains covert channels: a low subject can detect the existence of a high object when it is denied access. Sometimes it is enough to hide the content of an abject; also their existence may have to be hidden. Restricted to confidentiality

383: Under MAC, who can change the category of a resource? A. All users. B. Administrators only. C. All managers. D. None of the choices.

B Explanation: MAC is defined as follows in the Handbook of Information Security Management: With mandatory controls, only administrators and not owners of resources may make decisions that bear on or derive from policy. Only an administrator may change the category of a resource, and no one may grant a right of access that is explicitly forbidden in the access control policy.

561: Misuse detectors analyze system activity and identify patterns. The patterns corresponding to know attacks are called: A. Attachments B. Signatures C. Strings D. Identifications

B Explanation: Misuse detectors analyze system activity, looking for events or sets of events that match a predefined pattern of events that describe a known attack. As the patterns corresponding to known attacks are called signatures, misuse detection is sometimes called "signature-based detection." The most common form of misuse detection used in commercial products specifies each pattern of events corresponding to an attack as a separate signature. However, there are more sophisticated approaches to doing misuse detection (called "state-based" analysis techniques) that can leverage a single signature to detect groups of attacks.

321: Routing password can be restricted by the use of: A. Password age B. Password history C. Complex password D. All of the choices

B Explanation: Passwords must be changed at least once every 60 days (depending on your environment). Password aging or expiration must be enforced on all systems. Upon password expiration, if the password is not changed, only three grace logins must be allowed then the account must be disable until reset by an administrator or the help desk. Password reuse is not allowed (rotating passwords).

318: Which of the following are the correct guidelines of password deployment? A. Passwords must be masked. B. All of the choices. C. Password must have a minimum of 8 characters. D. Password must contain a mix of both alphabetic and non-alphabetic characters.

646: Preventive Technical Controls are usually built: CISSP Actualtests.com - The Power of Knowing A. By using MD5. B. Into an operating system. C. By security officer. D. By security administrator.

B Explanation: Preventive Technical Controls are the technical ways of restricting who or what can access system resources and what type of access is permitted. Its purpose is to protect the OS and other systems from unauthorized modification or manipulation. It is usually built into an operating system, or it can be a part of an application or program, or an add-on security package, or special components to regulate communication between computers. It also protects the integrity and availability by limiting the number of users and/or processes. These controls also protect confidential information from being disclosed to unauthorized persons.

404: Role based access control is attracting increasing attention particularly for what applications? A. Scientific B. Commercial C. Security D. Technical

B. It allows you to specify and enforce enterprise-specific security policies in a way that maps to your organizations structure. C. It allows you to specify and enforce enterprise-specific security policies in a way that maps to your ticketing system. D. It allows you to specify and enforce enterprise-specific security policies in a way that maps to your ACL.

B Explanation: Role based access control (RBAC) is an alternative to traditional discretionary (DAC) and mandatory access control (MAC) policies. The principle motivation behind RBAC is CISSP Actualtests.com - The Power of Knowing the desire to specify and enforce enterprise-specific security policies in a way that maps naturally to an organization's structure. Traditionally, managing security has required mapping an organization's security policy to a relatively low-level set of controls, typically access control lists.

406: DAC and MAC policies can be effectively replaced by: A. Rule based access control. B. Role based access control. C. Server based access control. D. Token based access control

B Explanation: Role based access control (RBAC) is an alternative to traditional discretionary (DAC) and mandatory access control (MAC) policies. The principle motivation behind RBAC is the desire to specify and enforce enterprise-specific security policies in a way that maps naturally to an organization's structure. Traditionally, managing security has required mapping an organization's security policy to a relatively low-level set of controls, typically access control lists.

201: A firewall can be classified as a: A. Directory based access control. B. Rule based access control. C. Lattice based access control. D. ID based access control.

B Explanation: Rule based access control is based on a specific profile for each user. Information can be easily changed for only one user but this scheme may become a burden in a very large environment. A rule-based access control unit will intercept every request to the server and compare the source specific access conditions with the rights of the user in order to make an access decision. A good example could be a firewall. Here a set of rules defined by the network administrator is recorded in a file. Every time a connection is attempted (incoming or outgoing), the firewall software checks the rules file to see if the connection is allowed. If it is not, the firewall closes the connection.

262: DSV as an identification method check against users: A. Fingerprints B. Signature C. Keystrokes D. Facial expression

B Explanation: Signature identification, also known as Dynamic Signature Verification (DSV), is another natural fit in the world of biometrics since identification through one's signature occurs during many everyday transactions. Any process or transaction that requires an individual's signature is a prime contender for signature identification.

481: In Unix, which file is required for you to set up an environment such that every used on the other host is a trusted user that can log into this host without authentication? A. /etc/shadow B. /etc/host.equiv C. /etc/passwd D. None of the choices.

B Explanation: The /etc/hosts.equiv file is saying that every user on the other host is a trusted user and allowed to log into this host without authentication (i.e. NO PASSWORD). The only thing that must exist for a user to log in to this system is an /etc/passwd entry by the same login name the user is currently using. In other words, if there is a user trying to log into this system whose login name is "bhope", then there must be a "bhope" listed in the /etc/passwd file.

175: With the Lattice Based Access Control model, a security class is also called a: A. Control factor B. Security label C. Mandatory number D. Serial ID CISSP Actualtests.com - The Power of Knowing

B Explanation: The Lattice Based Access Control model was developed to deal mainly with information flow in computer systems. Information flow is clearly central to confidentiality but to some extent it also applies to integrity. The basic work in this area was done around 1970 and was driven mostly by the defense sector. Information flow in computer systems is concerned with flow from one security class (also called security label) to another. These controls are applied to objects. An object is a container of information, and an object can be a directory or file.

269: What is typically used to illustrate the comparative strengths and weaknesses of each biometric technology? A. Decipher Chart B. Zephyr Chart C. Cipher Chart D. Zapper Chart

B Explanation: There are two types of eye scan in use today for authentication purposes: retinal scans and iris scans. Retinal Scan technology maps the capillary pattern of the retina, a thin (1/50th inch) nerve on the back of the eye. To enroll, a minimum of five scans is required, which takes 45 seconds. The subject must keep his head and eye motionless within 1/2" of the device, focusing on a small rotating point of green light. 320 - 400 points of reference are captured and stored in a 35-byte field, ensuring the measure is accurate with a negligible false rejection rate. This compares to 30-70 points of reference for a finger scan. Unfortunately a retinal scan is considerably more intrusive than an iris scans and many people are hesitant to use the device [Retina-scan]. In addition a significant number of people may be unable to perform a successful enrolment, and there exist degenerative diseases of the retina that alter the scan results over time. Despite these disadvantages, there are several successful implementations of this technology [Retina-scan].

253: Which of the following eye scan methods is considered to be more intrusive? A. Iris scans B. Retinal scans CISSP Actualtests.com - The Power of Knowing C. Body scans D. Reflective scans

1317: Computer crime is generally made possible by which of the following? A. The perpetrator obtaining training & special knowledge. B. Victim carelessness. C. Collusion with others in information processing D. System design flaws.

B Explanation: This is a real problem, nobody thinks that can be victim of a computer crime until it is. There is a big problem relating to the people thinking about this kind of attacks. Computer crimes can be very important and can make great damage to enterprises. Computer Crime will decrease once people begin to think about the Risks and begin to protect their systems from the most common attacks. CISSP Actualtests.com - The Power of Knowing

161: The Clark Wilson model has its emphasis on: A. Security B. Integrity C. Accountability D. Confidentiality CISSP Actualtests.com - The Power of Knowing

B Explanation: This model attempts to capture security requirements of commercial applications. 'Military' and 'Commercial' are shorthand for different ways of using computers. This model has emphasis on integrity: Internal consistency: properties of the internal state of a system External consistency: relation of the internal state of a system to the outside world

588: How often should logging be run? A. Once every week. B. Always C. Once a day. D. During maintenance.

B Explanation: Usually logging is done 24 hours per day, 7 days per week, on all available systems and CISSP Actualtests.com - The Power of Knowing services except during the maintenance window where some of the systems and services may not be available while maintenance is being performed.

52: What tool do you use to determine whether a host is vulnerable to known attacks? A. Padded Cells B. Vulnerability analysis C. Honey Pots D. IDS

B Explanation: Vulnerability analysis (also known as vulnerability assessment) tools test to determine whether a network or host is vulnerable to known attacks. Vulnerability assessment represents a special case of the intrusion detection process. The information sources used are system state attributes and outcomes of attempted attacks. The information sources are collected by a part of the assessment engine. The timing of analysis is interval-based or batch-mode, and the type of analysis is misuse detection. This means that vulnerability assessment systems are essentially batch mode misuse detectors that operate on system state information and results of specified test routines.

197: What is an access control model? A. A formal description of access control ID specification. B. A formal description of security policy. C. A formal description of a sensibility label. D. None of the choices.

B Explanation: What is an access control model? It is a formal description of a security policy. What CISSP Actualtests.com - The Power of Knowing is a security policy? A security policy captures the security requirements of an enterprise or describes the steps that have to be taken to achieve security. Security models are used in security evaluation, sometimes as proofs of security.

Provide a clear understanding of potential risk and exposure. C. Provide a forum for disclosing exposure and risk analysis. D. Provide a forum to communicate user responsibilities. CISSP Actualtests.com - The Power of Knowing

B Explanation: When the Security Officer is addressing Senior Management, the focus would not be on user responsibilities, it would be on making sure the Senior Management have a clear understanding of the risk and potential liability is Not D: Item D would be correct in a situation where Senior Management is addressing organizational staff.

142: According to the Orange Book, which security level is the first to require a system to protect against covert timing channels? A.) A1 B.) B3 C.) B2 D.) B1

B Explanation: A B2 system mustmeet all the requirement of a B1 system and support hierarchical devices labels, trusted path communications between the user and the system, and covert channel analysis. Exam Cram 2pg 103 and ALL-IN-ONE CISSP Third Edition by Shon Harris pg 304. The key to this question is knowingthe difference between various system ratings and keeping in mind a higher ratedsystem have all of the same security implementations as a lower rated system. In this case both B3 and A1 systems supportcovert channelanalysis, but it isimplementedfor B2 systems.

1337: CISSP Actualtests.com - The Power of Knowing Which of the following best describes the purpose of debugging programs? A. To generate random data that can be used to test programs before implementing them B. To ensure that program coding flaws are detected and corrected. C. To protect, during the programming phase, valid changes from being overwritten by other changes. D. To compare source code versions before transferring to the test environment.

B Explanation: A bug is a coding error in a computer program. The process of finding bugs before program final users is called debugging. Debugging starts after the code is first written and continues in successive stage as code is combined with other units of programming to form a software product, such as an operating system or application. The main reason to debug is to detect and correct errors in the program.

1233: The most prevalent cause of computer center fires is which of the following? A. AC equipment CISSP Actualtests.com - The Power of Knowing B. Electrical distribution systems. C. Heating systems D. Natural causes

B Explanation: According to static's, this is the greatest cause, Electrical distribution systems, specially those not installed through standards are very prone to fail and make fire inside places. AC equipment its not very prone to make fire. Natural causes it's a possibility but is definitively not the most prevalent cause. Heating systems are a very rare case of Fire beginners.

1210: Non-Discretionary Access Control. A central authority determines what subjects can have access to certain objects based on the organizational security policy. The access controls may be based on? A. The societies role in the organization. B. The individual's role in the organization. C. The group-dynamics as they relate to the individual's role in the organization. D. The group-dynamics as they relate to the master-slave role in the organization.

B Explanation: An access control model defines a computer and/or network system's rules for user access to information resources. Access control models provide confidentiality, integrity and also provide accountability through audit trails. An audit trail documents the access of an object by a subject with a record of what operations were performed. Operations include: read, write, execute and own. Non-Discretionary Access Control is usually role-based, centrally administered with authorization decisions based on the roles individuals have within an organization (e.g. bank teller, loan officer, etc. in a banking model). A system's security administrator grants and/or revokes system privileges based on a user's role. This model works well for corporations with a large turnover of personnel.

1255: Which of the following best corresponds to the type of memory addressing where the address location that is specified in the program instruction contains the address of the final desired location? A. Direct addressing B. Indirect addressing C. Indexed addressing D. Program addressing

B Explanation: An addressing mode found in many processors' instruction sets where the instruction contains the address of a memory location which contains the address of the operand (the "effective address") or specifies a register which contains the effective address. Indirect addressing is often combined with pre- or post- increment or decrement addressing, allowing the address of the operand to be increased or decreased by one (or some specified number) either before or after using it.

1158: A programmer creates a virus producing tool in order to test the performance of a new virus diction product. A. This is ethical because it was created to test and enhance the performance of a virus protection tool B. It's unethical because the virus creating tool may become available to the public. C. All of the above D. None of the above

B Explanation: As a CISSP, one needs to discourage unsafe practices and/or bad practices, and preserve and strengthen the integrity of the public infrastructures. See "All-in-One Exam Guide" Third Edition by Shon Harris page 753 or www.isc2.org.

1353: __________ sends out a message to all other computers indicating it is going to send out data. A. CSMA/CD B. CSMA/CA C. CSMA/HB D. PPP E. SLIP CISSP Actualtests.com - The Power of Knowing

B Explanation: CSMA/CA sends out a message to all other computers indicating it is going to send out data. CSMA/CA or token ring networking uses this approach to reduce the amount of data collisions. Note: When computers use the carrier sense multiple access with collision detection (CSMA/CD) protocols, they monitor the transmission activity, or carrier activity, on the wire so that they can determine when would be the best time to transmit data. Carrier sense multiple access with collision avoidance (CSMA/CA) is an access method where each computer signals its intent to transmit data before it actually does so. pg 390-391 Shon Harris All-In-One CISSP Certification

1352: CSMA/CD computers cannot communicate without a token.(True/False) A. True B. False

B Explanation: CSMA/CD computers do not use a token. It is the media access method used in Ethernet.

1294: Why would a database be denormalized? A. To ensure data integrity. B. To increase processing efficiency. C. To prevent duplication of data. D. To save storage space.

B Explanation: Denormalization is the process of attempting to optimize the performance of data storage by adding redundant data. It is necessary because current DBMSs are not fully relational. A fully relational DBMS would be able to preserve full normalization at the logical level, while allowing it to be mapped to performance-tuned physical level. Database designers often justify denormalization on performance issues, but they should note that logical denormalization can easily break the consistency of the database, one of the all-important ACID properties. However, a designer can achieve the performance benefits while retraining consistency by performing denormalization at a physical level; such denormalization is often called caching.

1155: Which is a characteristic of IDEA? A. 56 bytes B. 64 bits C. 64 bytes D. All of the above E. None of the above

B Explanation: From Wikipedia: International Data Encryption Algorithm (IDEA) operates on 64-bit blocks using a 128-bit key, and consists of a series of eight identical transformations (a round, see the illustration) and an output transformation (the half-round). The processes for encryption and decryption are similar. IDEA derives much of its security by interleaving operations from different groups - modular addition and multiplication, and bitwise eXclusive OR (XOR) - which are algebraically "incompatible" in some sense.

1225: Which of the following are NOT a countermeasure to traffic analysis? A. Padding messages B. Eavesdropping C. Sending noise D. Covert channel analysis

B Explanation: Lets do this with a elimination process. With padding messages you can countermeasure traffic analysis because you add garbage information to the message to let in end in a fixed length, this can confuse the analyzer. Sending noise on the communication line could also countermeasure analysis because the analyzer don't now how to differentiate between real information and noise. You can also covert channel analysis. Eavesdropping does not apply in this situation, its not considered a counter measure to traffic analysis.

1351: What is the best description for CHAP Challenge Handshake Authentication Protocol? A. Passwords are sent in clear text B. Passwords are not sent in clear text C. Passwords are not used, a digital signature is sent D. It is substandard to PAP E. It was used with PS2's and has been discontinued

B Explanation: Passwords are not sent in clear text. The server performing the authentication sends a challenge value and the user types in the password. The password is used to encrypt the challenge value then is sent back to the authentication server.

1241: Which of the following is most concerned with personnel security? A. Management controls B. Operational controls C. Technical controls D. Human resources controls.

B Explanation: Personnel security always have to deal more with Operational controls, Operational controls provide the guidelines and the correct procedures to implement the different operations. Management controls are usually used only by managers. Human resources and Technical Controls are not related to personal security as the question states. See the different control definitions in your CISSP documentation.

1201: Which of the following is used in database information security to hide information? A. Inheritance B. Polyinstantiation C. Polymorphism D. Delegation

B Explanation: Polyinstantiation represents an environment characterized by information stored in more than one location in the database. This permits a security model with multiple levels-of-view and authorization. The current problem with polyinstantiation is ensuring the integrity of the information in the database. Without an effective method for the simultaneous updating of all occurrences of the same data element - integrity cannot be guaranteed.

1267: What is not true with pre-shared key authentication within IKE / IPsec protocol: A. Pre-shared key authentication is normally based on simple passwords. B. Needs a PKI to work. C. Only one preshared key for all VPN connections is needed. D. Costly key management on large user groups.

B Explanation: Pre-Shared Secret is usually used when both ends of the VPN lacks access to a compatible certificate server. Once you have defined all the endpoints in your VPN, you can establish a password that is used to authenticate the other end of the connection, this is the Pre-Shared secret. Since you are using Pre-Shared key because you don't have an available / compatible certificate server, IPSEC and IKE do not need to use PKI in this case (that actually provides the certificate server infrastructure).

1209: Ensuring that printed reports reach proper users and that receipts are signed before releasing sensitive documents are examples of? A. Deterrent controls B. Output controls C. Information flow controls D. Asset controls

B Explanation: Since we want to deal with printer reports, we are talking about output controls, Why, because printer produce output, and we can control it. As a best practice you can have people dedicated in the company to receive the different print jobs in the printing center, and people that takes care of the confidential information requiring a signature from the sender stating that the document was delivered to the owner in a timely and secure fashion.

1341: Which division of the Orange Book deals with discretionary protection (need-to-know)? A. D B. C C. B D. A

B Explanation: The C division of the Orange Book deals discretionary (need-to-know) protection and, through the inclusion of audit capabilities, for accountability of subjects and the actions they initiate. This information can be checked in the orange book. Just make a search online through it with the words "discretionary protection".

1245: There are more than 20 books in the Rainbow Series. Which of the following covers password management guidelines? A. Orange Book B. Green Book C. Red Book D. Lavender Book

B Explanation: The DoD Password Management Guideline was published at 12 April 1985, it is also called the "Green Book" because of the color of its cover. Here is the password definition according to it: "A character string used to authenticate an identity. Knowledge of the password that is associated with a user ID is considered proof of authorization to use the capabilities associated with that user ID."

1204: What attack involves the perpetrator sending spoofed packet(s) with the SYN flag set to the victim's machine on any open port that is listening? A. Bonk attack B. Land attack C. Teardrop attack D. Smurf attack

B Explanation: The Land attack involves the perpetrator sending spoofed packet(s) with the SYN flag set to the victim's machine on any open port that is listening. If the packet(s) contain the same destination and source IP address as the host, the victim's machine could hang or reboot. In addition, most systems experience a total freeze up, where as CTRL-ALT-DELETE fails to CISSP Actualtests.com - The Power of Knowing work, the mouse and keyboard become non operational and the only method of correction is to reboot via a reset button on the system or by turning the machine off. Vulnerable Systems: This will affect almost all Windows 95, Windows NT, Windows for Workgroups systems that are not properly patched and allow Net Bios over TCP/IP. In addition, machines running services such as HTTP, FTP, Identd, etc that do not filter packet(s), that contain the same source / destination IP address, can still be vulnerable to attack through those ports. Prevention: This attack can be prevented for open / listening ports by filtering inbound packets containing the same source / destination IP address at the router or firewall level. For most home users not running a lot of services, and for those who use IRC, disabling the Identd server within their client will stop most attacks since the identd service (113) is becoming the most attacked service/port.

1328: Encryption is applicable to all of the following OSI/ISO layers except: A. Network layer B. Physical layer C. Session layer D. Data link layer

B Explanation: The Physical Layer describes the physical properties of the various communications media, as well as the electrical properties and interpretation of the exchanged signals. Ex: this layer defines the size of Ethernet coaxial cable, the type of BNC connector used, and the termination method. You cannot encrypt nothing at this layer because its physical, it is not protocol / software based. Network, Data link and transport layer supports encryption.

1167: Which Orange book security rating introduces security labels? A. C2 B. B1 C. B2 D. B3

B CISSP Actualtests.com - The Power of Knowing Explanation: Class (B1) or "Labeled Security Protection" systems require all the features required for class (C2). In addition, an informal statement of the security policy model, data labeling, and mandatory access control over named subjects and objects must be present. The capability must exist for accurately labeling exported information. Any flaws identified by testing must be removed.

1180: Which of the following is not a defined layer in the TCP/IP protocol model? CISSP Actualtests.com - The Power of Knowing A. Application layer B. Session layer C. Internet layer D. Network access layer

B Explanation: The TCP/IP reference model is the network model used in the current Internet architecture. It has its origins back in the 1960's with the grandfather of the Internet, the ARPANET. This was a research network sponsored by the Department of Defense in the United States. The reference model was named after two of its main protocols, TCP (Transmission Control Protocol) and IP (Internet Protocol). They choose to build a packet-switched network based on a connectionless internet layer. Here is a representation of it: "The TCP/IP Protocol Model is similar to the OSI model, but it defines only the following four layers instead of seven: Application Layer. Consists of the applications and processes that use the network. Host-to-Host Transport Layer. Provides end-to-end data delivery service to the Application Layer. Internet Layer. Defines the IP datagram and handles the routing of data across networks. Network Access or Link Layer. Consists of routines for accessing physical networks and the electrical connection."

1212: Which of the following statements pertaining to secure information processing facilities is incorrect? A. Walls should have an acceptable fire rating. B. Windows should be protected by bars. C. Doors must resist forcible entry. D. Location and type of fire suppression systems should be known.

B Explanation: The correct answer can be determined through elimination. We need to have an acceptable fire rating for the walls, this is well known for any CISSP aspirant, its like that because we need to contain the fire as much as we can. We also need resistant doors so unauthorized people do not enter easily using the force. The people also need to know about fire suppression systems to be able to deal with a fire situation inside the facilities. As you can see, We should not protect windows with bars, this is a bad practice because, in the case of a fire, the people cannot get out of the building through the windows.

1223: What uses a key of the same length as the message? A. Running key cipher B. One-time pad C. Steganography D. Cipher block chaining

B Explanation: The one time pad is the most secure, and one of the simplest of all cryptographic methods. It was invented and patented just after World War I by Gilbert Vernam (of AT&T) and Joseph Mauborgne (USA, later chief of the Signal Corps). The fundamental features are that the sender and receiver each have a copy of an encryption key, which is as long as the message to be encrypted, and each key is used for only one message and then discarded. That key must be random, that is without pattern, and must remain unknown to any attacker. In addition, the key must never be reused, otherwise the cipher becomes trivially breakable. One of its features it's the key length, it's the same as the message.

1309: Which of the following is the most reliable authentication device? A. Variable callback system B. Smart Card system C. Fixed callback system D. Combination of variable and fixed callback system.

B Explanation: The smart card, an intelligent token, is a credit card sized plastic card embedded with an integrated circuit chip. It provides not only memory capacity, but computational capability as well. The self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. Because of this characteristic, smart cards are often used in different applications which require strong security protection and authentication. Option B is the most correct option, this is because Callback systems are not considered very reliable in the CISSP examination, Smart cards can also provide 2 mode authentication. "Caller ID and callback options are great, but they are usually not practical because they require users to call in from a static phone number each time they access the network. Most users are accessing the network remotely because they are on the road and moving from place to place." Pg. 428 Shon Harris: All-In-One CISSP Certification Guide. CISSP Actualtests.com - The Power of Knowing

1355: The top speed of ISDN BRI is 256 KBS.(True/False) A. True B. False

B Explanation: The top speed of ISDN BRI is 128 KBS. Its two primary channels are each capable of carrying 64 KBS so the combined top speed is 128 KBS.

1256: Creation and maintenance of intrusion detection systems and processes for the following is one of them identify it: A. Event nonrepudiation B. Event notification C. Netware monitoring D. Guest access

B Explanation: There is not much to explain or comment in here, when you administer an IDS system you have to deal with the maintenance and creation of event notification processes, this have to be reviewed every certain time. This is a well known topic for any Intrusion detection system administrator. This notifications will save your life when your network is being attacked and you get real time notifications that will allow you to shut down your external interface before the attacker gets what he was looking for.

1184: Which of the following Common Data Network Services is used to send and receive email internally or externally through an email gateway device? A. File services B. Mail services C. Print services D. Client/Server services

B Explanation: This functionality is provided through mail services, this service permits collaboration between users in an internal and external level. We usually use two protocols, "SMTP" in port TCP 25 to send the emails and "POP3" in port TCP 110 to receive them. Currently there is another protocol that is gaining popularity, it is "IMAP4". Print services are used for printing documents and file services are used to share and access files and folders inside the infrastructure.

1182: Which one of the following is not a primary component or aspect of firewall systems? A. Protocol filtering B. Packet switching C. Rule enforcement engine D. Extended logging capability

B Explanation: This is not a main function of a firewall, packet switching is a main feature of a Switch (working only in the layer 2 of the OSI model). Firewall are network security devices that can function through layer 2 to layer 7 of the OSI model. They usually include rule engine that enforce the enterprise security policy of the company. They provide protocol filtering to enforce our requirements through the forwarded or deny of traffic. They also provide logging capabilities so we can analyze what is happening in a very low level in our network.

238: Which of the following biometrics devices has the highs Crossover Error Rate (CER)? A.) Iris scan B.) Hang Geometry C.) Voice pattern D.) Fingerprints

279: The primary service provided by Kerberos is which of the following? A.) non-repudiation B.) confidentiality C.) authentication D.) authorization

1211: An effective information security policy should not have which of the following characteristics? A. Include separation of duties. B. Be designed with a short-to mid-term focus. C. Be understandable and supported by all stakeholders. D. Specify areas of responsibility and authority.

B Explanation: This is not a very good practice, specially for the CISSP examination, when you plan and develop the security policy for your enterprise you should always plan it with a long term focus. The policy should be created to be there for a long time, and you should only make revisions of it every certain time to comply with changes or things that could have changed. In a security policy the duties should be well specified, be understandable by the people involved in it, and specify areas of responsibility.

1164: Within the realm of IT security, which of the following combinations best defines risk? A. Threat coupled with a breach. B. Threat coupled with a vulnerability. C. Vulnerability coupled with an attack. D. Threat coupled with a breach of security.

B Explanation: This is the main concept, when we talk about a possible risk we always have a possible vulnerability in the system attacked. This vulnerability can make a threat to be successful. We can say that the level of risk can be measures through the level of vulnerabilities in our current systems and the ability of the attackers to exploit them to make a threat successful.

1307: Which of the following computer aided software engineering (CASE) products is used for developing detailed designs, such as screen and report layouts? A. Lower CASE B. Middle CASE C. Upper CASE D. I-CASE

B Explanation: This is the proper name, you can search for "Middle CASE" on the Internet. CISSP Actualtests.com - The Power of Knowing "Middle CASE" its a CASE flavor and UML design tool that provides the required functionality like screen and report layouts and detailed designs. There are many well known vendors providing this kind of tools for the development process of Software.

1165: Which of the following would be the best reason for separating the test and development environments? CISSP Actualtests.com - The Power of Knowing A. To restrict access to systems under test. B. To control the stability of the test environment. C. To segregate user and development staff. D. To secure access to systems under development.

B Explanation: This is the right answer, with a separation of the two environments (Test and development), we can get a more stable and more "in control" environment, Since we are making tests in the development environment, we don't want our production processes there, we don't want to experiment things in our production processes. With a separation of the environments we can get a more risk free production environment and more control and flexibility over the test environment for the developers.

1260: A contingency plan should address? A. Potential risks B. Residual risks C. Identified risks D. All of the above

B Explanation: This is true, as stated in CISSP documentation, you should address any possible "Residual Risk" at your contingency plan to minimize business impact when you are in a downtime situation. The identified Risks and the Potential Risks are not identified there, they are identified earlier.

1311: The Internet can be utilized by either? A. Public or private networks (with a Virtual Private Networks). B. Private or public networks (with a Virtual Private Networks). C. Home or private networks (with a Virtual Private Networks). D. Public or home networks (with a Virtual Private Networks).

B Explanation: This is true, you can utilize Internet from a Private network and get access through an access translation method that gives you a valid IP address to make the request. Or you can access the Internet directly from a routable, public IP address contained in a public network. To increase security, you can create VPN´s to pass information between two endpoints with confidentiality through the Internet.

1222: Which of the following is a preventive control? A. Motion detectors B. Guard dogs C. Audit logs D. Intrusion detection systems

B Explanation: This is very obvious. Since we want to prevent something from happening, we can go out and buy some Guard dogs to make the job. You are buying them because you want to prevent something from happening. The intruder will see the dogs and will maybe go back, this prevents an attack, this dogs are a form of preventive control. Motion Detectors and IDS are real-time, Audit Logs are passive.

1288: The primary purpose for using one-way encryption of user passwords within a system is which of the following? A. It prevents an unauthorized person from trying multiple passwords in one logon attempt. B. It prevents an unauthorized person from reading or modifying the password list. C. It minimizes the amount of storage required for user passwords. D. It minimizes the amount of processing time used for encrypting passwords.

B Explanation: This kind of encryption flavor increases security for passwords, if you use a one way encryption algorithm, you know that the encryption is not reversible, you cannot get the original value that you provided as a password from the resulting hash with any key or algorithm. This increase security in the way that when a person see the password list, it will only see the hash values and cannot read the original password or modify them without getting corruption.

809: In what type of attack does an attacker try, from several encrypted messages, to figure out the key using the encryption process? A.) Known-plaintext attack B.) Ciphertext-only attack C.) Chosen-Ciphertext attack D.) Known Ciphertext attack

B "Ciphertext-Only Attack In this type of attack, the attacker has the ciphertext of several messages. Each of the messages has been encrypted using the same encryption algorithm. The attacker's goal is to discover the key that was used in the encryption process. Once the attacker figures out the key, she can decrypt all other messages encrypted with the same key. A ciphertext-only attack is the most common because it is very easy to get ciphertext by sniffing someone's traffic, but it is the hardest attack to actually be successful at because the attacker has so little information about the encryption process." Pg 531 Shon Harris CISSP All-In-One Exam Guide

88: To support legacy applications that rely on risky protocols (e.g,, plain text passwords), which one of the following can be implemented to mitigate the risks on a corporate network? A. Implement strong centrally generated passwords to control use of the vulnerable applications. B. Implement a virtual private network (VPN) with controls on workstations joining the VPN. C. Ensure that only authorized trained users have access to workstations through physical access control. D. Ensure audit logging is enabled on all hosts and applications with associated frequent log reviews.

B It makes more sense to provide VPN client to workstations opposed to physically securing workstations.

1171: Which of the following best describes the Secure Electronic Transaction (SET) protocol? A. Originated by VISA and MasterCard as an Internet credit card protocol. B. Originated by VISA and MasterCard as an Internet credit card protocol using digital signatures. C. Originated by VISA and MasterCard as an Internet credit card protocol using the transport layer. D. Originated by VISA and MasterCard as an Internet credit card protocol using SSL.

B Explanation: This protocol was created by VISA and MasterCard as a common effort to make the buying process over the Internet secure through the distribution line of those companies. It is located in layer 7 of the OSI model. SET uses a system of locks and keys along with certified account IDs for both consumers and merchants. Then, through a unique process of "encrypting" or scrambling the information exchanged between the shopper and the online store, SET ensures a payment process that is convenient, private and most of all secure. Specifically, SET: 1. Establishes industry standards to keep your order and payment information confidential. 2. Increases integrity for all transmitted data through encryption. 3. Provides authentication that a cardholder is a legitimate user of a branded payment card account. 4. Provides authentication that a merchant can accept branded payment card transactions through its relationship with an acquiring financial institution. 5. Allows the use of the best security practices and system design techniques to protect all legitimate parties in an electronic commerce transaction. The SET process relies strongly on the use of certificates and digital signatures for the process of authentication and integrity of the information. CISSP Actualtests.com - The Power of Knowing

1187: They in form of credit card-size memory cards or smart cards, or those resembling small calculators, are used to supply static and dynamic passwords are called? A. Token Ring B. Tokens C. Token passing networks D. Coupons

B Explanation: Tokens are usually used to provide authentication through "What we have", is most commonly implemented to provide two-factor authentication. For example, SecurID requires two pieces of information, a password and a token. The token is usually generated by the SecurID token - a small electronic device that users keep with them that display a new number every 60 seconds. Combining this number with the users password allows the SecurID server to determine whatever or not the user should be granted access. CISSP Actualtests.com - The Power of Knowing

1305: Which of the following tools is less likely to be used by a hacker? CISSP Actualtests.com - The Power of Knowing A. I0phtcrack B. Tripwire C. Crack D. John the Ripper

B Explanation: Tripwire is a tool that checks to see what has changed on your system. The program monitors key attributes of files that should not change, including binary signature, size, expected change of size, etc. The hard part is doing it the right way, balancing security, maintenance, and functionality. This tool is not usually used by hackers to attack, its usually used to defend against hackers attacks. L0phtcrack is a hacker utility to get passwords, Crack and John the Ripper are also password crackers.

1304: Which of the following countermeasures is not appropriate for war dialing attacks? A. Monitoring and auditing for such activity. B. Disabling call forwarding. C. Making sure only necessary phone numbers are made public. D. Using completely different numbers for voice and data accesses.

B Explanation: War dialing, or scanning, has been a common activity in the computer underground and computer security industry for decades. Hollywood made war dialing popular with the 1983 movie, War Games, in which a teenager searching for a videogame company ultimately uncovers a government nuclear war warning system. The act of war dialing is extremely simple - a host computer dials a given range of telephone numbers using a modem. Every telephone number that answers with a modem and successfully connects to the host is stored in a log. Disabling call forwarding is not a useful countermeasure because it's the attacker machine the one who connects to the attacked system and forwarding is not an issue inside the attack. Answer A, C and D can be used as countermeasures to harder the war dial attack.

225: A channel within a computer system or network that is designed for the authorized transfer of information is identified as a(n)? A.) Covert channel B.) Overt channel C.) Opened channel D.) Closed channel

B "An overt channel is a channel of communication that was developed specifically for communication purposes. Processes should be communicating through overt channels, not covert channels." Pg 237 Shon Harris: All-In-One CISSP Certification Guide.

895: Which protocol matches an Ethernet address to an Internet Protocol (IP) address? A.) Address Resolution Protocol (ARP) B.) Reverse Address Resolution Protocol (RARP) C.) Internet Control Message Protocol (ICMP) D.) User Datagram Protocol (UDP)

B "As with ARP, Reverse Address Resolution Protocol (RARP) frames go to all systems on the subnet, but only the RARP server responds. Once the RARP server receives this request, it looks in its table to see which IP address matches the broadcast hardware address. The server then sends a message back to the requesting computer that contains its IP address. The system now has an IP address and can function on the network." Pg 357 Shon Harris: All-in-One CISSP Certification

147: At what Trusted Computer Security Evaluation Criteria (TCSEC) or Information Technology Security Evaluation Criteria (ITSEC) security level are database elements FIRST required to have security labels? A. A1/E6 B. B1/E3 C. B2/E4 D. C2/E2

B "B1: Labeled Security Each data object must contain a classification label and each subject must have a clearance label. When a subject attempts to access an object, the system must compare the subject and object's security labels to ensure the requested actions are acceptable. Data leaving the system must also contain an accurate security label. The security policy is based on an informal statement and the design specifications are reviewed and verified. It is intended for environments that require systems to handle classified data." " pg. 224-226 Shon Harris: All-In-One CISSP Certification Exam Guide

Specify which versions of SSL your server can communication with. The latest and most secure version is SSL version 3, but many older clients use only SSL version 2. You will probably want to enable your server to use both versions. 3. Refuse access to any client that does not have a client certificate from a trusted CA by choosing the Yes box under Require client certificates (regardless of access control): 4. Click the OK button and confirm your changes." http://www.verisign.com/repository/clientauth/ent_ig.htm#clientauth

501: Which one of the following entails immediately transmitting copies of on-line transactions to a remote computer facility for backup? A. Archival storage management (ASM) B. Electronic vaulting C. Hierarchical storage management (HSM) D. Data compression

B "Electronic vaulting makes an immediate copy of a changed file or transaction and sends it to a remote location where the original backup is stored....Another technology used for automated backups is hierarrchial storage management (HSM). In this situation, the HSM system dynamically manages the storage and covery of files, which are copied to storage media devices that vary in speed and cost. The faster media hold the data that is accessed more often and the seldom-useed files are stored on the slower devices, or near-line devices. The different storage media rang from optical disk, magnetic disks, and tapes. Pg. 619 Shon Harris CISSP All-In-One Certification Exam Guide CISSP Actualtests.com - The Power of Knowing

B "Other security packages, such as the popular Tripwire data integrity assurance packages, also provide a secondary antivirus functionality. Tripwire is designed to alert administrators of CISSP Actualtests.com - The Power of Knowing unauthorized file modifications. It's often used to detect web server defacements and similar attacks, but it also may provide some warning of virus infections if critical system executable files, such as COMMAND.COM, are modified unexpectedly. These systems work by maintaining a database of hash values for all files stored on the system. These archive hash values are then compared to current computed values to detect any files that were modified between the two periods." Pg. 224 Tittel: CISSP Study Guide

783: Which of the following mail standards relies on a "Web of Trust"? A.) Secure Multipurpose Internet Mail extensions (S/MIME) B.) Pretty Good Privacy (PGP) C.) MIME Object Security Services (MOSS) D.) Privacy Enhanced Mail (PEM)

B "PGP does not use a hierarchy of Cas, or any type of formal trust certificates, but relies on a "web of trust" in its key management approach. Each user generates and distributes his or her public key, and users sign each other's public keys, which creates a community of users who trust each other. This is different than the CA approach where no one trusts each other, they only trust the CA.

674: Which of the following control pairing places emphasis on "soft" mechanisms that support the access control objectives? A.) Preventive/Technical Pairing B.) Preventive/Administrative Pairing C.) Preventive/Physical Pairing D.) Detective/Administrative Pairing

965: The intrusion detection system at your site has detected Internet Protocol (IP) packets where the IP source address is the same as the destination address. This situation indicates A. Misdirected traffic jammed to the internal network. B. A denial of service attack. C. An error in the internal address matrix. D. A hyper overflow in the IP stack.

B "The Land denial of service attack causes many older operating systems (such as Windows NT 4, Windows 95, and SunOS 4.1.4) to freeze and behave in an unpredictable manner. It works by creating an artificial TCP packet that has the SYN flag set. The attacker set the destination IP address to the address of the victim machine and the destination port to an open port on that machine. Next, the attacker set the source IP address and source port to the same values as the destination IP address and port. When the targeted host receives this unusual packet, the operating system doesn't know how to process it and freezes, crashes, or behaves in an unusual manner as a result." Pg 237 Tittel: CISSP Study Guide

845: Which Open Systems Interconnect (OSI) layers provide Transport Control Protocol/Internet Protocol (TCP/IP) end-to-end security? A. Application and presentation B. Presentation and session C. Network and application D. Application and transport

1046: When companies come together to work in an integrated manner such as extranets, special care must be taken to ensure that each party promises to provide the necessary level of protection, liability and responsibility. These aspects should be defined in the contracts that each party signs. What describes this type of liability? A.) Cascade liabilities B.) Downstream liabilities C.) Down-flow liabilities D.) Down-set liabilities CISSP Actualtests.com - The Power of Knowing

B "When companies come together to work in an integrated manner, such as extranets and VANs, special care must be taken to ensure that teach party promises to provide the necessary level of protection, liability, and responsibility needed, which should be clearly defined in the contracts that each party signs. Auditing and testing should be performed to ensure that each party is indeed holding up its side of the bargain and that its technology integrates properly with all other parties. Interoperability can become a large, frustrating, and expensive issue in these types of arrangements. If one of the companies does no provide the necessary level of protection and their negligence affects a partner they are working with, the affected company can sue the upstream company. For example, let's say company A and company B have constructed an extranet. Company A does not put in controls to detect and del with viruses. Company A gets infected with a destructive virus and it is spread to company B through the extranet. The virus corrupts critical data and causes massive disruption to company B's production. Company B can sue company A for being negligent. Both companies need to make sure that they are doing their part to ensure that their activities, or lack of them, will not negatively affect another company, which is referred to as downstream liability." Pg 616 Shon Harris: All-in-One CISSP Certification

944: A TCP SYN Attack: A.) requires a synchronized effort by multiple attackers B.) takes advantage of the way a TCP session is established C.) may result in elevation of privileges. D.) is not something system users would notice

B "[SYN Flood] Attackers can take advantage of this design flaw by continually sending the victim SYN messages with spoofed packets. The victim will commit the necessary resources to setup this communication socket, and it will send its SYN/ACK message waiting for the ACK message in return. However, the victim will never receive the ACK message, because the packet is spoofed, and victim system sent the SYN/ACK message to a computer that does not exist. So the victim system receives a SYN message, add it dutifully commits the necessary resources to setup a connection with another computer. This connection is queued waiting for the ACK message, and the attacker sends another SYN message. The victim system does what is supposed to can commits more resources, sends the SYN/ACK message, and queues this connection. This may only need to happen a dozen times before the victim system no longer has the necessary resources to open up another connection. This makes the victim computer unreachable from legitimate computers, denying other systems service from the victim computer." Pg. 735 Shon Harris CISSP All-In-One Exam Guide

994: What methodology is commonly used in Business Continuity Program? A. Work Group Recovery B. Business Impact Analysis C. Qualitative Risk Analysis D. Quantitative Risk Analysis

B A BIA is performed at the beginning of disaster recovery and continuity planning to identify the areas that would suffer the greatest financial or operational loss in the event of a disaster or disruption. It identifies the company's critical systems needed for survival and estimates the outage time that can be tolerated by the company as a result of disaster or disruption. - Shon Harris All-in-one CISSP Certification Guide pg 597

938: Which one of the following instigates a SYN flood attack? A. Generating excessive broadcast packets. B. Creating a high number of half-open connections. C. Inserting repetitive Internet Relay Chat (IRC) messages. D. A large number of Internet Control Message Protocol (ICMP) traces.

B A SYN attack occurs when an attacker exploits the use of the buffer space during a Transmission Control Protocol (TCP) session initialization handshake. The attacker floods the target system's small "in-process" queue with connection requests, but it does not respond when a target system replies to those requests. This causes the target system to time out while waiting for the proper response, which makes the system crash or become unusable. - Ronald Krutz The CISSP PREP Guide (gold edition) pg 103 "In a SYN flood attack, hackers use special software that sends a large number of fake packets with the SYN flag set to the targeted system. The victim then reserves space in memory for the connection and attempts to send the standard SYN/ACK reply but never hears back from the originator. This process repeats hundreds or even thousands of times, and the targeted computer eventually becomes overwhelmed and runs out of available resources for the half-opened connections. At that time, it either crashes or simply ignores all inbound connection requests because it can't possibly handle any more half-open connections." Pg 266 Tittel: CISSP Study Guide.

570: Audit trails based upon access and identification codes establish... CISSP Actualtests.com - The Power of Knowing A. intrustion detection thresholds B. individual accountability C. audit review critera D. individual authentication

B Accountability is another facet of access control. Individuals on a system are responsible for their actions. This accountability property enables system activities to be traced to the proper individuals. Accountability is supported by audit trails that record events on the system and on the network. Audit trails can be used for intrusion detection and for the reconstruction of past events. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 65

934: Which one of the following attacks is MOST effective against an Internet Protocol Security (IPSEC) based virtual private network (VPN)? A. Brute force B. Man-in-the-middle C. Traffic analysis D. Replay

B Active attacks find identities by being a man-in-the-middle or by replacing the responder in the negotiation. The attacker proceeds through the key negotiation with the attackee until the attackee has revealed its identity. In a well-designed system, the negotiation will fail after the attackee has revealed its identity because the attacker cannot spoof the identity of the originally-intended system. The attackee might then suspect that there was an attack because the other side failed before it gave its identity. Therefore, an active attack cannot be persistent because it would prevent all legitimate access to the desired IPsec system. http://msgs.securepoint.com/cgi-bin/get/ipsec-0201/18.html Not C: Traffic analysis is a good attack but not the most effective as it is passive in nature, while Man in the middle is active.

Client, handler, agent, target C. Source, destination, client, server D. Attacker, proxy, handler, agent

B Another form of DoS. A distributed denial of service occurs when the attacker compromises several systems to be used as launching platforms against one or more victims. The compromised systems used in the attacks are often called claves or zombies. A DDoS attack results in the victims being flooded with data from numerous sources. - Ed Tittle CISSP Study Guide (sybex) pg 693

633: Which of the following is not an example of an operational control? A.) backup and recovery B.) audit trails CISSP Actualtests.com - The Power of Knowing C.) contingency planning D.) operations procedures

B Audit Trails are under Operations Security Auditing opposed to Operations Security Operations Controls. "Operations Controls embody the day-to-day procedures used to protect computer operations.

127: What can be accomplished by storing on each subject a list of rights the subject has for every object? A. Object B. Capabilities C. Key ring D. Rights

B CISSP Actualtests.com - The Power of Knowing Explanation: Capabilities are accomplished by storing on each subject a list of rights the subject has for every object. This effectively gives each user a key ring. To remove access to a particular object, every user (subject) that has access to it must be "touched". A touch is an examination of a user's rights to that object and potentially removal of rights. This brings back the problem of sweeping changes in access rights.

558: Which of the following is a weakness of both statistical anomaly detection and pattern matching? A. Lack of ability to scale. B. Lack of learning model. C. Inability to run in real time. D. Requirement to monitor every event.

B CISSP Actualtests.com - The Power of Knowing Explanation: Disadvantages of Knowledge-based ID systems: This system is resources- intensive; the knowledge database continually needs maintenance and updates New, unique, or original attacks often go unnoticed.Disadvantages of Behavior-based ID systems: The system is characterized by high false alarm rates. High positives are the most common failure of ID systems and can create data noise that makes the system unusable. The activity and behavior of the users while in the networked system might not be static enough to effectively implement a behavior-based ID system. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 88

330: What is called the act of a user professing an identity to a system, usually in the form of a log-on ID? A.) Authentication B.) Identification C.) Integrity D.) Confidentiality

B CISSP Actualtests.com - The Power of Knowing "Identification is the act of a user professing an identity to a system, usually in the form of a logon ID to the system." Pg 49 Krutz The CISSP Prep Guide. "Identification describes a method of ensuring that a subject (user, program, or process) is the entity it claims to be. Identification can be provided with the use of a username or account number. To be properly authenticated, the subject is usually required to provide a second piece to the credential set. This piece could be a password, passphrase, cryptographic key, personal identification number (PIN), anatomical attribute, or token." Pg 110 Shon Harris: All-in-One CISSP Certification

576: In addition to providing an audit trail required by auditors, logging can be used to A. provide backout and recovery information B. prevent security violations C. provide system performance statistics D. identify fields changed on master files.

B CISSP Actualtests.com - The Power of Knowing Auditing tools are technical controls that track activity within a network on a network device or on a specific computer. Even though auditing is not an activity that will deny an entity access to a network or computer, it will track activities so a network administrator can understand the types of access that took place, identify a security breach, or warn the administrator of suspicious activity. This can be used to point out weakness of their technical controls and help administrators understand where changes need to be made to preserve the necessary security level within the environment. . - Shon Harris All-in-one CISSP Certification Guide pg 179-180

1387: What is the best description for CHAP Challenge Handshake Authentication Protocol? A. Passwords are sent in clear text B. Passwords are not sent in clear text C. Passwords are not used, a digital signature is sent D. It is substandard to PAP E. It was used with PS2's and has been discontinued

B CISSP Actualtests.com - The Power of Knowing Passwords are not sent in clear text. The server performing the authentication sends a challenge value and the user types in the password. The password is used to encrypt the challenge value then is sent back to the authentication server.

1068: Which of the following is LEAST necessary when creating evidence tags detailing the chain of custody for electronic evidence? A. The mode and means of transportation. B. Notifying the person who owns the information being seized. C. Complete description of the evidence, including quality if necessary. D. Who received the evidence.

B CISSP Actualtests.com - The Power of Knowing The references indicate that transportation is important. Each piece of evidence should be marked in some way with the date, time, initials of the collector, and a case number if one has been assigned...The pieces of evidence should then be sealed in a container and the container should be marked with the same information. The container should be sealed with evidence tape and if possible, the writing should be on the tape so a broken seal can be detected. - Shon Harris All-in-one CISSP Certification Guide pg 673 In many cases, it is not possible for a witness to uniquely identify an object in court. In those cases, a chain of evidence must be established. This involves everyone who handles evidence - including the police who originally collect it, the evidence technicians who process it, and the lawyers who use it in court. The location of the evidence must be fully documented from the moment it was collected to the moment it appears in court to ensure that it is indeed the same item. This requires thorough labeling of evidence and comprehensive logs noting who had access to the evidence at specific times and the reasons they required such access." Pg. 593 Tittel: CISSP Study Guide. The evidence life cycle covers the evidence gathering and application process. This life cycle has the following components: Discovery and recognition Protection Recording Collection Collect all relevant storage media Make image of hard disk before removing power Print out screen Avoid degaussing equipment Identification Preservation Protect magnetic media from erasure Store in proper environment Transportation Presentation in a court of law Return of evidence to owner Pg. 309 Krutz: The CISSP Prep Guide The life cycle of evidence includes * Collection and identification * Storage, preservation, and transportation * Presentation in court * Being returned to victim or owner Pg 677 Shon Harris: All-In-One CISSP Certification Exam Guide

1389: __________ sends out a message to all other computers indicating it is going to send out data. A. CSMA/CD B. CSMA/CA C. CSMA/HB D. PPP E. SLIP

B CSMA/CA sends out a message to all other computers indicating it is going to send out data. CSMA/CA or token ring networking uses this approach to reduce the amount of data collisions.

1086: A country that fails to legally protect personal data in order to attract companies engaged in collection of such data is referred to as a A. data pirate B. data haven C. country of convenience D. sanctional nation

B Correct answer is B. Data Haven. Data Haven A place where data that cannot legally be kept can be stashed for later use; an offshore web host. CISSP Actualtests.com - The Power of Knowing This is an interesting topic; companies often need information that they are not legally allowed to know. For example, some hospitals are not allowed to mark patients as HIV positive (because it stigmatizes patients); staff members create codes or other ways so can take the necessary steps to protect themselves. http://www.technovelgy.com/ct/content.asp?Bnum=279 DATA HAVEN This phrase has been around for at least 15 years, but only in a specialist way. One sense is that of a place of safety and security for electronic information, for example where encrypted copies of crucial data can be stored as a backup away from one's place of business. But it can also mean a site in which data can be stored outside the jurisdiction of regulatory authorities. This sense has come to wider public notice recently as a result of Neal Stephenson's book Cryptonomicon, in which the establishment of such a haven in South East Asia is part of the plot. In a classic case of life imitating art, there is now a proposal to set up a data haven on one of the old World War Two forts off the east coast of Britain, which declared independence under the name of Sealand back in 1967 (it issues its own stamps and money, for example). The idea is to get round a proposed British law-the Regulation of Investigatory Powers Bill (RIP)-that would force firms to hand over decryption keys if a crime is suspected and make Internet providers install equipment to allow interception of e-mails by the security services. The Privacy Act doesn't protect information from being transferred from New Zealand to data havens-countries that don't have adequate privacy protection. [Computerworld, May 1999] The government last night poured cold water on a plan by a group of entrepreneurs to establish a "data haven" on a rusting iron fortress in the North Sea in an attempt to circumvent new anti-cryptography laws.

Two certificates for the gateway and two for the acquirers. C. Two certificates for each acquirer. D. Two certificates for the gateway and two for each acquirer. CISSP Actualtests.com - The Power of Knowing

B I think it may be D two for each acquirer. Which unless I read it wrong it means each person must have 2 certificates exchanged with the gateway. "SET uses a des symmetric key system for encryption of the payment information and uses rsa for the symmetric key exchange and digital signatures. SET covers the end-to-end transaction from the cardholder to the financial institution". -Ronald Krutz The CISSP PREP Guide (gold edition) pg 219-220 In the SET environment, there exists a hierarchy of Certificate Authorities. The SET protocol specifies a method of entity authentication referred to as trust chaining. This method entails the exchange of digital certificates and verification of the public keys by validating the digital signatures of the issuing C A. This trust chain method continues all the way up to the CA at the top of the hierarchy, which is referred to as the SET Root C A. The SET Root CAis owned and maintained by SET Secure Electronic Transaction LLC. http://setco.org/certificates.html

736: What uses a key of the same length as the message? A.) Running key cipher B.) One-time pad C.) Steganography D.) Cipher block chaining

B Reference: "A one-time pad is an extremely powerful type of substitution cipher. One-time pads use a different alphabet for each letter of the plaintext message. Normally, one-time pads are written as a very long series of numbers to be plugged into the function. The great advantage to one-time pads is that, when used properly, they are an unbreakable encryption scheme. There is no repeating pattern of alphabetic substitution, redering cryptanalytic efforts useless. However, several requirements must be met to ensure the integrity of the algorithm: The encryption key must be randomly generated. Using a phrase or a passage from a book would introduce the possibility of cryptanalysts breaking the code. The one-time pad must be physically secured against disclosure. If the enemy has a copy of the pad, they can easily decrypt the enciphered messages. Each one-time pad must be used only once. If pads are reused, cryptanalysts can compare similarities in multiple messages encrypted with the same pad and possibly determine the key values used. The key must be at least as long as the message to be encrypted. This is because each key element is used to encode only one character of the message.

Keeping data objects small, simple, and obvious as to their intent. D. Limiting connectivity by means of well-managed access controls.

B Take as general information regarding worms "Although the worm is not technically malicious, opening the attachment allows the file to copy itself to the user's PC Windows folder and then send the .pif-based program to any e-mail address stored on the hard drive. Ducklin said the huge risks associated with accepting program files such as .pif, .vbs (visual basic script) or the more common .exe (executable) as attachments via e-mail outweighs the usefulness of distributing such files in this manner. "There's no business sense for distributing programs via e-mail," he said. To illustrate the point, Ducklin said six of the top 10 viruses reported to Sophos in April spread as Windows programs inside e-mails." http://security.itworld.com/4340/030521stopworms/page_1.html

1078: Why is the investigation of computer crime involving malicious damage especially challenging? A. Information stored in a computer is intangible evidence. B. Evidence may be destroyed in an attempt to restore the system. C. Isolating criminal activity in a detailed audit log is difficult. D. Reports resulting from common user error often obscure the actual violation.

B The gathering, control, storage, and preservation of evidence are extremely critical in any legal investigation. Because evidence involved in a computer crime might be intangible and subject to easy modification without a trace, evidence must be carefully handled and controlled throughout its entire life cycle. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 432

667: The concentric circle approach is used to A. Evaluate environmental threats. B. Assess the physical security facility, C. Assess the communications network security. D. Develop a personnel security program.

B The original answer for this question was C (assess the communications network security) however I think the concentric circle is defining what in the krutz book is know as the security perimeter. To this end this is a reference "A circular security perimeter that is under the access control defines the area or zone to be protected. Preventive/physical controls include fences, badges, multiple doors (man-traps that consists of two doors physically separated so that an individual can be 'trapped' in the space between the doors after entering one of the doors), magnetic card entry systems, biometrics (for identification), guards, dogs, environmental control systems (temperature, humidity, and so forth), and building and access area layout." -Ronald Krutz The CISSP PREP Guide (gold edition) pg 13 This is a standard concentric circle model shown in Figure 1 . If you've never seen this, you haven't had a security lecture. On the outside is our perimeter. We are fortunate to have some defenses on our base. Although some bases don't have people guarding the gates and checking IDs any longer, there's still the perception that it's tougher to commit a crime on a Naval base than it would be at GM. The point is: How much control do we have over fencing and guards? The answer: Not much. The next circle, the red circle, contains your internal access controls. For our purposes, the heart of the red circle is the computer. That's what I want to zero in on. The internal controls are the things you can do to keep people out of your PCs and off your network. http://www.chips.navy.mil/archives/96_oct/file5.htm

884: Which one of the following is a technical solution for the quality of service, speed, and security problems facing the Internet? A. Random Early Detection (RED) queuing B. Multi-protocol label-switching (MPLS) C. Public Key Cryptography Standard (PKCS) D. Resource Reservation Protocol (RSVP)

B The original answer to this question was RED however I think this is incorrect because of this reason. Both Red and MPLS deal with qos/cos issues, there by increasing speed. Mpls more so the RED. However I have not been able to find any documents that state RED is a security implementation while MPLS is heavy used in the ISP VPN market. See this link for MPLS security http://www.nwfusion.com/research/2001/0521feat2.html Below are the link that are formation of the ration for this answer of B (MPLS) Congestion avoidance algorithm in which a small percentage of packets are dropped when congestion is detected and before the queue in question overflows completely http://www.cisco.com/univercd/cc/td/doc/cisintwk/ita/r12.htm Multiprotocol Label Switching. Switching method that forwards IP traffic using a label. This label instructs the routers and the switches in the network where to forward the packets based on preestablished IP routing information http://www.cisco.com/univercd/cc/td/doc/cisintwk/ita/m12.htm Resource Reservation Protocol. Protocol that supports the reservation of resources across an IP network. Applications running on IP end systems can use RSVP to indicate to other nodes the nature (bandwidth, jitter, maximum burst, and so on) of the packet streams they want to receive. RSVP depends on IPv6. Also known as Resource Reservation Setup Protocol. http://www.cisco.com/univercd/cc/td/doc/cisintwk/ita/r12.htm Random Early Detection (RED) is the recommended approach for queue congestion management in routers (Braden et al., 1998). Although in its basic form RED can be implemented in a relatively short C program, as the speed of ports and the number of queues per port increase, the implementation moves more and more into hardware. Different vendors choose different ways to implement and support RED in their silicon implementations. The degree of programmability, the number of queues, the granularity among queues, and the calculation methods of the RED parameters all vary from implementation to implementation. Some of these differences are irrelevant to the behavior of the algorithm-and hence to the resulting network behavior. Some of the differences, however, may result in a very different behavior of the RED algorithm-and hence of the network efficiency. http://www.cisco.com/en/US/products/hw/routers/ps167/products_white_paper09186a0080091fe4.shtml Based on label swapping, a single forwarding mechanism provides opportunities for new control CISSP Actualtests.com - The Power of Knowing paradigms and applications. MPLS Label Forwarding is performed with a label lookup for an incoming label, which is then swapped with the outgoing label and finally sent to the next hop. Labels are imposed on the packets only once at the edge of the MPLS network and removed at the other end. These labels are assigned to packets based on groupings or forwarding equivalence classes (FECs). Packets belonging to the same FEC get similar treatment. The label is added between the Layer 2 and the Layer 3 header (in a packet environment) or in the virtual path identifier/virtual channel identifier (VPI/VCI) field (in ATM networks). The core network merely reads labels, applies appropriate services, and forwards packets based on the labels. This MPLS lookup and forwarding scheme offers the ability to explicitly control routing based on destination and source addresses, allowing easier introduction of new IP services. http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/xlsw_ds.htm

1014: To mitigate the impact of a software vendor going out of business, a company that uses vendor software should require which one of the following? A. Detailed credit investigation prior to acquisition. B. Source code held in escrow. C. Standby contracts with other vendors. D. Substantial penalties for breech of contract.'

B The original answer was C however this is incorrect for this case. SLA and standby are good ideas but in this case B is right. "A software escrow arrangement is a unique tool used to protect a company against the failure of a software developer to provide adequate support for its products or against the possibility that the developer will go out of business and no technical support will be available for the product....Under a software escrow agreement, the developer provides copies of the application source code to an independent third-party organization. The third party then maintains updated backup copies of the source code in a secure fashion. The agreement between the end user and the developer specifies "trigger events", such as the failure of the developer to meet terms of a service level agreement (SLA) or the liquidation of the developer's firm." - Ed Tittle CISSP Study Guide (sybex) pg 550

973: Which one of the following could a company implement to help reduce PBX fraud? A. Call vectoring B. Direct Inward System Access (DISA) C. Teleconferencing bridges D. Remote maintenance ports

B The potential for fraud to occur in voice telecommunications equipment is a serious threat. PBX's (Private Branch Exchange) are telephone switches used within state agencies to allow employees to make out-going and receive incoming phone calls. These PBX's can also provide connections for communications between personal computers and local and wide area networks. Security measures must be taken to avoid the possibility of theft of either phone service or information through the telephone systems. Direct Inward System Access (DISA) is the ability to call into a PBX, either on an 800 number or a local dial- in, and by using an authorization code, gain access to the long distance lines and place long distance calls through the PBX http://www.all.net/books/Texas/chap10.html

949: Which one of the following is an example of hyperlink spoofing? A. Compromising a web server Domain Name Service reference. B. Connecting the user to a different web server. C. Executing Hypertext Transport Protocol Secure GET commands. D. Starting the user's browser on a secured page.

B The problem is that most users do not request to connect to DNS names or even URLs, they follow hyperlinks... But, whereas DNS names are subject to "DNS spoofing" (whereby a DNS server lies about the internet address of a server) so too are URLs subject to what I call "hyperlink spoofing" or "Trojan HTML", whereby a page lies about an URLs DNS name. Both forms of spoofing have the same effect of steering you to the wrong internet site, however hyperlink spoofing is technically much easier than DNS spoofing. http://www.brd.ie/papers/sslpaper/sslpaper.html

231: What security risk does a covert channel create? A. A process can signal information to another process. B. It bypasses the reference monitor functions. C. A user can send data to another user. D. Data can be disclosed by inference.

B The risk is not that a process can signal another process. The risk is that the signaling bypasses the reference monitor functions (ie the communication is not screened by the security kernel that implements the reference monitor).

B This applet can execute in the network browser and may contain malicious code. The types of downloadable programs are also known as mobile code. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 361 "ActiveX Controls are Microsoft's answer to Sun's Java applets. They operate in a very similar fashion, but they are implemented using any on of a variety of languages, including Visual Basic, C, C++ and Java. There are two key distinctions between Java applets and ActiveX controls. First, ActiveX controls use proprietary Microsoft technology and, therefore, can only execute on systems running Microsoft operating systems. Second, ActiveX controls are not CISSP Actualtests.com - The Power of Knowing subject to the sandbox restrictions placed on Java applets. They have full access to the Windows operating environment and can perform a number of privileged actions. Therefore, special precautions must be taken when deciding which ActiveX controls to download and execute.

519: In what way could Java applets pose a security threat? A.) Their transport can interrupt the secure distribution of World Wide Web pages over the Internet by removing SSL and S-HTTP B.) Java interpreters do not provide the ability to limit system access that an applet could have on a client system C.) Executables from the Internet may attempt an intentional attack when they are downloaded on a client system D.) Java does not check the bytecode at runtime or provide other safety mechanisms for program isolation from the client system.

C Explanation: "Java Security Java applets use a security scheme that employs a sandbox to limit the applet's access to certain specific areas within the user's system and protects the system from malicious or poorly written applets. The applet is supposed to run only within the sandbox. The sandbox restricts the applet's environment by restricting access to a user's hard drives and system resources. If the applet does not go outside the sandbox, it is considered safe. However, as with many other things in the computing world, the bad guys have figured out how to escape their confines and restrictions. Programmers have figured out how to write applets that enable the code to access hard drives and resources that are supposed to be protected by the Java security scheme. This code can be malicious in nature and cause destruction and mayhem to the user and her system. Java employs a sandbox in its security scheme, but if an applet can escape the confines of the sandbox, the system can be easily compromised."

C Explanation: Anomaly detectors identify abnormal unusual behavior (anomalies) on a host or network. They function on the assumption that attacks are different from "normal" (legitimate) activity and can therefore be detected by systems that identify these differences. Anomaly detectors construct profiles representing normal behavior of users, hosts, or network connections. These profiles are constructed from historical data collected over a period of normal operation. The detectors then collect event data and use a variety of measures to determine when monitored activity deviates from the norm.

337: A smart card represents: CISSP Actualtests.com - The Power of Knowing A. Something you are. B. Something you know. C. Something you have. D. All of the choices.

C Explanation: Another form of authentication requires possession of something such as a key, a smart card, a disk, or some other device. Whatever form it takes, the authenticating item should be difficult to duplicate and may require synchronization with systems other than the one to which you are requesting access. Highly secure environments may require you to possess multiple things to guarantee authenticity.

290: Which of the following factors may render a token based solution unusable? A. Token length B. Card size C. Battery lifespan D. None of the choices.

C Explanation: Another limitation of some of the tokens is their battery lifespan.

Some token companies such as Cryptocard have introduced tokens that have a small battery compartment allowing you to change the battery when it is discharged.

391: With MAC, who may make decisions that bear on policy? A. None of the choices. B. All users. C. Only the administrator. D. All users except guests.

C Explanation: As the name implies, the Mandatory Access Control defines an imposed access control level. MAC is defined as follows in the Handbook of Information Security Management: With mandatory controls, only administrators and not owners of resources may make decisions that bear on or derive from policy. Only an administrator may change the category of a resource, and no one may grant a right of access that is explicitly forbidden in the access control policy.

170: With the BLP model, access permissions are defined through: CISSP Actualtests.com - The Power of Knowing A. Filter rules B. Security labels C. Access Control matrix D. Profiles

C Explanation: Bell-LaPadula is a state machine model capturing confidentiality aspects of access control. Access permissions are defined through an Access Control matrix and through a partial ordering of security levels. Security policies prevent information flowing downwards from a high security level to a low security level. BLP only considers the information flow that occurs when a subject observes or alters an object.

304: Which of the following are proprietarily implemented by CISCO? A. RADIUS+ B. TACACS C. XTACACS and TACACS+ D. RADIUS

C Explanation: Cisco implemented an enhanced version of TACACS, known as XTACACS (extended TACACS), which was also compatible with TACACS. It allowed for UDP and TCP encoding. XTACACS contained several improvements: It provided accounting functionality to track length of login and which hosts a user connected to, and it also separated the authentication, authorization, and accounting processes such that they could be independently implemented. None of the three functions are mandatory. XTACACS is described in RFC CISSP Actualtests.com - The Power of Knowing 1492. TACACS+ is the latest Cisco implementation. It is best described as XTACACS with improved attribute control (authorization) and accounting.

C Explanation: TACACS integrates the authentication and authorization processes. XTACACS keeps the authentication, authorization and accounting processes separate. TACACS+ improves XTACACS by adding two-factor authentication. - Ed Tittle CISSP Study Guide (sybex) pg 745

381: With Discretionary access controls, who determines who has access and what privilege they have? A. End users. B. None of the choices. C. Resource owners. D. Only the administrators.

C Explanation: Discretionary access controls can extend beyond limiting which subjects can gain what type of access to which objects. Administrators can limit access to certain times of day or days of the week. Typically, the period during which access would be permitted is 9 a.m. to 5 p.m. Monday through Friday. Such a limitation is designed to ensure that access takes place only when supervisory personnel are present, to discourage unauthorized use of data. Further, subjects' rights to access might be suspended when they are on vacation or leave of absence. When subjects leave an organization altogether, their rights must be terminated rather than merely suspended. Under this type of control, the owner determines who has access and what privilege they have.

357: Which of the following can be used to protect your system against brute force password attack? A. Decrease the value of password history. B. Employees must send in a signed email before obtaining a password. C. After three unsuccessful attempts to enter a password, the account will be locked. D. Increase the value of password age.

C Explanation: Employees must show up in person and present proper identification before obtaining a new or changed password (depending on your policy). After three unsuccessful attempts to enter a password, the account will be locked and only an administrator or the help desk can reactivate the involved user ID.

1295: Under "Named Perils" form of Property insurance CISSP Actualtests.com - The Power of Knowing A. Burden of proof that particular loss is covered is on Insurer. B. Burden of proof that particular loss is not covered is on Insurer. C. Burden of proof that particular loss is covered is on Insured. D. Burden of proof that particular loss is not covered is on Insured.

C Explanation: Here is something on "Named Perils" for your understanding: "Named Perils is a formal and specific listing of perils covered in a policy providing property insurance. A policy covering for damage by fire is said to cover for "the named peril" of fire". As you can see, Answer C is correct.

542: IDSs verify, itemize, and characterize threats from: CISSP Actualtests.com - The Power of Knowing A. Inside your organization's network. B. Outside your organization's network. C. Outside and inside your organization's network. D. The Internet.

C Explanation: IDSs verify, itemize, and characterize the threat from both outside and inside your organization's network, assisting you in making sound decisions regarding your allocation of computer security resources. Using IDSs in this manner is important, as many people mistakenly deny that anyone (outsider or insider) would be interested in breaking into their networks. Furthermore, the information that IDSs give you regarding the source and nature of attacks allows you to make decisions regarding security strategy driven by demonstrated need, not guesswork or folklore.

363: Which one of the following BEST describes a password cracker? A. A program that can locate and read a password file. B. A program that provides software registration passwords or keys. C. A program that performs comparative analysis. D. A program that obtains privileged access to the system.

C Explanation: In a dictionary crack, L0phtCrack encrypts (i.e., hashes) all the passwords in a dictionary file you specify and compares every result with the password hash. If L0phtCrack finds any matches, it knows the password is the dictionary word. L0phtCrack comes with a default dictionary file, words-english. You can download additional files from the Internet or create a custom file. In the Tools Options dialog box, you can choose to run the dictionary attack against the LANMAN password hash, the NT LAN Manager (NTLM) password hash, or both (which is the default). In a hybrid crack, L0phtCrack extends the dictionary crack by appending numbers or symbols to each word in the dictionary file. For example, in addition to trying "Galileo," L0phtCrack also tries "Galileo24," "13Galileo," "?Galileo," "Galileo!," and so on. The default number of characters L0phtCrack tries is two, and you can change this number in the Tools Options dialog box. In a brute-force crack, L0phtCrack tries every possible combination of characters in a character set. L0phtCrack offers four character sets, ranging from alpha only to all alphanumeric plus all symbol characters. You can choose a character set from the Character Set drop-down box in the Tools Options dialog box or type a custom character set in the Character Set drop-down box. L0phtCrack saves custom sets in files with an .lc extension. You can also specify a character set in the password file, as the example in Figure 2 shows. Not B: A key generator is what is being described by the registration password or key answer.

57: Which one of the following is the PRIMARY objective of penetration testing? A. Assessment B. Correction C. Detection D. Protection CISSP Actualtests.com - The Power of Knowing

C Explanation: Its goal is to measure an organization's resistance to an attack and to uncover any weakness within the environment...The result of a penetration test is a report given to management describing the list of vulnerabilities that were identified and the severity of those vulnerabilities. - Shon Harris All-in-one CISSP Certification Guide pg 837-839 Not A: Assessment would imply management deciding whether they can live with a given vulnerability.

575: You should keep audit trail on which of the following items? A. Password usage. B. All unsuccessful logon. C. All of the choices. D. All successful logon.

C Explanation: Keep audit trail of password usage; log all Successful logon, Unsuccessful logon, Date, Time, ID, Login name. Control maximum logon attempt rate where possible.Where possible users must be automatically logged off after 30 minutes of inactivity.

960: Land attack attacks a target by: A. Producing large volume of ICMP echos. B. Producing fragmented IP packets. C. Attacking an established TCP connection. D. None of the choices.

C Explanation: Land.c. attack -- Attacks an established TCP connection. A program sends a TCP SYN packet giving the target host address as both the sender and destination using the same port causing the OS to hang.

562: Which of the following is an obvious disadvantage of deploying misuse detectors? A. They are costly to setup. B. They are not accurate. C. They most be constantly updated with signatures of new attacks. D. They are costly to use.

C Explanation: Misuse detectors can only detect those attacks they know about - therefore they must be constantly updated with signatures of new attacks. Many misuse detectors are designed to use tightly defined signatures that prevent them from detecting variants of common attacks. State-based misuse detectors can overcome this limitation, but are not commonly used in commercial IDSs.

55: Management can expect penetration tests to provide all of the following EXCEPT A. identification of security flaws B. demonstration of the effects of the flaws C. a method to correct the security flaws. D. verification of the levels of existing infiltration resistance

C Explanation: Not B: It is not the objective of the pen tester to supply a method on how to correct the flaws. In fact management may decide to accept the risk and not repair the flaw. They may be able to demonstrate the effects of a flaw - especially if they manage to clobber a system! Penetration testing is a set of procedures designed to test and possibly bypass security controls of a system. Its goal is to measure an organization's resistance to an attack and to uncover any weaknesses within the environment...The result of a penetration test is a report given to management describing the list of vulnerabilities that were identified and the severity of those vulnerabilities. From here, it is up to management to determine how the vulnerabilities are dealt with and what countermeasures are implemented. - Shon Harris All-in-one CISSP Certification Guide pg 837-839

320: Which of the following is NOT a good password deployment guideline? A. Passwords must not be he same as user id or login id. B. Password aging must be enforced on all systems. C. Password must be easy to memorize. D. Passwords must be changed at least once every 60 days, depending on your environment.

C Explanation: Passwords must be changed at least once every 60 days (depending on your environment). Password aging or expiration must be enforced on all systems. Upon password expiration, if the password is not changed, only three grace logins must be allowed then the account must be disable until reset by an administrator or the help desk. Password reuse is not allowed (rotating passwords).

959: What attack is primarily based on the fragmentation implementation of IP and large ICMP packet size? A. Exhaustive B. Brute force C. Ping of Death D. Spoofing

C Explanation: Ping of Death -- This exploit is based on the fragmentation implementation of IP whereby large packets are reassembled and can cause machines to crash. 'Ping of Death CISSP Actualtests.com - The Power of Knowing takes advantage of the fact that it is possible to send an illegal ICMP Echo packet with more than the allowable 65, 507 octets of data because of the way fragmentation is performed. A temporary fix is block ping packets. Ideally, an engineer should secure TCP/IP from overflow when reconstructing IP fragments.

294: Processor card contains which of the following components? A. Memory and hard drive. B. Memory and flash. C. Memory and processor. D. Cache and processor.

C Explanation: Processor cards contain memory and a processor. They have remarkable data processing capabilities. Very often the data processing power is used to encrypt/decrypt data, which makes this type of card a very unique personal identification token. Data processing also permits dynamic storage management, which enables the realization of flexible multifunctional cards.

306: RADIUS is defined by which RFC? A. 2168 B. 2148 C. 2138 D. 2158

C Explanation: RADIUS is a protocol for carrying authentication, authorization, and configuration information between a Network Access Server, which desires to authenticate its links and a shared Authentication Server. RADIUS is a standard published in RFC2138 as mentioned above.

606: Separation of duties is valuable in deterring: A. DoS B. external intruder C. fraud D. trojan house

C Explanation: Separation of duties is considered valuable in deterring fraud since fraud can occur if an opportunity exists for collaboration between various jobs related capabilities. Separation of duty requires that for particular sets of transactions, no single individual be allowed to execute all transactions within the set. The most commonly used examples are the separate transactions needed to initiate a payment and to authorize a payment. No single individual should be capable of executing both transactions.

607: What principle requires that for particular sets of transactions, no single individual be allowed to execute all transactions within the set? A. Use of rights B. Balance of power C. Separation of duties D. Fair use

213: What scheme includes the requirement that the system maintain the separation of duty requirement expressed in the access control triples? A. Bella B. Lattice C. Clark-Wilson D. Bell-LaPadula

C Explanation: Separation of duty is necessarily determined by conditions external to the computer system. The Clark-Wilson scheme includes the requirement that the system maintain the separation of duty requirement expressed in the access control triples. Enforcement is on a per-user basis, using the user ID from the access control triple.

1178: Which of the following backup methods is most appropriate for off-site archiving? A. Incremental backup method. B. Off-site backup method. C. Full backup method. D. Differential backup method.

C Explanation: Since we want to maintain the backups offsite, its always better to send FULL-Backups because they contain a consistent base of the system. We perform the beginning of a restore through a full backup. Remember that the backups stored offsite are in most cases in a secure place, full backup in there are a best practice for any network administrator. With incremental or differential backups we don't have all we need to restore a system to a consistent state. We need to start from the full backup. "Offsite Backup" is not a valid backup method.

299: A method for a user to identify and present credentials only once to a system is known as: A. SEC B. IPSec C. SSO D. SSL

C Explanation: Single Sign-On (SSO) - This is a method for a users to identify and present credentials only once to a system. Information needed for future system access to resources is forwarded by the initial System. BENEFITS More efficient user log-on process Users select stronger passwords Inactivity timeout and attempt thresholds applied uniformly closer to user point of CISSP Actualtests.com - The Power of Knowing entry Improved timely disabling of all network/computer accounts for terminated users

779: Which of the following encryption algorithms does not deal with discrete logarithms? A.) El Gamal B.) Diffie-Hellman C.) RSA D.) Elliptic Curve

C Reference: pg 416 Hansche: Official (ISC)2 Guide to the CISSP Exam

410: With Rule Based Security Policy, global rules usually rely on comparison of the _______ of the resource being accessed. CISSP Actualtests.com - The Power of Knowing A. A group of users. B. Users C. Sensitivity D. Entities

C Explanation: The RFC 2828 - Internet Security Glossary talks about Rule Based Security Policy: A security policy based on global rules imposed for all users. These rules usually rely on comparison of the sensitivity of the resource being accessed and the possession of corresponding attributes of users, a group of users, or entities acting on behalf of users.

1208: During which phase of an IT system life cycle are security requirements developed? A. Operation B. Initiation C. Development D. Implementation

C Explanation: The System Development Life Cycle is the process of developing information systems through investigation, analysis, design, implementation, and maintenance. The System Development Life Cycle (SDLC) is also known as Information Systems Development or Application Development. If you take a look at the standard IT system life cycle chart, you will see that everything that deals with security requirements is done at the "development" CISSP Actualtests.com - The Power of Knowing stage. In this stage you can create the access controls, the form of authentication to use and all the other security requirements.

216: The lattice-based model aims at protecting against: A. Illegal attributes. B. None of the choices. C. Illegal information flow among the entities. D. Illegal access rights

C Explanation: The lattice-based model aims at protecting against illegal information flow among the entities. One security class is given to each entity in the system. A flow relation CISSP Actualtests.com - The Power of Knowing among the security classes is defined to denote that information in one class can flow into another class.

272: In terms of the order of acceptance, which of the following technologies is the MOST accepted? A. Hand geometry B. Keystroke pattern C. Voice Pattern D. Signature

C Explanation: The order of acceptance has slightly changed in the past years. It was Iris that was the most accepted method three years ago but today we have Voice Pattern that is by far the most accepted. Here is the list from most accepted first to least accepted at the bottom of the list: Voice Pattern Keystroke pattern CISSP Actualtests.com - The Power of Knowing Signature Hand geometry Handprint Fingerprint Iris Retina pattern

593: The principle of _________ is a principle by which specific action can be traced back to anyone of your users. A. Security B. Integrity C. Accountability D. Policy

C Explanation: The principle of accountability has been described in many reference; it is a CISSP Actualtests.com - The Power of Knowing principle by which specific action can be traced back to an individual. As mentioned by Idrach, any significant action should be traceable to a specific user. The definition of "Significant" is entirely dependant on your business circumstances and risk management model. It was also mentioned by Rino that tracing the actions of a specific user is fine but we must also be able to ascertain that this specific user was responsible for the uninitiated action.

361: Which one of the following conditions is NOT necessary for a long dictionary attack to succeed? A. The attacker must have access to the target system. B. The attacker must have read access to the password file. C. The attacker must have write access to the password file. D. The attacker must know the password encryption mechanism and key variable.

C Explanation: The program encrypts the combination of characters and compares them to the encrypted entries in the password file. If a match is found, the program has uncovered a password. - Shon Harris All-in-one CISSP Certification Guide pg 199

1266: Which software development model is actually a meta-model that incorporates a number of the software development models? A. The Waterfall model. B. The modified Waterfall model. C. The Spiral model. D. The Critical Patch Model (CPM).

C Explanation: The spiral model for software engineering has evolved to encompass the best features of the classic waterfall model, while at the same time adding an element known as risk analysis. The spiral model is more appropriate for large, industrial software projects and CISSP Actualtests.com - The Power of Knowing has four main blocks/quadrants. Each release or version of the software requires going through new planning, risk analysis, engineering and customer evaluation phases and this is illustrated in the model by the spiral evolution outwards from the center. For each new release of a software product, a risk analysis audit should be performed to decide whether the new objectives can be completed within budget (time and costs), and decisions have to be made about whether to proceed. The level of planning and customer evaluation is missing from the waterfall model which is mainly concerned with small software programs. The spiral model also illustrated the evolutionary development of software where a solution may be initially proposed which is very basic (first time round the loop) and then later releases add new features and possibly a more elaborate GUI.

59: What is the FIRST step that should be considered in a penetration test? A. The approval of change control management. B. The development of a detailed test plan. C. The formulation of specific management objectives. D. The communication process among team members.

C Explanation: The type of penetration test depends on the organization, its security objectives, and the management's goals. - Shon Harris All-in-one CISSP Certification Guide pg 838 CISSP Actualtests.com - The Power of Knowing

652: As a type of access control, which of the following asks for discouraging occurrence? A. Detective B. Intrusive C. Deterrent D. Preventive

C Explanation: There are different types of access control. Access controls can be categorized as follows: Preventive (in order to avoid occurrence) Detective (in order to detect or identify occurrences) Deterrent (in order to discourage occurrences) CISSP Actualtests.com - The Power of Knowing Corrective (In order to correct or restore controls) Recovery (in order to restore resources, capabilities, or losses)

651: As a type of access control, which of the following asks for identifying occurrences? A. Deterrent B. Preventive C. Detective D. Intrusive

C Explanation: There are different types of access control. Access controls can be categorized as follows: Preventive (in order to avoid occurrence) Detective (in order to detect or identify occurrences) Deterrent (in order to discourage occurrences) Corrective (In order to correct or restore controls) Recovery (in order to restore resources, capabilities, or losses)

653: As a type of access control, which of the following asks for restoring controls? A. Deterrent B. Intrusive C. Corrective D. Preventive

C Explanation: There are different types of access control. Access controls can be categorized as follows: Preventive (in order to avoid occurrence) Detective (in order to detect or identify occurrences) Deterrent (in order to discourage occurrences) Corrective (In order to correct or restore controls) Recovery (in order to restore resources, capabilities, or losses)

411: Which of the following is a facial feature identification product that can employ artificial intelligence and can require the system to learn from experience? A. All of the choices. B. Digital nervous system. C. Neural networking D. DSV

C Explanation: There are facial feature identification products that are on the market that use other technologies or methods to capture one's face. One type of method used is neural networking technology. This type of technology can employ artificial intelligence that requires the system to "learn" from experience. This "learning" experience helps the system to close in on an identification of an individual. Most facial feature identification systems today only allow for two-dimensional frontal images of one's face. Not DSV: Signature biometrics are often referred to dynamic signature verification (DSV) and look at the way we sign our names. [15] The dynamic nature differentiates it from the study of static signatures on paper. Within DSV a number of characteristics can be extracted from the physical signing process. Examples of these behavioral characteristics are the angle of the pen is held, the time taken to sign, velocity and acceleration of the tip of the pen, number of times the pen is lifted from the paper. Despite the fact that the way we sign is mostly learnt during the years it is very hard to forge and replicate.

637: The main categories of access control do NOT include: A. Administrative Access Control B. Logical Access Control C. Random Access Control D. Physical Access Control

C Explanation: There are several different categories of access control. The main categories are: --Physical Access Control --Administrative Access Control --Logical Access Control --Data Access Control

159: CISSP Actualtests.com - The Power of Knowing To ensure that integrity is attainted through the Clark and Wilson model, certain rules are needed.These rules are: A. Processing rules and enforcement rules. B. Integrity-bouncing rules. C. Certification rules and enforcement rules. D. Certification rules and general rules.

C Explanation: To ensure that integrity is attained and preserved, Clark and Wilson assert, certain integrity-monitoring and integrity-preserving rules are needed. Integrity-monitoring rules are called certification rules, and integrity-preserving rules are called enforcement rules.

289: Tokens, as a way to identify users are subject to what type of error? A. Token error B. Decrypt error C. Human error D. Encrypt error

C Explanation: Tokens are a fantastic way of ensuring the identity of a user. However, you must remember that no system is immune to "human error". If the token is lost with it's pin written on it, or if it were loaned with the corresponding pin it would allow for masquerading. This is one of the greatest threats that you have with tokens.

966: What type of attacks occurs when a rogue application has been planted on an unsuspecting user's workstation? A. Physical attacks B. Logical attacks C. Trojan Horse attacks D. Social Engineering attacks

C Explanation: Trojan Horse attacks - This attack involves a rogue, Trojan horse application that has been planted on an unsuspecting user's workstation. The Trojan horse waits until the user submits a valid PIN from a trusted application, thus enabling usage of the private key, and then asks the smartcard to digitally sign some rogue data. The operation completes but the user never knows that their private key was just used against their will.

315: What type of password makes use of two totally unrelated words? A. Login phrase B. One time password C. Composition D. Login ID

C Explanation: Usage of two totally unrelated words or a series of unrelated characters, such as pizza!wood for example. Such a password is easy to remember but very hard to guess. It would require a cracker quite a bit of time to do a brute force attack on a password that is that long and that uses an extended character as well.

396: Which of the following correctly describe DAC? A. It is the most secure method. B. It is of the B2 class. C. It can extend beyond limiting which subjects can gain what type of access to which objects. D. It is of the B1 class.

C Explanation: With DAC, administrators can limit access to certain times of day or days of the week. Typically, the period during which access would be permitted is 9 a.m. to 5 p.m. Monday through Friday. Such a limitation is designed to ensure that access takes place only when supervisory personnel are present, to discourage unauthorized use of data. Further, subjects' rights to access might be suspended when they are on vacation or leave of absence. When subjects leave an organization altogether, their rights must be terminated rather than merely suspended.

1315: What security model is dependant on security labels? A. Discretionary access control B. Label-based access control C. Mandatory access control D. Non-discretionary access control CISSP Actualtests.com - The Power of Knowing

C Explanation: With mandatory controls, only administrators and not owners of resources may make decisions that bear on or derive from policy. Only an administrator may change the category of a resource, and no one may grant a right of access that is explicitly forbidden in the access control policy. This kind of access control method is based on Security labels. It is important to note that mandatory controls are prohibitive (i.e., all that is not expressly permitted is forbidden).

401: With __________, access decisions are based on the roles that individual users have as part of an organization. A. Server based access control. B. Rule based access control. C. Role based access control. D. Token based access control.

C Explanation: With role-based access control, access decisions are based on the roles that individual users have as part of an organization. Users take on assigned roles (such as doctor, nurse, teller, manager). The process of defining roles should be based on a thorough analysis of how an organization operates and should include input from a wide spectrum of users in an organization.

402: Under Role based access control, access rights are grouped by: A. Policy name B. Rules C. Role name D. Sensitivity label

194: What control is based on a specific profile for each user? A. Lattice based access control. B. Directory based access control. C. Rule based access control. D. ID based access control.

C Explanation: With this model, information can be easily changed for only one user but this scheme may become a burden in a very large environment. A rule-based access control unit will intercept every request to the server and compare the source specific access conditions with the rights of the user in order to make an access decision. A good example could be a firewall. Here a set of rules defined by the network administrator is recorded in a file. Every time a connection is attempted (incoming or outgoing), the firewall software checks the rules file to see if the connection is allowed. If it is not, the firewall closes the connection. CISSP Actualtests.com - The Power of Knowing

1170: CISSP Actualtests.com - The Power of Knowing What type of cable is used with 100Base-TX Fast Ethernet? A. Fiber-optic cable B. Four pairs of Category 3, 4 or 5 unshielded twisted-par (UTP) wires. C. Two pairs of Category 5 unshielded twisted-pair (UTP) or Category 1 shielded twisted-pair (STP) wires. D. RG.58 cable.

C Explanation: 100BaseTX is a 100-Mbps baseband Fast Ethernet specification using two pairs of either UTP or STP wiring. The first pair of wires is used to receive data; the second is used to transmit. To guarantee proper signal timing, a 100BaseTX segment cannot exceed 100 meters in length. This specification of Ethernet is based on the IEEE 802.3 standard.

1177: A password that is the same for each log-on session is called a? A. "one-time password" B. "two-time password" C. static password D. dynamic password

C Explanation: A Static password is one that remains the same until its changed. Its like the password that we use in the operating systems, you set it, and then you always use the same password to logon to the system for the time of the session. This password will give us access to the system and will be the vehicle to create our access token in a successful way to get our privileges. A one-time password is only valid for one use, dynamic ones change every certain condition is met, and two-time passwords can only be used two times. We can provide certain times of access with this kind of passwords. CISSP Actualtests.com - The Power of Knowing

1234: An offsite backup facility intended to operate an information processing facility, having no computer or communications equipment, but having flooring, electrical writing, air conditioning, etc. Is better known as a? A. Hot site B. Duplicate processing facility C. Cold site D. Warm site

C Explanation: A cold site has all the appropriate power requirements, and floor space to install the hardware and to enable you to recreate your computer environment, but does not provide the actual equipment. Many of the companies that provide hot sites also provide cold sites. It may be reasonable for your company to consider creating its won cold site if your company has floor space available in another location than the home site. They require much more outage than Hot sites before operations can be restored.

1227: A prolonged high voltage is? A. Spike B. Blackout C. Surge D. Fault

C Explanation: A surge is a prolonged spike, it occur when the power level rises above normal levels and then drop back to normal in less than one second. A Spike occurs when the power level rises above normal levels and stays there for more than 1 or 2 seconds.. A blackout is the total loss of power and a fault is the opposite of a Spike, it's a lowering in the voltage, its usually around one second. The surge is the most dangerous from the listed above.

1299: Which of the following questions should any user not be able to answer regarding their organization information security policy? A. Who is involved in establishing the security policy? B. Where is the organization security policy defined? C. What are the actions that need to be performed in case of a disaster? D. Who is responsible for monitoring compliance to the organization security policy?

C Explanation: According to CISSP documentation, the actual definition and procedures defined inside an organization disaster recovery policy are of private nature. Only people working in the company and with a role inside it should know about those procedures. Its not a good practice to be divulgating Disaster recovery procedures to external people. Many times external people need to know who is involved in it, and who is responsible. This could be the case of a vendor providing replacement equipment in case of disaster.

1200: According to private sector data classification levels, how would salary levels and medical information be classified? A. Public B. Sensitive C. Private D. Confidential

C Explanation: According to the classification levels of the private sector, this information is classified as Private because this information is from a personal nature. There is no need for other employees to see details about your health or you salary range, this can lead to internal problems inside the company, problems like jealous employees.

1276: Which of the following embodies all the detailed actions that personnel are required to follow? A. Standards B. Guidelines C. Procedures D. Baselines

C Explanation: As stated in the dictionary, here are 3 definitions of procedure: 1. A manner of proceeding; a way of performing or effecting something: standard procedure. 2. A series od steps taken to accomplish an end: a medical procedure; evacuation procedures. 3. A set of established forms or methods for conducting the affairs of an organized body such as a business, club, or government. Its pretty visible that this is the term we are looking for as stated in the questions, you can check your CISSP documentation too.

123: A feature deliberately implemented in an operating system as a trap for intruders is called a: A. Trap door B. Trojan horse C. Pseudo flaw D. Logic bomb

C "An apparent loophole deliberately implanted in an operating system program as a trap for intruders." As defined by the Aqua Book NCSC-TG-004 a pseudo-flaw is an apparent loophole deliberately implanted in an operating system program as a trap for intruders. Answer from http://www.cccure.org

1286: What are suitable protocols for securing VPN connections? A. S/MIME and SSH B. TLS and SSL C. IPsec and L2TP D. PKCS# and X.509

C Explanation: Both of them can be used to create and secure VPN's. The Layer 2 Tunnel Protocol (L2TP) is an emerging Internet Engineering Task Force (IETF) standard that combines the best features of two existing tunneling protocols: Cisco's Layer 2 Forwarding (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP). L2TP is an extension to the Point-to-Point Protocol (PPP), which is an important component for VPNs. VPNs allow users and telecommuters to connect to their corporate intranets or extranets. IPSec is a series of guidelines for the protection of Internet Protocol (IP) communications. It specifies ways for securing private information transmitted over public networks. Services supported by IPSec include confidentiality (encryption), authenticity (proof of sender), integrity (detection of data tampering) and replay protection (defense against unauthorized re-sending of data). It work on layer 3 of the OSI model and is the most common protocols used to create VPNs.

1156: Which of the following can be used to raise awareness of the importance of security and risk? A. Money B. All of the above C. None of the above

C Explanation: C is the only logical choice. Awareness and the importance of security and risk can not be improved or awareness be increased with only money. Awareness is produced by providing employees with education and training. Reference the Training and Education Triad. Exam Cram 2 CISSP Page 52

1335: Which DES modes can best be used for authentication? A. Cipher Block Chaining and Electronic Code Book. B. Cipher Block Chaining and Output Feedback. C. Cipher Block Chaining and Cipher Feedback. D. Output Feedback and Electronic Code Book.

C Explanation: Cipher Block Chaining (CBC) uses feedback to feed the result of encryption back into the encryption of the next block. The plain-text is XOR'ed with the previous cipher-text block before it is encrypted. The encryption of each block depends on all the previous blocks. This requires that the decryption side processes all encrypted blocks sequentially. This mode requires a random initialization vector which is XOR'ed with the first data block before it is encrypted. The initialization vector does not have to be kept secret. The initialization vector should be a random number (or a serial number), to ensure that each message is encrypted uniquely. In the Cipher Feedback Mode (CFB) is data encrypted in units smaller than the block size. This mode can be used to encrypt any number of bits e.g. single bits or single characters (bytes) before sending across an insecure data link. Both of those method can be best used to provide user authentication capabilities.

1361: Which of the following is not considered firewall technology? A. Screened subnet B. Screened host C. Duel gateway host D. Dual homed host

C Explanation: Duel gateway host is not considered firewall technology.

1283: In IPSec, if the communication mode is gateway-gateway or host-gateway: A. Only tunnel mode can be used. B. Only transport mode can be used. CISSP Actualtests.com - The Power of Knowing C. Encapsulating Security Payload (ESP) authentication must be used. D. Both tunnel and transport mode can be used.

C Explanation: ESP or Encrypted Security Payload, is a header that when its added to an IP datagram, protects the confidentiality, integrity and authenticity of the data. AH and ESP can be used separately or together. As defined by the IETF, IPSec transport mode can only be used when both the source and destination systems understand IPSEC. In most cases you deploy IPSEC in tunnel mode. In this transport mode (gateway to gateway and gateway to host) you must use ESP for authentication.

1195: What is the proper term to refer to a single unit of Ethernet data? A. Ethernet segment B. Ethernet datagram C. Ethernet frame D. Ethernet packet

C Explanation: Ethernet traffic is transported in units of a frame, where each frame has a definite beginning and end. Here is an Ethernet frame: CISSP Actualtests.com - The Power of Knowing In this picture we define: 1. Preamble Field used for synchronization, 64-bits 2. Destination Address Ethernet address of the destination host, 48-bits 3. Source Address Ethernet address of the source host, 48-bits 4. Type of data encapsulated, e.g. IP, ARP, RARP, etc, 16-bits. 5. Data Field Data area, 46-1500 bytes, which has Destination Address Internet address of destination host Source Address Internet address of source host 6. CRC Cyclical Redundancy Check, used for error detection

1235: Which of the following are necessary components of a Multi-Level Security Policy? A. Sensitivity Labels and a "system high" evaluation. B. Sensitivity Labels and Discretionary Access Control. C. Sensitivity Labels and Mandatory Access Control. D. Object Labels and a "system high" evaluation.

C Explanation: First implemented in Military organizations (and I think even today it's implemented there only), this model was a significant improvement in terms of security policy implementation. This model made implementation of complex security policies very CISSP Actualtests.com - The Power of Knowing simple. It's specifications are present in the orange book from DoD. In this model, every object is assigned a sensitivity label. Also, every user is assigned a sensitivity label. If a user's sensitivity label is greater than or equal to the sensitivity label, he is allowed access to the object, otherwise, he is denied access. This methodology is used for creating a hierarchy of access. We can say that this method is used for partitioning the organization hierarchy horizontally. Multi-Level Security is considered a Mandatory Access Control method.

1179: Which of the following is not a weakness of symmetric cryptography? A. Limited security B. Key distribution C. Speed D. Scalability

C Explanation: In secret key cryptography, a single key is used for both encryption and decryption. The sender uses the key (or some set of rules) to encrypt the plaintext and sends the cipher text to the receiver. The receiver applies the same key (or rule set) to decrypt the message and recover the plaintext. Because a single key is used for both functions, secret key cryptography is also called symmetric encryption. With this form of cryptography, it is obvious that the key must be known to both the sender and the receiver ; that in fact, is the secret. The biggest difficulty with this approach, of course, is the distribution of the key. Symmetric encryption is around 1000 times faster than Asymmetric encryption, the second is commonly used just to encrypt the keys for Symmetric Cryptography.

1349: Job rotation is important because: A. It insures your employees are cross-trained. B. It increases job satisfaction. C. It reduces the opportunity for fraud

C Explanation: Job rotation is tightly tied to the principle of least privilege. It is an effective security control.

1237: Which of the following is addressed by Kerberos? A. Authorization and authentication. B. Validation and integrity. C. Confidentiality and integrity.

C Explanation: Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology. Kerberos is available in many commercial products as well. Kerberos was created by MIT as a solution to these network security problems. The Kerberos protocol uses strong cryptography so that a client can prove its identity to a server (and vice versa) across an insecure network connection. After a client and server has used Kerberos to CISSP Actualtests.com - The Power of Knowing prove their identity, they can also encrypt (confidentiality) all of their communications to assure privacy and data integrity as they go about their business.

1310: Which of the following firewall rules is less likely to be found on a firewall installed between and organization internal network and the Internet? A. Permit all traffic to and from local host. B. Permit all inbound ssh traffic C. Permit all inbound tcp connections. D. Permit all syslog traffic to log-server.abc.org.

C Explanation: Option "C" is a very bad practice in a firewall connecting one of its interfaces to a public network like Internet. Since in that rule you are allowing all inbound TCP traffic, the hackers can send all the attacks they want to any TCP port, they can make port scanning, Syn Attacks, and many other dangerous DoS activities to our private network. Permit the traffic from local host is a best practice, our firewall is the local host. Permit SSH (Secure Shell) is also good because this protocol use cryptography.

1226: Which of the following layers of the ISO/OSI model do packet filtering firewalls operate at? A. Application layer B. Session layer C. Network layer D. Presentation layer

C Explanation: Packet filtering firewalls work at the network level of the OSI model, or the IP layer of TCP/IP. These firewalls are normally part of a router, which is a device that receives and forwards packets to networks. "In a packet filtering firewall each packet is CISSP Actualtests.com - The Power of Knowing compared to a set of criteria before it is forwarded. Depending on the packet and the criteria, the firewall can drop the packet, forward it, or send a message to the originator." The criteria used to evaluate a packet include source, destination IP address, destination port, and protocol used. These types of firewalls are low in cost and don't have much of an impact on the network's performance.

1320: Which type of control is concerned with avoiding occurrences of risks? A. Deterrent controls B. Detective controls C. Preventive controls CISSP Actualtests.com - The Power of Knowing D. Compensating controls

C Explanation: Preventive controls deals with the avoidance of risk through the diminution of probabilities. Is like the example we read earlier about the dogs. Just to remember, Since we want to prevent something from happening, we can go out and buy some Guard dogs to make the job. You are buying them because you want to prevent something from happening. The intruder will see the dogs and will maybe go back, this prevents an attack, this dogs are a form of preventive control.

538: Which one of the following is NOT a characteristic of an Intrusion Detection System? (IDS) A. Determines the source of incoming packets. B. Detects intruders attempting unauthorized activities. C. Recognizes and report alterations to data files. D. Alerts to known intrusion patterns.

C Explanation: Software employed to monitor and detect possible attacks and behaviors that CISSP Actualtests.com - The Power of Knowing vary from the normal and expected activity. The IDS can be network-based, which monitors network traffic, or host-based, which monitors activities of a specific system and protects system files and control mechanisms. - Shon Harris All-in-one CISSP Certification Guide pg 932

1324: By examining the "state" and "context" of the incoming data packets, it helps to track the protocols that are considered "connectionless", such as UDP-based applications and Remote Procedure Calls (RPC). This type of firewall system is used in? A. First generation firewall systems. B. Second generation firewall systems. C. Third generation firewall systems. D. Fourth generation firewall systems.

C Explanation: Statefull inspection is a third generation firewall technology designed to be aware of, and inspect, not only the information being received, but the dynamic connection and transmission state of the information being received. Control decisions are made by analyzing and utilizing the following: Communication Information, Communication derived state, Application derived state and information manipulation. Here are some characteristics of Statefull Inspection technology on Firewalls: CISSP Actualtests.com - The Power of Knowing 1. Scan information from all layers in the packet. 2. Save state information derived from previous communications, such as the outgoing Port command of an FTP session, so that incoming data communication can be verified against it. 3. Provides tracking support for connectionless protocols through the use of session state databases. 4. Allow state information derived from other applications access through the firewall for authorized services only, such as previously authenticated users. 5. Evaluate and manipulate flexible expressions based on communication and application derived state information.

1360: Which of the following is a connection-orientated protocol? A. IP B. UDP C. TCP D. ICMP E. SNMP F. TFTP

C Explanation: TCP is a connection-orientated protocol.

1281: Controls are implemented to? A. Eliminate risk and reduce the potential for loss. B. Mitigate risk and eliminate the potential for loss. C. Mitigate risk and reduce the potential for loss. D. Eliminate risk and eliminate the potential for loss.

C Explanation: That's the essence of Controls, you put them in your environment to minimize the impact of a potential loss, with them you can also mitigate the risk and obtain the first through this. Controls are a very good practice to secure an environment, they should be considered by any security professional, CISSP or not, the risk should be minimized as much as you can.

823: Which of the following statements pertaining to Asynchronous Transfer Mode (ATM) is false? A.) It can be used for voice B.) It can be used for data C.) It carries various sizes of packets D.) It can be used for video

C "Asynchronous transfer mode (ATM) is a cell-switching technology, as opposed to a packet-switching technology like Frame Relay. ATM uses virtual circuits much like Frame Relay, but because it uses fixed-size frames or cells, it can guarantee throughput. This makes ATM an excellent WAN technology for voice and video conferencing." Pg 87 Tittel: CISSP Study Guide CISSP Actualtests.com - The Power of Knowing

1193: Which model, based on the premise that the quality of a software product is a direct function of the quality of its associated software development and maintenance processes, introduced five levels with which the maturity of an organization involved in the software process is evaluated? A. The Total Quality Model (TQM) B. The IDEAL Model C. The Software Capability Maturity Model D. The Spiral Model

C Explanation: The Capability Maturity Model for Software describes the principles and practices underlying software process maturity and is intended to help software organizations improve the maturity of their software processes in terms of an evolutionary path from ad hoc, chaotic processes to mature, disciplined software processes. The CMM is organized into five maturity levels:1) Initial. The software process is characterized as ad hoc, and occasionally even chaotic. Few processes are defined, and success depends on individual effort and heroics.2) Repeatable. Basic project management processes are established to track cost, schedule, and functionality. The necessary process discipline is in place to repeat earlier successes on projects with similar applications.3)Defined. The software process for both management and engineering activities is documented, standardized, and integrated into a standard software process for the organization. All projects use an approved, tailored version of the organization's standard software process for developing and maintaining software.4) Managed. Detailed measures of the software process and product quality are collected. Both the software process and products are quantitatively understood and controlled.5) Optimizing. Continuous process improvement CISSP Actualtests.com - The Power of Knowing is enabled by quantitative feedback from the process and from piloting innovative ideas and technologies.

1284: Which integrity model defines a constrained data item, an integrity verification procedure and a transformation procedure? A. The Take-Grant model B. The Biba integrity model C. The Clark Wilson integrity model D. The Bell-LaPadula integrity model

C Explanation: The Clark-Wilson model was developed to address security issues in commercial environments. The model uses two categories of mechanisms to realize integrity: well-formed transactions and separation of duty. It defines a constraint data item, a integrity verification and a transformation of that object. A possible way to represent a constraint that only certain trusted programs can modify objects is using application:checksum condition, where the checksum ensures authenticity of the application. Another way is using application:endorser condition, which indicates that a valid certificate, stating that the application has been endorsed by the specified endorser, must be presented. Static separation of duty is enforced by the security administrator when assigning group membership. Dynamic separation of duty enforces control over how permissions are used at the access time

1163: Which DES mode of operation is best suited for database encryption? A. Cipher Block Chaining (CBC) mode B. Cycling Redundancy Checking (CRC) mode C. Electronic Code Book (ECB) mode D. Cipher Feedback (CFB) mode

C Explanation: The DES algorithm in Electronic Codebook (ECB) mode is used for DEK and MIC encryption when symmetric key management is employed. The character string "DES-ECB" within an encapsulated PEM header field indicates use of this algorithm/mode combination. A compliant PEM implementation supporting symmetric key management shall support this algorithm/mode combination. This mode of DES encryption is the best suited for database encryption because of its low overhead. ECB Mode has some weakness, here they are: 1. ECB Mode encrypts a 64-bit block independently of all other 64-bit blocks 2. Given the same key, identical plaintext will encrypt the same way 3. Data compression prior to ECB can help (as with any mode) 4. Fixed block size of 64 bits therefore incomplete block must be padded

1218: Which of the following statements pertaining to VPN protocol standards is false? A. L2TP is a combination of PPTP and L2F. B. L2TP and PPTP were designed for single point-to-point client to server communication. C. L2TP operates at the network layer. D. PPTP uses native PPP authentication and encryption services.

C Explanation: The Layer 2 Tunnel Protocol (L2TP) is an emerging Internet Engineering Task Force (IETF) standard that combines the best features of two existing tunneling protocols: Cisco's Layer 2 Forwarding (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP). L2TP is an extension to the Point-to-Point Protocol (PPP), which is an important component for VPNs. VPNs allow users and telecommuters to connect to their corporate intranets or extranets. VPNs are cost-effective because users can connect to the Internet locally and tunnel back to connect to corporate resources. This not only reduces overhead costs associated with traditional remote access methods, but also improves flexibility and scalability. PPTP and L2TP are Layer 2 tunneling protocols; both encapsulate the payload in a Point-to-Point Protocol (PPP) frame to be sent across an intermediate network.

1219: What is the most critical characteristic of a biometric identifying system? A. Perceived intrusiveness B. Storage requirements C. Accuracy D. Reliability

C Explanation: The principle of biometrics is to use some unique characteristic to identify whether the person is who they say they are. Biometrics works by matching or verifying a person's unique traits with stored data in two categories: physiological characteristics and those that are behavioral. Physical indicators include iris, fingerprint, facial, or hand geometry. Behavior types are usually voiceprints, keystroke dynamics and handwritten signatures. Most biometric technologies require special hardware to convert analog CISSP Actualtests.com - The Power of Knowing measurements of signatures, voices, or patterns of fingerprints and palm prints, to digital measurement, which computers can read. The biggest characteristic and problem of biometric implementations today is the accuracy, we must see the level of accuracy before buying a solution, because the technology is not perfect at this time and it can be erroneous sometimes.

1183: What are database views used for? A. To ensure referential integrity. B. To allow easier access to data in a database. C. To restrict user access to data in a database. D. To provide audit trails. CISSP Actualtests.com - The Power of Knowing

C Explanation: Through the use of a view we can provide security for the organization restricting users access to certain data or to the real tables containing the information in our database. For example, we can create a view that brings data from 3 tables, only showing 2 of the 4 columns in each. Instead of giving access to the tables that contain the information, we give access to the view, so the user can access this fixed information but does not have privileges over the tables containing it. This provides security.

1296: The following is not true: A. Since the early days of mankind humans have struggled with the problems of protecting assets. B. The addition of a PIN keypad to the card reader was a solution to unreported card or lost card problem. C. There has never been of problem of lost keys. D. Human guard is an inefficient and sometimes ineffective method of protecting resources.

C Explanation: This is absolutely false, this problem can be seen almost anywhere. There have always been trouble with the lost of keys. Some of those looses are more important than others, its not the same to lost the key of the company safe box, that lost the key of you locker with that contains your shoes. This is obviously an incorrect statement, answer C is the one in here. "Unfortunately, using security guards is not a perfect solution. There are numerous disadvantages to deploying, maintaining, and relying upon security guards. Not all environments and facilities support security guards. This may be due actual human incompatibility with the layout, design, location, and construction of the facility. Not all security guards are themselves reliable. Prescreening, bonding, and training does not guarantee that you won't end up with an ineffective and unreliable security guard." Pg 646 Tittel: CISSP Guide.

1297: Which of the following statements pertaining to software testing approaches is correct? A. A bottom-up approach allows interface errors to be detected earlier. B. A top-down approach allows errors in critical modules to be detected earlier. C. The test plan and results should be retained as part of the system's permanent documentation. D. Black box testing is predicted on a close examination of procedural detail. CISSP Actualtests.com - The Power of Knowing

C Explanation: This is an absolute best practice in the software testing field, you should always have to keep all your testing approaches with the results as part of the product documentation. This can help you in the case you have problems with some tasks or components of the software in the future, you can check back your testing and results and see if the system was making the tasks correctly and if anything changed from that environment.

1302: Which of the following items should not be retained in an E-mail directory? A. Drafts of documents. B. Copies of documents. C. Permanent records. D. Temporary documents.

C Explanation: This is another matter of common sense, the CISSP exam has many situations like this. Its not a good practice to have Permanent documents in your e-mail, this is because you don't know if your -mail is always backed up, and maybe the document must be available in a corporate repository. There is not problem to have Copies, draft or temporary documents in your e-mail. The important ones for the company are the Permanent documents. CISSP Actualtests.com - The Power of Knowing

1334: Which of the following statements pertaining to the (ISC)2 Code of Ethics is incorrect? CISSP Actualtests.com - The Power of Knowing A.

All information systems security professionals who are certified by (ISC)2 shall discourage such behavior as associating or preparing to associate with criminals or criminal behavior. D. All information systems security professionals who are certified by (ISC)2 shall promote the understanding and acceptance of prudent information security measures.

C Explanation: This is not one of the statements of the ISC2 code of Ethics, ISC2 certified people is free to get in association with any person and any party they want. ISC2 thinks that their certified people must have liberty of choice in their associations. However ISC2 ask the certified professionals to promote the certification and the understanding and acceptance of security measures, they also ask the certified people to provide competent services and be proud of their exclusive ISC2 certified professional status. I think is very fair, you are free to who where you want, with the people you want, but always be proud of your certification and your skills as a security professional. Code from ISC web site. "All information systems security professionals who are certified by (ISC)2 recognize that such certification is a privilege that must be both earned and maintained. In support of this principle, all Certified Information Systems Security Professionals (CISSPs) commit to fully support this Code of Ethics. CISSPs who intentionally or knowingly violate any provision of the Code will be subject to action by a peer review panel, which may result in the revocation of certification. There are only four mandatory canons in the code. By necessity such high-level guidance is not intended to substitute for the ethical judgment of the professional. Additional guidance is provided for each of the canons. While this guidance may be considered by the Board in judging behavior, it is advisory rather than mandatory. It is intended to help the professional in identifying and resolving the inevitable ethical dilemmas that will confront him/her. Code of Ethics Preamble: * Safety of the commonwealth, duty to our principals, and to each other requires that we adhere, and be seen to adhere, to the highest ethical standards of behavior. * Therefore, strict adherence to this code is a condition of certification. Code of Ethics Canons: * Protect society, the commonwealth, and the infrastructure. * Act honorably, honestly, justly, responsibly, and legally. * Provide diligent and competent service to principals. * Advance and protect the profession.

1174: Due are is not related to: A. Good faith B. Prudent man C. Profit D. Best interest

C Explanation: This is obviously a term not related to Profit, a "due" is not going to give us profit, its going to give us the opposite. Its always a good practice to pay your due. This can be learned in the real life. A Prudent man always pays its due, also a Good faith men pays them. This term is not related to profit.

1250: In an organization, an Information Technology security function should: A. Be a function within the information systems function of an organization. B. Report directly to a specialized business unit such as legal, corporate security or insurance. CISSP Actualtests.com - The Power of Knowing C. Be lead by a Chief Security Officer and report directly to the CEO. D. Be independent but report to the Information Systems function.

C Explanation: This is one of the best practices because its not good to be lead and report to the same person, in that case, that person could take possession of everything that is happening and hurt the enterprise, we can't let that to happen with security concerns. The best practice is to always be lead by a different person that the one you report to, this can be checked in real life. An advice, always try to report to the highest person you can inside the company.

1269: In order to ensure the privacy and integrity of the data, connections between firewalls over public networks should use? A. Screened subnets B. Digital certificates C. Encrypted Virtual Private Networks D. Encryption

C Explanation: This is the correct answer, since firewall does not mean "VPN" we have to select "Encrypted Virtual Private Networks". With a VPN and encryption we can provide secure communication in a transparent way for the users between the endpoints achieving "Confidentiality". This confidentiality is achieved through encryption, and this encryption relies on encryption algorithms like AES, DES, CAST and others. Screened Subnet are not related to secure data over public networks, it's a place to put our network services accessible from the outside. Digital certificates do not provide confidentiality, they only provide integrity.

1251: Who of the following is responsible for ensuring that proper controls are in place to address integrity, confidentiality, and availability of IT systems and data? A. Business and functional managers. B. IT Security practitioners. C. System and information owners. D. Chief information officer.

C Explanation: This is true, the people who own the information and the equipment are the ones who need to ensure they are making everything to get integrity, confidentiality and availability. The security professionals can develop policies and show how to keep the environment secure, but it depends on the owners of the actual data to achieve the security.

1314: Which of the following should not be performed by an operator? A. Mounting disk or tape B. Backup and recovery C. Data entry D. Handling hardware

C Explanation: This is very obvious, the operators are responsible of making operative tasks that deals with the hardware and software implementations, they can handle the hardware and put t in condition for the user, be in charge of the backup and restore procedures and Mounting the disk or tapes for the backup. Those are all common tasks. When we talk about the data entry, is the user who has to make does, If the operator do that too, what is the user going to do?

C A security kernel is defined as the hardware, firmware, and software elements of a trusted computing base that implements the reference monitor concept. A reference monitor is a system component that enforces access controls on an object. Therefore, the reference monitor concept is an abstract machine that mediates all access of subjects to objects. The Security Kernel must: Mediate all accesses Be protected from modification Be verified as correct. -Ronald Krutz The CISSP PREP Guide (gold edition) pg 262

623: Which of the following are functions that are compatible in a properly segregated environment? A.) Application programming and computer operation B.) Systems programming and job control analysis C.) Access authorization and database administration D.) System development and systems maintenance

C Access Authorization and Database Administration are the most similar tasks of all the choices CISSP Actualtests.com - The Power of Knowing so they need not be separated. Administrative Management: Administratative management is a very important piece of operational security. One aspect of administrative management is dealing with personnel issues. This includes separation of duties and job rotation. The objective of separation of duties is to ensure that one person acting alone cannot compromise the company's security in any way. High-risk activities should be broken up into different parts and distributed to different individuals. This way the company does not need to put a dangerously high level of trust on certain individuals and if fraud were to take place, collusion would need to be committed, meaning more than one person would have to be involved in the fraudulent activity. Separation of duties also helps to prevent many different types of mistakes that can take place if one person is performing a task from the beginning to the end. For instance, a programmer should not be the one to test her own code. A different person with a different job and agenda should perform functionality and integrity testing on the programmer's code because the programmer may have a focused view of what the program is supposed to accomplish and only test certain functions, input values, and in certain environments. Another example of separation of duties is the difference between the functions of a computer operator versus the functions of a system administrator. There must be clear cut lines drawn between system administrator duties and computer operator duties. This will vary from environment to environment and will depend on the level of security required within the environment. The system administrators usually have responsibility of performing backups and recovery procedures, setting permissions, adding and removing users, setting user clearance, and developing user profiles. The computer operator on the other hand, may be allowed to install software, set an initial password, alter desktop configurations, and modify certain system parameters. The computer operator should not be able to modify her own security profile, add and remove users globally, or set user security clearance. This would breach the concept of separation of duties.

814: Which type of attack is based on the probability of two different messages using the same hash function producing a common message digest? CISSP Actualtests.com - The Power of Knowing A.) Differential cryptanalysis B.) Differential linear cryptanalysis C.) Birthday attack D.) Statistical attack

C Attacks Against One-Way Hash Functions: A good hashing algorithm should not produce the same hash value for two different messages. If the algorithm does produce the same value for two distinctly different messages, this is referred to as a collision. If an attacker finds an instance of a collision, he has more information to use when trying to break the cryptographic methods used. A complex way of attacking a one-way hash function is called the birthday attack. Now hold on to your had while we go through this -- it is a bit tricky. In standard statistics, a birthday paradox exists. It goes something like this: How many people must be in the same room for the chance to be greater than even that another person has the same birthday as you? Answer: 253 How many people must be in the same room for the chance to be greater than even that at least two people share the same birthday? Answer: 23 This seems a bit backwards, but the difference is that in the first instance, you are looking for someone with a specific birthday date, which matches yours. In the second instance, you are looking for any two people who share the same birthday. There is a higher probability of finding two people who share a birthday than you finding another person sharing your birthday -- thus, the birthday paradox. ....This means that if an attacker has one hash value and wants to find a message that hashes to the same hash value, this process could take him years. However, if he just wants to find any two messages with the same hashing value, it could take him only a couple hours. .....The main point of this paradox and this section is to show how important longer hashing values truly are. A hashing algorithm that has a larger bit output is stronger and less vulnerable to brute force attacks like a birthday attack. Pg 554-555 Shon Harris: All-In-One Certification Exam Guide

1331: Which of the following is responsible for the most security issues? A. Outside espionage B. Hackers C. Personnel D. Equipment failure

C CISSP Actualtests.com - The Power of Knowing Explanation: As I stated earlier in the comments, the great part of the attacks to companies comes from the personnel. Hackers are out there and attack some targets, but should never forget that your worst enemy can be inside of your company. Is for that that we usually implement IDS and profundity security. It's a very good practice to install Host based IDS to limit the ability of internal attackers through the machines. Another problem with personal is the ignorance, there are time that they just don't know what they are doing, and certainly are violating the security policy.

915: Which one of the following operations of a secure communication session cannot be protected? A. Session initialization B. Session support C. Session termination D. Session control

C I did not find the answer to this question in any of the texts sources I read for the cissp. However, Network Intrusion Detection (3rd edition) gives some hints. I am basing this off of the 3 way hand shake and looking for the termination of the session and who does it. Was it a RESET or FIN in the packet. So based off this concept I am concluding that Session Termination is really not controllable. Use your best judgment on this question based off of experience and knowledge.

107: What is a PRIMARY reason for designing the security kernel to be as small as possible? A. The operating system cannot be easily penetrated by users. B. Changes to the kernel are not required as frequently. C. Due to its compactness, the kernel is easier to formally verify. D. System performance and execution are enhanced.

C I disagree with the original answer which was B (changes to the kernel) and think it is C (Due to its compactness). However, use your best judgment based on knowledge and experience. Below is why I think it is C. CISSP Actualtests.com - The Power of Knowing "There are three main requirements of the security kernel: It must provide isolation for the processes carrying out the reference monitor concept and they must be tamperproof. The reference monitor must be invoked for every access attempt and must be impossible to circumvent. Thus the reference monitor must be implemented in a complete and foolproof way. à It must be small enough to be able to be tested and verified in a complete and comprehensive manner." - Shon Harris All-in-one CISSP Certification Guide pg 232-233

475: The PRIMARY purpose of operations security is A. Protect the system hardware from environment damage. B. Monitor the actions of vendor service personnel. C. Safeguard information assets that are resident in the system. D. Establish thresholds for violation detection and logging.

543: IDS can be described in terms of what fundamental functional components? A. Response B. Information Sources C. Analysis D. All of the choices.

D Explanation: Many IDSs can be described in terms of three fundamental functional components: Information Sources - the different sources of event information used to determine whether an intrusion has taken place. These sources can be drawn from different levels of the system, with network, host, and application monitoring most common. Analysis - the part of intrusion detection systems that actually organizes and makes sense of the events derived from the information sources, deciding when those events indicate that intrusions are occurring or have already taken place. The most common analysis approaches are misuse detection and anomaly detection. Response - the set of actions that the system takes once it detects intrusions. These are typically grouped into active and passive measures, with active measures involving some automated intervention on the part of the system, and passive measures involving reporting IDS findings to humans, who are then expected to take action based on those reports.

292: Which of the following is a disadvantage of a memory only card? A. High cost to develop. B. High cost to operate. C. Physically infeasible. D. Easy to counterfeit.

D Explanation: Memory Only Card - This type of card is the most common card. It has a magnetic stripe on the back. These cards can offer two-factor authentication, the card itself (something you have) and the PIN (something you know). Everyone is familiar with the use of an ATM (Automated Teller Machine) card. These memory cards are very easy to counterfeit. There was a case in Montreal where a storeowner would swipe the card through for the transaction; he hould then swipe it through a card reader to get a copy, while a small hidden camera was registering the PIN as the user was punching it on the pad. This scheme was quickly identified as the victims had one point in common; they all visited the same store.

26: Most computer attacks result in violation of which of the following security properties? A. Availability B. Confidentiality C. Integrity and control D. All of the choices.

D Explanation: Most computer attacks only corrupt a system's security in very specific ways. For example, certain attacks may enable a hacker to read specific files but don't allow alteration of any system components. Another attack may allow a hacker to shut down certain system components but doesn't allow access to any files. Despite the varied capabilities of computer attacks, they usually result in violation of only four different security properties: availability, confidentiality, integrity, and control.

553: Which of the following are the major categories of IDSs response options? A. Active responses B. Passive responses C. Hybrid D. All of the choices.

D Explanation: Once IDSs have obtained event information and analyzed it to find symptoms of attacks, they generate responses. Some of these responses involve reporting results and findings to a pre-specified location. Others involve more active automated responses. Though CISSP Actualtests.com - The Power of Knowing researchers are tempted to underrate the importance of good response functions in IDSs, they are actually very important. Commercial IDSs support a wide range of response options, often categorized as active responses, passive responses, or some mixture of the two.

644: ___________________ are the technical ways of restricting who or what can access system resources. A. Preventive Manual Controls B. Detective Technical Controls C. Preventive Circuit Controls D. Preventive Technical Controls

962: What attack floods networks with broadcast traffic so that the network is congested? A. Spoofing B. Teardrop C. Brute force CISSP Actualtests.com - The Power of Knowing D. SMURF

D Explanation: SMURF attack -- This attack floods networks with broadcast traffic so that the network is congested. The perpetrator sends a large number of spoofed ICMP (Internet Control Message Protocol) echo requests to broadcast addresses hoping packets will be sent to the spoofed addresses. You need to understand the OSI model and how protocols are transferred between layer 3 and layer 2 to understand this attack. The layer 2 will respond to the ICMP echo request with an ICMP echo reply each time, multiplying the traffic by the number of hosts involved. Engineers should turn off broadcast capability (if possible in your environment) to deter this kind of attack.

1191: What are two types of system assurance? A. Operational Assurance and Architecture Assurance. B. Design Assurance and Implementation Assurance. C. Architecture Assurance and Implementation Assurance. D. Operational Assurance and Life-Cycle Assurance.

D Explanation: Software Systems Quality Assurance (SQA) is defined as a planned and systematic approach to the evaluation of the quality of and adherence to software product standards, processes, andprocedures. SQA includes the process of assuring that standards and procedures are established and are followed throughout the software acquisition life cycle. Compliance with agreed-upon standards and procedures is evaluated through process monitoring, product evaluation, and audits. Software development and control processes should include quality assurance approval points, where an SQA evaluation of the product may be done in relation to the applicable standards. The 2 types available are : Operational assurance (that specified that the operation compiles with the required) and Life-Cycle assurance (that specifies that the system has passed through all the Software life-cycle).

408: Which of the following RFC talks about Rule Based Security Policy? A. 1316 B. 1989 C. 2717 D. 2828

D Explanation: The RFC 2828 - Internet Security Glossary talks about Rule Based Security Policy: A security policy based on global rules imposed for all users. These rules usually rely on comparison of the sensitivity of the resource being accessed and the possession of corresponding attributes of users, a group of users, or entities acting on behalf of users.

577: Which of the following should NOT be logged for performance problems? A. CPU load. B. Percentage of use. C. Percentage of idle time. D. None of the choices.

D Explanation: The level of logging will be according to your company requirements. Below is a list of items that could be logged, please note that some of the items may not be applicable to all operating systems. What is being logged depends on whether you are looking for performance problems or security problems. However you have to be careful about performance problems that could affect your security.

273: In terms of the order of acceptance, which of the following technologies is the LEAST accepted? A. Fingerprint B. Iris C. Handprint D. Retina patterns

D Explanation: The order of acceptance has slightly changed in the past years. It was Iris that was the most accepted method three years ago but today we have Voice Pattern that is by far the most accepted. Here is the list from most accepted first to least accepted at the bottom of the list: Voice Pattern Keystroke pattern Signature Hand geometry Handprint Fingerprint Iris Retina pattern

866: What protocol was UDP based and mainly intended to provide validation of dial up user login passwords? A. PPTP B. L2TP C. IPSec D. TACACS

D Explanation: The original TACACS protocol was developed by BBN for MILNET. It was UDP based and mainly intended to provide validation of dial up user login passwords. The TACACS protocol was formally specified, but the spec is not generally available.

594: According to the principle of accountability, what action should be traceable to a specific user? A. Material B. Intangible C. Tangible D. Significant

D Explanation: The principle of accountability has been described in many reference; it is a principle by which specific action can be traced back to an individual. As mentioned by Idrach, any significant action should be traceable to a specific user. The definition of "Significant" is entirely dependant on your business circumstances and risk management model. It was also mentioned by Rino that tracing the actions of a specific user is fine but we must also be able to ascertain that this specific user was responsible for the uninitiated action.

946: Which one of the following is the reason for why hyperlink spoofing attacks are usually successful? A. Most users requesting DNS name service do not follow hyperlinks. B. The attack performs user authentication with audit logs. C. The attack relies on modifications to server software. D. Most users do not make a request to connect to a DNS names, they follow hyperlinks.

D Explanation: The problem is that most users do not request to connect to DNS names or even URLs, they follow hyperlinks... But, whereas DNS names are subject to "DNS spoofing" (whereby a DNS server lies about the internet address of a server) so too are URLs subject to what I call "hyperlink spoofing" or "Trojan HTML", whereby a page lies about an URLs DNS name. Both forms of spoofing have the same effect of steering you to the wrong internet site, however hyperlink spoofing is technically much easier than DNS spoofing. http://www.brd.ie/papers/sslpaper/sslpaper.html

967: Man-in-the-middle attacks are a real threat to what type of communication? CISSP Actualtests.com - The Power of Knowing A. Communication based on random challenge. B. Communication based on face to face contact. C. Communication based on token. D. Communication based on asymmetric encryption.

D Explanation: The weakest point in the communication based on asymmetric encryption is the knowledge about the real owners of keys. Somebody evil could generate a key pair, give the public key away and tell everybody, that it belongs to somebody else. Now, everyone believing it will use this key for encryption, resulting in the evil man being able to read the messages. If he encrypts the messages again with the public key of the real recipient, he will not be easily recognized. This sort of attack is called ``man-in-the-middle'' attack and can only be prevented by making sure, public keys really belong to the one being designated as owner.

293: The word "smart card" has meanings of: A. Personal identity token containing IC-s. B. Processor IC card. C. IC card with ISO 7816 interface. D. All of the choices.

D Explanation: The word "smart card" has four different meanings (in order of usage frequency): CISSP Actualtests.com - The Power of Knowing IC card with ISO 7816 interface Processor IC card Personal identity token containing IC-s Integrated Circuit(s) Card is ad ID-1 type (specified in ISO 7810) card, into which has been inserted one or more integrated circuits. [ISO 7816]

251: Which of the following methods is more microscopic and will analyze the direction of the ridges of the fingerprints for matching? A. None of the choices. B. Flow direct C. Ridge matching CISSP Actualtests.com - The Power of Knowing D. Minutia matching

D Explanation: There are two approaches for capturing the fingerprint image for matching: minutia matching and global pattern matching. Minutia matching is a more microscopic approach that analyzes the features of the fingerprint, such as the location and direction of the ridges, for matching. The only problem with this approach is that it is difficult to extract the minutiae points accurately if the fingerprint is in some way distorted. The more macroscopic approach is global pattern matching where the flow of the ridges is compared at all locations between a pair of fingerprint images; however, this can be affected by the direction that the image is rotated.

204: Which of the following is best known for capturing security requirements of commercial applications? A. Lattice B. Biba C. Bell LaPadula D. Clark and Wilson

D Explanation: This model attempts to capture security requirements of commercial applications. 'Military' and 'Commercial' are shorthand for different ways of using computers. This model has emphasis on integrity: Internal consistency: properties of the internal state of a system External consistency: relation of the internal state of a system to the outside world

598: What types of computer attacks are most commonly reported by IDSs? A. System penetration B. Denial of service C. System scanning D. All of the choices

D Explanation: Three types of computer attacks are most commonly reported by IDSs: system scanning, denial of service (DOS), and system penetration. These attacks can be launched locally, on the attacked machine, or remotely, using a network to access the target. An IDS operator must understand the differences between these types of attacks, as each requires a different set of responses.

174: The Lattice Based Access Control model was developed MAINLY to deal with: A. Affinity B. None of the choices. C. Confidentiality D. Integrity

D Explanation: We think this is D: "Identity-Based Access Control" "...grant or deny access based on the identity of the subject. ...user identity or group membership." Harris, 3rd Ed, p 163. Group membership would be part of a user profile. Rule based based can be ID or "a set of complex rules that must be met. ... Rule-based access control is not necessarily identity based." Harris, 3rd Ed, p 167. So item "C" is out. "A" and "B" are not access control methods. I would note that in Harris, there is no reference to "ID based access control". "Role-based access control would be the VERY best answer to the question - role information would be included as part of the users profile.

1273: Phreakers are hackers who specialize in telephone fraud. What type of telephone fraud manipulates the line voltage to receive a tool-free call? A. Red Boxes B. Blue Boxes C. White Boxes CISSP Actualtests.com - The Power of Knowing D. Black Boxes

D Explanation: A Black Box is a device that is hooked up to your phone that fixes your phone so that when you get a call, the caller doesn't get charged for the call. This is good for calls up to 1/2 hour, after 1/2 hour the Phone Co. gets suspicious, and then you can guess what happens. The Red box basically simulates the sounds of coins being dropped into the coin slot of a payphone. The traditional Red Box consisting of a pair of Wien-bridge oscillators with the timing controlled by 555 timer chips. The Blue Box, The mother of all boxes, The first box in history, which started the whole phreaking scene. Invented by John Draper (aka "Captain Crunch") in the early 60s, who discovered that by sending a tone of 2600Hz over the telephone lines of AT&T, it was possible to make free calls. The White Box turns a normal touch tone keypad into a portable unit. This kind of box can be commonly found in a phone shop.

1333: Examples of types of physical access controls include all except which of the following? A. badges B. locks C. guards D. passwords

D Explanation: A password is not a physical thing, it's a logical one. You can control physical access with armed guards, by locking doors and using badges to open doors, but you can't relate password to a physical environment. Just to remember, Passwords are used to verify that the user of an ID is the owner of the ID. The ID-password combination is unique to each user and therefore provides a means of holding users accountable for their activity on the system. They are related to software, not to hardware.

1203: Application Level Firewalls are commonly a host computer running proxy server software, which makes a? A. Proxy Client B. Proxy Session C. Proxy System D. Proxy Server

D Explanation: A proxy server is a server that sits between a client and server application, such as a Web browser and a source web server. It intercepts all requests to the real server to see if it can fulfill the requests itself. If not, it forwards the request to the original source web server. Firewalls usually provides this kind of services to have more control over user request and allow / deny the traffic of those through the gateway. At this time the most common Proxy server is for HTTP protocol, we can also have proxies for SMTP and FTP.

1350: Your co-worker is studying for the CISSP exam and has come to you with a question. What is ARP poisoning? A. Flooding of a switched network B. A denial of service that uses the DNS death ping C. Turning of IP to MAC resolution D. Inserting a bogus IP and MAC address in the ARP table CISSP Actualtests.com - The Power of Knowing E. Modifying a DNS record

D Explanation: ARP poisoning is a masquerading attack where the attacker inserts a bogus IP and MAC address in a victims ARP table or into the table of a switch. This has the effect of redirecting traffic to the attacker and not to the intended computer.

1290: CISSP Actualtests.com - The Power of Knowing In the following choices there is one that is a typical biometric characteristics that is not used to uniquely authenticate an individual's identity? A. Retina scans B. Iris scans C. Palm scans D. Skin scans

D Explanation: Answer A, B and C can be used to uniquely identify a person, but in the case of the Skin, there are no unique characteristics that can differentiate two distinct individuals in an acceptable accurate way. In the case of the IRIS and the Retina, there are not two of them equal. In the case of the palm, every person has different marks on it. The skin is common to all and does not have specific textures or marks to make it unique in comparison to another individual.

1268: Which question is NOT true concerning Application Control? A. It limits end users of applications in such a way that only particular screens are visible. B. Only specific records can be requested choice. C. Particular uses of the application can be recorded for audit purposes. D. Is non-transparent to the endpoint applications so changes are needed to the applications involved.

D Explanation: Application control provides a transparent feeling to endpoint applications when changes are needed, this is one of the features of it. With application control you can audit certain use of the applications involved and only specify record of your choice. There is also the possibility to limit the end users applications to provide access to only certain screens. Check your CISSP documentation about Application Control. CISSP Actualtests.com - The Power of Knowing

1264: When should a post-mortem review meeting be held after an intrusion has been properly taken care of? A. Within the first three months after the investigation of the intrusion is completed. B. Within the first week after prosecution of intruders have taken place, whether successful or not. C. Within the first month after the investigation of the intrusion is completed. D. Within the first week of completing the investigation of the intrusion. CISSP Actualtests.com - The Power of Knowing

D Explanation: As stated in CISSP documentation, you should make post mortem review meetings after taking care of the intrusion, and no more than one week after the facts. Its not a good practice to wait more than this time, it's a matter of common sense too, three months, one month, 2 weeks, its too much time.

1162: In a discretionary mode, which of the following entities is authorized to grant information access to other people? A. Manager B. Group leader C. Security manager D. User

D Explanation: Discretionary control is the most common type of access control mechanism implemented in computer systems today. The basis of this kind of security is that an individual user, or program operating on the user's behalf, is allowed to specify explicitly the types of access other users (or programs executing on their behalf) may have to information under the user's control. Discretionary security differs from mandatory security in that it implements the access control decisions of the user. Mandatory controls are driven by the results of a comparison between the user's trust level or clearance and the sensitivity designation of the information. CISSP Actualtests.com - The Power of Knowing

1327: Which of the following are functions that are compatible in a properly segregated environment? A. Application programming and computer operation. B. System programming and job control analysis. C. Access authorization and database administration. D. System development and systems maintenance.

D Explanation: If you think about it, System development and system maintenance are perfectly compatible, you can develop in the systems for certain time, and when it time for a maintenance, you stop the development process an make the maintenance. It's a pretty straight forward process. The other answer do not provide the simplicity and freedom of this option.

1239: Why is public key cryptography recommended for use in the process of securing facsimiles during transmission? A. Keys are never transmitted over the network. B. Data compression decreases key change frequency. C. Key data is not recognizable from facsimile data. D. The key is securely passed to the receiving machine.

D Explanation: In this method of cryptography we use 2 keys, one to encrypt the data, and another to decrypt it. In Public Key Cryptography, the users have a public and a private key, the public key is of free distribution and is usually published in a directory, while the private keys must be keep secure. This allows the keys to pass in a secure fashion to the receiving machine, its because the public key is not confidential and can be send through a CISSP Actualtests.com - The Power of Knowing secure channel. You need to use a certification authority to make this kind of cryptography work.

1322: Which of the following protocols does not operate at the data link layer (layer 2)? A. PPP B. RARP C. L2F D. ICMP

D Explanation: Internet Control Message Protocol. ICMP is used for diagnostics in the network. The Unix program, ping, uses ICMP messages to detect the status of other hosts in the net. ICMP messages can either be queries (in the case of ping) or error reports, such as when a network is unreachable. This protocol resides in layer 3 of the OSI model (Network layer). CISSP Actualtests.com - The Power of Knowing

1175: Which of the following is not an Orange Book-defined life cycle assurance requirement? A. Security testing B. Design specification and testing C. Trusted distribution D. System integrity

D Explanation: Life cycle assurance is more than configuration management. Reference: "Operational assurance focuses on the basic features and architecture of a system that lend themselves to supporting security. There are five requirements or elements of operation assurance: * System architecture * System integrity * Covert channel analysis * Trusted facility management * Trusted Recovery Life cycle assurance focuses on the controls and standards that are necessary for designing, building, and maintaining a system. The following are the four requirements or elements of life CISSP Actualtests.com - The Power of Knowing cycle assurance: * Security testing * Design specification and testing * Configuration Management * Trusted distribution" Pg 398 Tittel

1199: Why would anomaly detection IDSs often generate a large number of false positives? A. Because they can only identify correctly attacks they already know about. B. Because they are application-based are more subject to attacks. C. Because they cant identify abnormal behavior. D. Because normal patterns of user and system behavior can vary wildly.

D Explanation: One of the most obvious reasons why false alarms occur is because tools are stateless. To detect an intrusion, simple pattern matching of signatures is often insufficient. However, that's what most tools do. Then, if the signature is not carefully designed, there will be lots of matches. For example, tools detect attacks in sendmail by looking for the words "DEBUG" or "WIZARD" as the first word of a line. If this is in the body of the message, it's in fact innocuous, but if the tool doesn't differentiate between the header and the body of the mail, then a false alarm is generated. Finally, there are many events happening in the course of the normal life of any system or network that can be mistaken for attacks. A lot of sysadmin activity can be catalogued as CISSP Actualtests.com - The Power of Knowing anomalous. Therefore, a clear correlation between attack data and administrative data should be established to cross-check that everything happening on a system is actually desired. Normal patterns and user activities are usually confused with attacks by IDS devices, its expected that the 2nd generations IDS systems will decrease the percent of false positives.

1254: Which of the following elements is not included in a Public Key Infrastructure (PKI)? A. Timestamping B. Lightweight Directory Access Protocol (LDAP) C. Certificate revocation D. Internet Key Exchange (IKE)

D Explanation: Public key cryptography is one mechanism that is often used to fulfill the security requirements necessary to conduct electronic transactions over public networks. PKI (public key infrastructure) and cryptography based solutions are taking the lead in secure e-commerce. PKI addresses nonrepudiation of identity using a dual-key encryption system that allows users to uniquely sign documents with a digital signature. Public key cryptography uses pairs of keys, each pair consisting of one public key and one private key. Information encrypted with one key in the pair can only be decrypted with the other key. LDAP is issued to bring user information and Timestamping to track changes over time. PKI also relies on certificated and CRL (Certificate Revocation list) to discard compromised, expired digital certificates. CISSP Actualtests.com - The Power of Knowing

1172: At which of the following phases of a software development life cycle are security and access controls normally designed? A. Coding B. Product design C. Software plans and requirements D. Detailed design

D Explanation: Security controls and access controls are normally designed in the "Detailed" phase of design. In this phase you have the design of many of the security features of your development like authentication, confidentiality functionality, non repudiation capabilities. In this phase you can also define what is going to be the access control method for the software, we can make it discretionary (less restrictive), mandatory (more restrictive), role based and others.

1277: Immune to the effects of electromagnetic interference (EMI) and therefore has a much longer effective usable length (up to two kilometers in some cases) is? A. Coaxial cable B. Twisted Pair cable C. Axial cable D. Fiber Optic cable

D Explanation: Since fiber optics does not use electrical signals to transmit the information (it uses lights that goes through the mirrored silvered cable from source to end), its not affected by EMI (Electro Magnetic Interference) like other copper transmission methods like 10base5 and 10base2, therefore EMI does not affect the possible transmission distance. Fiber optics can have a great distance between end points, much greater than the copper transmission methods. Examples of Fiber optics standards are: 100BaseFX and 1000BaseFX. CISSP Actualtests.com - The Power of Knowing

1189: Which of the following is the BEST way to prevent software license violations? A. Implementing a corporate policy on copyright infringements and software use. B. Requiring that all PCs be diskless workstations. C. Installing metering software on the LAN so applications can be accessed through the metered software. D. Regularly scanning used PCs to ensure that unauthorized copies of software have not been loaded on the PC.

D Explanation: Since its impossible to control all the efforts of the users to install software without the proper licenses in their PC´s (Specially downloaded from the Internet), the best way to prevent licenses violations is through regular audit to every single user PC to see what's the installed programs are and what's the nature of them (Shareware, freeware, licensed). We cant use LAN monitoring software because not all the applications are network enabled, also, there is usually a policy about software installation, but the users do not rely on them many times. It also a very nice practice to punish the users making software license violations.

1246: Which of the following is an ip address that is private? (i.e. reserved for internal networks, and not a valid address to use on the Internet)? A. 172.5.42.5 B. 172.76.42.5 C. 172.90.42.5 D. 172.16.42.5

D Explanation: The IP address 172.16.42.5 is contained in a class B reserved network, IANA reserved the 172.16.0.0 through 172.31.255.255 networks for internal use, this network its CISSP Actualtests.com - The Power of Knowing not routable in Internet and its commonly used in intranets. Class B networks are used in medium-sized networks. In class B networks, the two high order bits are always 10, and then remaining bits are used to define 16.384 networks, each with as many as 65.534 hosts attached. Examples of valid Class B networks include Microsoft and Exxon.

1215: Which layer defines the X.25, V.35, X,21 and HSSI standard interfaces? A. Transport layer B. Network layer C. Data link layer D. Physical layer

D Explanation: The Physical Layer is the layer that is concerned with the signaling of the message and the interface between the sender or receiver and the medium. The physical CISSP Actualtests.com - The Power of Knowing layer is generally defined by one of the standards bodies and carries a designation that indicates the characteristics of the connection. Among frequently used physical layers standards are EIA-232-D, ITU V.35, and some of the X series (X.21/X.21bis, for example).

1228: How do the Information Labels of Compartmented Mode Workstation differ from the Sensitivity Levels of B3 evaluated systems? A. Information Labels in CMW are homologous to Sensitivity Labels, but a different term was chosen to emphasize that CMW's are not described in the Orange Book. B. Information Labels contain more information than Sensitivity Labels, thus allowing more granular access decisions to be made. C. Sensitivity Labels contain more information than Information Labels because B3+ systems should store more sensitive data than workstations. D. Information Labels contain more information than Sensitivity Labels, but are not used by the Reference Monitor to determine access permissions.

D Explanation: The primary goal of the compartmented mode workstation (CMW) project was to articulate the security requirements that workstations must meet to process highly classified intelligence data. As a basis for the validity of the requirements developed, a prototype was implemented which demonstrated that workstations could meet the requirements in an operationally useful manner while still remaining binary compatible with off-the-shelf software. The security requirements not only addressed traditional CISSP Actualtests.com - The Power of Knowing security concerns but also introduced concepts in areas such as labeling and the use of a trusted window management system. The CMW labeling paradigm is based on associating two types of security labels with objects: sensitivity levels and information labels. Sensitivity levels describe the levels at which objects must be protected. Information labels are used to prevent data over classification and also provide a mechanism for associating with data those markings that are required for accurate data labeling, but which play no role in access control decisions. The use of a trusted window manager allows users to easily operate at multiple sensitivity levels and provides a convenient mechanism for communicating security information to users in a relatively unobtrusive manner. Information labels are not used by reference monitor, permissions are referenced in Sensibility labels.

1274: Which of the following groups represents the leading source of computer crime losses? A. Hackers B. Industrial saboteurs C. Foreign intelligence officers D. Employees

D Explanation: This can be checked at the computer crime static's on the web. Most of the attacks, actually 70% of them, come from inside the company, and 80% of them from employees of it. This is a reality, when we protect our infrastructure be sure to give great importance to internal security, we don't when is one of the company employees going to make a strike. Hackers are also important, but less than our own employees.

1185: Intrusion detection has which of the following sets of characteristics. A. It is adaptive rather than preventive. B. It is administrative rather than preventive. C. It is disruptive rather than preventative. D. It is detective rather than preventative.

D Explanation: This is one of the features of intrusion detections, instead of being pro-active, it has a reactive behavior. When we set an IDS system inside of our network or hosts, the IDS agent is constantly monitoring in real time what activities are being performed in the infrastructure. If the IDS founds a malicious activity taking place it can take actions against it like disabling interfaces, alerting the administrators or sending network attacks to the source to put it out of service. CISSP Actualtests.com - The Power of Knowing As a difference to the detective behavior of IDS, we can also increase the security with practices like hardening our systems ,this is considered a preventive practice.

1213: Making sure that the data is accessible when and where it is needed is which of the following? A. Confidentiality B. Integrity C. Acceptability CISSP Actualtests.com - The Power of Knowing D. Availability

D Explanation: This is one of the pillars of network security. We can say that the data is available if we can access to it when we need it. This what is referred in the question, Availability refers to get access to data when and where you need it. Confidentiality deals with encryption and data protection against third party interception. Integrity deals with digital signatures and assures that the data has not changed. Acceptability is not a related term.

1216: Related to information security, availability is the opposite of which of the following? A. Delegation B. Distribution C. Documentation D. Destruction

D Explanation: This is the correct term, remember that Availability refers to get access to data when and where you need it. When we talk about destruction, we are saying the opposite, if your information is destroyed, you cant access to it neither when or where you want it. Delegation deals with permissions, distribution deals with deployment and documentation deals with information and how to´s. The term we are looking here is definitively "destruction".

1289: The security of a computer application is most effective and economical in which of the following cases? A. The system is optimized prior to the addition of security. B. The system is procured off-the-shelf. C. The system is customized to meet the specific security threat. D. The system is designed originally to provide the necessary security.

D Explanation: This is very obvious, if your system is designed from the ground up to provide security, its going to be cheaper and more effective at the end, because you don't need re-analysis, re-coding, and re-structure of the internal code of the computer application. If you don't address security at the beginning you will also need to spend time and money reviewing the code to try to put the security infrastructure in some place of it.

1152: Which one is an example of a man-in-the-middle attack? A. Buffer overflow B. DoS attack C. All of the above D. None of the above

D Explanation: Wrong: Both A and B could be the result of a man-in-the-middle attack, but neither are man-in-the-middle attacks. For example someone who uses a packet capturing device, such as a "sniffer" to obtain an unencrypted user ID and password to one or more PCs or servers and then the platforms to launch a DOS attach or create a Buffer Overflow by exploiting an application flaw or OS Vulnerability.

1038: Which of the following is less likely to accompany a contingency plan, either within the plan itself or in the form of an appendix? A.) Contact information for all personnel B.) Vendor contract information, including offsite storage and alternate site C.) Equipment ad system requirements lists of hardware, software, firmware, and other resources required to support system operations D.) The Business Impact Analysis

D Explanation: You use the BIA as a guideline to create the contingency plan.

162: What does * (star) integrity axiom mean in the Biba model? A.) No read up B.) No write down C.) No read down D.) No write up

D "Biba has two integrity axioms: 1. Simple Integrity Axiom The Simple Integrity Axiom (SI Axiom) state that a subject at a specific classification level cannot read data with a lower classification level. This is often shortened to "no read down." 1. Integrity Axiom The * (star) Integrity Axiom (* Axiom) states that a subject at a specific classification level cannot write data to a higher classification level. This is often shortened to "no write up."" Pg 347 Tittel: CISSP Study Guide

746: Which of the following statements is true about data encryption as a method of protecting data? A.) It should sometimes be used for password files B.) It is usually easily administered C.) It makes few demands on system resources D.) It requires careful key Management

D "Cryptography can be used as a security mechanism to provide confidentiality, integrity, and authentication, but not if the keys are compromised in any way. The keys can be captured, modified, corrupted, or disclosed to unauthorized individuals. Cryptography is based on a trust mode. Individuals trust each other to protect their own keys, they trust the administrator who is maintaining the keys, and they trust a server that holds, maintains and distributes the keys. Many administrators know that key management causes one of the biggest headaches in cryptographic implementation. There is more to key maintenance than using them to encrypt messages. The keys have to be distributed securely to the right entities and updated continuously. The keys need to be protected as they are being transmitted and while they are being stored on each workstation and server. The keys need to be generated, destroyed, and recovered properly, Key management can be handled through manual or automatic processes. Unfortunately, many companies use cryptographic keys, but rarely if ever change them. This is because of the hassle of key management and because the network administrator is already CISSP Actualtests.com - The Power of Knowing overtaxed with other tasks or does not realize the task actually needs to take place. The frequency of use of a cryptographic key can have a direct correlation to often the key should be changed. The more a key is used, the more likely it is to be captured and compromised. If a key is used infrequently, then this risk drops dramatically. The necessary level of security and the frequency of use can dictate the frequency of the key updates. Key management is the most challenging part of cryptography and also the most crucial. It is one thing to develop a very complicated and complex algorithm and key method, but if the keys are not securely stored and transmitted, it does not really matter how strong the algorithm is. Keeping keys secret is a challenging task." Pg 512-513 Shon Harris CISSP Certification All-In-One Exam Guide

Eliminating attributes in a table that are not dependent on the primary key of that table D.) Eliminating duplicate key fields by putting them into separate tables

D "Data Normalization Normalization is an important part of database design that ensures that attributes in a table depend only on the primary key. This process makes it easier to maintain data and have consistent reports. Normalizing data in the database consists of three steps: 1.) Eliminating any repeating groups by putting them into separate tables 2.) Eliminating redundant data (occurring in more than one table) 3.) Eliminating attributes in a table that are not dependent on the primary key of that table" Pg. 62 Krutz: The CISSP Prep Guide: Gold Edition

1042: What is the minimum and customary practice of responsible protection of assets that affects a community or societal norm? A. Due diligence B. Risk mitigation C. Asset protection D. Due care

D "Due care and due diligence are terms that are used throughout this book. Due diligence is the act of investigating and understanding the risks the company faces. A company practices due care by developing security policies, procedures, and standards. Due care shows that a company has taken responsibility for the activities that take place within the corporation and has taken the necessary steps to help protect the company, its resources, and employees from possible risks. So due diligence is understanding the current threats and risks and due care is implementing countermeasures to provide protection from those threats. If a company does not practice due care and due diligence pertaining to the security of its assets, it can be legally charged with negligence and held accountable for any ramifications of that negligence." Pg. 85 Shon Harris: All-in-One CISSP Certification "The following list describes some of the actions required to show that due care is being properly practiced in a corporation: 1. Adequate physical and logical access controls 2. Adequate telecommunication security, which could require encryption 3. Proper information, application, and hardware backups 4. Disaster recovery and business continuity plans 5. Periodic review, drills, tests, and improvement in disaster recovery and business continuity plans 6.

Removing the hard drive to view the output of the forensic imaging software. D. Directing the output of the forensic imaging software to the small computer system interface (SCSI).

D "It is very important that the person, or people, conducting the forensics investigation is skilled in this trade and knows what to look out for. If a person reboots the attacked system or goes around looking at different files, it could corrupt viable evidence, change timestamps on key files, and erase footprints the criminal may have left. One very good first step is to make a sound image of the attacked system and perform forensic analysis on this copy. This will ensure that the evidence stays unharmed on the original system in case some steps in the investigation actually corrupt or destroy data. Also the memory of the system should be dumped to a file before doing any work on the system or powering it down." - Shon Harris All-in-one CISSP Certification Guide pg 672-673 PCMCIA to SCSI and parallel to SCSI forensic products can be found at the following vendor. http://www.icsforensic.com/products_cat_fr.cfm

D "SQL commands include Select, Update, Delete, Grant, and Revoke." Pg. 62 Krutz: The CISSP Prep Guide: Gold Edition "Developed by IBM, SQL is a standard data manipulation and relational database definition language. The SQL Data Definition Language creates and deletes views and relations (tables). SQL commands include Select, Update, Delete, Insert, Grant, and Revoke. The latter two commands are used in access control to grant and revoke privileges to resources. Usually, the owner of an object can withhold or transfer GRANT privileges to an object to another subject. If the owner intentionally does not transfer the GRANT privileges, however, which are relative to an object to the individual A, A cannot pass on the GRANT privileges to another subject. In some instances, however, this security control can be circumvented. For example, if A copies the object, A essentially becomes the owner of that object and thus can transfer the GRANT privileges to another user, such as user B. SQL security issues include the granularity of authorization and the number of different ways you can execute the same query. Pg. 63 Krutz: The CISSP Prep Guide: Gold Edition.

D "The following are the three most common VPN communications protocol standards: Point-to-Point Tunneling Protocol(PPTP). PPTP works at the Data Link Layer of the OSI model. Designed for individual client to server connections, it enables only a single point-to-point connection per session. This standard is very common with asynchronous connections that use Win9x or NT clients. PPTP uses native Point-to-Point Protocol (PPP) authentication and encryption services. Layer 2 Tunneling Protocol (L2TP). L2TP is a combination of PPTP and the earlier Layer 2 Forwarding (L2F) Protocol that works at the Data Link Layer like PPTP. It has become an accepted tunneling standard for VPN's. In fact, dial-up VPNs use this standard quite frequently. Like PPTP, this standard was designed for single point-to-point client to server connections. Not that multiple protocols can be encapsulated within the L2TP tunnel, but do not use encryption like PPTP. Also, L2TP supports TACACS+ and RADIUS, but PPTP does not. IPSEC. IPSec operates at the Network Layer and it enables multiple and simultaneous tunnels, unlike the single connection of the previous standards. IPSec has the functionality to encrypt and authenticate IP data. It is built into the new Ipv6 standard, and is used as an add-on to the current CISSP Actualtests.com - The Power of Knowing Ipv4. While PPTP and L2TP are aimed more at dial-up VPNs, IPSec focuses more on network-to-network connectivity." Pg. 123-125 Krutz: The CISSP Prep Guide: Gold Edition.

117: What is the PRIMARY component of a Trusted Computer Base? CISSP Actualtests.com - The Power of Knowing A. The computer hardware B. The security subsystem C. The operating system software D. The reference monitor

D "The security kernel is made up of hardware, software, and firmware components that fall within the TCB and implements and enforces the reference monitor concept. The security kernel mediates all access and functions between subjects and objects. The security kernel is the core of the TCB and is the most commonly used approach to building trusted computing systems. There are three main requirements of the security kernel: It must provide isolation for the processes carrying out the reference monitor concept, and the processes must be tamperproof. It must be invoked for every access attempt and must be impossible to circumvent. Thus, the security kernel must be implemented in a complete and foolproof way. It must be samall enough to be able to be tested and verified in a complete and comprehensive manner. These are the requirements of the reference monitor; therefor,they are the requirements of the components that provide and enforce the reference monitor concept-the security kernel." - Shon Harris, "CISSP All-in-One Exam Guide", 3rd Ed, p

For example, an elliptic curve key of 160 bits is equivalent to 1024-bit RSA key."

96: An example of an individual point of verification in a computerized application is A. An inference check. B. A boundary protection. C. A sensitive transaction. CISSP Actualtests.com - The Power of Knowing D. A check digit.

D Checkdigit: A one-digit checksum. Checksum: A computed value which depends on the contents of a block of data and which is transmitted or stored along with the data in order to detect corruption of the data. The receiving system recomputes the checksum based upon the received data and compares this value with the one sent with the data. If the two values are the same, the receiver has some confidence that the data was received correctly. The checksum may be 8 bits (modulo 256 sum), 16, 32, or some other size. It is computed by summing the bytes or words of the data block ignoring overflow. The checksum may be negated so that the total of the data words plus the checksum is zero.

350: What type of wiretapping involves injecting something into the communications? A. Aggressive B. Captive C. Passive D. Active

D Most communications are vulnerable to some type of wiretapping or eavesdropping. It can usually be done undetected and is referred to as a passive attack versus an active attack. - Shon Harris All-in-one CISSP Certification Guide pg 649 "(I) An attack that intercepts and accesses data and other information contained in a flow in a communication system. (C) Although the term originally referred to making a mechanical connection to an electrical conductor that links two nodes, it is now used to refer to reading information from any sort of medium used for a link or even directly from a node, such as gateway or subnetwork switch. (C) "Active wiretapping" attempts to alter the data or otherwise affect the flow; "passive wiretapping" only attempts to observe the flow and gain knowledge of information it contains. (See: active attack, end-to-end encryption, passive attack.)" http://www.linuxsecurity.com/dictionary/dict-455.html

1028: Which of the following business continuity stages ensures the continuity strategy remains visible? A. Backup, Recover and Restoration B. Testing Strategy Development C. Post Recovery Transition Data Development D. Implementation, Testing and Maintenance

D Once the strategies have been decided upon, they need to be documented and put into place. This moves the efforts from a purely planning stage to an actual implementation and action phase...The disaster recovery and continuity plan should be tested periodically because an environment continually changes and each time it is tested, more improvements may be uncovered...The plan's maintenance can be incorporated into change management procedures so that any changes in the environment will be sure to be reflected in the plan itself. - Shon Harris All-in-one CISSP Certification Guide pg 611

D SPAM - The term describing unwanted email, newsgroup, or discussion forum messages. Spam can be innocuous as an advertisement from a well-meaning vendor or as malignant as floods or unrequested messages with viruses or Trojan horses attached SYN Flood Attack - A type of DoS. A Syn flood attack is waged by not sending the final ACK packet, which breaks the standard three-way handshake used by TCP/IP to initiate communication sessions. Ping of death attack - A type of DoS. A ping of death attack employs an oversized ping packet. Using special tools, an attacker can send numerous oversized ping packets to a victim. In many cases, when the victimized system attempts to process the packets, an error occurs causing the CISSP Actualtests.com - The Power of Knowing system to freeze, crash, or reboot.

957: How does a teardrop attack work? CISSP Actualtests.com - The Power of Knowing

Reference: Another attack that relies on poor TCP/IP implementation is Teardrop < http://www.rage.mircx.com/knowledge/tcpip-teardrop.htm> , which exploits defects in the way systems reassemble IP packet fragments. On their way from hither to you on the Internet, an IP packet may be broken up into smaller pieces. Each of these still has the original IP packet's header, as well as an offset field that identifies which bytes of the original packet it contains. With this information, an ordinary broken packet is reassembled at its destination and network continues uninterrupted. When a Teardrop attack hits, your server is bombarded with IP fragments that have overlapping offset fields. If your server or router can't disregard these fragments and attempts to reassemble them, your box will go castors up quickly. If your systems are up-to-date, or if you have a firewall that blocks Teardrop packets, you shouldn't have any trouble.
