A NIDS has sensors that monitor the traffic entering and leaving a firewall, and reports back to the central device for analysis.

d. *A NIDS has sensors that monitor the traffic entering and leaving a firewall, and reports back to the central device for analysis.* A network intrusion prevention system (NIPS) is similar to a NIDS in that it monitors network traffic to immediately react to block a malicious attack. One of the major differences between a NIDS and a NIPS is its location. A NIDS has sensors that monitor the traffic entering and leaving a firewall, and reports back to the central device for analysis. A NIPS, on the other hand, would be located "in line" on the firewall itself. This can allow the NIPS to more quickly take action to block an attack.

*If an asset is valued at 100,000, the threat exposure factor of a risk affecting that asset is 25%, and the annualized rate of occurrence is 20%, what is the ALE?* a. $5,000 b. $20,000 c. $25,000 d. $45,000

a. *$5,000* The annualized loss expectancy (ALE) is the product of the SLE (value times exposure factor) and the ARO or $20% of 100,000 × 25% = $5,000. Answer B is incorrect because $20,000 represents the asset value times ARO. Answer C is incorrect because the value times the exposure factor represents the single loss expectancy (SLE) rather than the annual loss expectancy (ALE). Answer D is simply an incorrectly calculated value.

Security-Related Policies and Procedures *Which rule of evidence within the United States involves Fourth Amendment protections?* a. Admissible b. Complete c. Reliable d. Believable

a. *Admissible* Admissibility involves collecting data in a manner that ensures its viability in court, including legal requirements such as the Fourth Amendment protections against unlawful search and seizure. Answers B and C are incorrect because data must be collected completely and protected against modification to ensure reliability, but these are not concerns of the Fourth Amendment. Answer D is incorrect because believability focuses on evidence being understandable, documented, and not subject to modification during transition.

*Which of the following are steps that can be taken to harden FTP services?* a. Anonymous access to shared files of questionable or undesirable content should be limited. b. Regular review of networks for unauthorized or rogue servers. c. Technologies that allow dynamic updates must also include access control and authentication. d. Unauthorized zone transfers should also be restricted.

a. *Anonymous access to shared files of questionable or undesirable content should be limited.* Anonymous access to shared files of questionable or undesirable content should be limited for proper FTP server security. Answer B is incorrect because it is a hardening practice for DHCP services. Answers C and D are incorrect because they are associated with hardening DNS service.

Access Control and Identity Management *Which type of authorization provides no mechanism for unique logon identification?* a. Anonymous b. Kerberos c. TACACS d. TACACS+

a. *Anonymous* During anonymous access, such as requests to a public FTP server, unique identify of the requester is not determined and so cannot be used for personalized logon identification. Answers B, C, and D are incorrect because authorization services such as Kerberos, TACACS, and its replacement TACACS+ all verify access requests against a list of authorized credentials and so can log individual visits and identify access request logons.

Antivirus software is used to scan for malicious code in email and downloaded files. Antispam, antispyware software can add another layer of defense to the infrastructure. Answer C is incorrect because content filtering is done at the server level to keep host machines from accessing certain content. Answer D is incorrect because web tracking software merely tracks the sites a person visited.

*Which of the following is the preferred type of encryption used in SaaS platforms?* a. Application level b. Database level c. Media level d. HSM level

a. *Application level* In a software-as-a-service (SaaS) environment, application-level encryption is preferred because the data is encrypted by the application before being stored in the database or file system. The advantage is that it protects the data from the user all the way to storage. Answer B is incorrect because in cloud implementations data should be encrypted at the application layer rather than within a database due to the complexity involved, and media encryption is managed at the storage layer. Answer C is incorrect because encryption of a complete virtual machine on infrastructure-as-a-service (IaaS) could be considered media encryption. Answer D is incorrect because a hardware security module (HSM) solution is mainly found in private datacenters that manage and offload cryptography with dedicated hardware appliances.

a. *Buffer overflow* A buffer overflow occurs when a program or process attempts to store more data in a buffer than the buffer was intended to hold. The overflow of data can flow over into other buffers, overwriting or deleting data. A denial of service is a type of attack in which too much traffic is sent to a host, preventing it from responding to legitimate traffic. A distributed denial of service is similar, but it is initiated through multiple hosts; therefore, answers B and C are incorrect. Although answer D sounds correct, it is not.

*Never inserting untrusted data except in allowed locations can be used to mitigate which of the following attacks? (Select two answers.)* a. Buffer overflow b. Cross-site request forgery (XSRF) c. Cross-Site Scripting (XSS) d. Input validation error

a. *Buffer overflow* d. *Input validation error* A buffer overflow is a direct result of poor or incorrect input validation or mishandled exceptions, and input validation errors are a result of improper field checking in the code. Answer B is incorrect because Cross-site request forgery (XSRF) is an attack in which the end user executes unwanted actions on a web application while they are currently authenticated. Answer C is incorrect because Cross-Site Scripting (XSS) vulnerabilities can be used to hijack the user's session or to cause the user accessing malware-tainted Site A to unknowingly attack Site B on behalf of the attacker who planted code on Site A.

*When a certificate authority revokes a certificate, notice of the revocation is distributed via what?* a. Certificate revocation list b. Certificate policy c. Digital signature d. Certificate practice statement

a. *Certificate revocation list* Certificate revocation lists are used to identify revoked certificates; however, the Online Certificate Status Protocol (OCSP), which provides certificate status in real time, has been created as an alternative to CRLs. Answers B and D are both incorrect because these terms relate to the policies and practices of certificates and the issuing authorities. Answer C is incorrect because a digital signature is an electronic signature used for identity authentication.

Physical and Hardware-Based Security *Which of the following is an example of perimeter security?* a. Chain link fence b. Video camera c. Elevator d. Locked computer room

a. *Chain link fence* Perimeter security involves creating a perimeter or outer boundary for a physical space. Video surveillance systems wouldn't be considered a part of perimeter security, but they can be used to enhance physical security monitoring.

*Evidence is inadmissible in court if which of the following is violated or mismanaged?* a. Chain of custody b. Service-level agreement c. Privacy policy d. Change management

a. *Chain of custody* If the chain of custody is violated or mismanaged, evidence is inadmissible in court. Service-level agreements (SLAs), privacy policies, and change management aren't associated with evidence gathering or forensics.

Disaster Recovery and Incident Response *Your company is about to invest heavily in an application written by a new startup. Because it is such a sizable investment, you express your concerns about the longevity of the new company and the risk this organization is taking.

Access Control and Identity Management *Which of the three principles of security is supported by an iris biometric system?* a. Confidentiality b. Integrity c. Availability d. Vulnerability

a. *Confidentiality* Confidentiality involves protecting against unauthorized access, which biometric authentication systems support. Integrity is concerned with preventing unauthorized modification, making answer B incorrect. Answer C is not correct because availability is concerned with ensuring that access to services and data is protected against disruption. Answer D is incorrect because a vulnerability is a failure in one or more of the C-I-A principles.

*Which of the following should be implemented if the organization wants to monitor unauthorized transfers of confidential information?* a. Content inspection b. Proxy server c. Protocol analyzer d. Packet-filtering firewall

a. *Content inspection* Content inspection appliances use access control filtering software on a dedicated filtering appliance. The device monitors every packet of traffic that passes over a network. Answer B is incorrect. When a proxy server receives a request for an Internet service, it passes through filtering requirements and checks its local cache of previously downloaded web pages. Because web pages are stored locally, response times for web pages are faster and traffic to the Internet is substantially reduced. Answer C is incorrect. Protocol analyzers help you troubleshoot network issues by gathering packet-level information across the network. These applications capture packets and decode the information into readable data for analysis. Answer D is incorrect; a packet-filtering firewall filters packets based on IP addresses, ports, or protocols and is a simple, good first line of defense.

Access Control and Identity Management *In a decentralized key management system, the user is responsible for which one of the following functions?* a. Creation of the private and public key b. Creation of the digital certificate c. Creation of the CRL d. Revocation of the digital certificate

a. *Creation of the private and public key* In a decentralized key system, the end user generates his or her own key pair. The other functions, such as creation of the certificate, CRL, and the revocation of the certificate, are still handled by the certificate authority; therefore, answers B, C, and D are incorrect.

Access Control and Identity Management *The present method of requiring access to be strictly defined on every object is proving too cumbersome for your environment.

Although answers B and C are both types of DoS attacks, they are incorrect because DoS more accurately describes "a type of attack." Answer D is incorrect because social engineering describes the nontechnical means of obtaining information.

Threats and Vulnerabilities *Which type of attack denies authorized users access to network resources?*

a. *DoS* A DoS attack is intended to prevent access to network resources by overwhelming or flooding a service or network.

*You manage a network on which there are mixed vendor devices and are required to implement a strong authentication solution for wireless communications. Which of the following would best meet your requirements? (Select two correct answers.)* a. EAP b. WEP c. LEAP d. PEAP

a. *EAP* d. *PEAP* The IEEE and IETF specify 802.1X and EAP as the standard for secure wireless networking, and Protected EAP (PEAP) is standards based. PEAP was jointly developed by Microsoft, RSA Security, and Cisco Systems. It is an IETF open standard. PEAP provides mutual authentication and uses a certificate for server authentication by the client, and users have the convenience of entering password-based credentials. Answer B is incorrect because WEP is the most basic form of encryption that can be used on 802.11-based wireless networks to provide privacy of data sent between a wireless client and its access point. Answer C is incorrect because LEAP is a Cisco-proprietary protocol.

a. *Full disk encryption* Full disk encryption is most useful when you're dealing with machines that are being taken on the road by traveling executives, sales managers, or insurance agents. Answer B is incorrect because in file- or folder-level encryption, individual files or folders are encrypted by the file system itself. Answer C is incorrect because media encryption is used for USB flash drives, iPods, and other portable storage devices. Answer D is incorrect because application-level encryption does not protect the data stored on the machines.

Security-Related Policies and Procedures *The organization is concerned about vulnerabilities in commercial off-the-shelf (COTS) software. Which of the following might be the only means of reviewing the security quality of the program?* a. Fuzzing b. Cross-Site Scripting c. Input validation d. Cross-site request forgery

a. *Fuzzing* In some closed application instances, fuzzing might be the only means of reviewing the security quality of the program. Answer B is incorrect because Cross-Site Scripting (XSS) vulnerabilities can be used to hijack the user's session or to cause the user accessing malware-tainted Site A to unknowingly attack Site B on behalf of the attacker who planted code on Site A. Answer C is incorrect because input validation tests whether an application properly handles input from a source outside the application destined for internal processing. Answer D, Cross-site request forgery (XSRF), is an attack in which the end user executes unwanted actions on a web application while she is currently authenticated.

*Which of the following methods can be used to locate a device in the event it is lost or stolen?* a. GPS tracking b. Voice encryption c. Remote wipe d. Passcode policy

a. *GPS tracking* If a mobile device is lost, GPS tracking can be used to find the location. Answer B is incorrect because voice encryption can allow executives and employees alike to discuss sensitive information without having to travel to secure company locations.

a. *Implicit denial* The default assignment of an implicit denial, overridden by explicit grants of access aids in protecting resources against accidental access during normal network operations. Answer B is incorrect because least privilege is a principle of assigning only those rights necessary to perform assigned tasks. Answer C is incorrect because separation of duties is focused on ensuring that action and validation practices are performed separately. Answer D is incorrect because account expiration protocols ensure that individual accounts do not remain active past their designated lifespan, but they do nothing to protect against accidental resource availability for currently enabled accounts.

Disaster Recovery and Incident Response *Your organization is exploring data-loss prevention (DLP) solutions. The proposed solution is a software network solution that would be installed near the network perimeter to monitor for and flag policy violations. This solution is targeting which of the following data states?* a. In-transit b. At-rest c. In-use d. In-arrival

a. *In-transit* Protection of data in-transit is considered to be a network solution and either a hardware or software solution is installed near the network perimeter to monitor for and flag policy violations. Answer B is incorrect because protection of data at-rest is considered to be a storage solution and is generally a software solution that monitors how confidential data is stored. Answer C is incorrect because protection of data in-use is considered to be an endpoint solution and the application is run on end-user workstations or servers in the organization.

*Which of the following is not an example of multifactor authentication?* a. Logon and password b. Smart card and PIN c. RFID chip and thumbprint d. Gait and iris recognition e. Location and CAC

a. *Logon and password* Both logon and password represent a form of "what you know" authentication. Answers B, C, D, and E are all incorrect because they represent paired multifactor forms of authentication. A smart card and PIN represent what you have and know, and an RFID chip and thumbprint link what you have with what you are. Gait is a measure of what you do, and iris details are an example of what you are. Somewhere you are is a location, which could be based on GPS coordinates or IP address, and a common access card (CAC) is something you have.

*After a new switch was implemented, some sporadic connectivity issues on the network have occurred. The issues are suspected to be device related. Which of the following would the organization implement as a method for additional checks in order to prevent issues?* a. Loop protection b. Flood guard c. Implicit deny d. Port security

a. *Loop protection* The loop protection feature makes additional checks in Layer 2 switched networks. Answer B is incorrect because a flood guard is a firewall feature to control network activity associated with denial-of-service (DoS) attacks. Answer C is incorrect because implicit deny is an access control practice wherein resource availability is restricted to only those logons explicitly granted access. Answer D is incorrect because port security is a Layer 2 traffic control feature on Cisco Catalyst switches. It enables individual switch ports to be configured to allow only a specified number of source MAC addresses coming in through the port.

Access Control and Identity Management *Upper management has suddenly become concerned about security.

*Which password standard provides the best opportunity to detect and react to a high-speed, brute-force password attack?* a. Password length b. Account lockout c. Password expiration d. Logon banner

b. *Account lockout* By locking an account after a limited number of failed attempts, administrative action is necessary to unlock the account and can raise awareness of repeated unauthorized access attempts while reducing the overall number of tests that can be attempted. Answers A and C are incorrect because both password length and password expiration can aid in complicating slow brute-force testing of sequential passwords if performed only a few times per day to avoid notice, but they provide only limited protection against high-bandwidth, brute-force attempts to guess passwords. Password complexity (including mixed-case letters, numbers, and symbols) provides more protection than length alone because the number of variations possible for each character rapidly expands the number of total tests that must be completed. Answer D is incorrect because logon banners detail legal repercussions following unauthorized access but provide no barrier against a brute-force attack.

b. *Certificates are issued only at yearly intervals.* Digital certificates contain a field indicating the date to which the certificate is valid. This date is mandatory, and the validity period can vary from a short period of time up to a number of years; therefore, answers A, C, and D are incorrect.

*Which of the following provides a clear record of the path evidence takes from acquisition to disposal?* a. Video capture b. Chain of custody c. Hashes d. Witness statements

b. *Chain of custody* The chain of custody provides a clear record of the path evidence takes from acquisition to disposal. Answer A is incorrect because videotaping the actual entrance of a forensics team into the area helps refute claims that evidence was planted at the scene. Answer C is incorrect because hashes allow validation that the forensic analysis itself has not produced unexpected modifications of evidentiary data. Answer D is incorrect because witnesses provide statements about what they saw, when, where, and how.

Educating and Protecting the User *Users should be educated in the correct way to close pop-up ads in the workplace. That method is to:*

b. *Click the "X" in the top right* Pop-up ads should be closed by clicking the "X" in the top right.

*Which of the following best describes a host-based intrusion detection system (HIDS)?* a. Examines the information exchanged between machines b. Collects and analyzes data that originates on the local machine c. Controls the information coming in and out of the host machine d. Attempts to prevent network attacks in real time

b. *Collects and analyzes data that originates on the local machine* A host-based intrusion detection system (HIDS) collects and analyzes data that originates on the local machine. Answer A is incorrect; a network-based intrusion detection system (NIDS) tries to locate packets not allowed on the network that the firewall missed and looks at the information exchanged between machines. Answer C is incorrect because firewalls control the information that gets in and out of the host machine. Answer D is incorrect; intrusion prevention differs from intrusion detection in that it actually prevents attacks in real time instead of only detecting the occurrence.

Security-Related Policies and Procedures *The process of establishing boundaries for information sharing is called:* a. Disassociation b. Compartmentalization c. Isolation d. Segregation

b. *Compartmentalization* The process of establishing boundaries for information sharing is called compartmentalization.

b. *Core; workgroup* Core switches reside at the top of the hierarchy and carry traffic between switches, while workgroup switches are connected directly to the devices on the network.

Threats and Vulnerabilities *Which of the following types of attacks can be done by either convincing the users to click on an HTML page the attacker has constructed or insert arbitrary HTML in a target website that the users visit?* a. Buffer overflow b. Cross-site request forgery (XSRF) c. Cross-Site Scripting (XSS) d. Input validation error

b. *Cross-site request forgery (XSRF)* The key element to understanding XSRF is that attackers are betting that users have a validated login cookie for the website already stored in their browsers. All they need to do is get the browsers to make a request to the website on their behalf. This can be done by either convincing the users to click on an HTML page the attacker has constructed or inserting arbitrary HTML in a target website that the users visit. Answer A is incorrect because a buffer overflow is a direct result of poor or incorrect input validation or mishandled exceptions. Answer C is incorrect because Cross-Site Scripting (XSS) vulnerabilities can be used to hijack the user's session or to cause the user accessing malware-tainted Site A to unknowingly attack Site B on behalf of the attacker who planted code on Site A. Answer D is incorrect because input validation errors are a result of improper field checking in the code.

Security and Vulnerability in the Network *Adding a token for every POST or GET request that is initiated from the browser to the server can be used to mitigate which of the following attacks?* a. Buffer overflow b. Cross-site request forgery (XSRF) c. Cross-Site Scripting (XSS) d. Input validation error

b. *Cross-site request forgery (XSRF)* To mitigate cross-site request forgery (XSRF) attacks, the most common solution is to add a token for every POST or GET request that is initiated from the browser to the server. Answer A is incorrect because buffer overflows are associated with input validation. Answer C is incorrect because setting the HTTPOnly flag on the session cookie is used to mitigate XSS attacks. Answer D is incorrect because input validation tests whether an application properly handles input from a source outside the application destined for internal processing.

Access Control and Identity Management *Which form of access control enables data owners to extend access rights to other logons?* a. MAC b. DAC c. Role-based (RBAC) d. Rule-based (RBAC)

b. *DAC* Discretionary access control (DAC) systems enable data owners to extend access rights to other logons. Mandatory access control (MAC) systems require assignment of labels to extend access, making answer A incorrect. Answers C and D are incorrect because both RBAC access control forms rely on conditional assignment of access rules either inherited (role-based) or by environmental factors such as time of day or secured terminal location (rule-based).

Threats and Vulnerabilities *As the security administrator for your organization, you must be aware of all types of attacks that can occur and plan for them. Which type of attack uses more than one computer to attack the victim?*

b. *DDoS* A DDoS attack uses multiple computer systems to attack a server or host in the network.

*Which of the following is included in a BYOD policy?* a. Key management b. Data ownership c. Credential management d. Transitive trusts

b. *Data ownership* When formulating a bring-your-own-device (BYOD) policy, the organization should clearly state who owns the data stored on the device, specifically addressing what data belongs to the organization. Answer A is incorrect because key management is intended to provide a single point of management for keys, enable users to manage the lifecycle of keys and to store them securely, and make key distribution easier. Answer C is incorrect because the use of credentials is to validate the identities of users, applications, and devices. Answer D is incorrect because transitive trusts enable decentralized authentication through trusted agents.

*Which of the following is the formal process of assessing risk involved in discarding particular information?* a. Sanitization b. Declassification c. Degaussing d. Overwriting

b. *Declassification* Declassification is a formal process of assessing the risk involved in discarding particular information. Answer A is incorrect because sanitization is the process of removing the contents from the media as fully as possible, making it extremely difficult to restore. Answer C is incorrect because degaussing uses an electrical device to reduce the magnetic flux density of the storage media to zero. Answer D is incorrect because overwriting is applicable to magnetic storage devices and writes over all data on the media, destroying what was originally recorded.

Physical and Hardware-Based Security *If RF levels become too high, it can cause the receivers in wireless units to become deaf. This process is called:* a. Clipping b. Desensitizing c. Distorting d. Crackling

b. *Desensitizing* If RF levels become too high, it can cause the receivers in wireless units to become deaf and is known as desensitizing. This occurs because of the volume of RF energy present.

Cryptography Basics *Which of the following algorithms is not an example of a symmetric encryption algorithm?* a. Rijndael b. Diffie-Hellman c. RC6 d. AES

b. *Diffie-Hellman* Diffie-Hellman uses public and private keys, so it is considered an asymmetric encryption algorithm. Because Rijndael and Advanced Encryption Standard (AES) are now one in the same, they both can be called symmetric encryption algorithms; therefore, answers A and D are incorrect. Answer C is incorrect because RC6 is symmetric, too.

Operating System and Application Security *If an attacker is able to gain access to restricted directories (such as the root directory) through HTTP, it is known as:*

b. *Directory traversal* If an attacker is able to gain access to restricted directories (such as the root directory) through HTTP, it is known as directory traversal.

b. *Ensure Telnet is running* d. *Enable logging* Having Telnet enabled presents security issues and is not a primary method for minimizing threat. Logging is important for secure operations and is invaluable when recovering from a security incident. However, it is not a primary method for reducing threat. Answer A is incorrect because disabling all nonweb services might provide a secure solution for minimizing threats. Answer C is incorrect because each network service carries its own risks; therefore, it is important to disable all nonessential services.

Protecting Networks *Which of the following is the process in which a law enforcement officer or a government agent encourages or induces a person to commit a crime when the potential criminal expresses a desire not to go ahead?*

b. *Entrapment* Entrapment is the process in which a law enforcement officer or a government agent encourages or induces a person to commit a crime when the potential criminal expresses a desire not to go ahead.

*Which statement accurately describes a characteristic of FTP Secure (FTPS)?* a. FTPS is an entire protocol itself. b. FTPS is a combination of two technologies (FTP and SSL or TLS). c. FTPS uses a single TCP port. d. FTPS encrypts and compresses all data and commands.

b. *FTPS is a combination of two technologies (FTP and SSL or TLS).* There are several differences between SFTP and FTPS. First, FTPS is a combination of two technologies (FTP and SSL or TLS), whereas SFTP is an entire protocol itself and is not pieced together with multiple parts. Second, SFTP uses only a single TCP port instead of two ports like FTPS. Finally, SFTP encrypts and compresses all data and commands (FTPS may not encrypt data).

*Which element of business continuity planning (BCP) is most concerned with hot-site/cold-site planning?* a. Network connectivity b. Facilities c. Clustering d. Fault tolerance

b. *Facilities* Facilities continuity planning is focused around alternative site management, hardware, and service contracts. Network connectivity BCP involves establishing alternative network access paths and dedicated recovery administrative connections, making answer A incorrect. High-availability clustered servers ensure that automatic failover occurs in the event that the primary service nodes are unable to perform normal service functions, making answer C incorrect. Fault tolerance, particularly in the area of storage devices, supports individual server operational continuity in the face of hardware device failure, making answer D incorrect. In SAN storage systems, redundant storage network connections similarly ensure continuous resource access for devices in the storage-area network.

Security and Vulnerability in the Network *What are the two states that an application can fail in?* a. Dependable b. Failsafe c. Failopen d. Assured

b. *Failsafe* c. *Failopen* There are two states that an application can fail in. In a failsafe mode, the crash leaves the system secure. In a failopen state, the crash leaves the system exposed (not secure).

Security and Vulnerability in the Network *Which of the following is a protection feature built into many firewalls that allow the administrator to tweak the tolerance for unanswered login attacks?* a. MAC filter b. Flood guard c. MAC limiter d. Security posture

b. *Flood guard* A flood guard is a protection feature built into many firewalls that allow the administrator to tweak the tolerance for unanswered login attacks. By reducing this tolerance, it is possible to reduce the likelihood of a successful DoS attack.

Cryptography Basics *Which of the following is the type of algorithm used by MD5?* a. Block cipher algorithm b. Hashing algorithm c. Asymmetric encryption algorithm d. Cryptographic algorithm

b. *Hashing algorithm* Although the message digest (MD) series of algorithms is classified globally as a symmetric key encryption algorithm, the correct answer is hashing algorithm, which is the method that the algorithm uses to encrypt data. Answer A in incorrect because a block cipher divides the message into blocks of bits. Answer C is incorrect because MD5 is a symmetric key algorithm, not an asymmetric encryption algorithm (examples of this include RC6, Twofish, and Rijndael). Answer D is incorrect because cryptographic algorithm is a bogus term.

Network Security *Which statement concerning heuristic monitoring is correct?* a. Heuristic monitoring operates by being adaptive and proactive. b. Heuristic monitoring is founded on experience-based techniques. c. Heuristic monitoring is designed for detecting statistical anomalies. d. Heuristic monitoring looks for well-known patterns.

b. *Heuristic monitoring is founded on experience-based techniques.* Heuristic monitoring is founded on experience-based techniques. It attempts to answer the question, "Will this do something harmful if it is allowed to execute?"

*A CA with multiple subordinate CAs would use which of the following PKI trust models?* a. Cross-certified b. Hierarchical c. Bridge d. Linked

b. *Hierarchical* A DMZ is a small network between the internal network and the Internet that provides a layer of security and privacy. Answer A is incorrect. The purpose of a VLAN is to unite network nodes logically into the same broadcast domain regardless of their physical attachment to the network. Answer C is incorrect because NAT acts as a liaison between an internal network and the Internet. Answer D is incorrect because a VPN is a network connection that allows you access via a secure tunnel created through an Internet connection.

Educating and Protecting the User *There are two types of implicit denies. One of these can be configured so that only users specifically named can use the service and is known as:*

b. *at.allow* at.allow configurations allow only users specifically named to use the service.

*Which of the following describes a network of systems designed to lure an attacker away from another critical system?* a. Bastion host b. Honeynet c. Vulnerability system d. Intrusion-detection system

b. *Honeynet* Honeynets are collections of honeypot systems interconnected to create networks that appear to be functional and that can be used to study an attacker's behavior within the network. A bastion host is the first line of security that a company allows to be addressed directly from the Internet; therefore, answer A is incorrect. Answer C is incorrect because it is a made-up term. Answer D is incorrect because an IDS is used for intrusion detection.

*Which protocol is the standard protocol for Internet usage?* a. Internet Control Message Protocol (ICMP) b. Hypertext Transport Protocol (HTTP) c. Network Basic Input/Output System (NetBIOS) d. Secure Network Management Protocol (SNMP)

b. *Hypertext Transport Protocol (HTTP)* Hypertext Transport Protocol (HTTP), which is the standard protocol for Internet usage.

*Which of the fields included within a digital certificate identifies the directory name of the entity signing the certificate?* a. Signature algorithm identifier b. Issuer c. Subject name d. Subject public key information

b. *Issuer* The Issuer field identifies the name of the entity signing the certificate, which is usually a certificate authority. The Signature Algorithm Identifier identifies the cryptographic algorithm used by the CA to sign the certificate; therefore, answer A is incorrect. The Subject Name is the name of the end entity identified in the public key associated with the certificate; therefore, answer C is incorrect. The Subject Public Key Information field includes the public key of the entity named in the certificate, including a cryptographic algorithm identifier; therefore, answer D is incorrect.

*Which type of authorization provides a mechanism for validation of both sender and receiver?* a. Anonymous b. Kerberos c. TACACS d. RADIUS

b. *Kerberos* Kerberos authentication enables validation of both endpoints and can help protect against interception attacks such as the "man-in-the-middle." Anonymous connections do not even allow verification of the access requestor, making answer A incorrect. Answers C and D are incorrect because neither TACACS or RADIUS services provide mutual endpoint validation.

Access Control and Identity Management *You've been assigned to mentor a junior administrator and bring him up to speed quickly. The topic you're currently explaining is authentication. Which method uses a KDC to accomplish authentication for users, programs, or systems?*

b. *authentication* The IEEE 802.1x standard provides the highest degree of port security by implementing port-based authentication.

*Which risk reduction policy does not aid in identifying internal fraud?* a. Mandatory vacations b. Least privilege c. Separation of duties d. Job rotation

b. *Least privilege* Although least privilege can aid in protecting against internal fraud, it does not particularly aid in identifying it if occurring. Mandatory vacations, job rotation, and separation of duties such as monetary processing and validation all provide cross-checks that can aid in the identification of ongoing fraudulent operations, making answers A, C, and D incorrect.

*Lynn needs access to the Accounting order-entry application but keeps getting an error that indicates inadequate access permissions. Bob assigns Lynn's account to the Administrator's group to overcome the error until he can work on the problem. Which access control constraint was violated by this action?* a. Implicit denial b. Least privilege c. Separation of duties d. Account expiration

b. *Least privilege* Least privilege is a principle of assigning only those rights necessary to perform assigned tasks. By making Lynn a member of the Administrators group, Bob not only bypassed the application's access control protocols but may also have granted Lynn access to additional application features or administrative-only tools that often lack the same safeguards as user-level APIs. Answer A is incorrect because the default assignment of an implicit denial is overridden by explicit grants of access aids in protecting resources against accidental access and is not directly violated by this action because Lynn's account now has full administrator rights assigned. Answer C is incorrect because separation of duties is focused on ensuring that action and validation practices are performed separately. Answer D is incorrect because account expiration protocols ensure that individual accounts do not remain active past their designated lifespan, but Lynn's account is current and enabled so is unaffected.

*Which of the following is not a common quality of quantitative risk analysis?* a. Difficult for management to understand b. Less precise c. Labor intensive d. Time-consuming

b. *Less precise* Qualitative risk assessments tend to be less precise than quantitative assessments. Quantitative risk assessments tend to be more difficult for management to understand properly without additional explanation, require intensive labor to gather all of the necessary measurements, and are time-consuming to produce and keep up to date, making answers A, C, and D incorrect.

Physical and Hardware-Based Security *For physical security, what should you do with rack-mounted servers?* a. Run a cable from them to a desk. b. Lock each of them into the cabinet. c. Install them in safes. d. Use only Type D, which incorporates its own security.

*Which of the following is not one of the vulnerabilities of LDAP authentication services?* a. Buffer overflow vulnerabilities can be used to enact arbitrary commands on the LDAP server. b. Loss of time synchronization between the service, client, and KDC prevents communication. c. Format string vulnerabilities might result in unauthorized access to enact commands on the LDAP server or impair its normal operation. d. Improperly formatted requests might be used to create an effective denial-of-service (DoS) attack against the LDAP server.

b. *Loss of time synchronization between the service, client, and KDC prevents communication.* Kerberos is a time-synchronized protocol that relies on a common time base for session ticket lifetime verification. LDAP is not a ticket-based or a lifetime-based protocol. Answers A, C, and D are incorrect because all three are vulnerabilities of some LDAP service variations.

Security and Vulnerability in the Network *An organization is looking for a filtering solution that will help eliminate some of the recent problems it has had with viruses and worms. Which of the following best meets this requirement?* a. Intrusion detection b. Malware inspection c. Load balancing d. Internet content filtering

b. *Malware inspection* A malware inspection filter is basically a web filter applied to traffic that uses HTTP. The body of all HTTP requests and responses is inspected. Malicious content is blocked, but legitimate content passes through unaltered. Answer A is incorrect because intrusion-detection systems are designed to analyze data, identify attacks, and respond to the intrusion. Answer C is incorrect because load balancers are servers configured in a cluster to provide scalability and high availability. Answer D is incorrect because Internet content filters use a collection of terms, words, and phrases that are compared to content from browsers and applications.

Operating System and Application Security *Which of the following is needed to establish effective security baselines for host systems? (Select two correct answers.)* a. Cable locks b. Mandatory settings c. Standard application suites d. Decentralized administration

b. *Mandatory settings* c. *Standard application suites* To establish effective security baselines, enterprise network security management requires a measure of commonality between the systems. Mandatory settings, standard application suites, and initial setup configuration details all factor into the security stance of an enterprise network. Answer A is incorrect because cable locks have nothing to do with effective security baselines. Answer D is incorrect because decentralized management does not have anything to do with security baselines.

*What is the most common type of wireless access control?* a. Electronic Access Control (EAC) b. Media Access Control (MAC) address filtering c. Extensible Authentication Protocol-Transport Layer Security (EAP/TLS) d. Port Based Access Control (PBAC)

b. *Media Access Control (MAC) address filtering* The most common type of wireless access control is Media Access Control (MAC) address filtering. The MAC address is a hardware address that uniquely identifies each node of a network.

*The most effective means to reduce the risk of losing the data on a mobile device, such as a notebook computer, is _____.*

b. *Minimize sensitive data stored on the mobile device.* The risk of a lost or stolen notebook is the data loss, not the loss of the system itself. Thus, keeping minimal sensitive data on the system is the only way to reduce the risk. Hard-drive encryption, cable locks, and strong passwords, although good ideas, are preventative tools, not means of reducing risk. They don't keep intentional and malicious data compromise from occurring; instead, they encourage honest people to stay honest.

Cryptography Basics *Assuming asymmetric encryption, if data is encoded with a value of 5, what would be used to decode it?*

c. *1/5* With asymmetric encryption, two keys are used—one to encode and the other to decode. The two keys are mathematical reciprocals of each other.

*What technology provides an organization with the best control over BYOD equipment?* a. Encrypted removable storage b. Mobile device management c. Geo-tagging d. Application whitelisting

b. *Mobile device management* Mobile device management (MDM) is a software solution to the challenging task of managing the myriad mobile devices that employees use to access company resources. The goals of MDM are to improve security, provide monitoring, enable remote management, and support troubleshooting.

*Which of the following is considered best practice when formulating minimum standards for developing password policies?* a. Password length set to 6 characters b. Require password change at 90 days c. Maximum password age set to zero d. Account lockout threshold set to zero

b. *Require password change at 90 days* Require users to change passwords every 90 to 180 days, depending on how secure the environment needs to be. Remember that the more often users are required to change passwords, the greater the chance that they will write them down, potentially exposing them to unauthorized use. Answer A is incorrect because making the password length at least eight characters and requiring the use of combinations of uppercase and lowercase letters, numbers, and special characters is good practice. Answer C is incorrect because good policy is to set the maximum password age to a value between 30 and 90 days. Answer D is incorrect because if the lockout threshold is set to zero, accounts will not be locked out due to invalid logon attempts.

c. *Implement use of a one-time use token* Although both A and B provide controls for passwords, they are still both based on something the user knows: a password. A one-time use token can be a dedicated hardware token or may be a software token or text message on a mobile device. This would be an example of something the user has (for example, a hardware token or registered mobile device). Answer D is incorrect.

Access Control and Identity Management *What is implied at the end of each access control list?*

c. *Implicit deny* An implicit deny clause is implied at the end of each ACL, and it means that if the proviso in question has not been explicitly granted, then it is denied.

* _______________ in access control means that if a condition is not explicitly met, the request for access is rejected.* a. Static allow b. Explicit allow c. Implicit deny d. Dynamic deny

c. *Implicit deny* Implicit deny in access control means that if a condition is not explicitly met, the request for access is rejected. (Implicit means that something is implied or indicated but not actually expressed.)

*An organization has an access control list implemented on the border router, but it appears that unauthorized traffic is still being accepted. Which of the following would the organization implement to improve the blocking of unauthorized traffic?* a. Loop protection b. Flood guard c. Implicit deny d. Port security

c. *Implicit deny* Implicit deny is an access control practice wherein resource availability is restricted to only those logons explicitly granted access. Answer A is incorrect because the loop protection feature makes additional checks in Layer 2 switched networks. Answer B is incorrect because a flood guard is a firewall feature to control network activity associated with denial-of-service (DoS) attacks.

c. *Network segmentation* With interconnected networks, the potential for damage greatly increases because one compromised system on one network can easily spread to other networks. Networks that are shared by partners, vendors, or departments should have clear separation boundaries. Answer A is incorrect because a captive portal is used to block Internet access for users until some action is taken. Answer B is incorrect because access control generally refers to the process of making resources available to accounts that should have access, while limiting that access to only what is required. Answer D is incorrect because logging is the process of collecting data to be used for monitoring and auditing purposes.

*Which of the following is a security concern when implementing NoSQL databases?* a. NoSQL databases do not provide any authentication mechanisms. b. The NoSQL design uses server-side validation. c. NoSQL databases lack confidentiality and integrity. d. NoSQL databases are lacking in areas of scalability and performance.

c. *NoSQL databases lack confidentiality and integrity.* The NoSQL design does not place security as a high priority, lacking confidentiality and integrity. Answer A is incorrect because NoSQL databases such as MongoDB have added support for Kerberos authentication, more granular access controls, and SSL encryption. Answer B is incorrect because server-side validation helps protect against malicious attempts by a user to bypass validation or submit unsafe input and it is associated with web-based applications not databases. Answer D is incorrect because when compared to relational databases, NoSQL systems are more scalable and provide superior performance. Scalability and performance are not security concerns.

Cryptography Basics *What is the acronym for the de facto cryptographic message standards developed by RSA Laboratories?* a. PKIX b. X.509 c. PKCS d. Both A and C

Disaster Recovery and Incident Response *Which of the following designates the amount of data loss that is sustainable and up to what point in time data recovery could happen before business is disrupted?* a. RTO b. MTBF c. RPO d. MTTF

c. *RPO* Recovery point objective (RPO) is the amount of time that can elapse during a disruption before the quantity of data lost during that period exceeds the BCP's maximum allowable threshold. Simply put, RPO specifies the allowable data loss. It determines up to what point in time data recovery could happen before business is disrupted. Answer A is incorrect because recovery time objective (RTO) is the amount of time within which a process must be restored after a disaster to meet business continuity. It defines how much time it takes to recover after notification of process disruption. Answer B is incorrect because mean time between failures (MTBF) is the average amount of time that passes between hardware component failures excluding time spent waiting for or being repaired. Answer D is incorrect because mean time to failure (MTTF) is the length of time a device or product is expected to last in operation.

An MOU is not typically a legal agreement or commitment, but rather a more formal form of a reciprocal agreement or gentleman's handshake (neither of which is typically written down). An SLA is a formal control. BIA is business impact assessment. DLP is data loss prevention.

*Which of the following is the length of time a device or product is expected to last in operation?* a. RTO b. MTBF c. RPO d. MTTF

d. *MTTF* Mean time to failure (MTTF) is the length of time a device or product is expected to last in operation. Answer A is incorrect because recovery time objective (RTO) is the amount of time within which a process must be restored after a disaster to meet business continuity. It defines how much time it takes to recover after notification of process disruption. Answer B is incorrect because mean time between failures (MTBF) is the average amount of time that passes between hardware component failures excluding time spent waiting for or being repaired. Answer C is incorrect because recovery point objective (RPO) is the amount of time that can elapse during a disruption before the quantity of data lost during that period exceeds the BCP's maximum allowable threshold. It determines up to what point in time data recovery could happen before business is disrupted.

Access Control and Identity Management *If Sally wants to send a secure message to Mark using public key encryption but is not worried about sender verification, what does she need in addition to her original message text?* a.

The power can be adjusted to provide a cleaner signal with less interference. c. The power can be adjusted so that more of the signal leaves the premises and reaches outsiders. d. The power can be adjusted so that less of the signal leaves the premises and reaches outsiders.

d. *The power can be adjusted so that less of the signal leaves the premises and reaches outsiders.* A security feature on some APs is the ability to adjust the level of power at which the WLAN transmits. On devices with that feature, the power can be adjusted so that less of the signal leaves the premises and reaches outsiders.

Cryptography Basics *Which of the following best describes the process of encrypting and decrypting data using an asymmetric encryption algorithm?* a. Only the public key is used to encrypt, and only the private key is used to decrypt. b. The public key is used to either encrypt or decrypt. c. Only the private key is used to encrypt, and only the public key is used to decrypt. d. The private key is used to decrypt data encrypted with the public key.

d. *The private key is used to decrypt data encrypted with the public key.* When encrypting and decrypting data using an asymmetric encryption algorithm, you use only the private key to decrypt data encrypted with the public key. Answers A and B are both incorrect because in public key encryption, if one key is used to encrypt, you can use the other to decrypt the data. Answer C is incorrect because the public key is not used to decrypt the same data it encrypted.

*Users received a spam email from an unknown source and chose the option in the email to unsubscribe and are now getting more spam as a result. Which one of the following is most likely the reason?* a. The unsubscribe option does not actually do anything. b. The unsubscribe request was never received. c. Spam filters were automatically turned off when making the selection to unsubscribe. d. They confirmed that their addresses are "live."

d. *They confirmed that their addresses are "live."* Often an option to opt out of further email does not unsubscribe users; instead it means, "send me more spam" because it has been confirmed that the email address is not dormant. This is less likely to occur with email a user receives that he or she opted into in the first place, however. Answers A, B, and C are incorrect because these are less likely and not the best choices.

Access Control and Identity Management *Which is the best rule-based access control constraint to protect against unauthorized access when admins are off-duty?* a. Least privilege b. Separation of duties c. Account expiration d. Time of day

d. *Time of day* Time-of-day rules prevent administrative access requests during off-hours when local admins and security professionals are not on duty. Answer A is incorrect because least privilege is a principle of assigning only those rights necessary to perform assigned tasks. Answer B is incorrect because separation of duties aids in identification of fraudulent or incorrect processes by ensuring that action and validation practices are performed separately. Answer C is incorrect because account expiration policies ensure that individual accounts do not remain active past their designated lifespan but do nothing to ensure protections are enabled during admin downtime.

Network Security *What is the role of a switch?* a. To inspect packets and either accept or deny entry b. To forward packets across different network computer networks c. To intercept user requests from the internal secure network and then process that request on behalf of the user d. To connect networks together so that they function as a single network segment

d. *To connect networks together so that they function as a single network segment* Early local area networks (LANs) used a hub, which is a standard network device for connecting multiple network devices together so that they function as a single network segment. A network switch is a device that connects network devices together. However, unlike a hub, a switch has a degree of "intelligence."

Network Security *What is the primary role of a firewall?* a. To forward packets across different network computer networks b. To intercept user requests from the internal secure network and then process that request on behalf of the user c. To connect networks together so that they function as a single network segment d. To inspect packets and either accept or deny entry

d. *To inspect packets and either accept or deny entry* Although a host-based application software firewall that runs as a program on one client is different from a hardware-based network firewall designed to protect an entire network, their functions are essentially the same: to inspect packets and either accept or deny entry.

*Several organizational users are experiencing network and Internet connectivity issues. Which of the following would be most helpful in troubleshooting where the connectivity problems might exist?* a. SSL b. IPsec c. SNMP d. Traceroute

d. *Traceroute* Traceroute uses an ICMP echo request packet to find the path between two addresses.

Whaling uses SMS, whereas phishing uses email. d. Whaling is similar to phishing but specifically targets high-profile individuals.

d. *Whaling is similar to phishing but specifically targets high-profile individuals.* Whaling specifically targets high-profile individuals. Phishing attempts to acquire sensitive information from anyone. Although they are very similar, they differ in the scope of the target, making answer A incorrect. Answer B is incorrect and refers to vishing, which is essentially phishing but using the phone. Answer C is incorrect as this describes smishing, which uses Short Message Service (SMS), or text messaging.

*When is business continuity needed?* a. When new software is distributed b. When business processes are interrupted c. When a user steals company data d. When business processes are threatened
