Which of the following allows a company to maintain access to encrypted resources when employee turnover is high? A. Recovery agent B. Certificate authority C. Trust model D. Key escrow
Answer: A Explanation: If an employee leaves and we need access to data he has encrypted, we can use the key recovery agent to retrieve his decryption key. We can use this recovered key to access the data. A key recovery agent is an entity that has the ability to recover a key, key components, or plaintext messages as needed. As opposed to escrow, recovery agents are typically used to access information that is encrypted with older keys.
Which of the following relies on the use of shared secrets to protect communication? A. RADIUS B. Kerberos C. PKI D. LDAP
Answer: A Explanation: Obfuscated passwords are transmitted by the RADIUS protocol via a shared secret and the MD5 hashing algorithm.
After working on his doctoral dissertation for two years, Peter, a user, is unable to open his dissertation file. The screen shows a warning that the dissertation file is corrupted because it is infected with a backdoor, and can only be recovered by upgrading the antivirus software from the free version to the commercial version. Which of the following types of malware is the laptop MOST likely infected with? A. Ransomware B. Trojan C. Backdoor D. Armored virus
Answer: A Explanation: Ransomware is a type of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator(s) of the malware in order for the restriction to be removed. Some forms of ransomware encrypt files on the system's hard drive), while some may simply lock the system and display messages intended to coax the user into paying. Ransomware typically propagates as a trojan like a conventional computer worm, entering a system through, for example, a downloaded file or a vulnerability in a network service. The program will then run a payload: such as one that will begin to encrypt personal files on the hard drive. More sophisticated ransomware may hybrid-encrypt the victim's plaintext with a random symmetric key and a fixed public key. The malware author is the only party that knows the needed private decryption key. Some ransomware payloads do not use encryption. In these cases, the payload is simply an application designed to restrict interaction with the system, typically by setting the Windows Shell to itself, or even modifying the master boot record and/or partition table (which prevents the operating system from booting at all until it is repaired) Ransomware payloads utilize elements of scareware to extort money from the system's user. The payload may, for example, display notices purportedly issued by companies or law enforcement agencies which falsely claim that the system had been used for illegal activities, or contains illegal content such as pornography and pirated software or media. Some ransomware payloads imitate Windows' product activation notices, falsely claiming that their computer's Windows installation is counterfeit or requires re-activation. These tactics coax the user into paying the malware's author to remove the ransomware, either by supplying a program which can decrypt the files, or by sending an unlock code that undoes the changes the payload has made.
After reviewing the firewall logs of her organization's wireless APs, Ann discovers an unusually high amount of failed authentication attempts in a particular segment of the building. She remembers that a new business moved into the office space across the street. Which of the following would be the BEST option to begin addressing the issue? A. Reduce the power level of the AP on the network segment B. Implement MAC filtering on the AP of the affected segment C. Perform a site survey to see what has changed on the segment D. Change the WPA2 encryption key of the AP in the affected segment
Answer: A Explanation: Some access points include power level controls that allow you to reduce the amount of output provided if the signal is traveling too far.
A security administrator wants to deploy security controls to mitigate the threat of company employees' personal information being captured online. Which of the following would BEST serve this purpose? A. Anti-spyware B. Antivirus C. Host-based firewall D. Web content filter

An internal audit has detected that a number of archived tapes are missing from secured storage. There was no recent need for restoration of data from the missing tapes. The location is monitored by access control and CCTV systems. Review of the CCTV system indicates that it has not been recording for three months. The access control system shows numerous valid entries into the storage location during that time. The last audit was six months ago and the tapes were accounted for at that time. Which of the following could have aided the investigation? A. Testing controls B. Risk assessment C. Signed AUP D. Routine audits
Answer: A Explanation: Testing controls come in three types: Technical, Management and Operational. In this question, the CCTV system has not been recording for three months and no one noticed. Improved testing controls (regular testing to verify the CCTV system is recording) would ensure that the CCTV is recording as expected. The CCTV recordings could have aided the investigation into the missing tapes. Topic 4, Application, Data and Host Security
Which of the following types of application attacks would be used to identify malware causing security breaches that have NOT yet been identified by any trusted sources? A. Zero-day B. LDAP injection C. XML injection D. Directory traversal
Answer: A Explanation: The security breaches have NOT yet been identified. This is zero day vulnerability. A zero day vulnerability refers to a hole in software that is unknown to the vendor. This security hole is then exploited by hackers before the vendor becomes aware and hurries to fix it—this exploit is called a zero day attack. Uses of zero day attacks can include infiltrating malware, spyware or allowing unwanted access to user information. The term "zero day" refers to the unknown nature of the hole to those outside of the hackers, specifically, the developers. Once the vulnerability becomes known, a race begins for the developer, who must protect users.
Ann, the security administrator, received a report from the security technician, that an unauthorized new user account was added to the server over two weeks ago. Which of the following could have mitigated this event? A. Routine log audits B. Job rotation C. Risk likelihood assessment D. Separation of duties

A process in which the functionality of an application is tested without any knowledge of the internal mechanisms of the application is known as: A. Black box testing B. White box testing C. Black hat testing D. Gray box testing
Answer: A Explanation: Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied to virtually every level of software testing: unit, integration, system and acceptance. It typically comprises most if not all higher level testing, but can also dominate unit testing as well. Specific knowledge of the application's code/internal structure and programming knowledge in general is not required. The tester is aware of what the software is supposed to do but is not aware of how it does it. For instance, the tester is aware that a particular input returns a certain, invariable output but is not aware of how the software produces the output in the first place.
The security consultant is assigned to test a client's new software for security, after logs show targeted attacks from the Internet. To determine the weaknesses, the consultant has no access to the application program interfaces, code, or data structures. This is an example of which of the following types of testing? A. Black box B. Penetration C. Gray box D. White box
Answer: A Explanation: Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied to virtually every level of software testing: unit, integration, system and acceptance. It typically comprises most if not all higher level testing, but can also dominate unit testing as well. Specific knowledge of the application's code/internal structure and programming knowledge in general is not required. The tester is aware of what the software is supposed to do but is not aware of how it does it. For instance, the tester is aware that a particular input returns a certain, invariable output but is not aware of how the software produces the output in the first place.
A computer security officer has investigated a possible data breach and has found it credible. The officer notifies the data center manager and the Chief Information Security Officer (CISO). This is an example of: A. escalation and notification. B. first responder. C. incident identification. D. incident mitigation.
Answer: A Explanation: Escalation and notification is a response strategy that outlines a staged procedure of escalation and notification that is to be followed in the event of a security incident. Only those in specific positions of authority or responsibility must receive notification of the security breach.
Which of the following helps to apply the proper security controls to information? A. Data classification B. Deduplication C. Clean desk policy D. Encryption

Input validation is an important security defense because it: A. rejects bad or malformed data. B. enables verbose error reporting. C. protects mis-configured web servers. D. prevents denial of service attacks.
Answer: A Explanation: Input validation is a defensive technique intended to mitigate against possible user input attacks, such as buffer overflows and fuzzing. Input validation checks every user input submitted to the application before processing that input. The check could be a length, a character type, a language type, or a domain.
A network engineer is designing a secure tunneled VPN. Which of the following protocols would be the MOST secure? A. IPsec B. SFTP C. BGP D. PPTP
Answer: A Explanation: Layer 2 Tunneling Protocol (L2TP) came about through a partnership between Cisco and Microsoft with the intention of providing a more secure VPN protocol. L2TP is considered to be a more secure option than PPTP, as the IPSec protocol which holds more secure encryption algorithms, is utilized in conjunction with it. It also requires a pre-shared certificate or key. L2TP's strongest level of encryption makes use of 168 bit keys, 3 DES encryption algorithm and requires two levels of authentication. L2TP has a number of advantages in comparison to PPTP in terms of providing data integrity and authentication of origin verification designed to keep hackers from compromising the system. However, the increased overhead required to manage this elevated security means that it performs at a slower pace than PPTP.
A company uses PGP to ensure that sensitive email is protected. Which of the following types of cryptography is being used here for the key exchange? A. Symmetric B. Session-based C. Hashing D. Asymmetric
Answer: A Explanation: PGP combines symmetric-key encryption and public-key encryption. The message is encrypted using a symmetric encryption algorithm, which requires a symmetric key. Each symmetric key is used only once and is also called a session key.
Which of the following encompasses application patch management? A. Configuration management B. Policy management C. Cross-site request forgery D. Fuzzing
Answer: A Explanation: Patch management is the process of maintaining the latest source code for applications and operating systems by applying the latest vendor updates. This helps protect a systems from newly discovered attacks and vulnerabilities. A part of patch management is testing the effects of vendor updates on a test system first to ensure that the updates do not have detrimental effects on the system and its configuration, and, should the updates have no detrimental effects on the test systems, backing up the production systems before applying the updates on a production system.
End-user awareness training for handling sensitive personally identifiable information would include secure storage and transmission of customer: A. Date of birth. B. First and last name. C. Phone number. D. Employer name.
Answer: A Explanation: Personally identifiable information (PII) is a catchall for any data that can be used to uniquely identify an individual. This data can be anything from the person's name to a fingerprint (think biometrics), credit card number, or patient record. Date of birth is personally identifiable information.
Which of the following BEST describes a SQL Injection attack? A. The attacker attempts to have the receiving server pass information to a back-end database from which it can compromise the stored information. B. The attacker attempts to have the receiving server run a payload using programming commonly found on web servers. C. The attacker overwhelms a system or application, causing it to crash and bring the server down to cause an outage. D. The attacker overwhelms a system or application, causing it to crash, and then redirects the memory address to read from a location holding the payload.
Answer: A Explanation: SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). SQL injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database.
Human Resources suspect an employee is accessing the employee salary database. The administrator is asked to find out who it is. In order to complete this task, which of the following is a security control that should be in place? A. Shared accounts should be prohibited. B. Account lockout should be enabled C. Privileges should be assigned to groups rather than individuals D. Time of day restrictions should be in use
Answer: A Explanation: Since distinguishing between the actions of one person and another isn't possible if they both use a shared account, shared accounts should not be allowed. If shared accounts are being used, the administrator will find the account, but have more than one suspect. To nullify this occurrence, Shared accounts should be prohibited.
A recent spike in virus detections has been attributed to end-users visiting www.compnay.com. The business has an established relationship with an organization using the URL of www.company.com but not with the site that has been causing the infections. Which of the following would BEST describe this type of attack? A. Typo squatting B. Session hijacking C. Cross-site scripting D. Spear phishing
Answer: A Explanation: Typosquatting, also called URL hijacking or fake url, is a form of cybersquatting, and possibly brandjacking which relies on mistakes such as typographical errors made by Internet users when inputting a website address into a web browser. Should a user accidentally enter an incorrect website address, they may be led to any URL (including an alternative website owned by a cybersquatter). The typosquatter's URL will usually be one of four kinds, all similar to the victim site address: (In the following, the intended website is "example.com") A common misspelling, or foreign language spelling, of the intended site: exemple.com A misspelling based on typing errors: xample.com or examlpe.com A differently phrased domain name: examples.com A different top-level domain: example.org Once in the typosquatter's site, the user may also be tricked into thinking that they are in fact in the real site; through the use of copied or similar logos, website layouts or content.
Jane has recently implemented a new network design at her organization and wishes to passively identify security issues with the new network. Which of the following should Jane perform? A. Vulnerability assessment B. Black box testing C. White box testing D. Penetration testing
Answer: A Explanation: Vulnerability scanning has minimal impact on network resources due to the passive nature of the scanning. A vulnerability scan is the process of scanning the network and/or I.T. infrastructure for threats and vulnerabilities. The threats and vulnerabilities are then evaluated in a risk assessment and the necessary actions taken to resolve and vulnerabilities. A vulnerability scan scans for known weaknesses such as missing patches or security updates. A vulnerability scan is the automated process of proactively identifying security vulnerabilities of computing systems in a network in order to determine if and where a system can be exploited and/or threatened. While public servers are important for communication and data transfer over the Internet, they open the door to potential security breaches by threat agents, such as malicious hackers. Vulnerability scanning employs software that seeks out security flaws based on a database of known flaws, testing systems for the occurrence of these flaws and generating a report of the findings that an individual or an enterprise can use to tighten the network's security.
How must user accounts for exiting employees be handled? A. Disabled, regardless of the circumstances B. Disabled if the employee has been terminated C. Deleted, regardless of the circumstances D. Deleted if the employee has been terminated
Answer: A Explanation: You should always disable an employee's account as soon as they leave. The employee knows the username and password of the account and could continue to log in for potentially malicious purposes. Disabling the account will ensure that no one can log in using that account.

When using PGP, which of the following should the end user protect from compromise? (Select TWO). A. Private key B. CRL details C. Public key D. Key password E. Key escrow F. Recovery agent
Answer: A,D Explanation: A: In PGP only the private key belonging to the receiver can decrypt the session key. PGP combines symmetric-key encryption and public-key encryption. The message is encrypted using a symmetric encryption algorithm, which requires a symmetric key. Each symmetric key is used only once and is also called a session key. D: PGP uses a passphrase to encrypt your private key on your machine. Your private key is encrypted on your disk using a hash of your passphrase as the secret key. You use the passphrase to decrypt and use your private key.
The loss prevention department has purchased a new application that allows the employees to monitor the alarm systems at remote locations. However, the application fails to connect to the vendor's server and the users are unable to log in. Which of the following are the MOST likely causes of this issue? (Select TWO). A. URL filtering B. Role-based access controls C. MAC filtering D. Port Security E. Firewall rules
Answer: A,E Explanation: A URL filter is used to block URLs (websites) to prevent users accessing the website. Firewall rules act like ACLs, and they are used to dictate what traffic can pass between the firewall and the internal network. Three possible actions can be taken based on the rule's criteria: Block the connection Allow the connection Allow the connection only if it is secured Incorrect Options: B: Role-based Access Control is basically based on a user's job description. When a user is assigned a specific role in an environment, that user's access to objects is granted based on the required tasks of that role. Since the sales team needs to save and print reports, they would not be restricted if restrictions were role-based. C: A MAC filter is a list of authorized wireless client interface MAC addresses that is used by a WAP to block access to all unauthorized devices. D: Port security works at level 2 of the OSI model and allows an administrator to configure switch ports so that only certain MAC addresses can use the port.

A company is looking to reduce the likelihood of employees in the finance department being involved with money laundering. Which of the following controls would BEST mitigate this risk? A. Implement privacy policies B. Enforce mandatory vacations C. Implement a security policy D. Enforce time of day restrictions
Answer: B Explanation: A mandatory vacation policy requires all users to take time away from work to refresh. And in the same time it also gives the company a chance to make sure that others can fill in any gaps in skills and satisfy the need to have replication or duplication at all levels in addition to affording the company an opportunity to discover fraud for when others do the same job in the absence of the regular staff member then there is transparency.
Which of the following can only be mitigated through the use of technical controls rather that user security training? A. Shoulder surfing B. Zero-day C. Vishing D. Trojans
Answer: B Explanation: A zero day vulnerability is an unknown vulnerability in a software application. This cannot be prevented by user security training. A zero day vulnerability refers to a hole in software that is unknown to the vendor. This security hole is then exploited by hackers before the vendor becomes aware and hurries to fix it—this exploit is called a zero day attack. Uses of zero day attacks can include infiltrating malware, spyware or allowing unwanted access to user information. The term "zero day" refers to the unknown nature of the hole to those outside of the hackers, specifically, the developers. Once the vulnerability becomes known, a race begins for the developer, who must protect users.

Which statement BEST describes her privileges? A. All users have write access to the directory. B. Jane has read access to the file. C. All users have read access to the file. D. Jane has read access to the directory.
Answer: C Explanation: The question states that Jane was able to download a document from the spool directory. To view and download the document, Jane must have at least Read access to the file. The fact that the document belonged to someone else suggests that all users have read access to the file.
Data execution prevention is a feature in most operating systems intended to protect against which type of attack? A. Cross-site scripting B. Buffer overflow C. Header manipulation D. SQL injection
Answer: B Explanation: Data Execution Prevention (DEP) is a security feature included in modern operating systems. It marks areas of memory as either "executable" or "nonexecutable", and allows only data in an "executable" area to be run by programs, services, device drivers, etc. It is known to be available in Linux, OS X, Microsoft Windows, iOS and Android operating systems. DEP protects against some program errors, and helps prevent certain malicious exploits, especially attacks that store executable instructions in a data area via a buffer overflow. A buffer overflow occurs when a program or process tries to store more data in a buffer (temporary data storage area) than it was intended to hold. Since buffers are created to contain a finite amount of data, the extra information - which has to go somewhere - can overflow into adjacent buffers, corrupting or overwriting the valid data held in them. Although it may occur accidentally through programming error, buffer overflow is an increasingly common type of security attack on data integrity. In buffer overflow attacks, the extra data may contain codes designed to trigger specific actions, in effect sending new instructions to the attacked computer that could, for example, damage the user's files, change data, or disclose confidential information. Buffer overflow attacks are said to have arisen because the C programming language supplied the framework, and poor programming practices supplied the vulnerability.
When considering a vendor-specific vulnerability in critical industrial control systems, which of the following techniques supports availability? A. Deploying identical application firewalls at the border B. Incorporating diversity into redundant design C. Enforcing application white lists on the support workstations D. Ensuring the systems' anti-virus definitions are up-to-date
Answer: B Explanation: If you know there is a vulnerability that is specific to one vendor, you can improve availability by implementing multiple systems that include at least one system from a different vendor and so is not affected by the vulnerability.
A new client application developer wants to ensure that the encrypted passwords that are stored in their database are secure from cracking attempts. To implement this, the developer implements a function on the client application that hashes passwords thousands of times prior to being sent to the database. Which of the following did the developer MOST likely implement? A. RIPEMD B. PBKDF2 C. HMAC D. ECDHE
Answer: B Explanation: Password-Based Key Derivation Function 2 (PBKDF2) makes use of a hashing operation, an encryption cipher function, or an HMAC operation) on the input password, which is combined with a salt and is repeated thousands of times.
A company hired Peter, an accountant. The IT administrator will need to create a new account for Peter. The company uses groups for ease of management and administration of user accounts. Peter will need network access to all directories, folders and files within the accounting department. Which of the following configurations will meet the requirements? A. Create a user account and assign the user account to the accounting group. B. Create an account with role-based access control for accounting. C. Create a user account with password reset and notify Peter of the account creation. D. Create two accounts: a user account and an account with full network administration rights.
Answer: B Explanation: Role-based Access Control is basically based on a user's job description. When a user is assigned a specific role in an environment, that user's access to objects is granted based on the required tasks of that role. The IT administrator should, therefore, create an account with role-based access control for accounting for Peter.

Which of the following is true about an email that was signed by User A and sent to User B? A. User A signed with User B's private key and User B verified with their own public key. B. User A signed with their own private key and User B verified with User A's public key. C. User A signed with User B's public key and User B verified with their own private key. D. User A signed with their own public key and User B verified with User A's private key.
Answer: B Explanation: The sender uses his private key, in this case User A's private key, to create a digital signature. The message is, in effect, signed with the private key. The sender then sends the message to the receiver. The receiver (User B) uses the public key attached to the message to validate the digital signature. If the values match, the receiver knows the message is authentic. The receiver uses a key provided by the sender—the public key—to decrypt the message.
Which of the following is a control that allows a mobile application to access and manipulate information which should only be available by another application on the same mobile device (e.g. a music application posting the name of the current song playing on the device on a social media site)? A. Co-hosted application B. Transitive trust C. Mutually exclusive access D. Dual authentication
Answer: B Explanation: Transitive trust is a form of trust that flows from one entity to another so that if A trusts B and B trusts C, A automatically trusts C.
A bank has a fleet of aging payment terminals used by merchants for transactional processing. The terminals currently support single DES but require an upgrade in order to be compliant with security standards. Which of the following is likely to be the simplest upgrade to the aging terminals which will improve in-transit protection of transactional data? A. AES B. 3DES C. RC4 D. WPA2
Answer: B Explanation: 3DES (Triple DES) is based on DES. In cryptography, Triple DES (3DES) is the common name for the Triple Data Encryption Algorithm symmetric-key block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block. The electronic payment industry uses Triple DES and continues to develop and promulgate standards based upon it (e.g. EMV). Microsoft OneNote, Microsoft Outlook 2007, and Microsoft System Center Configuration Manager 2012, use Triple DES to password protect user content and system data.
An administrator is instructed to disable IP-directed broadcasts on all routers in an organization. Which of the following attacks does this prevent? A. Pharming B. Smurf C. Replay D. Xmas
Answer: B Explanation: A smurf attack is a type of network security breach in which a network connected to the Internet is swamped with replies to ICMP echo (PING) requests. A smurf attacker sends PING requests to an Internet broadcast address. These are special addresses that broadcast all received messages to the hosts connected to the subnet. Each broadcast address can support up to 255 hosts, so a single PING request can be multiplied 255 times. The return address of the request itself is spoofed to be the address of the attacker's victim. All the hosts receiving the PING request reply to this victim's address instead of the real sender's address. A single attacker sending hundreds or thousands of these PING messages per second can fill the victim's Internet connection with ping replies, bringing their entire Internet service to its knees. Smurfing falls under the general category of Denial of Service attacks — security attacks that don't try to steal information, but instead attempt to disable a computer or network. By disabling IP-directed broadcasts on all routers, we can prevent the smurf attack by blocking the ping requests to broadcast addresses.
Peter, a security administrator, is informed that people from the HR department should not have access to the accounting department's server, and the accounting department should not have access to the HR department's server. The network is separated by switches. Which of the following is designed to keep the HR department users from accessing the accounting department's server and vice-versa? A. ACLs B. VLANs C. DMZs D. NATS
Answer: B Explanation: A virtual local area network (VLAN) is a hardware-imposed network segmentation created by switches. VLANs are used for traffic management. Communications between ports within the same VLAN occur without hindrance, but communications between VLANs require a routing function.
The datacenter manager is reviewing a problem with a humidity factor that is too low. Which of the following environmental problems may occur? A. EMI emanations B. Static electricity C. Condensation D. Dry-pipe fire suppression
Answer: B Explanation: Humidity control prevents the buildup of static electricity in the environment. If the humidity drops much below 50 percent, electronic components are extremely vulnerable to damage from electrostatic shock.
Physical documents must be incinerated after a set retention period is reached. Which of the following attacks does this action remediate? A. Shoulder Surfing B. Dumpster Diving C. Phishing D. Impersonation
Answer: B Explanation: Incinerating documents (or shredding documents) instead of throwing them into a bin will prevent people being able to read the documents to view sensitive information. Dumpster diving is looking for treasure in someone else's trash. (A dumpster is a large trash container.) In the world of information technology, dumpster diving is a technique used to retrieve information that could be used to carry out an attack on a computer network. Dumpster diving isn't limited to searching through the trash for obvious treasures like access codes or passwords written down on sticky notes. Seemingly innocent information like a phone list, calendar, or organizational chart can be used to assist an attacker using social engineering techniques to gain access to the network. To prevent dumpster divers from learning anything valuable from your trash, experts recommend that your company establish a disposal policy where all paper, including print-outs, is shredded in a cross-cut shredder before being recycled, all storage media is erased, and all staff is educated about the danger of untracked trash.
Verifying the integrity of data submitted to a computer program at or during run-time, with the intent of preventing the malicious exploitation of unintentional effects in the structure of the code, is BEST described as which of the following? A. Output sanitization B. Input validation C. Application hardening D. Fuzzing
Answer: B Explanation: Input validation is a defensive technique intended to mitigate against possible user input attacks, such as buffer overflows and fuzzing. Input validation checks every user input submitted to the application before processing that input. The check could be a length, a character type, a language type, or a domain.
The server administrator has noted that most servers have a lot of free disk space and low memory utilization. Which of the following statements will be correct if the server administrator migrates to a virtual server environment? A. The administrator will need to deploy load balancing and clustering. B. The administrator may spend more on licensing but less on hardware and equipment. C. The administrator will not be able to add a test virtual environment in the data center. D. Servers will encounter latency and lowered throughput issues.
Answer: B Explanation: Migrating to a virtual server environment reduces cost by eliminating the need to purchase, manage, maintain and power physical machines. The fewer physical machines you have, the less money it costs.

Which of the following attacks targets high level executives to gain company information? A. Phishing B. Whaling C. Vishing D. Spoofing
Answer: B Explanation: Whaling is a specific kind of malicious hacking within the more general category of phishing, which involves hunting for data that can be used by the hacker. In general, phishing efforts are focused on collecting personal data about users. In whaling, the targets are high-ranking bankers, executives or others in powerful positions or job titles. Hackers who engage in whaling often describe these efforts as "reeling in a big fish," applying a familiar metaphor to the process of scouring technologies for loopholes and opportunities for data theft. Those who are engaged in whaling may, for example, hack into specific networks where these powerful individuals work or store sensitive data. They may also set up keylogging or other malware on a work station associated with one of these executives. There are many ways that hackers can pursue whaling, leading C-level or top-level executives in business and government to stay vigilant about the possibility of cyber threats.
Which of the following is a security concern regarding users bringing personally-owned devices that they connect to the corporate network? A. Cross-platform compatibility issues between personal devices and server-based applications B. Lack of controls in place to ensure that the devices have the latest system patches and signature files C. Non-corporate devices are more difficult to locate when a user is terminated D. Non-purchased or leased equipment may cause failure during the audits of company-owned assets
Answer: B Explanation: With employees who want to bring their own devices you will have to make them understand why they cannot. You do not want them plugging in a flash drive, let alone a camera, smartphone, tablet computer, or other device, on which company fi les could get intermingled with personal files. Allowing this to happen can create situations where data can leave the building that shouldn't as well as introduce malware to the system. Employees should not sync unauthorized smartphones to their work systems. Some smartphones use multiple wireless spectrums and unwittingly open up the possibility for an attacker in the parking lot to gain access through the phone to the internal network. Thus if you do not have controls in place then your network is definitely at risk.
Which the following flags are used to establish a TCP connection? (Select TWO). A. PSH B. ACK C. SYN D. URG E. FIN
Answer: B,C Explanation: To establish a TCP connection, the three-way (or 3-step) handshake occurs: SYN: The active open is performed by the client sending a SYN to the server. The client sets the segment's sequence number to a random value A. SYN-ACK: In response, the server replies with a SYN-ACK. The acknowledgment number is set to one more than the received sequence number i.e. A+1, and the sequence number that the server chooses for the packet is another random number, B. ACK: Finally, the client sends an ACK back to the server. The sequence number is set to the received acknowledgement value i.e. A+1, and the acknowledgement number is set to one more than the received sequence number i.e. B+1.
A system administrator has noticed network performance issues and wants to gather performance data from the gateway router. Which of the following can be used to perform this action? A. SMTP B. iSCSI C. SNMP D. IPSec
Answer: C
Which statement is TRUE about the operation of a packet sniffer? A. It can only have one interface on a management network. B. They are required for firewall operation and stateful inspection. C. The Ethernet card must be placed in promiscuous mode. D. It must be placed on a single virtual LAN interface.
Answer: C Explanation: A sniffer (packet sniffer) is a tool that intercepts data flowing in a network. If computers are connected to a local area network that is not filtered or switched, the traffic can be broadcast to all computers contained in the same segment. This doesn't generally occur, since computers are generally told to ignore all the comings and goings of traffic from other computers. However, in the case of a sniffer, all traffic is shared when the sniffer software commands the Network Interface Card (NIC) to stop ignoring the traffic. The NIC is put into promiscuous mode, and it reads communications between computers within a particular segment. This allows the sniffer to seize everything that is flowing in the network, which can lead to the unauthorized access of sensitive data. A packet sniffer can take the form of either a hardware or software solution. A sniffer is also known as a packet analyzer.
A database administrator would like to start encrypting database exports stored on the SAN, but the storage administrator warns that this may drastically increase the amount of disk space used by the exports. Which of the following explains the reason for the increase in disk space usage? A. Deduplication is not compatible with encryption B. The exports are being stored on smaller SAS drives C. Encrypted files are much larger than unencrypted files D. The SAN already uses encryption at rest
Answer: C Explanation: Encryption adds overhead to the data which results in and increase in file size. This overhead is attached to each file and could include the encryption/decryption key, data recovery files and data decryption field in file header. As a result, requires increased storage space.
Which of the following is the BEST method for ensuring all files and folders are encrypted on all corporate laptops where the file structures are unknown? A. Folder encryption B. File encryption C. Whole disk encryption D. Steganography
Answer: C Explanation: Full-disk encryption encrypts the data on the hard drive of the device or on a removable drive. This feature ensures that the data on the device or removable drive cannot be accessed in a useable form should it be stolen. Furthermore, full-disk encryption is not dependent on knowledge of the file structure.
Which of the following should be connected to the fire alarm system in order to help prevent the spread of a fire in a server room without data loss to assist in an FM-200 deployment? A. Water base sprinkler system B. Electrical C. HVAC D. Video surveillance
Answer: C Explanation: HVAC refers to heating, ventilation and air-conditioning to allow for a zone-based environmental control measure. The fire-alarm system should ideally also be hooked up to the HVAC so that the HVAC can monitor the changes in heating and ventilation.
A small business needs to incorporate fault tolerance into their infrastructure to increase data availability. Which of the following options would be the BEST solution at a minimal cost? A. Clustering B. Mirrored server C. RAID D. Tape backup
Answer: C Explanation: RAID, or redundant array of independent disks (RAID). RAID allows your existing servers to have more than one hard drive so that if the main hard drive fails, the system keeps functioning. RAID can achieve fault tolerance using software which can be done using the existing hardware and software.
Users have been reporting that their wireless access point is not functioning. They state that it allows slow connections to the internet, but does not provide access to the internal network. The user provides the SSID and the technician logs into the company's access point and finds no issues. Which of the following should the technician do? A. Change the access point from WPA2 to WEP to determine if the encryption is too strong B. Clear all access logs from the AP to provide an up-to-date access list of connected users C. Check the MAC address of the AP to which the users are connecting to determine if it is an imposter D. Reconfigure the access point so that it is blocking all inbound and outbound traffic as a troubleshooting gap
Answer: C Explanation: The users may be connecting to a rogue access point. The rogue access point could be hosting a wireless network that has the same SSID as the corporate wireless network. The only way to tell for sure if the access point the users are connecting to is the correct one is to check the MAC address. Every network card has a unique 48-bit address assigned. A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model. MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware, such as the card's read-only memory or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address (BIA). It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. This can be contrasted to a programmed address, where the host device issues commands to the NIC to use an arbitrary address. A network node may have multiple NICs and each NIC must have a unique MAC address. MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64.
Which of the following would BEST deter an attacker trying to brute force 4-digit PIN numbers to access an account at a bank teller machine? A. Account expiration settings B. Complexity of PIN C. Account lockout settings D. PIN history requirements
Answer: C Explanation: Account lockout settings determine the number of failed login attempts before the account gets locked and how long the account will be locked out for. For example, an account can be configured to lock if three incorrect passwords (or in this case PIN's) are entered. The account can then be configured to automatically unlock after a period of time or stay locked until someone manually unlocks it.
Ann, a security technician, is reviewing the IDS log files. She notices a large number of alerts for multicast packets from the switches on the network. After investigation, she discovers that this is normal activity for her network. Which of the following BEST describes these results? A. True negatives B. True positives C. False positives D. False negatives
Answer: C Explanation: False positives are essentially events that are mistakenly flagged and are not really events to be concerned about.
The security administrator is implementing a malware storage system to archive all malware seen by the company into a central database. The malware must be categorized and stored based on similarities in the code. Which of the following should the security administrator use to identify similar malware? A. TwoFish B. SHA-512 C. Fuzzy hashes D. HMAC
Answer: C Explanation: Hashing is used to ensure that a message has not been altered. It can be useful for positively identifying malware when a suspected file has the same hash value as a known piece of malware. However, modifying a single bit of a malicious file will alter its hash value. To counter this, a continuous stream of hash values is generated for rolling block of code. This can be used to determine the similarity between a suspected file and known pieces of malware.
An organization is recovering data following a datacenter outage and determines that backup copies of files containing personal information were stored in an unsecure location, because the sensitivity was unknown. Which of the following activities should occur to prevent this in the future? A. Business continuity planning B. Quantitative assessment C. Data classification D. Qualitative assessment
Answer: C Explanation: Information classification is done by confidentiality and comprises of three categories, namely: public use, internal use and restricted use. Knowing how to apply these categories and matching it up with the appropriate data handling will address the situation of the data 'unknown sensitivity'
A datacenter requires that staff be able to identify whether or not items have been removed from the facility. Which of the following controls will allow the organization to provide automated notification of item removal? A. CCTV B. Environmental monitoring C. RFID D. EMI shielding
Answer: C Explanation: RFID is radio frequency identification that works with readers that work with 13.56 MHz smart cards and 125 kHz proximity cards and can open turnstiles, gates, and any other physical security safeguards once the signal is read. Fitting out the equipment with RFID will allow you to provide automated notification of item removal in the event of any of the equipped items is taken off the premises.
Which of the following provides a static record of all certificates that are no longer valid? A. Private key B. Recovery agent C. CRLs D. CA
Answer: C Explanation: The CRL (Certificate revocation list) is exactly what its name implies: a list of subscribers paired with digital certificate status. The list enumerates revoked certificates along with the reason(s) for revocation. The dates of certificate issue, and the entities that issued them, are also included. In addition, each list contains a proposed date for the next release. When a potential user attempts to access a server, the server allows or denies access based on the CRL entry for that particular user.
A security administrator is reviewing the company's continuity plan. The plan specifies an RTO of six hours and RPO of two days. Which of the following is the plan describing? A. Systems should be restored within six hours and no later than two days after the incident. B. Systems should be restored within two days and should remain operational for at least six hours. C. Systems should be restored within six hours with a minimum of two days worth of data. D. Systems should be restored within two days with a minimum of six hours worth of data.
Answer: C Explanation: The recovery time objective (RTO) is the maximum amount of time that a process or service is allowed to be down and the consequences still to be considered acceptable. Beyond this time, the break in business continuity is considered to affect the business negatively. The RTO is agreed on during the business impact analysis (BIA) creation. The recovery point objective (RPO) is similar to RTO, but it defines the point at which the system needs to be restored. This could be where the system was two days before it crashed (whip out the old backup tapes) or five minutes before it crashed (requiring complete redundancy). As a general rule, the closer the RPO matches the item of the crash, the more expensive it is to obtain.
Peter, a technician, is tasked with finding a way to test operating system patches for a wide variety of servers before deployment to the production environment while utilizing a limited amount of hardware resources. Which of the following would provide the BEST environment for performing this testing? A. OS hardening B. Application control C. Virtualization D. Sandboxing
Answer: C Explanation: Virtualization is used to host one or more operating systems in the memory of a single host computer and allows multiple operating systems to run simultaneously on the same hardware, reducing costs. Virtualization offers the flexibility of quickly and easily making backups of entire virtual systems, and quickly recovering the virtual system when errors occur. Furthermore, malicious code compromises of virtual systems rarely affect the host system, which allows for safer testing and experimentation.

Which of the following BEST allows the analyst to restrict user access to approved devices? A. Antenna placement B. Power level adjustment C. Disable SSID broadcasting D. MAC filtering
Answer: D Explanation: A MAC filter is a list of authorized wireless client interface MAC addresses that is used by a WAP to block access to all unauthorized devices.
After a company has standardized to a single operating system, not all servers are immune to a well-known OS vulnerability. Which of the following solutions would mitigate this issue? A. Host based firewall B. Initial baseline configurations C. Discretionary access control D. Patch management system
Answer: D Explanation: A patch is an update to a system. Sometimes a patch adds new functionality; in other cases, it corrects a bug in the software. Patch Management can thus be used to fix security problems discovered within the OS thus negating a known OS vulnerability.
Which of the following practices reduces the management burden of access management? A. Password complexity policies B. User account audit C. Log analysis and review D. Group based privileges
Answer: D Explanation: Granting permissions to all members of a group is quicker than individually assigning them to each user. This means an administrator will spend less time on assigning permissions to users who require the same access privileges.
Which of the following is BEST carried out immediately after a security breach is discovered? A. Risk transference B. Access control revalidation C. Change management D. Incident management
Answer: D Explanation: Incident management is the steps followed when security incident occurs.
In which of the following steps of incident response does a team analyze the incident and determine steps to prevent a future occurrence? A. Mitigation B. Identification C. Preparation D. Lessons learned
Answer: D Explanation: Incident response procedures involves in chronological order: Preparation; Incident identification; Escalation and notification; Mitigation steps; Lessons learned; Reporting; Recover/reconstitution procedures; First responder; Incident isolation (Quarantine; Device removal); Data breach; Damage and loss control. Thus lessons are only learned after the mitigation occurred. For only then can you 'step back' and analyze the incident to prevent the same occurrence in future.
LDAP and Kerberos are commonly used for which of the following? A. To perform queries on a directory service B. To store usernames and passwords for Federated Identity C. To sign SSL wildcard certificates for subdomains D. To utilize single sign-on capabilities

Answer: D Explanation: War chalking is the act of making chalk marks on outdoor surfaces (walls, sidewalks, buildings, sign posts, trees) to indicate the existence of an open wireless network connection, usually offering an Internet connection so that others can benefit from the free wireless access. The open connections typically come from the access points of wireless networks located within buildings to serve enterprises. The chalk symbols indicate the type of access point that is available at that specific spot.
A system administrator is setting up a file transfer server. The goal is to encrypt the user authentication and the files the user is sending using only a user ID and a key pair. Which of the following methods would achieve this goal? A. AES B. IPSec C. PGP D. SSH
Answer: D Explanation: With SSH you can use automatically generated public-private key pairs to encrypt a network connection, and then use password authentication to log on. Or you can use a manually generated public-private key pair to perform the authentication, allowing users or programs to log in without having to specify a password.

Which of the following can Peter, a security administrator, implement on his network to capture attack details that are occurring while also protecting his production network? A. Security logs B. Protocol analyzer C. Audit logs D. Honeypot
Answer: D Explanation:A honeypot is a system whose purpose it is to be attacked. An administrator can watch and study the attack to research current attack methodologies. According to the Wepopedia.com, a Honeypot luring a hacker into a system has several main purposes: The administrator can watch the hacker exploit the vulnerabilities of the system, thereby learning where the system has weaknesses that need to be redesigned. The hacker can be caught and stopped while trying to obtain root access to the system. By studying the activities of hackers, designers can better create more secure systems that are potentially invulnerable to future hackers. There are two main types of honeypots: Production - A production honeypot is one used within an organization's environment to help mitigate risk. Research - A research honeypot add value to research in computer security by providing a platform to study the threat.
A system administrator is responding to a legal order to turn over all logs from all company servers. The system administrator records the system time of all servers to ensure that: A. HDD hashes are accurate. B. the NTP server works properly. C. chain of custody is preserved. D. time offset can be calculated.
Answer: D Explanation: It is quite common for workstation times to be off slightly from actual time, and that can happen with servers as well. Since a forensic investigation is usually dependent on a step-by-step account of what has happened, being able to follow events in the correct time sequence is critical. Because of this, it is imperative to record the time offset on each affected machine during the investigation. One method of assisting with this is to add an entry to a log file and note the time that this was done and the time associated with it on the system.

Which of the following could a security administrator implement to mitigate the risk of tailgating for a large organization? A. Train employees on correct data disposal techniques and enforce policies. B. Only allow employees to enter or leave through one door at specified times of the day. C. Only allow employees to go on break one at a time and post security guards 24/7 at each entrance. D. Train employees on risks associated with social engineering attacks and enforce policies.
Answer: D Explanation: Tailgating is the term used for someone being so close to you when you enter a building that they are able to come in right behind you without needing to use a key, a card, or any other security device. Many social engineering intruders needing physical access to a site will use this method of gaining entry. Educate users to beware of this and other social engineering ploys and prevent them from happening.
