Q1. Which of the following tools will allow a technician to detect security-related TCP connection anomalies?
A. Logical token
B. Performance monitor
C. Public key infrastructure
D. Trusted platform module
Answer: B
Explanation:
Performance Monitor in a Windows system can monitor many different ‘counters’. For TCP network connections, you can monitor specific TCP related counters including the following: Connection Failures Connections Active Connections Established Connections Passive Connections Reset Segments Received/sec Segments Retransmitted/sec Segments Sent/sec Total Segments/sec
By monitoring the counters listed above, you will be able to detect security-related TCP connection anomalies.
Q2. Which of the following would Matt, a security administrator, use to encrypt transmissions from an internal database to an internal server, keeping in mind that the encryption process must add as little latency to the process as possible?
A. ECC
B. RSA
C. SHA
D. 3DES
Answer: D
Explanation:
3DES would be less secure compared to ECC, but 3DES would require less computational power. Triple-DES (3DES) is a technological upgrade of DES. 3DES is still used, even though AES is the preferred choice for government applications. 3DES is considerably harder to break than many other systems, and it’s more secure than DES. It increases the key length to 168 bits (using three 56-bit DES keys).
Q3. Which of the following should Matt, a security administrator, include when encrypting smartphones? (Select TWO).
A. Steganography images
B. Internal memory
C. Master boot records
D. Removable memory cards
E. Public keys
Answer: B,D
Explanation:
All useable data on the device should be encrypted. This data can be located on the hard drive, or removable drives, such as USB devices and memory cards, and on internal memory.
Q4. A security administrator has been tasked with setting up a new internal wireless network that must use end to end TLS. Which of the following may be used to meet this objective?
A. WPA
B. HTTPS
C. WEP
D. WPA 2
Answer: D
Explanation:
Wi-Fi Protected Access 2 (WPA2) was intended to provide security that’s equivalent to that on a wired network, and it implements elements of the 802.11i standard. In April 2010, the Wi-Fi Alliance announced the inclusion of additional Extensible Authentication Protocol (EAP) types to its certification programs for WPA- and WPA2- Enterprise certification programs. EAP-TLS is included in this certification program. Note: Although WPA mandates the use of TKIP, WPA2 requires Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP). CCMP uses 128-bit AES encryption with a 48-bit initialization vector. With the larger initialization vector, it increases the difficulty in cracking and minimizes the risk of a replay attack.
Q5. Which of the following devices will help prevent a laptop from being removed from a certain location?
A. Device encryption
B. Cable locks
C. GPS tracking
D. Remote data wipes
Answer: B
Explanation:
Cable locks are theft deterrent devices that can be used to tether a device to a fixed point keep smaller devices from being easy to steal.
Q6. Sara, a security engineer, is testing encryption ciphers for performance. Which of the following ciphers offers strong encryption with the FASTEST speed?
A. 3DES
B. Blowfish
C. Serpent
D. AES256
Answer: B
Explanation:
Blowfish is an encryption system invented by a team led by Bruce Schneier that performs a 64-bit block cipher at very fast speeds. Blowfish is a fast, except when changing keys. It is a symmetric block cipher that can use variable-length keys (from 32 bits to 448 bits).
Q7. A security team has established a security awareness program. Which of the following would BEST prove the success of the program?
A. Policies
B. Procedures
C. Metrics
D. Standards
Answer: C
Explanation:
All types of training should be followed up- be tested to see if it worked and how much was learned in the training process. You must follow up and gather training metrics to validate compliance and security posture. By training metrics, we mean some quantifiable method for determining the efficacy of training.
Q8. Prior to leaving for an extended vacation, Joe uses his mobile phone to take a picture of his family in the house living room. Joe posts the picture on a popular social media site together with the message: "Heading to our two weeks vacation to Italy." Upon returning home, Joe discovers that the house was burglarized. Which of the following is the MOST likely reason the house was burglarized if nobody knew Joe’s home address?
A. Joe has enabled the device access control feature on his mobile phone.
B. Joe’s home address can be easily found using the TRACEROUTE command.
C. The picture uploaded to the social media site was geo-tagged by the mobile phone.
D. The message posted on the social media site informs everyone the house will be empty.
Answer: C
Explanation:
Geo-tagging is the process of embedding the GPS coordinates in image files and images taken using a smartphone or a digital camera. The geotagged information accompanying the image allows anyone to discover the precise location where the image was taken.
Q9. An IT security technician needs to establish host based security for company workstations. Which of the following will BEST meet this requirement?
A. Implement IIS hardening by restricting service accounts.
B. Implement database hardening by applying vendor guidelines.
C. Implement perimeter firewall rules to restrict access.
D. Implement OS hardening by applying GPOs.
Answer: D
Explanation: Hardening is the process of securing a system by reducing its surface of vulnerability. Reducing the surface of vulnerability typically includes removing or disabling unnecessary functions and features, removing or disabling unnecessary user accounts, disabling unnecessary protocols and ports, and disabling unnecessary services. This can be implemented using the native security features of an operating system, such as Group Policy Objects (GPOs).
Q10. In order for Sara, a client, to logon to her desktop computer, she must provide her username, password, and a four digit PIN. Which of the following authentication methods is Sara using?
A. Three factor
B. Single factor
C. Two factor
D. Four factor
Answer: B
Explanation:
Single-factor authentication is when only one authentication factor is used. In this case, Something you know is being used as an authentication factor. Username, password, and PIN form part of Something you know.
Q11. A forensic analyst is reviewing electronic evidence after a robbery. Security cameras installed at the site were facing the wrong direction to capture the incident. The analyst ensures the cameras are turned to face the proper direction. Which of the following types of controls is being used?
A. Detective
B. Deterrent
C. Corrective
D. Preventive
Answer: C
Explanation:
A corrective control would be any corrective action taken to correct any existing control that were faulty or wrongly installed – as in this case the cameras were already there, it just had to be adjusted to perform its function as intended.
Q12. One of the most basic ways to protect the confidentiality of data on a laptop in the event the device is physically stolen is to implement which of the following?
A. File level encryption with alphanumeric passwords
B. Biometric authentication and cloud storage
C. Whole disk encryption with two-factor authentication
D. BIOS passwords and two-factor authentication
Answer: C
Explanation: Whole-disk encryption only provides reasonable protection when the system is fully powered off. to make the most of the defensive strength of whole-disk encryption, a long, complex passphrase should be used to unlock the system on bootup. Combining whole-disk encryption with two factor authentication would further increase protection.
Q13. The librarian wants to secure the public Internet kiosk PCs at the back of the library. Which of the following would be the MOST appropriate? (Select TWO).
A. Device encryption
B. Antivirus
C. Privacy screen
D. Cable locks
E. Remote wipe
Answer: B,D
Explanation:
B: Antivirus software is used to protect systems against viruses, which are a form of malicious code designed to spread from one system to another, consuming network resources. Public systems are particularly prone to viruses.
D: Cable locks are theft deterrent devices that can be used to tether a device to a fixed point keep devices from being easy to steal.
