Question No: 204 – (Topic 2)

A security administrator needs to image a large hard drive for forensic analysis. Which of the following will allow for faster imaging to a second hard drive?

  1. cp /dev/sda /dev/sdb bs=8k

  2. tail -f /dev/sda gt; /dev/sdb bs=8k

  3. dd in=/dev/sda out=/dev/sdb bs=4k

  4. locate /dev/sda /dev/sdb bs=4k

Answer: C Explanation:

dd is a command-line utility for Unix and Unix-like operating systems whose primary purpose is to convert and copy files. dd can duplicate data across files, devices, partitions and volumes

On Unix, device drivers for hardware (such as hard disks) and special device files (such as

/dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files, provided that function is implemented in their respective driver. As a result, dd can be used for tasks such as backing up the boot sector of a hard drive, and obtaining a fixed amount of random data. The dd program can also perform conversions on the data as it is copied, including byte order swapping and conversion to and from the ASCII and EBCDIC text encodings.

An attempt to copy the entire disk using cp may omit the final block if it is of an unexpected length; whereas dd may succeed. The source and destination disks should have the same size.

Question No: 205 – (Topic 2)

In the initial stages of an incident response, Matt, the security administrator, was provided the hard drives in question from the incident manager. Which of the following incident response procedures would he need to perform in order to begin the analysis? (Select TWO).

  1. Take hashes

  2. Begin the chain of custody paperwork

  3. Take screen shots

  4. Capture the system image

  5. Decompile suspicious files

Answer: A,D Explanation:

A: Take Hashes. NIST (the National Institute of Standards and Technology) maintains a National Software Reference Library (NSRL). One of the purposes of the NSRL is to collect “known, traceable software applications” through their hash values and store them in a Reference Data Set (RDS). The RDS can then be used by law enforcement, government agencies, and businesses to determine which fi les are important as evidence in criminal investigations.

D: A system image is a snapshot of what exists. Capturing an image of the operating system in its exploited state can be helpful in revisiting the issue after the fact to learn more about it.

Question No: 206 – (Topic 2)

Which of the following is the BEST concept to maintain required but non-critical server availability?

  1. SaaS site

  2. Cold site

  3. Hot site

  4. Warm site

Answer: D Explanation:

Warm sites provide computer systems and compatible media capabilities. If a warm site is used, administrators and other staff will need to install and configure systems to resume operations. For most organizations, a warm site could be a remote office, a leased facility, or another organization with which yours has a reciprocal agreement. Another term for a warm site/reciprocal site is active/active model.

Question No: 207 – (Topic 2)

Joe, the system administrator, has been asked to calculate the Annual Loss Expectancy (ALE) for a $5,000 server, which often crashes. In the past year, the server has crashed 10 times, requiring a system reboot to recover with only 10% loss of data or function. Which of the following is the ALE of this server?

A. $500

B. $5,000 C. $25,000 D. $50,000

Answer: B Explanation:

SLE 脳 ARO = ALE, where SLE is equal to asset value (AV) times exposure factor (EF); and ARO is the annualized rate of occurrence.

(5000 x 10) x 0.1 = 5000
