FILL BLANK
Fill in the blank with the appropriate term. _______________is the process, policies, and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster.

  1. Disaster recovery

Answer(s): A

Explanation:

Disaster recovery is the process, policies, and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster. Disaster recovery planning is a subset of a larger process known as business continuity planning and should include planning for resumption of applications, data, hardware, communications (such as networking) and other IT infrastructure. A business continuity plan (BCP) includes planning for non-IT related aspects such as key personnel, facilities, crisis communication and reputation protection, and should refer to the disaster recovery plan (DRP) for IT related infrastructure recovery / continuity.



You are advising a school district on disaster recovery plans. In case a disaster affects the main IT centers for the district they will need to be able to work from an alternate location. However, budget is an issue. Which of the following is most appropriate for this client?

  1. Warm site
  2. Cold site
  3. Hot site
  4. Off site

Answer(s): B

Explanation:

A cold site provides an office space, and in some cases basic equipment. However, you will need to restore your data to that equipment in order to use it. This is a much less expensive solution than the hot site.
Answer option C is incorrect. A hot site has equipment installed, configured and ready to use. This may make disaster recovery much faster, but will also be more expensive. And a school district can afford to be down for several hours before resuming IT operations, so the less expensive option is more appropriate.
Answer option A is incorrect. A warm site is between a hot and cold site. It has some equipment ready and connectivity ready. However, it is still significantly more expensive than a cold site, and not necessary for this scenario.
Answer option D is incorrect. Off site is not any type of backup site terminology.



Which of the following techniques uses a modem in order to automatically scan a list of telephone numbers?

  1. War driving
  2. War dialing
  3. Warchalking
  4. Warkitting

Answer(s): B

Explanation:

War dialing is a technique of using a modem to automatically scan a list of telephone numbers, usually dialing every number in a local area code to search for computers, BBS systems, and fax machines. Hackers use the resulting lists for various purposes, hobbyists for exploration, and crackers (hackers that specialize in computer security) for password guessing.
Answer option C is incorrect. Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi wireless network. Having found a Wi-Fi node, the warchalker draws a special symbol on a nearby object, such as a wall, the pavement, or a lamp post. The name warchalking is derived from the cracker terms war dialing and war driving.
Answer option A is incorrect. War driving, also called access point mapping, is the act of locating and possibly exploiting connections to wireless local area networks while driving around a city or elsewhere. To do war driving, one needs a vehicle, a computer (which can be a laptop), a wireless Ethernet card set to work in promiscuous mode, and some kind of an antenna which can be mounted on top of or positioned inside the car. Because a wireless LAN may have a range that extends beyond an office building, an outside user may be able to intrude into the network, obtain a free Internet connection, and possibly gain access to company records and other resources.
Answer option D is incorrect. Warkitting is a combination of wardriving and rootkitting. In a warkitting attack, a hacker replaces the firmware of an attacked router. This allows them to control all traffic for the victim, and could even permit them to disable SSL by replacing HTML content as it is being downloaded. Warkitting was identified by Tsow, Jakobsson, Yang, and Wetzel in 2006. Their discovery indicated that 10% of the wireless routers were susceptible to WAPjacking (malicious configuring of the firmware settings, but making no modification on the firmware itself) and 4.4% of wireless routers were vulnerable to WAPkitting (subverting the router firmware). Their analysis showed that the volume of credential theft possible through Warkitting exceeded the estimates of credential theft due to phishing.



FILL BLANK
Fill in the blank with the appropriate file system. Alternate Data Streams (ADS) is a feature of
The________________ file system, allowing more than one data stream to be associated with a filename.

  1. NTFS

Answer(s): A

Explanation:

Alternate Data Streams (ADS) is a feature of the NTFS file system that allows more than one data stream to be associated with a filename, using the filename format "filename:streamname". Alternate streams are not listed in Windows Explorer, and their size is not included in the file size. ADS provides the hacker a place to hide root kits or hacker tools, which can be executed without being detected by the system administrator. Alternate Data Streams are strictly a feature of the NTFS file system. Alternate Data Streams may be used as a method of hiding executables or proprietary content.
