CompTIA Security Plus Mock Test Q702

Which of the following would MOST likely involve GPS?

A. War driving
B. Protocol analyzer
C. Replay attack
D. WPS attack


Correct Answer: A
Section: Threats and Vulnerabilities

Explanation:
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, you need 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. A GPS (Global Positioning System) system can be used to accurately map your location while detecting the wireless networks.

Incorrect Answers:
B: A Protocol Analyzer is a hardware device or more commonly a software program used to capture network data communications sent between devices on a network. Capturing
packets sent from a computer system is known as packet sniffing. GPS is not used for packet sniffing.
C: A replay attack (also known as playback attack) is a form of network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed. This is carried out
either by the originator or by an adversary who intercepts the data and retransmits it, possibly as part of a masquerade attack by IP packet substitution (such as stream cipher attack).
GPS is not used for replay attacks.
D: Wi-Fi Protected Setup (WPS) is a communications protocol designed to help facilitate the setup of wireless networks in homes and small offices. A WPS attack is an attempt to gain
unauthorized access to the wireless network. GPS is not used for WPS attacks.
