Option D is incorrect. Requirements to dispose data, specifically sensitive data must be considered when drafting the data policy. Elements of data remanence and relevant issues must be addressed.
Domain : Asset Security
Q9 : When countering data remanence, what technique uses alternating current reduced in amplitude from an initial high?
A. Overwriting
B. Degaussing
C. Encryption
D. Purging
Correct Answer: B
Explanation

A. Temporal Key Integrity Attack
B. WEP (Wired Equivalent Privacy Protocol) attack
C. “Parking Lot” Attack
D. Shared Key Authentication Flaw
Correct Answer: C
Explanation
In a “Parking Lot” attack, the radio signals issued by endpoints are compromised by the hacker to enter the network.
Option A is incorrect. Temporal Key Integrity Attack targets decoding bytes of data, one at a time using multiple replays. The hacker observes the response and can then assess pattern to decode packets
Option B is incorrect. In a WEP (Wired Equivalent Privacy Protocol) attack, the weakness in the underlying RC4 algorithm is exploited to compromise the confidentiality and integrity of traffic passing through wireless LAN
Option C is correct. Endpoints relay circular radio signals which for the most part surpass intended boundaries they are meant to cover (including walls within buildings and floors). The hacker takes advantage of the emissions (e.g., by sitting in a “parking lot”) to compromise the wireless connection and gain access to network
Option D is incorrect. In Shared Key Authentication Flaw, the hacker exploits both the challenge (by the access point), and the cipher response (by the authenticating client), as they are in plain text. The hacker then gains access to the network
