CompTIA Security Plus Mock Test Q352

Which of the following should be considered to mitigate data theft when using CAT5 wiring?

A. CCTV
B. Environmental monitoring
C. Multimode fiber
D. EMI shielding


Correct Answer: D
Section: Compliance and Operational Security

Explanation:
EMI Shielding refers to the process of preventing electronic emissions from your computer systems from being used to gather intelligence and preventing outside electronic emissions from disrupting your information-processing abilities. Thus all wiring should be shielded to mitigate data theft.

Incorrect Answers:
A: CCTV is used to record everything it sees, thus creating evidence in case of theft. Though data theft can also occur over a network and a camera will only record the area where it is set up. Shielding is a more important data theft mitigation measure.
B: Environmental monitoring is carried out by means of a HVAC system and furthermore shielding the wiring is part of environmental monitoring.
C: Multimode fiber is not used to mitigate data theft.
