CompTIA Security+ (SY0-501) — Question 570

A company needs to fix some audit findings related to its physical security. A key finding was that multiple people could physically enter a location at the same time. Which of the following is the BEST control to address this audit finding?

Answer options

• A. Faraday cage
• B. Mantrap
• C. Biometrics
• D. Proximity cards

Correct answer: B

Explanation

The correct answer is B, Mantrap, as it is specifically designed to control access by ensuring that only one person can enter or exit at a time, thereby addressing the issue of multiple individuals entering simultaneously. The other options, while they may enhance security, do not directly prevent multiple entries at once; for example, a Faraday cage blocks electromagnetic fields, biometrics authenticate individuals, and proximity cards provide access but do not control the number of people entering.
