Certified Network Defender (CND) — Question 36

Justine has been tasked by her supervisor to ensure that the company's physical security is on the same level as their logical security measures. She installs video cameras at all entrances and exits and installs badge access points for all doors. The last item she wants to install is a method to prevent unauthorized people piggybacking employees. What should she install to prevent piggybacking?

Answer options

• A. Justine needs to install a biometrics station at each entrance.
• B. She should install a mantrap.
• C. She should install a Thompson Trapdoor.
• D. Justine will need to install a revolving security door.

Correct answer: B

Explanation

The correct answer is B, as a mantrap is specifically designed to prevent piggybacking by requiring one person to exit before another can enter. Options A and D do not provide the same level of security against unauthorized entry, and option C is not a recognized security measure for this purpose.
