ISC2 Certified in Cybersecurity (CC)Access Controls ConceptsMedium
A highly secure research facility requires that all personnel entering sensitive laboratory areas must pass through a mantrap, which is a small room with two interlocking doors. One door must close and lock before the other can open. What type of physical access control is primarily being enforced by this system?
- ADetection
- BDeterrent
- CCorrection
- DDelay
Show answer & explanationAnswer & explanation
Correct answer: D. Delay
A mantrap's primary function is to delay unauthorized access by physically restricting movement and preventing tailgating. While it also deters, its core mechanism is to slow down or halt entry until proper verification, thus providing delay.
Why the other options are wrong
- A. Detection identifies an attack (e.g., alarm systems).
- B. A deterrent discourages an attack (e.g., warning signs).
- C. Correction fixes damage or restores systems after an incident (e.g., backups).
Physical Access Control Types
Categories of physical security mechanisms based on their primary function in safeguarding assets.
- Deterrents discourage attacks.
- Detection identifies attacks in progress.
- Delay slows down attackers.
- Correction remedies damage or restores systems.
Memory trick: Deter, Detect, Delay, Correct: the 4 D's of physical security.
