Question

A security professional needs to identify a physical security control that will identify and authenticate individuals before allowing them to pass, and restrict passage to only a single person at a time. Which of the following should the professional recommend?

Answer 1

A mantrap

Step-by-step explanation:

A mantrap controls access to a secure area, and only allows one person to pass at a time. The scenario describes the social engineering tactic of tailgating, not the control to prevent it.

Some advanced mantraps include identification and authorization systems, such as biometric systems or smart cards and PINs. However, biometrics and smart cards used for physical security do not restrict passage to one person at a time unless they are combined with a mantrap.
