Which of the following can be configured so that when an alarm is activated, all doors lock and the
suspect or intruder is caught between the doors in the dead-space?

A.
Man trap

B.
Biometric device

C.
Host Intrusion Detection System (HIDS)

D.
Network Intrusion Detection System (NIDS)

Explanation:

A man-trap in modern physical security protocols refers to a small space having two
sets of interlocking doors such that the first set of doors
must close before the second set opens. Identification may be required for each door, and possibly
different measures for each door. For
example, a key may open the first door, but a personal identification number entered on a number
pad opens the second. Other methods of
opening doors include proximity cards or biometric devices such as fingerprint readers or iris
recognition scans. “Man-traps” may be configured
so that when an alarm is activated, all doors lock and trap the suspect between the doors in the
“dead-space” or lock just one door to deny
access to a secure space such as a data center or research lab.
Answer options C, D, and B are incorrect. HIDS, biometric devices, and NIDS cannot be configured to
catch the suspect or intruder between
the doors in the dead-space.
