The correct answer to this question is A. Man trap.
A man trap is a physical security mechanism designed to restrict access to a secure area. It is a small room or enclosure that has two or more doors or gates, which can be locked or unlocked in a coordinated manner. The doors cannot be opened simultaneously, meaning that only one door can be open at any given time. The man trap can be designed in a way that when an alarm is activated, all doors lock and the suspect or intruder is caught between the doors in the dead-space. This is known as an anti-passback mechanism, which ensures that no one can enter or exit the secure area without proper authorization.
A biometric device is a security mechanism that uses physical or behavioral characteristics to authenticate the identity of an individual. It can be used for access control, but it does not have the ability to lock doors in the event of an alarm.
A Host Intrusion Detection System (HIDS) is a security mechanism that monitors and analyzes the activity of a single host, such as a computer or server. It does not have the ability to lock doors or physically prevent intruders from entering a secure area.
A Network Intrusion Detection System (NIDS) is a security mechanism that monitors network traffic to detect and prevent unauthorized access or malicious activity. It also does not have the ability to lock doors or physically prevent intruders from entering a secure area.
In summary, a man trap is the only security mechanism listed that can be configured to lock doors and physically prevent an intruder from entering or leaving a secure area in the event of an alarm.
