Explain how a mantrap can assist with physical security when a guard is not practical.

Question

What will be an ideal response?

Answer 1

For areas where an entry guard is not practical, there is another way to prevent tailgating called a mantrap. A mantrap is an entryway with two successive locked doors and a small space between them providing one way entry or exit. After entering the first door, the second door cannot be unlocked until the first door is closed and secured. Access to the second door may be a simple key or may require approval by someone else who watches the trap space on video. Unauthorized persons remain trapped until they are approved for entry, let out the first door, or held for the appropriate authorities.
