Explanation
A man trap (or mantrap) is a physical security control specifically designed to prevent tailgating - the practice of an unauthorized person following an authorized person through a secured door. It consists of a small enclosed vestibule with two interlocking doors: the first door must fully close and authenticate the individual before the second door will open, ensuring only one person passes at a time. Pick-resistant locks, electronic key systems, and electronic combination locks all help control access but do not physically prevent a second person from slipping through behind an authorized user.
