The correct answer is D: Lock bypass. An under-the-door tool manipulates the interior door handle from outside by sliding through the door gap, circumventing the lock mechanism entirely rather than defeating it directly.
Attacks and exploits
Question
Which of the following types of intrusion techniques is the use of an "under-the-door tool" during a physical security assessment an example of?
Options
- ALockpicking
- BEgress sensor triggering
- CLock bumping
- DLock bypass
Explanation
An under-the-door tool manipulates the interior door handle from outside by sliding through the door gap, circumventing the lock mechanism entirely rather than defeating it directly.
Common mistakes.
- A. Lockpicking involves inserting tension wrenches and picks into the lock cylinder to manipulate internal pins or wafers to replicate the correct key, which is a direct attack on the locking mechanism itself.
- B. Egress sensor triggering exploits motion-activated or pressure-sensitive electronic door-release mechanisms near exits, not a physical door handle or lock cylinder.
- C. Lock bumping uses a specially cut bump key inserted into a pin tumbler lock that is struck to momentarily displace the driver pins above the shear line, which is a direct mechanical attack on the lock cylinder.
