What is an example of a physical security best practice at entry points?

• A. Secure doors, anti-passback, mantraps, or controlled access with reader technology.
• B. Public welcome desk and open access.
• C. No signage and default allow.
• D. Unmonitored entry points.

Answer: (A)

Controlling entry with physical access controls. This involves securing doors and using verification methods at the point of entry, such as anti-passback, mantraps, and reader-based access control. Secure doors prevent easy forced entry, anti-passback stops one person from using another’s credential to grant entry to someone else, and mantraps create a controlled choke point that requires proper authorization before anyone can proceed. Reader technology—like badge readers, PINs, or biometrics—confirms identity before access is granted, and logs the entry for accountability. Together, these measures create a layered defense that minimizes the chance of unauthorized entry and tailgating while providing traceability of who enters.

Open access, no signage, default allow, or unmonitored entry points fail to verify identity or monitor activity, which makes them insecure options for entry points.
