Which term describes a secured entry with two doors requiring authentication before access to secure areas?

• A. Mantrap
• B. MitM
• C. Masquerading
• D. Modem

Answer: (A)

A mantrap is a physical access control feature that uses two interlocked doors. You must authenticate at the first door before the second door will open to grant access to the secure area. This setup prevents tailgating or piggybacking and ensures that entry is tightly controlled and monitored, since only one person can pass through at a time and credentials are checked before access is allowed.

The other terms refer to different concepts: a man-in-the-middle is a network attack where an attacker intercepts communications between two parties; masquerading is pretending to be someone else within a system; and a modem is a device for modulating and demodulating signals for network communication.
