Zorluk: OrtaPhysical Security Controls

An organization needs to secure the physical entrance of a sensitive server room to prevent tailgating, where an unauthorized person follows an authorized employee through a door. Which of the following physical security controls is designed specifically to enforce single-person entry and eliminate this risk?

  1. An access control vestibuleCevap
  2. B
    A proximity smart card reader
  3. C
    A privacy filter
  4. D
    Perimeter bollards

Cevap

An access control vestibule is specifically designed with interlocking doors to allow only one person to pass through at a time, effectively preventing tailgating.
An access control vestibule (also known as a mantrap) features two interlocking doors that require the outer door to be completely closed and secured before the inner door opens. This physically restricts movement so only one individual can pass through at a time, eliminating tailgating.

Adım Adım Çözüm

1
Identify the physical security threat in the scenario.
The primary risk identified is tailgating (piggybacking), where an unauthorized individual enters behind an authorized person through a single access point.
Understanding the specific physical security threat dictates which control mechanism is required.
2
Evaluate the mechanism of an access control vestibule.
An access control vestibule consists of two interlocking doors. The first door must close and lock before the second door unlocks, isolating the person entering.
This physical design enforces single-person entry and prevents unauthorized entry behind an authorized user.
3
Compare against non-optimal or improper controls.
Proximity readers, privacy filters, and bollards address authentication, visual eavesdropping, and vehicle impact respectively, but none physically block tailgating.
Selecting the correct physical barrier requires matching the specific protective function to the threat.
