Zorluk: OrtaSecurity Program Elements and Physical Access Controls

A network manager is implementing physical security controls at a branch office data room following an incident where an unauthorized visitor entered by closely following an authorized employee through a single access door. Which physical control specifically mitigates tailgating by utilizing a dual-door vestibule where the second door opens only after the first door closes and authentication is validated?

  1. A mantrap system with interlocked access doorsCevap
  2. B
    An automated Access Control List (ACL) applied to the switch port
  3. C
    A TACACS+ centralized server validating remote terminal access
  4. D
    Dynamic Port Security with sticky MAC address learning

Cevap

A mantrap system with interlocked access doors is the physical control specifically designed to prevent tailgating.
A mantrap provides a physical enclosure with two interlocked doors. Entering requires passing through the first door, waiting for it to fully close, and authenticating before the second door unlocks, making tailgating physically impossible.

Adım Adım Çözüm

1
Analyze the physical security vulnerability described in the scenario.
The issue is tailgating (piggybacking), where an unauthorized individual physically follows an authorized individual through a single doorway.
Single door electronic access control systems cannot physically prevent a second person from walking through an open door behind an authorized user.
2
Evaluate the mechanism of a mantrap (physical vestibule).
A mantrap consists of two sets of interlocking doors. The first door opens with credentials, allows one person inside the small enclosed area, closes, and locks before the second door permits entry.
This physical structure ensures only one validated person is admitted at a time, effectively stopping tailgating attempts.
