Question

Difficulty: MediumPhysical Security Controls

A network security technician is hardening the physical security measures for a newly established satellite datacenter. The facility manager specifies two primary security goals: first, preventing unauthorized individuals from gaining entry by closely following authorized staff through outer access points, and second, ensuring that server hardware cannot be removed from equipment enclosures if room perimeter security is compromised. Which of the following physical security controls should the technician implement to meet these specific requirements? (Select TWO.)

  1. An access control vestibule equipped with anti-passback authentication controlsAnswer
  2. Locking rack enclosures securely bolted to the facility floorAnswer
  3. C
    Privacy filters installed on all monitoring workstation displays
  4. D
    Faraday cages enclosed around wireless access points
  5. E
    Vehicle bollards installed along the facility parking perimeter

Answer

The technician should implement an access control vestibule equipped with anti-passback controls to prevent tailgating, along with locking rack enclosures bolted to the floor to prevent physical hardware theft.
An access control vestibule (mantrap) using anti-passback authentication prevents unauthorized users from tailgating authorized staff through entryways. Locking rack enclosures bolted to the building floor provide targeted hardware security, preventing server units from being physically disconnected and carried away.

Step-by-Step Solution

1
Analyze the physical security threats described in the scenario
Two distinct physical risks are identified: unauthorized entry via tailgating/piggybacking and physical theft of server hardware.
Choosing effective physical controls requires mapping specific mechanisms directly to the identified physical security threat vectors.
2
Select the physical control for tailgating prevention
An access control vestibule (mantrap) with anti-passback authentication ensures that only one credentialed person passes through at a time.
Interlocking doors prevent second individuals from following authorized personnel without validating their own credentials.
3
Select the physical control for equipment theft prevention
Locking rack enclosures anchored directly to the floor secure individual host systems and hardware units.
Securing rack doors and anchoring the frame ensures servers cannot be removed or stolen even if room-level access control fails.
