Difficulty: MediumSecurity Program Elements and Physical Access Controls

An organization is upgrading the physical security posture of its main data center facility. The security team must implement controls that explicitly address tailgating mitigation at perimeter entryways and provide environmental surveillance inside server rooms. Which two physical security controls directly fulfill these specific requirements? (Select two.)

  1. Mantrap portal with interlocking doorsAnswer
  2. Closed-circuit television (CCTV) camerasAnswer
  3. C
    Tacacs+ centralized authentication server
  4. D
    Port Security with sticky MAC address learning
  5. E
    Role-Based Access Control (RBAC) lists

Answer

The correct controls are implementing a mantrap portal with interlocking doors to prevent tailgating and installing closed-circuit television (CCTV) cameras for interior server room surveillance.
A mantrap portal uses two interlocking doors to ensure only one authenticated person enters at a time, directly preventing tailgating. Closed-circuit television (CCTV) cameras provide visual monitoring and surveillance inside secure areas such as server rooms.

Step-by-Step Solution

1
Analyze the scenario requirements
Identified two specific physical security needs: mitigating tailgating at perimeter entryways and establishing environmental/visual surveillance inside server rooms.
Physical access control measures fall into categories like physical barriers, biometrics, surveillance, and access logging.
2
Evaluate perimeter control options for tailgating mitigation
The mantrap portal enforces single-person entry via interlocked doors, directly preventing tailgating.
Mantraps force a verification cycle before allowing entry through the secondary interior door.
3
Evaluate surveillance options for server room interiors
CCTV camera deployment provides active visual monitoring and recorded audit trails of physical movement.
Surveillance systems ensure accountability and visibility inside critical data center rooms.
