Difficulty: MediumSecurity Program Elements and Physical Access Controls

A network administrator is auditing the infrastructure security measures for a newly constructed enterprise data center facility. Which two measures represent physical access controls specifically designed to protect physical hardware and prevent unauthorized physical entry? (Select two.)

  1. Implementation of a dual-door mantrap portal that requires sequential credential authentication for entryAnswer
  2. Installation of biometric door scanners paired with electronic smart card badge readers at facility entrywaysAnswer
  3. C
    Enforcement of annual user security awareness training covering phishing and social engineering tactics
  4. D
    Configuration of extended IPv4 Access Control Lists on perimeter edge routers to filter unauthorized traffic
  5. E
    Deployment of TACACS+ authentication servers to manage remote SSH command access for administrators

Answer

The two correct physical access controls are the implementation of a dual-door mantrap portal with sequential credential authentication, and the installation of biometric door scanners paired with electronic smart card badge readers.
Physical access controls are mechanisms designed to guard physical spaces, facilities, and network infrastructure hardware. A dual-door mantrap portal prevents unauthorized tailgating by locking one door until the person inside is verified before opening the inner door. Biometric scanners and electronic badge readers serve as physical access controls that validate identity before permitting entry to server rooms.

Step-by-Step Solution

1
Categorize each security measure in the options as physical, administrative, or technical.
Mantrap portals and biometric badge readers are physical controls; security training is an administrative program control; ACLs and TACACS+ are technical controls.
The question specifically asks for physical access controls that restrict physical access to facilities.
2
Select the controls that physically prevent unauthorized individuals from gaining physical access to network equipment.
Dual-door mantraps and biometric badge readers directly enforce physical perimeter security.
Physical controls rely on physical barriers, hardware devices, and mechanical or electronic entry locks to guard facilities.

Key Concept

Physical access controls involve physical barriers, biometric locks, badge readers, and mantraps to protect facilities and network hardware from unauthorized physical access.
