Difficulty: EasySecurity Program Elements and Physical Access Controls

An enterprise organization is establishing physical security measures to protect its central data center network hardware against unauthorized physical intrusion. Which TWO physical access controls should the network security team implement? (Select TWO.)

  1. Biometric scanners installed at server room entrance doorsAnswer
  2. Mantrap vestibules with interlocking doors at facility entry pointsAnswer
  3. C
    TACACS+ authentication protocol deployed for network device CLI access
  4. D
    Extended IPv4 Access Control Lists configured on perimeter router interfaces
  5. E
    Type 1 hypervisor virtual switches isolating virtual server traffic

Answer

Biometric scanners installed at entrance doors and mantrap vestibules with interlocking doors are valid physical access controls.
Physical access controls specifically restrict human physical entry into secure areas containing critical networking hardware. Biometric scanners verify individual physiological traits (such as fingerprint or iris patterns) at door access points, while mantrap vestibules utilize dual interlocking doors to prevent piggybacking or tailgating into data center facilities.

Step-by-Step Solution

1
Distinguish physical security controls from logical or administrative controls.
Physical controls protect tangible assets, facilities, and physical equipment from physical access.
Security controls are categorized by the domain they secure (physical vs technical/logical).
2
Evaluate each choice against physical security functionality.
Biometric locks authenticate physical presence, and mantraps physically regulate physical passage into data centers.
Both measures physically prevent unauthorized humans from entering secure equipment areas.
