Question

Difficulty: MediumPhysical Security Controls

An IT security team is implementing physical defense controls across an enterprise facility. Match each physical security control mechanism on the left to its corresponding protective security objective on the right.

  • USB Port LocksPrevents unauthorized physical insertion of removable media into exposed workstation ports.
  • Faraday ShieldingBlocks external radio frequency signals from reaching or emanating from sensitive devices.
  • Biometric Scanner with Liveness DetectionMitigates authentication spoofing attempts that utilize static photos or mold replicas.
  • Tamper-Evident Asset TagDeters unauthorized chassis opening, component swapping, and enables inventory tracking.

Answer

USB Port Locks matches with preventing unauthorized physical insertion of removable media; Faraday Shielding matches with blocking radio frequency signals; Biometric Scanner with Liveness Detection matches with mitigating authentication spoofing attempts; Tamper-Evident Asset Tag matches with deterring unauthorized chassis opening and component swapping.
Each physical security control serves a specific technical function: USB port locks physically obstruct ports against unauthorized media insertion; Faraday shielding blocks RF wireless signals; liveness detection verifies real-time physical presence to defeat biometric spoofing; and tamper-evident asset tags reveal physical tampering or component theft.

Step-by-Step Solution

1
Analyze the primary purpose of USB Port Locks
Identified physical obstruction of unused system ports to block flash drive insertion.
Physical port locks restrict unauthorized peripheral connections.
2
Analyze the primary purpose of Faraday Shielding
Identified RF containment and signal blockage.
Faraday enclosures absorb or reflect external electromagnetic waves.
3
Analyze the role of Liveness Detection in biometric scanning
Identified detection of real-time physiological indicators (e.g., pulse, eye movement).
Liveness verification prevents spoofing with static photos or artificial replicas.
4
Analyze Tamper-Evident Asset Tags
Identified permanent damage patterns when disturbed.
Tamper indicators signal unauthorized physical access or component replacement.
