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.
