Difficulty: MediumPhysical Security Controls

Match each physical security control mechanism on the left with its primary protective function or implementation purpose on the right.

  • Biometric ScannerVerifies identity using unique physical traits such as fingerprints or iris patterns.
  • Cable LockSecures mobile laptops or desktop hardware to stationary fixtures to prevent physical theft.
  • Industrial Cross-Cut ShredderPermanently destroys sensitive paper documents and optical media to prevent dumpster diving.
  • Proximity Card ReaderGrants physical access based on contactless RFID or NFC token detection.

Answer

The correct matches pair Biometric Scanner with verifying identity using unique physical traits, Cable Lock with securing hardware to stationary fixtures, Industrial Cross-Cut Shredder with destroying sensitive paper and optical media, and Proximity Card Reader with granting access via contactless token detection.
Each physical security control serves a specific protective purpose: Biometric scanners use physiological attributes to verify identity, cable locks physically anchor hardware to prevent theft, shredders render physical media unreadable to prevent dumpster diving, and proximity readers validate RFID access tokens.

Step-by-Step Solution

1
Identify the primary function of a Biometric Scanner
Matches with verifying identity via unique physical traits.
Biometrics rely on biological characteristics such as fingerprints or retina scans for authentication.
2
Identify the primary function of a Cable Lock
Matches with securing hardware to stationary fixtures.
Cable locks physically tie down equipment using hardened steel cables connected to security slots.
3
Identify the primary function of an Industrial Cross-Cut Shredder
Matches with destroying paper and media to prevent dumpster diving.
Shredding ensures physical documents and media cannot be reconstructed by attackers.
4
Identify the primary function of a Proximity Card Reader
Matches with granting physical access based on contactless token detection.
Proximity card readers detect RFID/NFC signals emitted from employee access badges.
