Difficulty: EasyPhysical Security Controls

Match each physical security control to its primary protective function.

  • Biometric readerAuthenticates identity using unique physical characteristics
  • Privacy filterPrevents visual eavesdropping and shoulder surfing on displays
  • Cable lockSecures portable hardware to immovable physical fixtures
  • Faraday bagBlocks external wireless and electromagnetic signals

Answer

Biometric reader pairs with authenticating identity using unique physical characteristics; Privacy filter pairs with preventing visual eavesdropping; Cable lock pairs with securing portable hardware to immovable fixtures; Faraday bag pairs with blocking external wireless signals.
Biometric readers authenticate physical traits, privacy filters block side-angle screen visibility, cable locks physically anchor equipment to prevent theft, and Faraday bags block electromagnetic signal transmission.

Step-by-Step Solution

1
Analyze each security control's operational role.
Biometrics relate to physical authentication, privacy filters address screen visibility, cable locks prevent physical device theft, and Faraday bags block radio signals.
Matching each physical control directly to its operational target ensures standard physical security principles are applied.
