Which of the following is most likely to prevent tampering with server hardware that houses data?

Question

Options

• ABiometric locks
• BStrong password policy
• CNetwork firewall
• DSurveillance cameras

• A
  71% (29)
• B
  5% (2)
• C
  7% (3)
• D
  17% (7)

Explanation

Biometric locks directly prevent unauthorized physical access to server hardware by requiring a unique biological identifier (fingerprint, retina scan, etc.) to enter the room or rack - making tampering physically impossible without authenticated presence.

• B (Strong password policy) protects logical/software access to systems, not physical hardware - someone can still walk up and pull a drive.
• C (Network firewall) operates at the network layer and does nothing to stop someone standing in front of the server.
• D (Surveillance cameras) may deter or detect tampering after the fact, but they don't prevent it - hardware can still be touched.

Memory tip: Think "prevent = physical barrier." Biometrics are the only choice that creates an actual gate between an attacker and the hardware. Cameras watch, firewalls filter traffic, passwords protect logins - only locks block.
