Physical Security Flashcards

A security manager wants to prevent tailgating at a high-security data center entrance. Which control is MOST effective?

Answer: Mantrap (airlock) with one-person-at-a-time enforcement

A mantrap physically prevents more than one person from passing through at a time, directly eliminating tailgating opportunities.

Which type of motion detector uses radar-like signals to detect movement through walls and objects?

Answer: Microwave detector

Microwave detectors emit microwave pulses and measure reflections, allowing detection through non-metallic barriers.

A data center is located in a flood-prone area. Which site design choice BEST mitigates flood risk?

Answer: Elevate critical equipment above the base flood elevation

Elevating critical equipment above the base flood elevation prevents water from reaching hardware even if flooding occurs.

What is the PRIMARY purpose of a Faraday cage in a secure facility?

Answer: Block electromagnetic signals from entering or leaving

A Faraday cage is a conductive enclosure that attenuates electromagnetic fields, preventing signal eavesdropping and interference.

Which access control approach grants physical access based on something the user is?

Answer: Biometric scanner

Biometric scanners use physiological or behavioral characteristics (something you are) to authenticate individuals.

A company stores backup tapes off-site. Which physical security control is MOST important for the transport process?

Answer: Encrypting the tapes before transport

Encrypting tapes ensures that even if they are lost or stolen during transport, the data cannot be read.

What does CPTED (Crime Prevention Through Environmental Design) primarily aim to achieve?

Answer: Deter crime by designing the physical environment to reduce opportunity

CPTED uses natural surveillance, access control, and territorial reinforcement in facility design to reduce criminal opportunity.
