CPP Physical Security Planning and Design Flashcards

Which security design concept recommends organizing security into successive layers so an intruder must defeat multiple barriers?

Answer: Defense in Depth

Defense in depth uses multiple overlapping layers of protection so that defeating one layer does not grant full access.

What is the primary purpose of a Crime Prevention Through Environmental Design (CPTED) assessment?

Answer: To identify how the physical environment can reduce criminal opportunity

CPTED focuses on modifying the built environment—lighting, landscaping, and sight lines—to deter criminal activity.

A 'standoff distance' in physical security is best described as:

Answer: The buffer zone between a facility perimeter and a protected structure

Standoff distance is the measured space between a potential vehicle-borne threat and a building to reduce blast impact.

Which perimeter barrier is considered a passive anti-ram measure?

Answer: Bollards

Bollards are engineered posts designed to stop or deflect vehicles without active mechanical operation.

When conducting a physical security survey, which step comes FIRST?

Answer: Defining the facility's assets and their criticality

Identifying and prioritizing assets establishes what must be protected before any countermeasure can be properly selected.

Piggybacking (or tailgating) is a threat specifically addressed by which physical control?

Answer: Mantraps or airlock vestibules

A mantrap allows only one person to pass through a controlled entry at a time, preventing an unauthorized person from following an authorized one.
