CPP CPP Physical Security Planning and Design 1 — Questions and Answers
Question 1: Which security design concept recommends organizing security into successive layers so an intruder must defeat multiple barriers?
- Crime Prevention Through Environmental Design (CPTED)
- Defense in Depth (Correct answer)
- Target Hardening
- Security by Obscurity
Correct answer: Defense in Depth
Defense in depth uses multiple overlapping layers of protection so that defeating one layer does not grant full access.
Question 2: What is the primary purpose of a Crime Prevention Through Environmental Design (CPTED) assessment?
- To determine staffing levels for security officers
- To identify how the physical environment can reduce criminal opportunity (Correct answer)
- To evaluate electronic access control systems
- To audit visitor management procedures
Correct 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.
Question 3: A 'standoff distance' in physical security is best described as:
- The minimum distance between security officers on patrol
- The buffer zone between a facility perimeter and a protected structure (Correct answer)
- The range at which surveillance cameras become ineffective
- The gap between fencing panels
Correct 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.
Question 4: Which perimeter barrier is considered a passive anti-ram measure?
- Chain-link fence
- Bollards (Correct answer)
- Electric fence
- Barbed wire
Correct answer: Bollards
Bollards are engineered posts designed to stop or deflect vehicles without active mechanical operation.
Question 5: When conducting a physical security survey, which step comes FIRST?
- Installing upgraded locks
- Defining the facility's assets and their criticality (Correct answer)
- Deploying additional security personnel
- Reviewing incident reports from the past year
Correct 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.
Question 6: Piggybacking (or tailgating) is a threat specifically addressed by which physical control?
- CCTV monitoring
- Mantraps or airlock vestibules (Correct answer)
- Perimeter fencing
- Security lighting
Correct 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.
