What is the purpose of a 'standoff distance' in physical security planning?
Answer: To establish a minimum distance between a potential explosive device and a protected structure
Standoff distance is a planned buffer that reduces blast effects on a structure by keeping potential explosive threats farther away.
In a physical security survey, 'layers of protection' refers to:
Answer: A defense-in-depth strategy using multiple barriers and controls
Defense-in-depth layers multiple physical and procedural controls so that defeating one layer does not compromise the entire security system.
Which of the following is the BEST indicator of a well-maintained physical security program during a survey?
Answer: Current, tested procedures with documented maintenance records
Documented, tested procedures and maintenance records demonstrate that the security program is actively managed and operationally effective.
A mantrap (access control vestibule) is designed primarily to:
Answer: Prevent tailgating and control access one person at a time
A mantrap uses interlocked doors to ensure only one person passes through at a time, directly preventing tailgating into secured areas.
During a survey, a surveyor should assess 'target hardening' measures. Target hardening BEST describes:
Answer: Physical modifications that make a target more difficult or less attractive to attack
Target hardening involves physical modifications—locks, barriers, reinforcement—that increase the difficulty and risk for a potential attacker.
Which intrusion detection sensor is MOST appropriate for detecting motion in a large open warehouse space?
Answer: Passive infrared (PIR) motion detector
Passive infrared detectors sense body heat movement across wide open areas, making them ideal for large interior spaces like warehouses.
When evaluating a facility's key control program during a survey, which finding represents the MOST serious vulnerability?
Answer: Keys are labeled with room numbers for convenience
Labeling keys with room numbers enables a lost or stolen key to be used immediately against the targeted lock, creating a critical vulnerability.
