According to CPTED (Crime Prevention Through Environmental Design) principles, 'natural surveillance' is BEST achieved by:
Answer: Designing spaces that maximize visibility so occupants can observe their surroundings
Natural surveillance is a CPTED strategy that uses architectural and landscape design—such as open sightlines, windows facing parking areas, and low shrubbery—to enable people to see and be seen naturally.
A security consultant is assessing a facility's vehicle perimeter protection. Which barrier is rated to stop a 15,000-lb vehicle traveling at 50 mph?
Answer: K12-rated crash-rated bollards
The DOS/ASTM crash-rating scale designates K12 as barriers capable of stopping a 15,000-lb vehicle at 50 mph; this rating is required for high-security government facilities.
What is the RECOMMENDED minimum standoff distance between a high-value facility and the public street, per U.S. security guidelines for blast-resistant design?
Answer: 82 feet
100 meters (approximately 328 ft) is ideal, but 25 meters (82 feet) is often cited as the minimum practical standoff distance to significantly reduce blast overpressure damage to a facility.
A security consultant reviews a facility that has a fence line running parallel to a busy sidewalk with only 2 feet of separation. This configuration PRIMARILY creates risk because:
Answer: Pedestrians can reach over or cut the fence without being seen from the facility
Insufficient setback between a perimeter fence and a public area allows an adversary to attack, cut, or scale the fence with minimal exposure time, significantly degrading the perimeter's effectiveness.
Which perimeter intrusion detection system (PIDS) technology is MOST susceptible to false alarms caused by animals and wind-blown debris?
Answer: Active infrared beam sensors
Active infrared (IR) beam sensors are highly susceptible to false alarms from insects, birds, dust, and small animals crossing the beam path, especially in outdoor environments.
A CSC is developing a physical security plan for an executive office building. The OUTERMOST layer of a concentric ring protection model should address:
Answer: Controlling vehicle and pedestrian access at the property boundary
In a concentric ring model, the outermost layer (perimeter) addresses vehicle and pedestrian control at the property boundary, with successive inner rings providing progressively tighter controls.
Security lighting that automatically activates when motion is detected but remains off otherwise is categorized as:
Answer: Standby lighting
Standby lighting (also called responsive or triggered lighting) remains off until activated by an alarm or motion sensor, preserving darkness as a security tool while providing illumination on demand.
