What is the purpose of 'crime prevention through environmental design' (CPTED)?
Answer: Using security cameras in all areas
CPTED uses environmental design principles to reduce opportunities for criminal activity, including natural surveillance, natural access control, territorial reinforcement, and maintenance.
What is a 'perimeter intrusion detection system' (PIDS) used for?
Answer: Detecting unauthorized intrusions along a facility's perimeter using sensors, cameras, and alarms
A PIDS detects unauthorized access attempts along a facility's perimeter through various sensor technologies, triggering alerts that allow security personnel to respond.
What is the purpose of 'mantrap' or 'airlock' entry systems in physical security?
Answer: To create a buffer zone that prevents tailgating by requiring each person to be authenticated before the inner door opens
A mantrap or airlock entry system prevents tailgating by requiring that one door fully close and authenticate before the next door opens, ensuring each person entering is individually verified.
What is 'biometric authentication' and what advantage does it provide over traditional access cards?
Answer: Authentication using unique physical or behavioral characteristics that cannot easily be stolen, lost, or shared
Biometric authentication uses unique physical traits (fingerprints, iris patterns, facial features) that are much harder to steal, duplicate, or share than access cards, providing stronger authentication.
What is a 'security lighting' requirement and how does it contribute to physical security?
Answer: Illumination that deters unauthorized activity by reducing concealment opportunities and enabling surveillance cameras to capture clear images
Security lighting deters unauthorized access by eliminating dark areas where intruders could conceal themselves and improving visibility for security patrols and surveillance cameras.
What is a 'vehicle barrier system' and when is it used?
Answer: Physical barriers (bollards, walls, vehicle traps) designed to prevent vehicle-borne attacks against facilities
Vehicle barrier systems prevent vehicle-borne threats (such as car bombs or ramming attacks) from reaching critical facilities by using passive or active physical barriers.
