SFPC Physical Security Measures 2 — Questions and Answers
Question 1: What is the purpose of 'crime prevention through environmental design' (CPTED)?
- Using security cameras in all areas (Correct answer)
- Designing or modifying the physical environment to reduce the opportunities for crime and unauthorized access
- Installing alarm systems in all locations
- Placing security guards at every entrance
Correct 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.
Crime Prevention Through Environmental Design (CPTED) is a multi-disciplinary approach to deterring criminal behavior through environmental design. The four main principles are natural surveillance (designing spaces so that people can observe what is happening), natural access control (using landscape and design to guide movement), territorial reinforcement (creating a sense of ownership to deter unauthorized entry), and maintenance (keeping facilities in good condition to signal care and attention).
Question 2: What is a 'perimeter intrusion detection system' (PIDS) used for?
- Monitoring employee attendance
- Detecting unauthorized intrusions along a facility's perimeter using sensors, cameras, and alarms (Correct answer)
- Managing vehicle access credentials
- Providing lighting for nighttime operations
Correct 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.
A Perimeter Intrusion Detection System (PIDS) is an electronic security system designed to detect unauthorized penetration of a defined perimeter. PIDS components include various sensor technologies (microwave, seismic, fiber optic, video analytics) positioned along the perimeter that trigger alerts when disturbed. The alerts allow security personnel to assess and respond to potential intrusions before they reach the facility interior.
Question 3: What is the purpose of 'mantrap' or 'airlock' entry systems in physical security?
- To trap insects and pests
- To create a buffer zone that prevents tailgating by requiring each person to be authenticated before the inner door opens (Correct answer)
- To improve air circulation in secure facilities
- To store hazardous materials safely
Correct 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.
A mantrap (also called an airlock or sally port) is a physical security control consisting of a small, enclosed space with interlocking doors that requires individual authentication. The first door must be completely closed and the entering person authenticated before the second door will open. This prevents tailgating and piggybacking, ensuring each person entering a secure area is individually authorized.
Question 4: What is 'biometric authentication' and what advantage does it provide over traditional access cards?
- A method using multiple keys to open a lock
- Authentication using unique physical or behavioral characteristics that cannot easily be stolen, lost, or shared (Correct answer)
- A type of electronic keypad
- A backup authentication method
Correct 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.
Biometric authentication uses unique biological characteristics such as fingerprints, iris patterns, facial geometry, or voice recognition to verify identity. Unlike access cards (something you have) or PINs (something you know), biometrics verify something you are. This provides stronger authentication because biometric characteristics cannot be stolen, lost, or easily shared, though they are not without their own vulnerabilities (spoofing, accuracy issues).
Question 5: What is a 'security lighting' requirement and how does it contribute to physical security?
- Lighting used only during emergencies
- Illumination that deters unauthorized activity by reducing concealment opportunities and enabling surveillance cameras to capture clear images (Correct answer)
- Decorative lighting for facility aesthetics
- Lighting that automatically activates during fire alarms
Correct 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.
Security lighting is a fundamental physical security measure that serves multiple purposes: it deters unauthorized activity by removing the concealment that darkness provides, enables security personnel and cameras to identify individuals and activities, and creates a psychological deterrent. Effective security lighting covers perimeters, parking areas, entry points, and other critical areas without creating blinding glare or excessive shadows.
Question 6: What is a 'vehicle barrier system' and when is it used?
- Speed bumps for employee parking lots
- Physical barriers (bollards, walls, vehicle traps) designed to prevent vehicle-borne attacks against facilities (Correct answer)
- Tire deflation devices for unauthorized vehicles
- Vehicle registration checkpoints
Correct 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.
Vehicle barrier systems are physical security measures designed to prevent unauthorized or hostile vehicles from approaching critical facilities. They include passive barriers (fixed bollards, concrete barriers, planters) and active barriers (rising bollards, vehicle traps, beam barriers) that can be deployed or lowered as needed. Vehicle barriers are particularly important at facilities with assessed vehicle-borne threat risks.
