SFPC - Security Fundamentals Professional Physical Security Measures Questions and Answers 1 — Questions and Answers
Question 1: A security manager is implementing Crime Prevention Through Environmental Design (CPTED) principles for a new corporate campus. Which of the following measures BEST exemplifies the principle of 'Natural Surveillance'?
- Installing a high-perimeter fence with a single, guarded entry point.
- Using thorny bushes below ground-floor windows and ensuring building entrances are well-lit and visible from the street. (Correct answer)
- Issuing key cards to all employees to restrict access to specific buildings.
- Posting signs that clearly define the property line and designate private areas.
Correct answer: Using thorny bushes below ground-floor windows and ensuring building entrances are well-lit and visible from the street.
Natural Surveillance, a core principle of CPTED, focuses on designing the environment to maximize visibility and the perception that people can be seen. Placing thorny bushes makes it difficult for potential intruders to hide near windows, and ensuring entrances are well-lit and visible from public areas increases the chances that illicit activities will be observed by employees, visitors, or passersby.
Question 2: A facility uses a physical access control system (PACS) where employees present a key fob to a reader to unlock a door. Which components are essential for this system to function?
- Biometric scanner, server, and a security guard.
- Motion detector, alarm, and a keypad.
- Credential, reader, and a control panel. (Correct answer)
- Surveillance camera, turnstile, and a visitor log.
Correct answer: Credential, reader, and a control panel.
A basic electronic physical access control system requires a credential (the key fob), a reader to interpret the credential's data, and a control panel that makes the access decision and signals the lock to open. The server stores the access rules and logs, and the control panel communicates with it, but the core interaction at the access point involves the credential, reader, and controller.
Question 3: Which of the following physical security measures primarily serves as a deterrent by making it difficult for an intruder to see into a protected area from the outside?
- Standby lighting
- Bollards
- Glare projection lighting (Correct answer)
- Perimeter fencing
Correct answer: Glare projection lighting
Glare projection is a lighting technique where lights are directed outward from a protected area. This creates a wall of light that makes it difficult for outsiders to see inside the perimeter, serving as a strong deterrent. Standby lighting is activated by sensors, bollards are physical barriers against vehicles, and fencing is a physical barrier but does not inherently obstruct vision in this manner.
Question 4: A data center is located in an area prone to power outages. To ensure its physical security systems, including access controls and surveillance, remain operational at all times, which of the following is the MOST critical supporting measure?
- A loud, audible alarm system.
- An uninterruptible power supply (UPS) and backup generator. (Correct answer)
- Motion-activated security cameras.
- A contract with a local security guard service.
Correct answer: An uninterruptible power supply (UPS) and backup generator.
Physical security systems like access controls and surveillance cameras rely on electricity. During a power outage, these systems will fail. An uninterruptible power supply (UPS) provides immediate, short-term power, while a backup generator can sustain power for an extended period. This ensures continuous operation of critical security measures. The other options are valuable but do not address the fundamental issue of power loss.
Question 5: Which type of physical intrusion detection system (PIDS) sensor is specifically designed to detect an unauthorized entry through a door or window?
- A passive infrared (PIR) sensor
- A glass-break detector
- A magnetic contact switch (Correct answer)
- A microwave sensor
Correct answer: A magnetic contact switch
A magnetic contact switch consists of two parts: a magnet attached to a door or window and a switch on the frame. When the door or window is opened, the magnetic field is broken, which triggers the alarm. This makes it a direct detector of an opening, whereas other sensors detect motion (PIR, microwave) or the sound of breaking glass.
Question 6: Bollards are a type of physical security barrier primarily designed to protect against which of the following threats?
- Unauthorized pedestrian access
- Vehicular impact and ram-raiding (Correct answer)
- Covert surveillance attempts
- Climbing over perimeter fences
Correct answer: Vehicular impact and ram-raiding
Bollards are robust vertical posts designed to act as protective barriers against vehicle intrusions, whether accidental or intentional (ram-raiding). They are strategically placed to protect buildings, pedestrian areas, and other sensitive locations from vehicular impact. They are not primarily designed to stop pedestrians, surveillance, or climbing.
