SSP Security Technology & Systems 2 — Questions and Answers
Question 1: Which biometric technology measures the unique pattern of blood vessels in the human eye?
- Retinal scan (Correct answer)
- Iris recognition
- Facial recognition
- Vascular mapping
Correct answer: Retinal scan
Retinal scanning captures the unique pattern of blood vessels at the back of the eye, distinct from iris recognition which reads the colored ring around the pupil.
Question 2: What is the primary purpose of a Faraday cage in a security context?
- Block electromagnetic signals from entering or leaving an area (Correct answer)
- Prevent physical intrusion into a server room
- Shield against laser eavesdropping
- Reduce radio frequency interference in equipment
Correct answer: Block electromagnetic signals from entering or leaving an area
A Faraday cage blocks electromagnetic signals, preventing wireless eavesdropping and protecting sensitive electronics from external RF interference.
Question 3: In access control terminology, what does 'tailgating' refer to?
- An unauthorized person following an authorized person through a secure door (Correct answer)
- Monitoring employee movements via CCTV
- Piggybacking a signal on a legitimate radio frequency
- Forcing a door open with a tool
Correct answer: An unauthorized person following an authorized person through a secure door
Tailgating occurs when an unauthorized person closely follows an authorized individual through a controlled entry point without presenting credentials.
Question 4: What type of lock uses a series of rotating discs aligned by a key to allow the bolt to move?
- Wafer tumbler lock
- Pin tumbler lock
- Disc detainer lock (Correct answer)
- Lever tumbler lock
Correct answer: Disc detainer lock
Disc detainer locks use rotating discs that must all align to a specific position when the correct key is inserted before the bolt can move.
Question 5: Which standard governs the testing and rating of bullet-resistant glazing materials in the US?
- ASTM F1233
- UL 752 (Correct answer)
- NIJ 0108.01
- ANSI Z97.1
Correct answer: UL 752
UL 752 is the Underwriters Laboratories standard for bullet-resisting equipment, rating glazing into eight levels based on the ammunition type they resist.
Question 6: What is the function of a mantrap (also called a sally port) in physical security?
- Trap intruders between two electronically controlled doors (Correct answer)
- Monitor perimeter motion with dual sensors
- Encrypt radio transmissions between guards
- Log all keycard access attempts
Correct answer: Trap intruders between two electronically controlled doors
A mantrap uses two interlocking doors so only one can open at a time, trapping anyone who cannot provide valid credentials before entering the secured area.
Question 7: Which intrusion detection sensor is best suited to detecting movement based on changes in ambient heat signatures?
- Microwave sensor
- Passive infrared (PIR) sensor (Correct answer)
- Ultrasonic sensor
- Glass-break sensor
Correct answer: Passive infrared (PIR) sensor
Passive infrared sensors detect movement by sensing changes in infrared (heat) energy in their field of view, making them effective at identifying human presence.
