CSC Security System Design & Implementation 3 — Questions and Answers
Question 1: Which physical security standard provides design guidance specifically for protection of critical infrastructure facilities in the US?
- ISO 27001
- ASIS SPC.1 (Correct answer)
- NFPA 72
- UL 2050
Correct answer: ASIS SPC.1
ASIS SPC.1 (Security Management Standard) and related ASIS guidelines provide frameworks for physical security program design including critical infrastructure.
Question 2: A consultant is designing a server room access system. Which authentication factor combination provides the strongest assurance?
- PIN + badge
- Badge only
- Biometric + badge + PIN (Correct answer)
- Biometric only
Correct answer: Biometric + badge + PIN
Three-factor authentication (something you have, something you know, something you are) provides the highest assurance level for high-value assets.
Question 3: What is 'tailgating countermeasure' in access control system design?
- Installing speed bumps at vehicle entrances
- Using mantrap vestibules or door sensors to detect multiple entries per credential (Correct answer)
- Requiring all staff to wear visible ID badges
- Logging all access card transactions
Correct answer: Using mantrap vestibules or door sensors to detect multiple entries per credential
Mantraps and door sensors physically or electronically prevent unauthorized persons from following a valid credential holder through a secure door.
Question 4: When conducting a security system vulnerability assessment, which method involves simulating an attacker's approach to identify weaknesses?
- Gap analysis
- Red team exercise (Correct answer)
- Business impact analysis
- Policy review
Correct answer: Red team exercise
A red team exercise actively simulates adversary tactics to uncover exploitable vulnerabilities that passive assessments may miss.
Question 5: A retail client experiences frequent shoplifting at store exits. Which EAS system type uses hard security tags that trigger an alarm if not removed?
- RFID inventory tracking
- Acousto-magnetic (AM) EAS (Correct answer)
- Video analytics
- Motion-activated lighting
Correct answer: Acousto-magnetic (AM) EAS
Acousto-magnetic EAS systems use hard tags that resonate at a specific frequency when passing through detection pedestals, triggering an alarm.
Question 6: In CCTV system design, what does 'dwell time' refer to?
- Time a camera takes to reboot after power loss
- Duration each camera view is displayed on a multiplexed monitor (Correct answer)
- Delay before recording starts after motion detection
- Time to transmit video over a network
Correct answer: Duration each camera view is displayed on a multiplexed monitor
Dwell time is how long each camera feed is shown on a monitor during sequential switching, affecting how quickly operators notice events.
Question 7: Which document formally specifies the performance requirements a security system must meet before final acceptance by the client?
- Bill of materials
- Basis of design
- Acceptance test procedure (ATP) (Correct answer)
- Change order log
Correct answer: Acceptance test procedure (ATP)
An acceptance test procedure defines measurable criteria against which the installed system is tested to confirm it meets the specified design requirements.
