Which design principle ensures that a security breach in one zone does not automatically compromise adjacent zones?
Answer: Segmentation
Segmentation isolates zones so that a compromise in one segment does not propagate to others.
A client wants a door access control system that logs every entry attempt. Which component is MOST critical for forensic investigation?
Answer: Audit trail with timestamps
An audit trail with timestamps provides the evidentiary record needed for post-incident forensic analysis.
When designing a CCTV system for a parking garage, what is the primary factor determining camera spacing?
Answer: Field of view and resolution requirements
Camera spacing must be determined by field of view and resolution to ensure adequate coverage without blind spots.
Which intrusion detection topology places sensors on every possible path an intruder might take to reach a protected asset?
Answer: Perimeter detection
Perimeter detection creates a boundary layer that triggers on the earliest possible intrusion attempt before the interior is reached.
A security consultant recommends a dual-technology motion detector in a room with large windows. What threat does this address?
Answer: False alarms from sunlight or HVAC air movement
Dual-technology detectors require two sensing methods to trigger simultaneously, dramatically reducing false alarms caused by environmental factors.
In electronic access control, what is the purpose of a 'request-to-exit' (REX) sensor?
Answer: To allow free egress without triggering an alarm
A REX sensor detects outbound movement and shunts the door alarm circuit so a legitimate exit does not generate an alert.
A hospital security design must allow rapid evacuation during a fire while maintaining access control. Which feature addresses this conflict?
Answer: Fail-safe (fail-open) locking on egress doors tied to fire alarm
Fail-safe locks release upon fire alarm activation, satisfying life-safety egress requirements while normally maintaining access control.
