CFL Security System Analysis 2

Question 1

When analyzing an alarm system for forensic evidence, which component is most likely to retain tamper data logs?

Accepted Answer

Control panel memory/event log

Answer

The control panel event log stores timestamped records of zone activations, bypasses, and tamper events.

Question 2

A security camera system shows video gaps during an alleged burglary. Which forensic analysis should be performed FIRST?

Accepted Answer

Examine DVR/NVR power and event logs for intentional disabling

Answer

Power cycling logs and DVR event records can reveal whether the system was manually disabled or lost power during the incident.

Question 3

In a layered security system, which layer is considered the 'detection' layer?

Accepted Answer

Interior motion sensors and glass break detectors

Answer

Interior sensors such as motion detectors and glass break detectors form the detection layer, alerting to intrusion after perimeter is breached.

Question 4

A forensic locksmith finds a door contact sensor displaced from its frame. What conclusion is MOST forensically sound?

Accepted Answer

The sensor may have been deliberately moved to create a gap and bypass the zone

Answer

Displaced sensors can defeat zone monitoring; deliberate repositioning is a known bypass method and must be documented as potential evidence.

Question 5

What does a 'zone fault' condition indicate in a commercial intrusion detection system?

Accepted Answer

A wiring issue or open circuit in a specific zone

Answer

A zone fault typically indicates a broken wire, disconnected sensor, or short circuit within that specific detection zone.
