Which term describes a system that uses a sensor to detect a security breach?

• A. Intrusion detection system
• B. Likelihood
• C. Incident
• D. Hazard

Answer: (A)

An intrusion detection system is a system that uses sensors to detect a security breach. It monitors protected areas with devices like door/window contacts, motion sensors, and cameras, and triggers an alarm or alert when unauthorized access is detected so security personnel can respond promptly. The other terms refer to different ideas: likelihood is the probability of an event occurring, not a detection system; an incident is the actual event that occurs after a breach; a hazard is a potential source of harm, not a sensor-based monitoring system.
