CSS Security Technology & Systems Flashcards

What does the term 'false negative' mean in the context of an intrusion detection system?

Answer: The system fails to detect a real intrusion, producing no alarm

A false negative occurs when an IDS fails to detect an actual security breach, which is more dangerous than a false positive.

A guard tour system is used in security operations primarily to:

Answer: Verify that officers are completing patrols at the correct checkpoints and times

Guard tour systems record officer checkpoint scans to verify patrol routes are completed on schedule and document officer activity.

Which of the following is the best reason for a security supervisor to conduct regular testing of alarm systems?

Answer: Regular testing ensures the system functions correctly and officers know how to respond when an alarm activates

Regular alarm testing verifies system functionality and ensures officers are trained and ready to respond appropriately to alarms.

A video management system (VMS) is used by security supervisors to:

Answer: Centrally manage and review live and recorded CCTV footage from multiple cameras

A VMS provides centralized control, live monitoring, and recorded video review for all cameras connected to the security network.

When a security alarm is triggered, the first action a CSS supervisor should take is:

Answer: Treat it as a real event, dispatch a response, and investigate to confirm or rule out an actual threat

Every alarm should be treated as real until verified otherwise; immediate dispatch and investigation are the correct supervisory response.

Which technology uses unique physical characteristics such as fingerprints or retinal scans to verify identity?

Answer: Biometric access control

Biometric access control authenticates individuals based on unique physical traits, providing a high level of identity assurance.
