CSS CSS Security Technology & Systems 2 — Questions and Answers
Question 1: What does the term 'false negative' mean in the context of an intrusion detection system?
- The system triggers an alarm when no threat exists
- The system fails to detect a real intrusion, producing no alarm (Correct answer)
- The system correctly identifies a threat
- The system shuts down unexpectedly
Correct 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.
Question 2: A guard tour system is used in security operations primarily to:
- Schedule officer vacations
- Verify that officers are completing patrols at the correct checkpoints and times (Correct answer)
- Track the location of security vehicles only
- Manage payroll processing
Correct 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.
Question 3: Which of the following is the best reason for a security supervisor to conduct regular testing of alarm systems?
- Testing is required only after a system failure
- Regular testing ensures the system functions correctly and officers know how to respond when an alarm activates (Correct answer)
- Testing is unnecessary if the system was recently installed
- Alarms only need testing during annual audits
Correct 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.
Question 4: A video management system (VMS) is used by security supervisors to:
- Edit and alter security footage for reporting purposes
- Centrally manage and review live and recorded CCTV footage from multiple cameras (Correct answer)
- Replace physical security officers entirely
- Broadcast company announcements to employees
Correct 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.
Question 5: When a security alarm is triggered, the first action a CSS supervisor should take is:
- Assume it is a false alarm and reset the system
- Treat it as a real event, dispatch a response, and investigate to confirm or rule out an actual threat (Correct answer)
- Call the alarm company and wait for their instructions before responding
- Notify the media immediately
Correct 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.
Question 6: Which technology uses unique physical characteristics such as fingerprints or retinal scans to verify identity?
- Proximity card readers
- Biometric access control (Correct answer)
- RFID fencing systems
- Mechanical lock and key
Correct answer: Biometric access control
Biometric access control authenticates individuals based on unique physical traits, providing a high level of identity assurance.
