Assessment and Evaluation Flashcards

A security director wants to determine whether a new CCTV system reduced parking lot incidents. Which evaluation approach is most valid?

Answer: Compare incident rates before and after installation while controlling for other variables

Before-and-after comparison controlling for confounding factors gives the most defensible measure of effectiveness.

What is 'Return on Investment' (ROI) in a security context primarily used to demonstrate?

Answer: The financial value of security programs relative to their cost

Security ROI shows management that program costs are justified by avoided losses or gained value.

Which factor is MOST important when evaluating the vulnerability of an asset?

Answer: The weaknesses that could be exploited by a threat

Vulnerability is defined by exploitable weaknesses in protection that a threat could use.

In a security survey, why should the surveyor review past incident reports?

Answer: To identify loss patterns and trends that indicate vulnerabilities

Historical incident data reveals patterns that help focus the assessment on real problem areas.

Which statement best describes the 'probability of interruption' in a physical protection system evaluation?

Answer: The likelihood that responders arrive in time to stop the adversary before the task is complete

Probability of interruption reflects timely detection plus response arriving before the adversary succeeds.

What does the 'critical detection point' represent in adversary path analysis?

Answer: The last point on the path where detection still allows enough response time to interrupt

Detection after the critical detection point leaves insufficient time for response to interrupt the attack.

Which of the following is the best example of a key performance indicator (KPI) for a guard force?

Answer: Average alarm response time compared with the target standard

Response time against a defined standard is a measurable indicator of guard performance.
