Physical Security Assessment & Planning Flashcards

In the protection system concept of detect, delay, and respond, what is the purpose of delay?

Answer: To slow the adversary long enough for the response force to arrive

Delay elements buy time between detection and adversary task completion so responders can interrupt.

Delay is most effective when it is placed where in relation to detection?

Answer: After the point of detection

Delay that occurs after detection is useful because the response is already underway; undetected delay adds little value.

A qualitative risk assessment typically differs from a quantitative one in that it:

Answer: Uses relative ratings such as high, medium, and low

Qualitative assessments rely on descriptive or ordinal scales rather than precise numerical values.

Annualized Loss Expectancy (ALE) is calculated as:

Answer: Single Loss Expectancy x Annualized Rate of Occurrence

ALE = SLE x ARO, giving expected yearly loss from a given threat.

Which group should a security manager involve EARLIEST when planning security for a new facility construction project?

Answer: The architect and design team during the conceptual design phase

Integrating security during early design is far less costly than retrofitting after construction.

In CPTED, the use of fencing, signage, and pavement treatments to define private space is called:

Answer: Territorial reinforcement

Territorial reinforcement uses physical cues to express ownership and distinguish public from private space.

A vulnerability assessment finds that response time is 8 minutes but total adversary task time after detection is 4 minutes. What does this indicate?

Answer: The response force will likely arrive too late to interrupt the adversary

For interruption, delay after detection must exceed response force time.
