Physical Security Design & Implementation Flashcards

Which lighting standard is most commonly referenced for exterior security lighting in US facilities?

Answer: IESNA RP-33

IESNA RP-33 provides recommended practice for security lighting of exterior environments in the United States.

In Crime Prevention Through Environmental Design (CPTED), 'natural surveillance' is best achieved by:

Answer: Designing spaces so legitimate users can observe activity

Natural surveillance relies on physical design—windows, open sightlines, and activity generators—so occupants passively monitor an area.

A standoff distance in blast-resistant design refers to:

Answer: The minimum distance between a potential vehicle bomb and a protected structure

Standoff distance is the space between a vehicle-borne IED threat and the building, reducing blast overpressure impact.

Which door hardware standard classifies electrified locks and strikes used in access control integration?

Answer: ANSI/BHMA A156.25

ANSI/BHMA A156.25 covers electrified door hardware including electric strikes and electromagnetic locks used with access control systems.

The primary purpose of a mantrap (airlock) in a high-security facility is to:

Answer: Prevent tailgating by allowing only one person through at a time

A mantrap forces individual occupant verification before granting access, eliminating tailgating/piggybacking into secure spaces.

When designing a perimeter using the '3-3-3 rule' for vehicle barriers, the numbers represent:

Answer: Vehicle weight (tons), speed (mph), and penetration depth (feet)

The 3-3-3 rule references a 3-ton vehicle at 30 mph with no more than 3 feet of intrusion, forming the basis for K4 barrier ratings.

In a layered physical security model, which layer is responsible for protecting individual assets such as servers or filing cabinets?

Answer: Asset layer

The asset or object layer is the innermost protection ring, using safes, locked cabinets, and device-level controls to secure specific items.
