CRL Physical Security Assessment & Recommendations Flashcards

What does the term 'layered security' mean in the context of a physical security assessment?

Answer: Using multiple independent security measures so that defeating one layer does not grant full access

Layered security ensures that an attacker must overcome several distinct barriers — lighting, alarms, reinforced frames, and high-security locks — rather than a single obstacle.

A homeowner asks about protecting a door with a double-cylinder deadbolt. What safety concern must the locksmith communicate?

Answer: Double-cylinder deadbolts require a key from both sides and can prevent emergency egress during a fire

Because both sides require a key, occupants can be trapped if a key is not immediately available, creating a life-safety hazard in emergencies.

What is the primary function of a security survey report delivered to a customer after a CRL's assessment?

Answer: To document identified vulnerabilities, prioritized recommendations, and estimated costs so the customer can make informed decisions

A security survey report gives the customer a prioritized action plan with cost context so they can address vulnerabilities based on risk and budget.

When assessing a safe for a small business, which characteristic most directly indicates that it provides burglary resistance rather than just fire protection?

Answer: A UL Residential Security Container (RSC) or TL-rated label indicating it has passed anti-attack testing

Fire safes are designed to protect contents from heat but are not attack-resistant; only safes with UL RSC or TL ratings have been tested against burglary methods.

During a physical security assessment, what does 'natural surveillance' refer to?

Answer: Designing or arranging the environment so that legitimate users can naturally observe and deter criminal activity

Natural surveillance is a Crime Prevention Through Environmental Design (CPTED) principle that uses landscaping, window placement, and layout to maximize visible observation of entry points.

A CRL recommends upgrading to a pick-resistant lock cylinder. Which feature most directly contributes to pick resistance?

Answer: Security pins such as spool or serrated pins that create false sets during picking attempts

Security pins create counter-rotational feedback when manipulated, causing false sets that make single-pin picking significantly more difficult.
