Physical Security Assessment & Vulnerability Analysis Flashcards

What is the primary purpose of a physical security vulnerability assessment performed by a CFL?

Answer: To identify weaknesses in locking systems that could be exploited

A physical security vulnerability assessment identifies weaknesses in locking systems and access controls that could be exploited by an attacker.

Which rating system is commonly used in the US to classify lock resistance to attack?

Answer: ANSI/BHMA grading system (Grades 1, 2, and 3)

The ANSI/BHMA grading system classifies door hardware into Grades 1, 2, and 3 based on durability and security resistance.

What does 'forced entry resistance' refer to in physical security assessments?

Answer: A lock's ability to withstand drilling, prying, and kick-in attacks

Forced entry resistance measures how well a locking system withstands physical attacks such as drilling, prying, or impact that bypass the key mechanism.

A CFL finds a Grade 3 deadbolt on an exterior door during a security survey. What is the forensic significance?

Answer: Grade 3 is the lowest ANSI grade, offering minimal resistance to forced entry

ANSI Grade 3 is the lowest security classification, meaning the lock provides minimal resistance to forced entry compared to Grade 1 hardware.

Which factor is most critical when assessing a strike plate during a vulnerability assessment?

Answer: Length of mounting screws reaching into the door frame stud

Strike plate security depends on screw length penetrating the structural stud, as short screws allow kick-in attacks even when a high-grade deadbolt is installed.

When documenting vulnerabilities, what should a CFL note about a lock cylinder's projection beyond the door face?

Answer: Excessive projection increases the risk of a cylinder pull attack by providing leverage

Excessive cylinder projection beyond the door face provides leverage for cylinder pull attacks and must be documented as a critical vulnerability.
