Question 1

What is the definition of 'threat' in physical security terminology?

Accepted Answer

Any person, event, or condition with potential to cause harm

Answer

A threat is any person (adversary), natural event, or technical condition that has the potential to cause harm to assets, people, or operations.

Question 2

Which type of glass is most recommended for high-security applications identified during a physical security assessment?

Accepted Answer

Laminated security glass

Answer

Laminated security glass contains an interlayer that holds fragments together when broken, providing significant forced-entry delay compared to other glass types.

Question 3

During a security assessment for a jewelry store, a locksmith should identify the UL rating most relevant to safes and vaults protecting high-value merchandise. Which rating addresses burglary resistance?

Accepted Answer

UL 687

Answer

UL 687 is the Underwriters Laboratories standard for burglary-resistant safes, specifying tool-resistant attack time ratings relevant to high-value retail environments.

Question 4

A client wants to understand 'security in depth.' Which statement best describes this principle?

Accepted Answer

Using multiple overlapping security layers so that defeating one does not compromise the whole system

Answer

Security in depth (layered security) ensures that multiple independent barriers, detection systems, and procedures must all be defeated for an attack to succeed.

Question 5

When assessing a facility for after-hours security, which combination of factors most increases the risk of an undetected intrusion?

Accepted Answer

No alarm system, no exterior lighting, and a hollow-core door on a weak frame

Answer

The combination of no alarm, no lighting (eliminating natural surveillance at night), and a structurally weak door/frame creates maximum vulnerability with minimal detection or delay.
