Applied Methods and Techniques Flashcards

A common security specification for chain-link perimeter fencing is which configuration?

Answer: 7-foot fabric plus a top guard of barbed wire for about 8 feet total

Security fencing typically uses 7 feet of fabric topped with a barbed-wire outrigger for roughly 8 feet total.

What is the main purpose of a clear zone on both sides of a perimeter fence?

Answer: To give unobstructed observation and deny concealment or climbing aids

Clear zones remove cover and climbing aids and keep sightlines open for detection and assessment.

In security lighting, what does a footcandle measure?

Answer: Illuminance equal to one lumen per square foot

A footcandle is the illuminance on a surface receiving one lumen per square foot.

Why is lighting uniformity ratio important for security and video coverage?

Answer: High contrast between bright and dark spots creates shadows where intruders can hide and challenges cameras

Poor uniformity creates dark pockets and glare that undermine observation and camera performance.

Which statement correctly contrasts quantitative and qualitative risk assessment?

Answer: Quantitative uses numerical values such as probabilities and dollar losses; qualitative uses relative ratings such as high/medium/low

Quantitative methods assign numeric values, while qualitative methods use descriptive scales.

For a PPS to successfully interrupt an adversary, which condition must hold after the first detection?

Answer: Remaining adversary delay time must exceed the response force time

Responders must arrive before the adversary finishes the remaining tasks on the path.

How does a performance-based assessment differ from a feature-based (compliance) assessment?

Answer: It measures how well the system actually performs against a defined threat, often with testing and modeling

Performance-based approaches evaluate effectiveness quantitatively against threats rather than simply checking for features.
