A security consultant is assessing a facility that stores high-value assets. Which perimeter security layer provides the FIRST line of defense?

The outer perimeter fencing forms the first layer of defense in a defense-in-depth perimeter security model.
Which access control model grants permissions based on the sensitivity label of a resource and the clearance level of the subject?

Mandatory Access Control (MAC) uses sensitivity labels and clearance levels to enforce access decisions, commonly used in government and military systems.
A 'mantrap' (airlock) entry system is PRIMARILY designed to prevent which security threat?

A mantrap prevents tailgating by ensuring only one person passes through a controlled entry at a time before the second door opens.
When designing perimeter lighting for a secure facility, what is the recommended minimum foot-candle level for boundaries according to general security standards?
Answer: 2 foot-candles
Security standards generally recommend at least 2 foot-candles of illumination along perimeter boundaries to deter and detect intrusions.
Which type of fence topping provides the GREATEST deterrence against climbing at a minimum cost?
Answer: Razor wire coils
Razor wire coils (concertina wire) provide greater deterrence than standard barbed wire because the razor edges inflict injury and are difficult to compress.
In a biometric access control system, what does the term 'False Rejection Rate' (FRR) measure?
Answer: The rate at which authorized users are denied access
FRR (Type II error) measures how often a legitimate, enrolled user is incorrectly denied access by the biometric system.
