A CSC is designing security for a perimeter with a clear zone. What is the purpose of a 'clear zone' (also called a sterile zone) on both sides of a security fence?
Answer: To provide a buffer area free of obstructions that allows guards and sensors to detect intrusions
A clear zone eliminates vegetation and obstructions near a fence line so that intrusion detection systems and security personnel have unobstructed visibility.
Which authentication factor category does a retinal scan belong to?
Answer: Something you are
A retinal scan is a biometric factor categorized as 'something you are,' based on a unique physical characteristic of the user.
A security consultant is evaluating a CCTV system. Which camera feature is MOST important for capturing usable evidence images in a low-light parking lot?
Answer: Low lux / IR illumination capability
Low-lux sensors combined with infrared (IR) illuminators allow cameras to capture clear images in near-darkness, which is critical for parking lot surveillance.
What does 'CPTED' stand for, and what is its core principle?
Answer: Crime Prevention Through Environmental Design — using physical environment design to deter criminal behavior
CPTED uses design elements like natural surveillance, access control, and territorial reinforcement to reduce opportunities for crime.
A high-security facility requires that all visitors be authenticated BEFORE they reach the inner secured area. Which control BEST enforces this?
Answer: A visitor management system integrated with an airlock entry
An airlock (mantrap) integrated with visitor management ensures visitors are identified and authorized before gaining access to the secured inner area.
In access control matrix terminology, what does a 'capability list' represent?
Answer: A list tied to each subject showing the objects they can access and permitted operations (row view)
A capability list is subject-centric, listing the objects a specific subject can access and the operations permitted, essentially a row of the access control matrix.
Which perimeter security measure BEST addresses the threat of drone-based surveillance or payload delivery at a secure facility?
Answer: Counter-UAS (C-UAS) detection and mitigation systems
Counter-UAS systems use radar, RF detection, acoustic sensors, and mitigation tools (jamming, nets, directed energy) to detect and neutralize drone threats.
