A new civic records annex needs layered physical protection from the property line inward. Which control pairing best matches perimeter versus internal needs?
Select an answer to reveal the explanation.
Short Explanation
Yard first, then rooms. Fences, lights, and cameras watch the edge; locks, guards, and sensors harden the inside. One fancy camera alone is not a layered civic facility.
Full Explanation
Physical security is implemented in layers: perimeter controls such as fencing, lighting, and external cameras deter and detect approach, while internal locks, guards or patrols, and sensors protect rooms and assets of higher sensitivity. Civic facilities holding records or public-service infrastructure should not depend on a single exterior device or desk badge alone. Differentiating perimeter and internal controls aligns protection with exposure and asset value. Defense in depth in the physical domain mirrors the same principle used in logical security.
