Name three physical security controls used to protect facilities.

• A. Fire alarms, HVAC, and elevators.
• B. Email filtering, password changes, and training.
• C. Perimeter barriers, lighting, and access control points.
• D. Noise-cancelling headphones, break rooms, and parking decals.

Answer: (C)

Physical security controls are tangible measures that protect a facility by deterring, detecting, and delaying unauthorized entry. Perimeter barriers like fences or walls create a boundary the intruder must cross, raising the effort and risk of getting caught. Lighting around the building enhances visibility at night, making suspicious activity harder to go unnoticed and increasing the chance of a deterrent or quick detection. Access control points—such as secured doors, gates, biometric readers, or badge systems—limit who can enter and help track who moves through restricted areas. Together, these elements form a practical, layered approach to securing a facility’s exterior and entryways. Other options blend in items that don’t directly provide physical protection of the building. For example, some listed items are building services or administrative/technical measures rather than ways to physically restrict or monitor access.
