Physical security

Modern prisons are among some of the most physically secure facilities, with almost every area under tight access control and surveillance. Pictured here is the exterior of Shata Prison in Israel, which is secured through the use of high fences, razor wire, protective barriers, guard towers, and security lighting.

Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment, and resources and to protect personnel and property from damage or harm (such as espionage, theft, or terrorist attacks).^[1] Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property.
