What are the lines of defense in physical security?

Question

Quizplus · Accepted Answer

The lines of defense in physical security include the perimeter of the facility, the building exterior, and the interior. All three areas need to be secured to ensure the highest level of protection. An intruder who is deterred by the perimeter may attempt to breach the building exterior, and if that fails, they may try to gain access to the interior. Therefore, all three areas are equally important for effective physical security. All of the above - The first line of defense is the perimeter of the facility, which includes fences, walls, gates, and other barriers. The second line of defense is the building exterior, including measures such as access control systems, surveillance cameras, and alarms. The third line of defense is the interior, including locks, access control systems, and surveillance cameras to protect against internal threats. All three lines of defense work together to provide maximum physical security.
