ABSTRACT
The primary goal of a physical protection program is to control access into the facility. In this concept, barriers are arraigned in layers with the level of security growing progressively higher as one comes closer to the center or the highest protective area. Defending an asset with a multiple posture can reduce the likelihood of a successful attack; if one layer of defense fails, another layer of defense will hopefully prevent the attack, and so on. This design requires the attacker to circumvent multiple defensive mechanisms to gain access to the targeted asset.
