The strategy of forming layers of protection around an asset or facility is known as:
A.
Secured Perimeter
B.
Defense-in-Depth
C.
Reinforced Barrier Deterrent
D.
Reasonable Asset Protection
Explanation:
B: In the concept of defense-in-depth, 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.
