What does DHS mean by “no credit for any facility or asset security measures” in question D.11?
Question D.11 is asking about achievability probability which refers to the probability that an adversary could execute a successful attack assuming the absence of all security measures at the asset. Achievability is a function of the difficulty for the adversary of the attack type in relation to the specific target asset. For example, the inaccuracy of a standoff weapon or difficulty in loading a large portable container are factors that would reduce the achievability of a standoff attack or theft of a container of COI, respectively, even without considering facility security measures (SVA instructions, page 70).
