In Site Security Planning and Design Criteria, security expert witness Randall Atlas Ph.D., AIA and Anthony DiGreggario of Atlas Safety & Security Design, Inc. describe design criteria:
Threat: Tactics; weapons, explosives, tools Assets Levels of protection Constraints The result of the assessment will be a set of recommended countermeasures that may be priced and presented to the owner in a priority order so selections may be made of those recommendations that are prudent and cost effective. In the case of the government standards, the assessment results in the assignment of a defined Level of Protection (LOP) with specified countermeasures. When the LOP is defined, the specified countermeasures are priced and again the owner may select appropriate measures depending on a prudent level of protection and the cost effectiveness of the measure.
