Vital Area Analysis
Not every room is a vital area, and treating them all as one spends the protective budget on the wrong doors. GSS traces consequence back to its source to identify the areas that actually require it.

A vital area is a location containing structures, systems, or components whose sabotage could cause an unacceptable consequence — radiological, safety, or mission. Determining which locations meet that bar, and which do not, is a modeling exercise, not a walkthrough judgment call.
GSS traces sabotage logic from equipment failure through to consequence, screening systems and structures against a defined consequence threshold and aggregating the locations that contribute into a minimum candidate set of vital areas. The goal is precision: enough area protected to eliminate the consequence pathway, not more than that.
The resulting vital area set is the direct input to target set identification at the equipment level, and to the protective strategy — barriers, detection, response — built around it.
