How it is used
Programs count "Owns internet-facing or critical systems" per person from Vulnerability management and read it beside the other Endpoint and device signals; it feeds 1 cohort, 0 sequences and 1 breach scenario.
A "owns internet-facing or critical systems" record is evidence of what the person could expose (the access side of the model). It describes reach; it records no action by the person and no attack under way.
