The Physical and Environmental Protection (PE) Policy is the governing artifact that describes how physical access to facilities and environments is managed and controlled. While the SSP provides a system-wide overview, and access lists provide details of who is authorized, it is the PE Policy that explicitly documents the physical access control measures required under CMMC.

Extract from PE.L2-3.10.1:

“Organizations must develop, document, and disseminate physical and environmental protection policies that govern how access to buildings and systems containing CUI is limited to authorized individuals.”
