SSP
System Security Plan: a document describing a system's boundaries, the controls it implements, and how each control is satisfied.
An SSP (System Security Plan) is the core artifact in NIST SP 800-53/800-171-based assessments (including FedRAMP and CMMC). It describes the system boundary, the environment, and, control by control, how the requirement is met, by whom, and with what evidence. Assessors evaluate the SSP against the actual environment.
