An SSP captures scope, architecture, and control implementations to demonstrate how security requirements are addressed.

Working Definition

System Security Plan describing implemented controls and system boundaries.

Why This Term Matters

SSP appears frequently in buyer requests, contract language, and assessment prep work. Teams should align on a consistent internal definition so scope decisions, artifact quality, and remediation priorities remain stable across technical and non-technical stakeholders.

Operational Use in CMMC Programs

When teams reference SSP, they should also document:

  • Which systems and workflows are affected
  • Which control outcomes are impacted
  • Which evidence artifacts demonstrate implementation
  • Which owner approves updates or exceptions

Common Misunderstandings

Many organizations treat terminology as theoretical rather than operational. In practice, terms like SSP affect architecture, workflows, training, and reporting cadence. Clarifying definitions early reduces rework later in the readiness cycle.
