CMMC System Security Plan (SSP) Template Guide

What a CMMC-ready SSP must contain — boundary, requirement implementations for 15 FAR or 110 NIST 800-171 controls, roles.

Published: September 2026 Compliance · CMMC 8–12 min read

Your System Security Plan (SSP) is the narrative spine of CMMC and DFARS 7012 safeguarding. Assessors (including your own affirming official) sample whether the SSP matches reality. This page is a template structure — columns and sections you should maintain — not a downloadable Word file pretending to be official DoD stationery.

Related: CMMC hub · Checklist · Scoping · 14 domains.

Template ≠ truth: Copy-paste SSPs fail interviews. Every implementation statement should name real systems, owners, and evidence.

Recommended SSP Sections

  1. System / enclave name and purpose
  2. Information types (FCI / CUI categories)
  3. Authorization boundary and diagrams
  4. Roles (ISSO/ISSM equivalents, affirming official, IR lead)
  5. External service providers and shared-responsibility matrix
  6. Requirement-by-requirement implementation (15 or 110)
  7. POA&M references where Conditional status applies
  8. Related policies, procedures, and evidence repositories

How CyberSilo Helps

Keep the SSP Alive Between Affirmations

Connect each requirement row to current evidence so annual affirmation is not a rewrite exercise.

Frequently Asked Questions

Is there an official DoD SSP Word file on this page?

No. We describe required structure. Use your document control system or CSA exports.

Does Level 1 need an SSP?

You still need documented implementation of the 15 FAR basic safeguarding requirements and evidence for self-assessment/affirmation — keep it proportionate but real.

How does POA&M relate to the SSP?

Open items belong in POA&M when Conditional status allows (L2/L3). Level 1 cannot use POA&M.
