CMMC Documentation Bundle: What You Need Before an Assessment

You’ve done the self-assessment. You’ve built your POA&M. But before any CMMC assessor shows up (virtually or in person), there’s one more crucial step: getting your documentation in order.

Why? Because even if your controls are in place, if you can’t prove it, you

Your CMMC Documentation Bundle Checklist

Below are the core documents assessors expect to see. Miss one, and your audit could stall — or fail.

🔹 1. System Security Plan (SSP)

Your foundational document. It details:

  • Your system boundaries
  • How each NIST 800-171 control is implemented
  • Key personnel and security roles
    🛠 Tip: Align this tightly with your data flow diagram and POA&M.

🔹 2. Plan of Action & Milestones (POA&M)

Your active roadmap for resolving known gaps:

  • Each incomplete control
  • Assigned owners and due dates
  • Realistic, tracked remediation tasks

🔹 3. Data Flow Diagram (DFD)

Shows where CUI/FCI enters, exits, and flows through your system. It supports:

  • Scoping
  • Network boundary definition
  • Identifying trust zones and external interfaces

🔹 4. Policies & Procedures

You’ll need documented policies that reflect actual practices:

  • Access Control
  • Incident Response
  • Configuration Management
  • Media Protection
  • Personnel Security
    🎯 Make sure these are approved, version-controlled, and enforced.

🔹 5. Evidence Artifacts

Assessors want proof — not promises. Have ready:

  • Security awareness training records
  • Screenshots of MFA implementation
  • Audit logs
  • Vendor contracts or SLAs
  • Change management tickets

🔹 6. Asset & Inventory Lists

Required for identifying system components:

  • Hardware inventory
  • Software inventory
  • Cloud assets
    💡 Include version numbers, locations, and ownership if possible.

🔹 7. SPRS Submission Confirmation

If applicable, have proof of your self-assessment score uploaded to the Supplier Performance Risk System (SPRS).

🧠 Final Reminder:

CMMC compliance is not just about what you do — it’s about how well you can prove it. Your documentation tells your compliance story.
