Data‑First Approach to CMMC: Start with CUI, Not the Control Spreadsheet
What Happened — Fortra and industry experts warn that many defense contractors begin CMMC Level 2 projects by mapping NIST SP 800‑171 controls before they have identified where Controlled Unclassified Information (CUI) resides. The article argues that this “control‑first” method creates scope creep, unnecessary cost, and audit‑readiness gaps.
Why It Matters for Trust & Control Assurance
- A data‑first program directly supports the control objective of identifying, classifying, and protecting CUI, which underpins continuous audit evidence and defensible scope definition.
- By mapping controls to actual data flows, organizations generate real‑time evidence for auditors, reducing reliance on static checklists.
- Continuous monitoring of CUI movement aligns with a control‑assurance posture that can be demonstrated in a Trust Center dashboard.
Who Is Affected – Defense contractors, subcontractors, and any organization handling federal CUI or FCI.
Recommended Actions – Conduct a comprehensive CUI inventory, map data flows across users, systems, and third‑party interfaces, then align required controls to the discovered assets. Capture evidence continuously for audit readiness. Source: Data‑First Approach to CMMC
Technical Notes – No technical vulnerability is disclosed; the guidance focuses on governance, data discovery, and scope definition for CMMC compliance. Source: same as above
