CUI Handling Practices for Repeatable CMMC Compliance

February is recognized as Information Governance Month, with February 19 marking Global Information Governance Day.

For organizations supporting federal contracts, information governance defines how Controlled Unclassified Information (CUI) is identified, categorized, documented, and maintained. It establishes accountability and lifecycle controls that support consistent implementation of CMMC Level 2 requirements.

Information governance answers foundational questions:

What qualifies as CUI under contract?
Where does that information reside?
Which systems process, transfer, or store it?
Who is responsible for oversight?
How is it securely disposed?

Clear answers to these questions reduce ambiguity and prevent inconsistent handling of regulated information.

Governance and Regulatory Alignment

DFARS 252.204-7012 requires contractors to provide adequate security for covered defense information (CDI) and to report cyber incidents to DoD. “Adequate security” is defined as implementation of the security requirements in NIST SP 800-171.
NIST SP 800-171 establishes 110 security requirements for protecting CUI in nonfederal systems and organizations.
Cybersecurity Maturity Model Certification (CMMC) formalizes how those requirements are assessed. At Level 2, it evaluates implementation of the 110 NIST 800-171 requirements through third-party assessment.
NIST SP 800-171A provides the assessment procedures. It explicitly instructs assessors to examine, interview, and test to determine whether requirements are implemented and whether evidence demonstrates consistent execution. It is not enough for a control to exist conceptually; it must be institutionalized and demonstrable.
Defined data categorization, documented system inventories, and assigned ownership reduce uncertainty during assessment and support defensible outcomes. In practice, that governance layer is what separates a paper implementation from an assessable one.

Governance Across the Information Lifecycle

Information governance applies across the full lifecycle of CUI — from receipt or creation through processing, storage, transmission, archival, and destruction. Structured processes for handling Controlled Unclassified Information (CUI) ensure consistency across departments and systems.

DoD Instruction 8500.01 reinforces cybersecurity as an integrated operational responsibility across the enterprise. Governance provides the structure that aligns contracts, operations, and technical safeguards.

When governance is clearly documented and consistently applied, organizations are better positioned to:

Maintain accurate system inventories
Track CUI data flows
Demonstrate ownership of compliance artifacts
Support repeatable CMMC assessment readiness guidance
Sustain compliance as environments evolve

Governance as Part of a Sustainable Security Program

Security programs are most effective when structure precedes implementation. Governance establishes the framework within which scoping decisions, control placement, and audit preparation occur.

Clear documentation, defined ownership, and lifecycle management practices reduce unnecessary complexity and support predictable compliance outcomes.

On Global Information Governance Day, the focus is practical:

Define regulated information.
Document responsibility.
Maintain lifecycle consistency.
Support measurable compliance.

Information governance provides the structural foundation for focused, sustainable CMMC compliance.
