Controlled Unclassified Information (CUI) is a federally defined information category managed under an executive branch cybersecurity program established by Executive Order 13556 and implemented through 32 CFR Part 2002. Effective CUI compliance depends on two fundamentals: recognizing CUI and handling…

Step 1 Goal: Identify CUI (without guessing) Executive Order 13556 establishes a government-wide program for managing unclassified information that requires safeguarding or dissemination controls under law, regulation, or Government-wide policy. Importantly, the Order excludes both classified information under Executive Order…

After identifying Controlled Unclassified Information, the next compliance challenge is scope. Many NIST SP 800-171 failures do not stem from missing controls, but from an undefined or poorly defended CUI system boundary. Without a clear inventory and boundary, organizations often…

CUI marking errors are one of the most common and most preventable sources of compliance risk. Even when organizations correctly identify CUI and scope their systems, inconsistent or incorrect markings can undermine handling controls and create downstream confusion. Step 3…

After identifying CUI, defining your CUI system boundary, and applying proper markings, the next step is operational: NIST SP 800-171 implementation. This is where policy becomes control execution, and where many organizations either build a defensible program or create documentation…

Implementing security controls is only half the job. The next step is validation. A structured NIST SP 800-171A assessment allows you to determine whether your NIST SP 800-171 requirements are implemented correctly, operating as intended, and satisfying CUI security requirements.…

After implementing and assessing NIST SP 800-171 controls, some organizations encounter an additional layer of security expectations. This is where NIST SP 800-172 requirements come into play. This post covers Step 6 of the CUI Compliance Series and explains what…

After working through identification, marking, scoping, implementation, assessment, and enhanced requirements, the final step is consolidation. This post brings everything together into a single, actionable CUI compliance checklist aligned with real contract requirements and reporting obligations. This wrap-up serves as…
