What are the key differences between NIST SP 800-66 and NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements?

NIST SP 800-66 has 24 controls across its framework, while NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements covers 35 controls. Direct mapping analysis identifies 10 overlapping controls (42% coverage). The frameworks diverge most significantly in NIST SP 800-66: Organizational Requirements, where 4 NIST SP 800-66 controls have no direct NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements equivalent.

How many controls map between NIST SP 800-66 and NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements?

Of 24 total NIST SP 800-66 controls, 10 map directly to NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements controls — representing 42% coverage. The remaining 14 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping NIST SP 800-66 to NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements?

14 NIST SP 800-66 controls have no direct equivalent in NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements. The highest concentration of gaps is in NIST SP 800-66: Organizational Requirements with 4 unmapped controls. These gaps represent areas where additional controls, policies, or documentation must be created to achieve compliance with both frameworks.

Which control domains have the most gaps between NIST SP 800-66 and NIST SP 800-171A Rev 3 — Assessing CUI Security Requirements?

The domain with the highest gap count is NIST SP 800-66: Organizational Requirements (4 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
