Coverage crosswalk

A NIST SP 800-66 Rev 2 to NIST SP 800-53 Revision 5.1 HIGH crosswalk, built to order

The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-53 Revision 5.1 HIGH controls your existing NIST SP 800-66 Rev 2 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.

NIST SP 800-66 Rev 2 into NIST SP 800-53 Revision 5.1 HIGH

Not published yet

This direction has not been through crosswalk review and sign off, so no coverage figure is published for it. Reporting an unreviewed number would be worse than reporting none. It can be built to order at the same price as a pair that is already on the shelf.

If the two frameworks turn out to have too little in common for a crosswalk to help you, we say so and refund it rather than send a number worth nothing.

Why this page shows two different percentages. The 83% in the header counts how many NIST SP 800-66 Rev 2 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-53 Revision 5.1 HIGH controls are actually evidenced, after a pass that argued against each mapping and kept only what survived. They answer different questions and they are not meant to agree.

A crosswalk narrows the work. It does not replace an audit, and your assessor may take a different view on individual controls. Mappings between frameworks are judgements, not text printed in either standard, which is why every claim in the report shows its reasoning. Questions go to support@theartofservice.com.

What are the key differences between NIST SP 800-66 Rev 2 and NIST SP 800-53 Revision 5.1 HIGH?

NIST SP 800-66 Rev 2 has 65 controls across its framework, while NIST SP 800-53 Revision 5.1 HIGH covers 317 controls. Direct mapping analysis identifies 54 overlapping controls (83% coverage). The frameworks diverge most significantly in Administrative, where 8 NIST SP 800-66 Rev 2 controls have no direct NIST SP 800-53 Revision 5.1 HIGH equivalent.

How many controls map between NIST SP 800-66 Rev 2 and NIST SP 800-53 Revision 5.1 HIGH?

Of 65 total NIST SP 800-66 Rev 2 controls, 54 map directly to NIST SP 800-53 Revision 5.1 HIGH controls, representing 83% coverage. The remaining 11 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 Rev 2 to NIST SP 800-53 Revision 5.1 HIGH?

11 NIST SP 800-66 Rev 2 controls have no direct equivalent in NIST SP 800-53 Revision 5.1 HIGH. The highest concentration of gaps is in Administrative with 8 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 Rev 2 and NIST SP 800-53 Revision 5.1 HIGH?

The domain with the highest gap count is Administrative (8 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
