The NIST SP 800-171 Rev 3 to AWS Well-Architected Security Pillar crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which AWS Well-Architected Security Pillar controls your existing NIST SP 800-171 Rev 3 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
29 of 63 AWS Well-Architected Security Pillar controls are evidenced by work you have already done for NIST SP 800-171 Rev 3. 34 are genuine gaps.
A sample of what the report says
Incident response plan developed, distributed, reviewed and updated covering CUI compromise.
Grounded in 03.06.05 Incident Response Plan. Confidence high, survived the refutation pass.
Maintain an up to date roster of incident responders, executives, legal, comms, AWS support contacts and external IR retainer firms with on call rotations.
Every one of the 29 evidenced controls and 34 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
42 of 97 NIST SP 800-171 Rev 3 controls are evidenced by work you have already done for AWS Well-Architected Security Pillar. 55 are genuine gaps.
A sample of what the report says
Lifecycle-driven grant and revocation on joiner mover leaver events evidences account creation, modification and removal.
Grounded in SEC03-BP06 Manage access based on lifecycle. Confidence high, survived the refutation pass.
Identify duties that require separation; define system access authorizations to support separation of duties.
Every one of the 42 evidenced controls and 55 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
- Every evidenced control, with the reasoning behind it
- Every gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 72% in the header counts how many NIST SP 800-171 Rev 3 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many AWS Well-Architected Security Pillar 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.
