EU AI ActNIST SP 800-53 Rev 5

EU AI Act covers 8% of NIST SP 800-53 Rev 5

24 of the 300 controls in NIST SP 800-53 Rev 5 are already satisfied by evidence you collected for EU AI Act. 276 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.

genuine gaps

claims rejected in review

This number is directional. It says how much of NIST SP 800-53 Rev 5 your EU AI Act evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.

85 candidate mappings were examined and 0 were removed. Signed off 2026-08-20, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

Where the gaps are

Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.

Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.

Claims that held

A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.

EUAI-Art.19NIST800-AU-11argued against and upheld

Audit record retention

Logs retained at least six months, longer where other Union law requires.

EUAI-Art.12NIST800-AU-12argued against and upheld

Audit record generation

The system must technically allow automatic recording of events over its lifetime.

EUAI-Art.12NIST800-AU-2argued against and upheld

Event logging

Logged event types are fixed by law, with named fields for biometric identification systems.

EUAI-Art.12NIST800-AU-3argued against and upheld

Content of audit records

Records must carry period of use, reference database, input data and persons involved.

EUAI-Art.43NIST800-CA-2argued against and upheld

Control assessments

Formal conformity assessment against a defined procedure before the system may ship.

EUAI-Art.47NIST800-CA-6argued against and upheld

Authorization

Signed declaration of conformity authorises release and assumes responsibility for compliance.

EUAI-Art.72NIST800-CA-7argued against and upheld

Continuous monitoring

Documented monitoring plan collects and analyses performance data throughout the lifetime.

EUAI-Art.20NIST800-IR-4argued against and upheld

Incident handling

Non conformity triggers immediate correction, withdrawal, disabling or recall, with causes investigated.

Claims that did not hold

Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
