Crosswalk pair

ISO/IEC 42001 and NIST SP 800-171, control by control

2 canonical controls in Keel’s library satisfy clauses of both ISO/IEC 42001 and NIST SP 800-171. Implement each once, attach the evidence once, and it counts toward each standard. The overlap is the work you don’t repeat.

The overlap

What the two libraries have in common

Every figure here counts canonical controls in Keel’s library, not clauses of either standard. Each standard’s own authored count is on its framework page.

Controls that satisfy both

Canonical controls that crosswalk to at least one clause of each.

38

In Keel’s library for ISO/IEC 42001

5% of them also map to NIST SP 800-171.

41

In Keel’s library for NIST SP 800-171

5% of them also map to ISO/IEC 42001.

    2 controls of 41 in Keel’s library for NIST SP 800-171 also map to ISO/IEC 42001.

The mapping

Controls that satisfy both

Each row is one control in Keel’s library and the clauses it answers on each side. Do the work once; both columns are then evidenced by the same artifacts.

Governance & Risk
Internal audit program A risk-based internal audit program evaluates conformity and effectiveness at planned intervals, and again when an environmental or operational change could have undermined what was last evaluated; each evaluation covers both technical testing and non-technical review of whether the documented policies and procedures are actually being met. The program itself is written down - how often audits run, what methods they use, who is responsible for them, what each one covers and how it reports - and nobody audits their own work, so a finding is an independent judgement rather than a self-assessment. The results of each audit go to the management responsible for the area audited, and the program and its results are retained as evidence that it ran. It rests on a documented assessment, authorization and monitoring policy with supporting procedures, issued to the roles it binds, owned by a named official, and reviewed and updated on a defined cadence. Independence is a property of the assessor and not only of the reporting line: assessments are carried out by assessors or assessment teams with no responsibility for what they are assessing and no stake in the result - internal to the organization but outside the area, or brought in from outside it - and the organization states what level of independence it requires before the assessment is commissioned rather than judging it afterwards. That independence extends to the ongoing case as well as the scheduled one: where controls are monitored continuously between audits, independent assessors monitor them too, so the periodic audit is not the only unbiased look the organization ever takes. What an evaluation produces is treated as an input to improvement and not only as a conformity verdict: the findings, the observations and the opportunities each audit identifies are recorded as improvements with owners and dates and carried into the organization’s improvement process, so an audit changes something rather than closing. 9.2 3.12.1
Nonconformity & corrective action (CAPA) When something fails to meet a requirement, the first response is to contain it: the nonconforming output is controlled so it goes no further, what has already gone wrong is corrected, and the consequences of it are dealt with. Then the question of cause is asked - why it happened, and whether the same failure exists somewhere else or could happen somewhere else - and where the answer warrants action, that action is taken and tracked to closure. Each failure is rated for how serious it is and put in front of the people who actually have the authority to fix it, on a timescale set by that rating rather than by the next scheduled meeting - and where the rating warrants it, that includes senior management and the governing body. Afterwards the action is reviewed for whether it actually removed the cause rather than only for whether it was completed, the management system is changed where the review shows it has to be, and the nonconformity, what was done about it and the result of doing it are all recorded. Open findings are held in one plan of action rather than in the report each came from: a single tracked list carrying every weakness and deficiency the organization has found - from an assessment, an audit, a scan, a test, an incident or a report from outside - with the remediation intended for each, the milestones it will pass and the date it is due, updated as findings are closed and as new ones arrive rather than rebuilt at the next review. 10.2 3.12.2

Beyond the pair

Where else this work counts

A framework is lit when a shared control above also maps to it. Unlit means none of them do — an absence, not a judgment about that standard.

The thesis

Why this is one project, not two

On a crosswalk-native model, NIST SP 800-171 mostly lights up controls you already built for ISO/IEC 42001. You’re not re-uploading the same screenshot for a second audit. You apply the framework and see the genuine delta worth working. That’s the whole idea behind collect once, comply everywhere.

Next step

Add NIST SP 800-171 to the work you already did

Apply both frameworks in one workspace and see the overlap measured against the controls you already hold.
