NIST AI 600-1 / MS-1.1

MS-1.1: Approaches for AI risk measurement are documented

Defined metrics + thresholds for accuracy, bias, robustness.

Last reviewed June 2026

Problem

The gap MS-1.1 closes

Approaches for AI risk measurement are documented sits in the measure surface, and NIST AI 600-1 rates it high. Defined metrics + thresholds for accuracy, bias, robustness. For teams shipping LLM and agentic features, a control like this is only as good as the evidence that it was actually tested - an unverified control is a finding waiting for an auditor.

How Penaxtra approaches it

How Penaxtra delivers MS-1.1

Penaxtra turns this NIST AI 600-1 obligation into testable, recurring evidence: scheduled scans and posture checks produce findings tied to MS-1.1, and the append-only audit log records what was tested and when, which is exactly what an assessor asks for. Every relevant finding is created with the NIST AI 600-1 MS-1.1 identifier already attached, so it lands in the audit-evidence pack mapped to the control rather than as a screenshot someone has to translate later. Where the same weakness touches another framework, the cross-framework overlap means one finding satisfies several control cells at once.

Findings for MS-1.1 carry the NIST AI 600-1 MS-1.1 identifier and cross-map to the related controls in the other five frameworks Penaxtra covers.

FAQ

Frequently asked

What is MS-1.1 (Approaches for AI risk measurement are documented)?

Defined metrics + thresholds for accuracy, bias, robustness. It is part of NIST AI 600-1, rated high.

How does Penaxtra test for MS-1.1?

Penaxtra turns this NIST AI 600-1 obligation into testable, recurring evidence: scheduled scans and posture checks produce findings tied to MS-1.1, and the append-only audit log records what was tested and when, which is exactly what an assessor asks for.

Does a finding for MS-1.1 help with an audit?

Yes. Each finding is tagged with the NIST AI 600-1 MS-1.1 control identifier and exported in the PDF and JSON evidence pack, so it maps straight onto the auditor control list instead of needing manual translation.
