What is the NIST AI Risk Management Framework?

The NIST AI Risk Management Framework (AI RMF 1.0) is the voluntary framework published by the US National Institute of Standards and Technology in January 2023 for managing risks associated with AI systems across their lifecycle. It is the closest thing the United States has to an authoritative AI governance standard and is referenced by federal AI executive orders, sector-specific regulators, and most enterprise AI risk programs.

What the framework covers

NIST AI RMF organizes AI risk management around four functions:

  1. Govern — establish policies, accountability, and oversight for AI systems. Includes risk tolerance, organizational roles, supplier management, and a continuous improvement loop.

  2. Map — understand context. What is the AI system, what's it used for, who's affected, what are the legal/ethical/business constraints, what does the deployment look like end-to-end?

  3. Measure — evaluate the system against trustworthiness characteristics. Accuracy, reliability, robustness, security, resilience, accountability, transparency, explainability, privacy, fairness.

  4. Manage — prioritize and respond to risks based on their likelihood and impact. Includes incident response planning, ongoing monitoring, and decommissioning workflow.

These functions are not sequential — they run continuously and feed back into each other.

The seven trustworthiness characteristics

NIST defines a trustworthy AI system as one that is:

Most AI security programs map their controls to these seven attributes plus the four functions, producing a 7×4 matrix used as the assessment framework.

The Generative AI Profile

In July 2024, NIST published a companion document — AI 600-1, the Generative AI Profile — that extends the AI RMF specifically for generative AI systems including LLMs. The profile catalogs 12 risks unique to GenAI:

It is the most-cited reference document for GenAI risk programs in regulated US enterprises.
