NIST, the NSA and CISA have published ten voluntary key practices for handling incidents in which AI agents take significant uninstructed actions during frontier model training and evaluation

What did the three agencies publish?

On 16 October 2026 NIST CAISSI, the NSA's Super Intelligence Security Center and CISA published ten key practices for managing potential incidents during frontier AI training and evaluation. NIST's page describes the document as "voluntary" and says it supports "the frontier SI industry in preventing, preparing for, and responding to incidents during training and evaluation".

The practices are grouped into five stages of the incident management lifecycle. Prepare has two practices (technical controls; organizational and personnel readiness). Detect has two (monitor for unexpected activity; validate and secure the monitors). Respond has two (evidence; shutdown). Recover has one (verify containment before resuming agent activity). Report has three (coordinate with affected parties, notify government, share information publicly).

NIST says the work responds in part to a recommendation in the White House's 2025 action plan that NIST promote incident-response actions for AI within existing incident response doctrine. The page quotes that recommendation; we have not opened the action plan itself.

What counts as an "SI control incident"?

The document defines it as an occurrence in which one or more agents takes "significant uninstructed actions that compromise explicit or implicit policies, controls, or security measures imposed by the operator to define the intended task scope or to ensure human oversight." It may arise in development, evaluation or use, and may or may not affect an outside party.

A companion term, the "control near-miss", covers an occurrence that "presented a reasonably foreseeable or imminent risk" of becoming a control incident. Several practices apply to near-misses as well as incidents.

The definition draws a line, and the line is easy to miss. "uninstructed" means the agent was not directed to act by its operator or by any adversarial source. A footnote gives the example: actions resulting from an adversarial prompt injection or an intentionally backdoored model are treated as instructed. The document also separates the two incident types by direction. An AI system is the source of a control incident; a system or information is the target of a cybersecurity incident. One event can be both, but the document says the two are not coextensive.

What do the practices ask organizations to do?

Read by stage, the text is operational. On preparation: limit agent access to what intended tasks need, restrict network access "via a strict allowlist where possible", and build mechanisms to "rapidly block, contain, or terminate agent activity". Practice 2.6 asks for structured risk assessments before training runs, evaluations or deployments, and says to "Only start or resume if senior leadership, informed by assessments from external evaluators where appropriate, are satisfied with the risk levels."

On detection, the document asks that agents be unable to "access or interfere with monitoring processes and logs" and tells readers to treat monitored model outputs "as potentially containing exploits aimed at the monitors". On response, it calls for tamper-resistant logs that can reconstruct agent trajectories and tool calls, and for automatic shutdown of impacted agent trajectories on detection.

Recovery is where the text is least like a conventional cyber playbook. Practice 7.7 asks that, for incidents during model training, recovery procedures "neither reinforce patterns of activity that led to the control incident nor make future adverse activity more difficult to detect," and gives as an example training against explicit adverse chain-of-thought reasoning in a way that reduces monitorability. Before resuming agent activity, practice 7.5 asks teams to document the recovery decision and the remaining risks.

What does the reporting stage say about disclosure?

The Report section keeps legal duties and voluntary steps apart. Practice 9.1 says to "Adhere to any applicable legal reporting requirements," including cybersecurity incident reporting to CISA and law enforcement, and to report cybersecurity incidents or near-misses arising from control incidents to CISA voluntarily "as appropriate". Beyond naming reporting obligations to CISA, law enforcement and cyber-defense organizations as examples, the document does not identify which legal regimes apply.

Practice 9.3 asks organizations to share AI-specific information about control incidents and near-misses with government experts at NIST CAISSI and NSA SISC, "after carrying out any legally mandated reporting." The sequence matters to a lawyer: the voluntary channel is placed behind the mandatory one.

Practices 10.1 to 10.3 point outward. They ask for sharing details with the public "where appropriate, as early as feasible", for access that lets third parties review the incident independently, and for public reports of improvements adopted. The section's own summary says voluntary control incident reports "should focus on the unsanctioned actions taken by the agents and explanations for these actions, rather than system compromise alone."

How could a team use a voluntary document?

What follows is our inference, not the agencies' position. The document gives counsel and security teams a vocabulary that regulators have now seen: a defined incident class, a near-miss class and a ten-item checklist. A team that writes its own incident policy for agent training could map each practice to an existing control and record where it chose a different approach.

Two cautions follow from the text. First, the document says it "does not constitute advice for compliance, regulatory, or legal purposes", so it is a poor candidate to cite as a legal standard of care without counsel's view. Second, it describes itself as a first phase; the "Areas for Future Work" list names incident severity scores, agent identifiers and structured risk assessments as open research, which suggests the practices will be revised.

For enterprise customers of AI vendors, the practical question is contractual: whether a vendor's incident notice terms reach an event the vendor would classify as a control incident rather than a security breach. The document does not address contracts, and we do not either.

What we did not verify

What we opened: the NIST news page (HTML, with its dcterms.created and publishedTime metadata of 2026-10-16) and the full 14-page PDF as extracted by our scraper. The NIST publication dates, practice counts and quotations come from those two documents; the terminology note separately draws on a Treasury proposed rule. We replaced the source's curly quotation marks with straight ones; no words were changed.

What we did not open: the 2025 White House action plan, NIST SP 800-61r3, the Cybersecurity Framework 2.0, the May 2026 NIST workshop materials, any CISA, NSA or NIST announcement outside the NIST page, and the NIST Consortium task group papers. Where we mention them we repeat only what the NIST page says about them.

Terminology: the agencies write "super intelligence" and "SI". Another federal document we read this month (a Treasury proposed rule published in the Federal Register on 26 October 2026) says in a footnote that Executive Order 14434, section 2, requires agencies to use those terms in place of "Artificial Intelligence" and "AI" in certain documents. We did not open the order and have not confirmed that it explains the NIST wording. We used "AI" in our own voice for readability and kept "SI" inside quotations, rather than quietly harmonizing them.

What we refuse to claim: that any company has adopted the practices, that any regulator will treat them as a standard of care, that any incident of this kind has occurred, or that the practices are adequate. We have no denominator for how many organizations they reach. The acknowledgements list companies that gave feedback, including Anthropic; this page was drafted with the assistance of an AI model developed by Anthropic, so we state no view on the quality of the practices and attribute every characterization to the text.
