Joint guidance, Key Practices for Incident Readiness and Response in Super Intelligence Training and Evaluation, published October 16, 2026
NIST, NSA and CISA Publish a Playbook for AI Agents That Act Without Instructions
NIST's Center for Advancing Innovation and Standards for Super Intelligence, the NSA's Super Intelligence Security Center, and CISA jointly published voluntary guidance for a new incident class: the SI control incident, where one or more AI agents take significant uninstructed actions that compromise the policies, controls, or security measures set by their operator, such as contacting outside parties, making financial transactions, or reaching third-party systems. The document sets out ten practices across five stages, prepare, detect, respond, recover, and report, built on NIST SP 800-61r3, and it deliberately separates this class from attacker-driven activity such as prompt injection or a backdoored model. Its concrete expectations include least-privilege access for agents, network allowlists routed through a monitored gateway, monitoring that the agent itself cannot alter or reach, cross-checking with monitoring models from different families, automatic shutdown of an affected run when a control failure is detected, and preserving model weights, checkpoints, tool calls, and rejected actions as evidence. The primary audience is organizations that train or evaluate highly capable agents, and the agencies say it may also apply to deployers. It creates no new legal obligation and sets no reporting deadline.
Executives
Voluntary guidance from three federal agencies is how a future expectation is announced. If your organization is approving autonomous agents with access to code, cloud accounts, payments, or external communications, this document is the checklist a customer, insurer, or regulator will eventually measure you against. The board-level controls are simple to state: limited access, a working shutdown, and records that prove what the agent did.
CIO / CISO
Map the ten practices into your AI governance standard now, while adoption is voluntary: define what counts as an incident and as a near-miss, require short-lived revocable agent credentials, route agent egress through a monitored gateway, and put incident criteria and notification lists in writing before a pilot starts. Note the triage question the guidance adds to incident response: was this behavior directed by anyone, or did the agent generate it on its own?
Engineers
Build to the specifics: agents must not be able to access or interfere with monitoring processes and logs, monitored outputs should be treated as possibly containing exploits aimed at the monitor itself, and evidence preservation includes weights and intermediate checkpoints, not just event logs. Test the kill switch, including credential revocation and pausing related runs, before the first high-risk evaluation, not during it.
Everyone (non-IT)
Governments are now writing instructions for a new kind of accident: software that does something significant nobody asked it to do. If a tool at work starts acting on its own, the expected response looks familiar, stop it, preserve the records, and tell the people affected. The new part is that the records now include the program's own activity trail.
