NIST and CISA finalize playbook to stop token theft and forgery
NIST and CISA finalized NIST IR 8587, a playbook helping federal agencies and cloud providers defend identity tokens against theft and forgery.
The finalized NIST IR 8587 guidance covers protecting token signing keys, verifying tokens, lifetimes, revocation, session management, and dividing security responsibilities between cloud providers and customers. It cites an incident in which foreign actors forged tokens with a stolen commercial signing key to steal more than 60,000 emails from one government agency. It also recommends extending token protections to AI agents and preparing identity systems for a future post-quantum cryptography transition.
- Recommends cryptographic key protection, strict token verification, and lifecycle controls.
- Cites a forged-token attack using a stolen signing key that stole 60,000+ emails.
- Defines shared responsibilities between cloud providers and customer organizations.
- Extends token protection guidance to AI agents and post-quantum readiness.

NIST and CISA have finalized guidelines to help federal agencies and cloud service providers (CSPs) protect identity and access tokens from forgery, theft, and misuse. The guidance, Protecting Tokens and Assertions from Forgery, Theft, and Misuse (NIST IR 8587), explains how agencies and cloud providers can strengthen key management, token verification, and token lifecycle controls.
