Token Security

Token security encompasses the technical and procedural safeguards protecting authentication credentials, API keys, and access tokens from unauthorized use or exposure. For enterprise AI systems, compromised tokens can enable attackers to hijack model access, exfiltrate training data, or manipulate AI outputs without detection. Organizations must implement token rotation policies, secure storage practices, and monitoring systems to prevent credential theft and ensure the integrity of AI application authentication.

NIST IR 8587 Leaves AI Agent Authorization Without a Federal Standard

NIST, with CISA support, released IR 8587 covering token lifecycle management, audience restrictions, and continuous monitoring for identity and access tokens. The guidance explicitly excludes AI agent authorization scenarios, acknowledging that agentic systems create IAM challenges requiring separate standards still under development. Enterprises deploying AI agents are advised to treat them as low-trust non-human identities and enforce short-lived credentials while formal guidance remains pending.
