CISA and NIST Publish Draft Guidelines for Securing Authentication Tokens

CISA and NIST Release Draft Security Guidelines for Authentication Tokens

The Cybersecurity and Infrastructure Security Agency (CISA) and the National Institute of Standards and Technology (NIST) have published a draft of Interagency Report (IR) 8597, Protecting Tokens and Assertions from Tampering, Theft, and Misuse, for public review and comment. The document aims to strengthen security practices around authentication tokens and assertions, which are critical components in identity and access management (IAM) systems.

Key Details

The draft report, released on December 22, 2024, provides guidance for federal agencies and private-sector organizations on mitigating risks associated with token-based authentication. It addresses vulnerabilities such as:

• Token tampering (unauthorized modification of tokens)
• Token theft (interception or exfiltration of credentials)
• Token misuse (exploitation of stolen or forged tokens)

While the report is not yet finalized, it reflects a collaborative effort between CISA and NIST to standardize security controls for tokens used in OAuth 2.0, OpenID Connect, SAML, and other authentication protocols. The public comment period allows stakeholders to provide feedback before the final version is published.

Technical Focus

IR 8597 outlines best practices for:

• Token generation and validation (ensuring cryptographic integrity)
• Secure storage and transmission (protecting tokens in transit and at rest)
• Monitoring and revocation (detecting and responding to token compromise)

The report also emphasizes the importance of zero-trust architecture and continuous authentication as part of a layered defense strategy. While no specific CVE IDs are referenced, the guidance aligns with existing NIST standards, including SP 800-63 (Digital Identity Guidelines) and SP 800-207 (Zero Trust Architecture).

Impact and Next Steps

Authentication tokens are a prime target for threat actors, as their compromise can lead to lateral movement, privilege escalation, and data breaches. The draft report serves as a resource for security teams to:

• Assess current token security practices
• Implement stronger controls for token lifecycle management
• Align with federal cybersecurity requirements

Public comments on IR 8597 are open until [insert deadline if available]. Organizations are encouraged to review the draft and submit feedback via CISA’s resource page.

For security professionals, this draft represents an opportunity to shape future federal guidelines on token security and ensure alignment with industry best practices.
