Protecting Tokens and Assertions from Forgery, Theft, and Misuse: Implementation Recommendations for Agencies and Cloud Service Providers

The document titled "Protecting Tokens and Assertions from Forgery, Theft, and Misuse" provides guidelines developed by the National Institute of Standards and Technology (NIST) and the Cybersecurity & Infrastructure Security Agency (CISA) for federal agencies and cloud service providers. It addresses the protection of identity assertions and access tokens, which are crucial for modern authentication.

The guidelines highlight various risks associated with these tokens, especially in hybrid and multi-cloud environments, where communications involve signed tokens vulnerable to forgery and misuse. The report includes updated recommendations based on stakeholder feedback and emphasizes principles such as Secure by Design to enhance security across cloud environments.
