How SpiceDB Secures Authorization for AI
Blog post from AuthZed
SpiceDB is an authorization system designed to make precise and consistent authorization decisions by modeling relationships as a graph of objects, relations, and permissions. It separates authorization data from application data and evaluates permissions against a typed schema, ensuring systems maintain access consistency even amid changes. SpiceDB's model supports complex permission derivation through objects like users, agents, and tasks, and employs a primary enforcement API, CheckPermission, to handle high-traffic workloads. It incorporates caveats for context-based conditions and uses ZedTokens to maintain data consistency, protecting against security failures due to outdated information. By representing delegation as relationship data, SpiceDB enables secure and explicit delegation policies, while its Watch API supports real-time updates for audit and indexing purposes. SpiceDB focuses solely on authorization, providing a shared system across various components without handling identity authentication or runtime isolation, ensuring that permissions are consistently enforced across diverse environments.
