  • Authorization policy evaluation
    Patent number: 12483595
    Abstract: A system and method for authorization policy evaluation. Authorization policies are authored in a general-purpose authorization language. An evaluation engine is used in a provider network by application developers to manage access within their applications based on fine-grained permissions. The policy language combines elements of role-based and attributed-based access control within an intuitive syntax and efficient evaluation strategy. The policy syntax separates role-based expressions of a policy from attribute-based expressions of the policy.

  • Authorization policy validation
    Patent number: 12261888
    Abstract: A system and method for authorization policy validation. A validator takes as input an authorization policy to be analyzed and a schema that specifies entity types and their attributes, types of entity parents in an entity hierarchy, and which entity types can be used with which actions. The validator checks that the policy conforms to the schema. If the check passes, then the policy is guaranteed to be free of both type errors and attribute access errors for any input that conforms to the schema.
