Amazon Verified Permissions now supports Cedar 4.5 . This enables customers to use the latest Cedar features, including the “is” operator, which allows customers to grant access based on resource types. For example, in a petstore application, you can use the “is” operator to write a policy that only grants administrators permission to view a resource if that resource “is” an invoice. This addition enhances Cedar’s type system and helps catch potential type-related errors early in policy development. You can learn about other enhancements to Cedar on the Cedar releases page.
Amazon Verified Permissions is a permissions management and fine-grained authorization service for the applications that you build. Amazon Verified Permissions uses the Cedar policy language to enable developers and admins to define policy-based access controls using roles and attributes.
Amazon Verified Permissions supports Cedar 4.5 in all AWS Regions where the service is available. All new accounts and backward-compatible accounts have been automatically upgraded to Cedar-4, and no additional actions are required.
