A policy engine validates one or more security tokens in an authenticated request using a sequence of partial policy validations. Multiple policies may be applied to the security token using the work product generated from each failed policy. The policy that succeeds in validating the security token has a portion of its work performed through previously-failed policies that did not complete successfully. In this manner, the validation of a policy is performed faster and more efficiently since the previous processing is not repeated whenever a new policy is applied.

Security token validation using partial policy validations

Methods for hardening security between web services using protected forwarded access tokens are implemented via systems and devices. User applications receive user tokens with user information from an identity provider and provide the user tokens to first services with data requests. Each first service extracts and transforms a portion of a user token to validate a user token signature, and determines a target service for the data request. The first services acquire actor tokens from the identity provider that uniquely identify the first services using public keys, and then generate authentication tokens, signed with corresponding private keys, that encapsulate the actor tokens and the transformed user tokens. The signed authentication tokens are provided to target services which validate the authentication tokens as well as the encapsulated tokens and their respective signatures. Upon validation, requested data is retrieved and provided back for the user applications from the target services.
