  • Patent number: 11902327
    Abstract: Techniques are described herein that are capable of evaluating a result of enforcement of access control policies instead of enforcing the access control policies. For instance, a result of enforcement of an access control policy with regard to sign-in processes is evaluated instead of enforcing the access control policy with regard to the sign-in processes. The evaluation includes monitoring access requests that are received during the sign-in processes. Each access request requests access to a resource. The evaluation further includes comparing attributes of each access request against the access control policy that specifies criteria that are to be satisfied as a prerequisite to granting access to the resource to which access is requested by the respective access request. Metadata associated with the sign-in processes is generated instead of enforcing the access control policy with regard to the sign-in processes.

  • Publication number: 20230254321
    Abstract: Generally discussed herein are devices, systems, and methods for adaptive authorization using a local route as a named location. A method can include defining a local route and a corresponding local route endpoint, associating a compute resource as a destination of the local route endpoint, defining an adaptive authorization policy that limits access to the compute resource to be through the local route endpoint, and enforcing access to the compute resource based on the defined adaptive authorization policy.

  • Patent number: 11405425
    Abstract: Authenticating computing entities. A method includes at an identity provider, providing a first access token to an entity for use by the entity in obtaining resources from a resource provider. The method further includes, at the identity provider, receiving response information from the entity. The response information from the entity is provided to the entity from the resource provider as a result of the resource provider enforcing policy at the resource provider. At the identity provider, a second access token is provided to the entity. The second access token is provided based on the response information, such that the second access token can be used by the entity to obtain the resources from the resource provider.

  • Publication number: 20210136114
    Abstract: Implementing policy at a resource provider computer system. The method includes a resource provider computer system receiving policy from an identity provider system, the policy being related to an entity that authenticates using the identity provider computer system. The resource provider computer system receives a request for resources from the entity and an access token from the entity. The access token was obtained by the entity from the identity provider computer system as a result of the entity authenticating with the identity provider computer system. The resource provider computer system evaluates the request with respect to the policy. The resource provider computer system responds to the request based on evaluating the request with respect to the policy.

  • Patent number: 10873583
    Abstract: Methods, systems, and apparatuses in a computing device enable user access to a resource. The method includes receiving, from a user, a request for access to a resource; accessing an authentication flow for granting access to the resource; obtaining first claims for a user from a first claims provider in the authentication flow; determining a second claims provider in the authentication flow, the second claims provider having a trust relationship with the claims facilitator; directing the user to the second claims provider; receiving second claims for the user from the second claims provider; and enabling the user to access the resource in response to at least the received first and second claims.
