  • Target-based access check independent of access request
    Patent number: 8561152
    Abstract: A context of a principal is built, at a target system controlling access to a resource, independently of the principal requesting access to the resource. An authorization policy is applied, at the target system, to the context to determine whether the principal is permitted to access the resource, and an indication of whether the principal is permitted to access the resource is provided (e.g., to an administrator). Modifications can be made to the context and the authorization re-applied to determine whether a principal having the modified context is permitted to access the resource.
