Abstract
A pattern matching access control system determines whether a principal should be granted access to use a resource based on properties of applications comprised by the principal. The principal name may be created when an application is loaded, invokes other applications (or programs) and/or assumes a new role context. Access is provided based on whether, for each application, the publisher is authorized by system policy to grant privilege as requested by the application. When a resource which requires the privilege is requested by a principal, an access control list (ACL) for the resource is expanded with a list of applications that have been authorized through their publisher to assert the privilege. The expanded ACL is compared to the principal name to determine resource access.
