Abstract
Described is a technology by which access to a resource is determined by evaluating a resource label of the resource against a user claim of an access request, according to policy decoupled from the resource. The resource may be a file, and the resource label may be obtained by classifying the file into classification properties, such that a change to the file may change its resource label, thereby changing which users have access to the file. The resource label-based access evaluation may be logically combined with a conventional ACL-based access evaluation to determine whether to grant or deny access to the resource.
