Abstract
Described is a system and method by which an application program is evaluated for trustworthiness based on the permissions and/or privileges it requests relative to a program category. The program describes the permissions needed to operate, and identifies itself as belonging to a particular category. Security components compare the requested permission set against the permissions that programs of that category actually need in order to operate properly. Programs requesting more permissions than needed are deemed untrustworthy. For example, screen saver application programs need only a limited permission set to operate properly, including full screen access and the ability to read files, but do not need network access permissions or write access to files. Any screensaver application that requests only the needed permission set is deemed trustworthy, while others that request permissions beyond what is actually needed are not deemed trustworthy, and a user or automated policy process may then intervene.
