    • 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.
    • 描述了一种系统和方法,通过该系统和方法,基于其相对于节目类别请求的许可和/或特权来评估应用程序的可信度。 该程序描述了操作所需的权限,并将其标识为属于特定类别。 安全组件将请求的权限集与该类别的程序实际需要的权限进行比较,以便正常运行。 需要更多权限的程序被认为是不可信赖的。 例如,屏幕保护程序应用程序只需要有限的权限集来正常运行,包括全屏访问和读取文件的能力,但不需要网络访问权限或写入对文件的访问权限。 任何只要求所需权限集的屏保应用程序都被认为是可信赖的,而其他请求权限超出实际需要的则不被认为是可信赖的,用户或自动化策略进程可能会进行干预。
