An application is installed on a computing device from an application package. An origin of the application (e.g., a managed installer for an enterprise, a reputation checking service) is propagated to files written to a storage device of the computing device as part of the installation, such as by writing origin information to the storage device as metadata associated with the file. The origin information for a file, in conjunction with a policy on the computing device specifying one or more trusted origins for applications on the computing device, is used to identify whether a particular action can be taken with and/or by the file. These actions can include, for example, execution of an application from an executable file. If the origin information for a file indicates an origin that is a trusted origin specified by the policy, then the action can be performed.
