1. A computer-implemented method for accessing a resource in a computer system comprising an operating system, comprising: receiving a request to access a named abstraction from an application; determining if the application is running in a derived user account (DUA) context, wherein the DUA context represents a security context of a DUA that is derived from an original user account (OUA) associated with a user, and wherein the determining comprises examining an access token associated with the request to determine if the request is associated with the DUA; if the application is not running in the DUA context, creating the DUA and directing the application to run in the DUA context; and granting the application access to the named abstraction.
