Mechanisms are disclosed that allow for execution of unsigned content and the securing of resources in a closed system when such unsigned content is executing on the system. For example, an access layer is used between an ope rating system layer of the closed system and the actual unsigned content. Th is access layer may contain various sub-layers, such as a graphics layer, an audio layer, an input layer, and a storage layer. These layers can control access that the unsigned content can have to the native operating system lay ers and the associated resources of the closed system. By providing such an access layer, unsigned content, e.g., video games, can run on the closed sys tem that is typically designed to run only signed content.
