Abstract
Approaches for securing resources of a virtual machine. An application executes on a host operating system. A user instructs the application to display a file. In response, a host module executing on the host operating system instructs a guest module, executing within a virtual machine, to render the file within the virtual machine. The application displays the file using screen data which was created within the virtual machine and defines a rendered representation of the file. The user is prevented from accessing any resource of the virtual machine unrelated to the file. The virtual machine may consult policy data to determine how to perform certain user-initiated actions within the virtual machine. Examples of the file include image, a document, an email, and a web page.
