Qubes lets the user define many security domains, which are implemented as lightweight Virtual Machines (VMs), or “AppVMs.” For example, the user can have “personal,” “work,” “shopping,” “bank,” and “random” AppVMs and can use the applications within those VMs just as if they were executing on the local machine. At the same time, however, these applications are well isolated from each other. Qubes also supports secure copy-and-paste and file sharing between the AppVMs, of course.

It is always clearly visible to which domain a given window belongs. Here it’s immediately clear that the passphrase-prompting window belongs to some domain with the “blue” label. When we look at the titlebar, we see “[qubes]”, which is the name of the actual domain. Theoretically, the untrusted application (here, the red Tor Browser running in a DisposableVM) beneath the prompt window could draw a similar looking window within its contents. In practice, this would be very hard, because it doesn’t know, e.g., the exact decoration style that is in use. However, if this is a concern, the user can simply try to move the more trusted window onto some empty space on the desktop such that no other window is present beneath it. Or, better yet, use the Expose-like effect (available via a hot-key). A malicious application from an untrusted domain cannot spoof the whole desktop because the trusted Window Manager will never let any domain “own” the whole screen. Its titlebar will always be visible.

Note that the user is not required to shut down any AppVMs (domains) for the update process. This can be done later, at a convenient moment, and separately for each AppVM.
