Users should plan their compartmentalization with this in mind. We should also mention that Qubes has long supported the secure virtualization of a certain class of USB devices, specifically mass storage devices such as flash drives and external hard drives and, more recently, USB mice. Please note that it is always preferable to use these special, security-optimized protocols when available rather than generic USB passthrough.
Eye-candy-wise, we have switched from KDE to Xfce4 as the default desktop environment in dom0. The reasons for the switch are stability, performance, and aesthetics, as explained here. While we hope the new default desktop environment will provide a better experience for all users, Qubes 3. For other features and improvements, please see the release notes.
Post-install, you will be able to switch between them and install others. On the software selection tab, you can choose which software to install in Qubes OS. Two options are available:. Whonix lets you route some or all of your network traffic through Tor for greater privacy.
Depending on your threat model, you may need to install Whonix templates right away. Regardless of your choices on this screen, you will always be able to install these and other templates later. By default, Qubes OS comes preinstalled with the lightweight Xfce4 desktop environment. Other desktop environments will be available to you after the installation is completed, though they may not be officially supported see Advanced Topics.
Under the System section, you must choose the installation destination. Select the storage device on which you would like to install Qubes OS.
The installation destination must have a least 32 GiB of free space available. Installing an operating system onto a USB drive can be a convenient way to try Qubes. We recommend a very fast USB 3.
Please note that a minimum storage of 32 GiB is required. Bear in mind that the installation process is likely to take longer than it would on an internal storage device. As soon as you press Done , the installer will ask you to enter a passphrase for disk encryption. The passphrase should be complex.
Make sure that your keyboard layout reflects what keyboard you are actually using. While the installation process is running, you can create your user account. This is a purely local, offline account in dom0. By design, Qubes OS is a single-user operating system, so this is just for you. Select User Creation to define a new user with administrator privileges and a password. Just as for the disk encryption, this password should be complex.
The root account is deactivated and should remain as such. When the installation is complete, press Reboot. By default, the installer will create a number of qubes depending on the options you selected during the installation process.
These are designed to give you a more ready-to-use environment from the get-go. This configuration process may take a while, depending on the speed and compatibility of your system. What the experts are saying. It's what I use, and free. Software thinks that it's in control, that it can do what it wants? It can't. I'm in control. Can wholeheartedly recommend.
