FDE is nice, but only helps once it's too late. Once someone physically
obtained the disk and being unable to force you to reveal the password.

Yes. Isolating proxy.


My project Whonix is exactly about this topic. Feel free to learn from
the concept, design, source code (configuration files), build it from
source or use the download version.


Physical Isolation. (Tor-Gateway runs on a second piece of hardware.
Server can only connect through the Gateway.)


If you understand Physical Isolation, it is the most safe Tor
configuration. Whonix documentation also gives you a lot inspiration to
further improve security. You could end up with hardened gentoo etc. etc...
