The Tails server project is about exploring the + other side of the alternative: avoiding to put private data into + untrusted hands in the first place. + This is made possible thanks to Tor hidden services, that allow users + to offer location-hidden services, and make self-hosting possible in + many threat models. Self-hosting has its own lot of problems, however, + particularly in contexts where the physical security of the hosting + place is not assured. Combining Tor hidden services with Tails' + amnesia property and limited support for persistent encrypted data + allows to protect content, to a great degree, even in such contexts. + In short, setting up a new Tails server would be done by: + + <ol style="list-style-type: decimal"> + <li>Alice plugs a USB stick into a running desktop Tails system.</li> + <li>Alice uses a GUI to easily configure the needed services.</li> + <li>Alice unplugs the USB stick, that now contains encrypted services + configuration and data storage space.</li> + <li>Alice plugs that USB stick (and possibly a Tails Live CD) into the + old laptop that was dedicated to run Tails server.</li> + <li>Once booted, Alice enters the encryption passphrase either + directly using the keyboard or through a web interface listening on the + local network.</li> + <li>Then, Bob can use the configured services once he gets a hold on + the hidden service address.
