occupyOS is a specialized Linux distribution designed to provide a secure environment activists can use to edit and publish documents, browse the web (manage site, twitter, and facebook pages), and securely communicate both on the ground and with the outside world. It was designed with security and usability in mind.
Tails is a live CD or live USB that aims at preserving your privacy and anonymity. It helps you to:
- use the Internet anonymously almost anywhere you go and on any computer:
- all connections to the Internet are forced to go through the Tor network;
- leave no trace on the computer you're using unless you ask it explicitly;
- use state-of-the-art cryptographic tools to encrypt your files, email and instant messaging.
NOTE: occupyOS is still under heavy development and an official stable release has not been made.
Other options: Backtrack, Dynebolic, FreeBSD and Debian
