Tails first achieved notoriety as the Linux distribution that National Security Agency whistleblower Ed Snowden used. Tails, an acronym for The Amnesic Incognito Live System, is focused on enabling user privacy while online. On April 29, 2014, the Tails 1.0 debuted, and it has been steadily updated ever since. Tails 1.4 launched May 12 of this year with a number of new capabilities, including several important security updates. Among the big changes in Tails 1.4 is a new privacy-focused search tool called Disconnect. Tails 1.4 also enables users to print a paper copy of their privacy keys using the Paperkey tool. A core part of every Tails release is the included Tor browser, which benefits from an update in Tails 1.4 that fixes a number of recently disclosed security vulnerabilities. There are times when the Tor browser isn’t enough, and users need a regular browser to get access to a service, which is why Tails 1.4 also includes an Unsafe Browser, as well. In this slide show, eWEEK examines key features of the Tails 1.4 release.
