Heads is an open source custom firmware and OS configuration for laptops and servers that aims to provide slightly better physical security and protection for data on the system. Unlike Tails, which aims to be a stateless OS that leaves no trace on the computer of its presence, Heads is intended for the case where you need to store data and state on the computer. It targets specific models of commodity hardware and takes advantage of lessons learned from several years of vulnerability research. This talk provides a high level overview of Heads, a demo of installing it on a Thinkpad and a tour of some of the attacks that it protects against.
