The CCC has published a wiki article that advises its attendees on various practices to help them not get “hacked” during the congress itself. After all, security conferences like these are like warzones. 
The article touches on various aspects of security, including software and physical security. It also has a brief roundup on how to secure each system. Of course, there’s nothing too detailed and it might even be missing a couple of possible attack vectors, but the general idea is there.
