A commodity laptop is analyzed to identify exposed attack surfaces and is then secured on both the hardware and the firmware level against permanent modifications by malicious software as well as quick drive-by hardware attacks by evil maids, ensuring that the machine always powers up to a known good state and significantly raising the bar for an attacker who wants to use the machine against its owner.
I bought an Thinkpad x60s in order to harden it against people trying to backdoor the machine when i'm shorter than 20 minutes away from my laptop. This page will document what I have done and how you can do the same thing and not brick your system!
