- Bruce is a security technologist. He thinks about security systems and how to break them.
- Bruce tells us how fun security can be—he says we should look at the systems that are around us, understand how they work and how they can be exploited.
- Secret security systems can be easily broken, because even if you can design a system that you can't break, there's a good possibility that someone else can. Good security works even if all its details are public.
- Bruce says to close the book and go hack a security system.
