Bruce Schneier Security Systems Quotations

A colleague once told me that the world was full of bad security systems designed by people who read Applied Cryptography

History has taught us: never underestimate the amount of money, time, and effort someone will expend to thwart a security system. It's always better to assume the worst. Assume your adversaries are better than they are. Assume science and technology will soon be able to do things they cannot yet. Give yourself a margin for error. Give yourself more security than you need today. When the unexpected happens, you'll be glad you did.

People often represent the weakest link in the security chain and are chronically responsible for the failure of security systems.
