Rational security

Bruce Schneier is a rare breed of security expert: someone who understand the math and technology of modern day security, but who also understands the other key element, which is the human dynamic. On People, the Death of Privacy, and Data Pollution is a great short article filled, as usual, with loads of common sense. Like this opening passage, for example:

Security is a lot more about people than technology. One thing I've learned from studying economics, the psychology of risk, security, and people is that those problems are actually way harder than the tech problems. We have as much technology as we need, but securing the people end is hard.
