Bruce Schneier Quotes

A few years ago I heard a quotation, and I am going to modify it here: If you think technology can solve your security problems, then you don't understand the problems and you don't understand the technology.

The very definition of news is something that hardly ever happens. If an incident is in the news, we shouldn't worry about it. It's when something is so common that its no longer news – car crashes, domestic violence – that we should worry.

Chaos is hard to create, even on the Internet. Here's an example. Go to Amazon.com. Buy a book without using SSL. Watch the total lack of chaos.

The point of terrorism is to cause terror, sometimes to further a political goal and sometimes out of sheer hatred. The people terrorists kill are not the targets; they are collateral damage. And blowing up planes, trains, markets or buses is not the goal; those are just tactics.

The real point of terrorism is not the act itself, but our reaction to the act. And we're doing exactly what the terrorists want.

"How will authors and artists get paid for their work?" they ask me. Truth be told, I don't know. I feel rather like the physicist who just explained to a group of would-be interstellar travelers, only to be asked: "How do you expect us to get to the stars, then?" I'm sorry, but I don't know that, either.

I mean, the computer industry promises nothing. Did you ever read a shrink-wrapped license agreement? You should read one. It basically says, if this product deliberately kills your children, and we knew it would, and we decided not to tell you because it might harm sales, we're not liable. I mean, it says stuff like that. They're absurd documents. You have no rights.

We can't keep weapons out of prisons; we can't possibly expect to keep them out of airports.

Digital files cannot be made uncopyable, any more than water can be made not wet.

Against the average user, anything works; there's no need for complex security software. Against the skilled attacker, on the other hand, nothing works.

Not being angels is expensive
