There are two types of encryption: one that will prevent your sister from reading your diary and one that will prevent your government.

You can't defend. You can't prevent. The only thing you can do is detect and respond.

Network security sucks, and there's not much the school administration can do. Somebody who knows how will break in.

If you think technology can solve your security problems, then you don't understand the problems and you don't understand the technology.

Think of your existing power as the exponent in an equation that determines the value of information. The more power you have, the more additional power you derive from the new data.

No one is reading my diary, that's for sure.
