One of the trends we've seen is how, as the word of the NSA's spying has spread, more and more ordinary people want to know how (or if) they can defend themselves from surveillance online. But where to start?

The bad news is: if you're being personally targeted by a powerful intelligence agency like the NSA, it's very, very difficult to defend yourself. The good news, if you can call it that, is that much of what the NSA is doing is mass surveillance on everybody. With a few small steps, you can make that kind of surveillance a lot more difficult and expensive, both against you individually, and more generally against everyone.

Here are ten steps you can take to make your own devices secure. This isn't a complete list, and it won't make you completely safe from spying. But every step you take will make you a little bit safer than average. And it will make your attackers, whether they're the NSA or a local criminal, have to work that much harder.
