I've become increasingly disturbed by high profile hacks and data breaches.
Maybe I'm wrong, but it looks like these things are getting worse — and when there's a data breach, hack, or privacy violation — the most vulnerable people are hit hardest.
I'm a web dev, thinking about focusing on helping people stay secure online.
What are your tips for becoming a cyber security expert? How can I start learning online?
Second, spend some time watching lectures and presentations from security professionals. I like to watch videos from previous DefCons. Why do this? It'll help narrow down your interests. Think of it as a survey/appreciation class.
Third, spend some money (after proper research) on classes, software, then hardware (in that order). Once you know the software you want to start with (from watching fun lectures) and your focus (pen testing? red hat? blue hat? etc?) you can better focus on your learning.
Fourth lurk then participate in some online forums.
If it weren't a plague season I'd recommend going to a local security professionals slash hacker meetup then a national one. But that's not a good idea at the moment. Regardless, it's a good idea to get to know people. They'll be able to give you more specific advice on where to get a jobby job.

IMHO The most vulnerable people are always hit the hardest. That's what vulnerable means, right?
