Ethical Hacking

Have you guys heard anything about Ethical Hacking?

http://en.wikipedia.org/wiki/Certified_Ethical_Hacker

wiki didn't provide a whole lot of help, but you can find more info through the usual sources. I'm majoring in computer science, and I've heard a lot about how important security is. I'm only a freshman, but down the line I hope to get my masters, and I think the best path to success is focusing on security.

Is security a safe route for employment? I'm good at math and will probably pick up a mathematics minor along the way. What do you guys know about Security Jobs in Computer Science?

Could someone actually answer my questions? Mainly, what type of security work should I be looking into? What "Job Title"? Ethical Hacker or something else?
