I had a decent conversation with a security expert (DoD, airforce, SANS, etc.) over lunch a few years ago. We talked about the need for security professionals and how hard it was finding them. If I recall, he mentioned a program out of Baltimore college/university. High school students were being identified, sent to college, given internships, etc. to build up the population. I wish I had more details, but I am certain programs are out there.
Any student going down that path should not need to pay for college. Our industry is regularly credited with a negative unemplyment rate. People are needed and demand a premium.
As far as maintaining interest and gaining more insight, following industry experts like Kevin Mandia, Krebs, Ulevitch, and even Kaspersky to name a few. Also blogs like malware.dontneedcoffee has some intersting stuff.
Finally, remember that people will try to push for certifications for networking stuff. This won't be a popular comment, but networking is not cybersecurity. Its a very important piece, but those focus on setting up rules and such, not hunting down and uderstanding malware, the bad guys, and their techiques. That is cybersecurity.
