I would suggest looking into the Air Force; they other branches of the armed forces (I'm pretty sure) all have divisions devoted to counter-cyberterrorism of some kind but I think the Air Force has their Cyber Command...I saw something on tv about it:
http://www.afcyber.af.mil/I agree that you should go for the B.S. in Computer Science. Some technical oriented universities like ITT Tech and Devry have Information Systems Security programs that could be worth looking into; I wouldn't know for sure.
The NSA, DIA, CIA, and probably FBI would be good places to look, I think.
Hope this helps!
