I'm currently working my first job in IT, for two years now, after having only fast food and retail jobs. How did I get here? It wasn't my college education (I'm a dropout, due to transportation and money issues at the time). College did play a big role, though.
One of my instructors saw that talent you mentioned in me, and she knew I was into Linux while the rest of the students knew only Windows. One day one of her old students called her up and asked if she knew anyone who might be a good fit for a job he was trying to fill. I was the guy she went to, and now I'm in IT.
Long story short, it might be beneficial to you to know people who know people in IT security. College may be the place to meet those connections, though there are many other ways and places to accomplish that.
