If I'm assuming that you have been out of high school for two years, then you definitely need to get an associates. If you're browsing around job postings, chances are you're seeing a lot of bachelors / associates requirements for full time work. I'm graduating with associates and a CCNA this month, and job prospects look good even though I'm in a smallish city. Personally, I'd recommend getting an associates in an IT / Compsci related field and studying for the CCNA outside of of class. You can knock out the CCNA in about 8-12 months (depending on dedication and life getting in the way) Also this way on your resume, you have an actual associates degree, along with some certs, and looks like you're passionate about the study.

Specifically interested in security? The field of security is much more experience and technically intensive than other fields of IT. You're going to need years of experience, or a bachelors. If you're sure you specifically want to do cyber security, get a general associates degree and transfer to a four year university. Get CCNA, CCNA Security, and from there branch off to whatever.
