What jobs in the Air Force correlate into getting a job with the FBI, NSA or CIA?

Hello i am a 22 year old female who will be graduating from college with a degree in Advertising and Communication Technology within a year. I will be enlisting into the Air Force as soon as i get my college diploma. I am wanting to serve my country to the best of my ability while putting aside my own wants and needs to serve the greater good of things which in itself makes me VERY happy. All the men on my fathers side of the family have been in the Air Force my uncles were pilots and navigators my father while he went into the Navy was a Yeoman. In no way have i been pressured into this decision i am wanting to do this for of course the travel and because i just want to do my part in making the world a better place.
