I am going to college and have pretty much endless possiblities on what college i can go to so feel free to give any advice on what courses to take that could get me to be a professional at network security. I want to learn how to stop hackers and know all the different ways how to do it. I know a little but i want to learn a lot. Any ideas about books/online courses/college courses/specific colleges/online tutorials/ would be greatly appreciated.
