Cybrary is a good place to get your foot on the ground. It allows you to learn the basics of networking and InfoSec. Keep in mind that if you want to become a hacker (blackhat, whitehat or else), you need to be proficient at using several types of operating systems (linux, windows, macos, etc), be wary of how internet and communications work (routing, switching, ospf, bgp, tcp/ip, osi, etc), be able to use one or more programming languages (python and c are good places to start, js might also be handy) and be a fast learner (because the IT keeps growing fast and you need to be able to learn as It grows).
