For those looking to gain understanding and validate your progress as your begin the journey to Info Sec, I would encourage taking CompTIA’s Network+ and Security+. CompTIA provides vendor neutral exams that will test your knowledge in various ways. I mentioned both exams because there are principles of both exam present on each. Meaning you may see some security principles on the Network+ exam and vice versa. You can take the Security+ exam only but it would be beneficial to study for the Network+ as well for a more well rounded approach.

There are well written guides available on Amazon and other book stores that can be used for study material. If your skilled at navigating Youtube University, I’ve heard there is a lot of information there. Check out Cybrary as well for IT related study material.
