Do you like to learn new skills in cyber security? Do you enjoy learning on your own through books, videos, and online resources? I am very often looking to find the next topic or skillset to spend time on exploring, and over the years I have found a few websites that I could repeatedly rely on for a wide variety of free academics. I have compiled them below along with some bullet-points on why each may be of value to you as they have been to me.

Happy learning!
