1. Install and Learn Linux
Linux is a hackable, and convenient operating system. The internals of it are
very interesting, and the foundation for a lot of engineering. But, they don't
concern you much right now. You just have to be able to navigate around in it,
install programs, and run programs. A virtual machine is easiest.
# Absolute basics ls - list directory contents cd [path] - change directory to [path] pwd - print working (current) directory man [command- pull up the manual for [command] cat [filename] - print [filename] contents mv [from_filename] [to_filename] - move a file cp [from_filename] [to_filename] - copy a file rm [filename] - remove a file nano [filename] - open a file for editting
2. Learn Python and C
My advice is to learn the syntax, and then go further in depth by actually programming with it. Some books are fairly decent too.
3. Learn some basics, and the landscape
There's a collection of great CTF videos here: https://www.youtube.com/channel/UClcE-kVhqyiHCcjYwcpfj9w/videos.
Each of them is ~5-10 minutes. Additionally, it's very interesting and useful to read write-ups of previous CTF challenges. They give you the mindset, and teach you the skills necessary, here's a basic set: https://ehsandev.com/pico2014/
4. Collect some tools
Security is a very tool oriented field. It's a good idea to know what tools are
out there, and make some of them part of your arsenal.
