Stage 01
Build the base
Become comfortable with Linux, networking, HTTP, Git, and the way security notes are written.
- Use Linux daily and learn the shell commands you actually need for recon, files, processes, and services.
- Review TCP/IP, DNS, HTTP, TLS, routing, and common service ports until packet captures feel readable.
- Keep short notes for every concept: what it is, how to test it, and one command or tool that proves it.
