security roadmap
A junior defensive-leaning path. You will learn the command line, how networks work, how web apps fail (in legal labs only), cryptography hygiene, and how to behave under an incident. Unauthorized access is out of scope — forever.
Stages run top to bottom; skills inside a stage can be taken in any order unless a line says otherwise. Locked nodes need their required predecessor first.
Scope and law first, then the defensive baseline, the shell and the wire.
Scripting, version control and the web vulnerability classes.
Crypto hygiene and authorised reconnaissance in legal labs.
Assess and harden a lab system end to end.
Behave well on the worst day: incident response basics.
