The situation
Phase 2 — Scanning. Recon is done. Now map target properly: which ports are open, which are filtered by a firewall, and what the scan timing tells you.
What you will do

- Record the reachable services
How it works
The lab opens in your browser: a real terminal or desktop, nothing to install. Work through the tasks, press Check after each one and the portal verifies your work. Stuck? Ask for a hint. Finish every task and you get a certificate page with its own verification link for LinkedIn or your CV.
