The situation
Scenario. Recon told you which ports are open on target. Now the incident-response lead needs to know what is listening and which version, so they can check it against known-vulnerable releases. You will fingerprint the services the way both attackers and defenders do.
What you will do
- Version-scan the services
- Grab the web banner by hand
- Name the web server
- Why does the full Server banner matter?question
- Reduce the banner on the target
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.
