The situation
Scenario. You are the security analyst for a small company. A new server (target) was put on the network and nobody is sure what it exposes. Your job: map it, list every open service, and flag anything that should not be there — before an attacker does.
What you will do
- Confirm you can reach the target
- Scan the common ports
- Record the open services
- Which service is the odd one out?question
- Flag the stray service
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.
