Network & Security: Diagnose, Troubleshoot, and Secure Real Environments
Networks fail, and attackers look for the same weaknesses that cause those failures. In this hands-on session, you will learn how to diagnose common network problems step by step; IP addressing, DNS, routing, ports, firewalls, and services all while understanding the security risks behind each layer. You will see how a small misconfiguration can break connectivity or expose a system, and how to fix it with a clear, calm, and security-focused method.
