Network outages and security breaches often stem from the same root cause: poorly understood configuration and missing monitoring. In this course, Networking and Firewall Configuration in Ubuntu Linux, you'll gain the ability to set up, diagnose, and defend your systems' network layer with confidence. First, you'll explore how to configure static IP addresses, manage interfaces, and resolve DNS using modern Ubuntu tools such as Netplan and systemd-resolved. Next, you'll discover how to diagnose connectivity failures by testing reachability, inspecting sockets, and capturing packets to trace problems to their source. Finally, you'll learn how to apply layered firewall rules using UFW to allow legitimate traffic while blocking threats and limiting brute-force attacks. When you're finished with this course, you'll have the skills and knowledge of Ubuntu network administration and security controls needed to maintain connectivity and protect your infrastructure.
