Network Security Fundamentals
Build a strong foundation in network protocols, firewall configuration, intrusion detection, and security monitoring for enterprise environments.
Network Security Fundamentals builds the foundation every security professional needs. Across 32 hours you learn how networks work, how they are attacked, and how to defend them — from the packet up. It is the ideal first step into security, and a thorough refresher for anyone whose networking knowledge has gone rusty.
Who this course is for
It suits IT professionals moving into security, help-desk and systems staff broadening their skills, and newcomers who want a rigorous grounding before specialising. No prior security experience is required.
What you will be able to do
You will understand core protocols and how attackers abuse them, configure firewalls with rule sets that fail safe, deploy and tune intrusion detection and prevention systems, and stand up the monitoring that lets a team see an attack while it is happening. You will also learn to reduce attack surface through hardening and network segmentation.
How it is taught
The emphasis throughout is practical. Rather than memorising definitions, you configure, attack, and defend real network setups in the lab, so the concepts stick and transfer directly to the workplace. Each topic pairs a clear explanation with hands-on exercises.
By the end you will have the confident, foundational understanding that every more advanced security discipline — penetration testing, cloud security, incident response — builds upon.
