This is the modern network security course built for working defenders — engineers, analysts, architects, and anyone serious about defending networks in the world we actually live in. The perimeter you grew up with is gone. Workloads moved to the cloud. Users work from anywhere. Modern attackers don’t break through the wall — they log in with stolen credentials, abuse trust between services, and live off the land. The defender’s job changed with them, and this course teaches the modern playbook end to end.
You will cover the foundations first — how networks actually work, where the historical security model came from, and why segmentation is the highest-leverage control in defense. Then you move through the disciplines: identity and access management, encryption, secure remote access, Zero Trust, and next-generation firewalls plus IDS/IPS in 2026.
Next you go into where modern work actually lives. SD-WAN architectures and the four major vendors. SASE and the convergence at the edge. Wireless, 5G, IoT, and operational technology. Cloud network security across AWS, Azure, and Google Cloud, including Kubernetes, APIs, and east-west traffic.
