From Squire to Network Knight - Defending the Kubernetes Castle the Cloud Native Way

Learn to evolve from basic Kubernetes security practices to advanced cloud-native network protection in this 21-minute conference talk from CNCF. Start with a completely unprotected Kubernetes cluster and progressively build comprehensive security using cloud-native approaches rather than traditional perimeter-based methods. Discover the limitations of static, firewall-based security models and explore how to implement identity-based enforcement using Kubernetes Network Policies and Cilium's advanced capabilities including identity-aware protection, DNS enforcement, and rich observability features. Master debugging techniques for common network security issues while developing a mindset focused on intent-based security rather than infrastructure-dependent approaches. Gain practical skills to transition from traditional "firewall thinking" to modern cloud-native security paradigms, equipping yourself with both the technical tools and strategic perspective needed to effectively defend Kubernetes environments.
