Securing production with network polices - What can possible go wrong? - Simon Pearce

This talk covers the importance of network policies as a crucial security layer in defining access policies for communication between pods in Kubernetes. The speaker discusses how and why to implement network policies, providing an overview of available options to secure pod network traffic. Attendees will learn about regular network policies, cluster-wide policies, and host policies, with a demonstration focused on applying these policies to a running cluster. The session includes insights into using Cilium and Hubble to visualize cluster traffic, helping demystify network policies and offering valuable arguments for securing production clusters. Simon Pearce, a Kubernetes and Cloud consultant at SysEleven, draws on his experience with MetaKube, their managed Kubernetes platform hosting over 300 clusters.
