Hacking Kubernetes Cluster and Secure it with Open Source

Patrick Münch

People are under the impression that when you spin up the latest and greatest AKS, EKS, OpenShift or GKE instance, that you're secure. However with K8S, now more than ever the workload underneath matters. One privileged, neglected, container can compromise an entire setup. Rather than just talking about the risks or best practices, this talk is all about showing how easy it is to do.
The talk will first discuss possible attack paths in the Kubernetes cluster, and what differences exist in the attack techniques compared to classic infrastructures. For this purpose, a web application in a container will be compromised, then the Kubernetes cluster and the cloud account. Subsequently, 2 open-source tools will be discussed how such vulnerabilities and misconfigurations can be detected in the different infrastructure layers.
