There are many facets to security in Kubernetes. One small oversight can leave your cluster vulnerable to leaking sensitive data, running foreign workloads, and a host of other attacks. This lab shows you how to practice defense in depth in Kubernetes by covering a key security concept: security contexts. Examples of potential exploits from improperly configured clusters are also illustrated followed by guidance on how to prevent the attacks.
