Chapter 6: Securing Cluster Components

In previous chapters, we looked at the architecture of a Kubernetes cluster. A Kubernetes cluster consists of master components—including kube-apiserver, etcd, kube-scheduler, CoreDNS, kube-controller-manager, and cloud-controller-manager—and node components, including kubelet, kube-proxy, and container-runtime. Master components are responsible for cluster management. They form the control plane of the cluster. Node components, on the other hand, are responsible for the functioning of pods and containers on the node.

In Chapter 3, Threat Modeling, we briefly discussed that components in a Kubernetes cluster need to be configured to ensure the security of the cluster. A compromise of any cluster component can cause a data breach. Misconfiguration of environments is one of the primary reasons for data breaches in traditional or microservices environments. It is important to understand the configurations for each component and...
