![]() It serves as the main interface for cluster communications, since it is the only cluster component that all control plane and worker components can communicate with directly.Ī number of vulnerabilities impacting the Kubernetes API server have been and continue to be disclosed. This is the central control plane component that exposes the Kubernetes API and receives and validates application programming interface (API) requests for resource creation and modification. The Kubernetes control plane includes the components listed below, along with recommended steps you can take to increase security for each component. Therefore, a critical starting point for any effort to secure Kubernetes is to initially focus on protecting its control plane services. Also, to achieve high availability and resiliency-especially for production cluster environments-both sets of components can be deployed across multiple machines that form a cluster.Ĭonsidering that the Kubernetes control plane is designed to make global decisions regarding a cluster’s operations, compromise of control plane components could easily result in complete compromise of a cluster. ![]() The cluster’s worker nodes, which run containerized applications in pods. The control plane, which is used to manage operations throughout the cluster, and In order to know how to more effectively secure your Kubernetes environments, it is important to understand the architecture of Kubernetes itself as well as where and how to focus efforts on valuable mitigations.Įach Kubernetes cluster consists of two sets of components: ![]() ![]() Kubernetes is a robust yet complex infrastructure system for container orchestration, with multiple components that must be adequately protected. ![]()
