How to secure a Kubernetes cluster
Securing a Kubernetes cluster involves adopting a range of best practices that safeguard its various components from potential threats. A cluster’s security spans several layers, including the control plane, worker nodes, and the Kubernetes API. To help you understand how to implement these best practices effectively, we’ll break down the key areas that need your attention.
In the upcoming subsections, we’ll guide you through securing the control plane, which is the heart of the cluster’s operations; the worker nodes, where your applications and workloads run; and the Kubernetes API, which is part of the control plane and is the central interface for managing the cluster. By covering these critical areas, you’ll gain a comprehensive understanding of how to mitigate risks and enhance the overall security of your Kubernetes environment.
Here are some key security aspects to consider:
