Description: Kubernetes cluster security refers to the practice of securing all components of a Kubernetes cluster, including nodes, workloads, and the communication between them. This approach is fundamental in a cloud computing environment, where applications are deployed in containers and managed dynamically. Security in Kubernetes involves implementing access policies, authentication, and authorization, as well as protecting data in transit and at rest. A ‘Zero Trust’ approach is essential, where it is assumed that no entity, whether internal or external, is trusted by default. This means that every access request must be verified and authenticated, regardless of its origin. Key features of cluster security include network segmentation, the use of pod security policies, secret management, and event auditing. The relevance of this security lies in the growing adoption of Kubernetes for container orchestration, making it an attractive target for attackers. Protecting a Kubernetes cluster not only helps safeguard data and applications but also ensures the integrity and availability of the services that rely on this infrastructure.
