Kubernetes Control Plane: 10 Tips for Airtight K8s Security

A recent report revealed that 94% of respondents experienced Kubernetes-related security incidents. Misconfigurations are the most common vulnerability, affecting 70% of surveyed companies. To secure the Kubernetes control plane and speed up deployment, teams should follow these best practices: use Role-Based Access Control (RBAC), isolate nodes and traffic, avoid deploying objects to the default namespace, encrypt secrets, secure access to etcd, don't mount container runtime sockets in containers, run containers with a read-only root file system, secure control plane access, create a rolling update strategy, and scan for vulnerabilities at runtime.
