What you'll learn

Kubernetes clusters often run with insecure defaults, leaving control plane components, worker nodes, and access controls exposed to potential compromise. In this course, Kubernetes System Hardening, you’ll gain the ability to secure clusters at the system level following CIS Benchmark–aligned best practices. First, you’ll explore how to harden control plane components and protect critical configuration files and credentials. Next, you’ll discover strategies to fortify worker nodes, secure the Kubelet, and restrict node-level access. Finally, you’ll learn how to implement least-privilege RBAC and manage Service Account permissions safely. When you’re finished with this course, you’ll have the skills and knowledge of Kubernetes system hardening needed to operate clusters securely and confidently in production environments.
