This course teaches you how to strengthen your cluster’s underlying systems by reducing the host operating system’s attack surface. You’ll learn host hardening, how to remove unnecessary services, and set up logging and access controls. You'll cover network security, host firewalls, and kernel hardening with tools like SecComp and AppArmor. You’ll also focus on identity and access management, applying least privilege and understanding RBAC risks. Each lesson provides practical strategies to make your Kubernetes environments more secure and prepare you for the CKS exam.

In this module, you’ll learn strategies to strengthen the underlying systems that support Kubernetes. You’ll focus on minimizing the host operating system footprint, implementing pod security standards, reducing external network access, hardening the kernel, and optimizing identity and access management roles. By applying these techniques, you’ll build a resilient and secure Kubernetes infrastructure, making it much more difficult for attackers to compromise your system.
