Learn to harden Kubernetes node operating systems by minimizing attack surfaces, restricting access, and applying security best practices.
45 minutes
kubernetes-security/cks
Lab Overview
This hands-on lab teaches you to secure the underlying host operating system of Kubernetes nodes for CKS exam preparation.
You'll learn to:
- Minimize the host attack surface by removing unnecessary packages
- Restrict direct node access and implement SSH hardening
- Control kernel module loading for enhanced security
- Apply security updates and manage system hardening
Host OS hardening is a foundational security practice for Kubernetes clusters, reducing the risk of node-level compromises that could affect the entire cluster.
