Kubernetes Security: Securing the Container Supply Chain for CKS

Securing a Kubernetes cluster goes far beyond runtime defenses; it starts at the very beginning of the software supply chain. As containerized deployments scale, ensuring that only trusted, scanned, and verified code runs in your environment is critical for preventing modern security breaches. This text-only course guides you through the foundational concepts of Kubernetes supply chain security, aligning with key objectives of the Certified Kubernetes Security Specialist (CKS) domain. You will gain a clear understanding of how to audit container images, verify signatures, and mitigate risks before code ever reaches your production cluster. What you'll learn: - Understand the core components and potential vulnerabilities of the container software supply chain - Analyze container images and Kubernetes manifests for security flaws using static analysis tools - Configure secure container registries and manage image pull secrets effectively - Apply digital signatures to container images and verify them inside your cluster using modern tools - Minimize container attack surfaces by utilizing minimal base images and secure build practices - Implement admission controllers to enforce image security policies at deployment time The course begins with essential security terminology and foundational concepts before moving into practical configuration guides and written step-by-step security scenarios. You will read through clear explanations, analyze configuration snippets, and complete written exercises to reinforce your learning. This course is designed for system administrators, DevOps engineers, and aspiring security specialists who are new to Kubernetes supply chain security and want to build strong, foundational knowledge. No advanced security background is required. Start reading today to secure your deployments from the ground up.
