Kubernetes Security Checklist for Cloud Applications

This document is a checklist designed to enhance security measures for Kubernetes environments. It outlines five essential steps to secure Kubernetes, emphasizing the importance of addressing security risks early in the deployment process. The checklist begins by detailing the various components of a Kubernetes cluster that require protection, including applications, libraries, and the control plane. It explains the significance of Infrastructure as Code (IaC) in managing security configurations and automating compliance. The document further discusses the role of admission controllers in preventing the deployment of insecure images and highlights the necessity of securing the Kubernetes control plane to prevent unauthorized access. Additionally, it addresses runtime security measures to detect abnormal behaviors in containers, ensuring that security protocols are maintained throughout the lifecycle of cloud-native applications. This resource serves as a comprehensive guide for DevOps teams aiming to implement effective security strategies in their Kubernetes deployments.
