This Kubernetes security checklist presents an eight-step framework for protecting cloud-native environments where containers are short-lived and attacks can unfold in minutes. It explains key risk areas across applications, third-party libraries, the control plane, nodes, and workloads, then emphasizes securing infrastructure as code, enforcing policies with admission controllers, and hardening the Kubernetes control plane. The checklist highlights runtime security to detect abnormal behavior, continuous vulnerability scanning, network segmentation using Kubernetes-native policies, and automated incident response with full forensic capture. It also contrasts DIY open source approaches with turnkey platforms, arguing that automation, runtime visibility, and integrated controls are essentia
