Sinopse:
Kubernetes clusters are powerful, but they become fragile fast when control plane access, Pod permissions, and network boundaries are left loose. The table of contents makes the threat surface unmistakable: it moves from Pod security into network separation, then control plane hardening, authentication and authorization, and finally audit logging and threat detection, which is exactly the operational path a hardened cluster needs. This report is structured like a practical security checklist, not a conceptual primer. It walks through non-root containers, immutable file systems, secure image builds, Pod security enforcement, service account token protection, namespace and network policy design, etcd and kubeconfig protection, RBAC, logging pipelines, seccomp audit mode, and alerting. The authorship is institutional rather than individual, produced by NSA and CISA for administrators and developers responsible for real deployments. The result is a compact hardening playbook for teams running Kubernetes in sensitive environments. Readers get a clear sequence of controls that reduce breakout risk, limit blast radius, improve visibility, and make misconfigurations easier to catch before they become incidents. It is especially useful for infrastructure teams that need authoritative guidance on securing clusters without losing sight of day-to-day operations.
