The Kubernetes Hardening Guidance Report, produced by the National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA), provides guidance for cluster administrators to minimize risks in their Kubernetes environments. The report details critical threats to Kubernetes security and offers hardening techniques for three key areas: container and pod scanning, running containers with restrictive privileges, and network security recommendations. By following these guidelines, cluster administrators can improve the overall security posture of their Kubernetes clusters.
