CISA and NSA Release Kubernetes Hardening Guidance

The National Security Agency (NSA) and CISA have released Kubernetes Hardening Guidance, a cybersecurity technical report detailing the complexities of securely managing Kubernetes—an open-source, container-orchestration system used to automate deploying, scaling, and managing containerized applications.

This report describes the security challenges associated with setting up and securing a Kubernetes cluster, and presents hardening strategies to guide system administrators in avoiding common misconfigurations.

CISA encourages users and administrators to ensure the security of applications by following the hardening guidance outlined in this report.
