Today, the National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) issued the “Kubernetes Hardening Guidance” Cybersecurity Technical Report. This study examines risks to Kubernetes settings and offers recommendations for reducing risk.
Kubernetes is an open source platform for automating the deployment, scaling, and administration of containerized applications. Kubernetes clusters are frequently hosted in the cloud and offer more flexibility than traditional software platforms.
The study includes ideas for improving the security of Kubernetes systems. Scanning containers and Pods for vulnerabilities and misconfigurations, operating containers and Pods with the fewest rights feasible, and utilising network isolation, firewalls, strong authentication, and log audits are among the most important tasks.
To maintain application security, system administrators should follow the recommendations in the Cybersecurity Technical Report and stay current with patches, updates, and upgrades. Periodic evaluations of Kubernetes settings and vulnerability scans are also recommended by the NSA and CISA to verify that relevant risks are accounted for and security fixes are deployed.
The advise from the NSA and CISA focuses on security issues and suggests that system administrators harden their environments when possible. As part of our responsibility to support the Department of Defense, the Defense Industrial Base, and National Security Systems, the NSA is issuing this guidance.
