The Center for Internet Security (CIS) creates best practices for cyber defense. The CIS uses crowdsourcing to define its security recommendations. The CIS Benchmarks are among its most popular tools
Organizations can use the CIS Benchmark for Kubernetes to harden their Kubernetes environments. A number of open source and commercial tools are available that automatically check against the settings and controls outlined in the CIS Benchmark to identify insecure configurations.
The CIS Benchmark provides a number of helpful configuration checks, but organizations should consider them a starting point and go beyond the CIS checks to ensure best practices are applied to Kubernetes, including implementing network policies, role-based access control (RBAC) settings, admin privileges, and other protections for the Kubernetes API server.
