-kube-bench is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the [CIS Kubernetes Benchmark](https://www.cisecurity.org/benchmark/kubernetes/). Note that it is impossible to inspect master nodes of managed clusters, e.g. GKE, EKS and AKS, using kube-bench as one does not have access to such nodes.

 Tests are configured with YAML files, making this tool easy to update as test specifications evolve.
