kube-bench is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the CIS Kubernetes Benchmark.
Tests are configured with YAML files, making this tool easy to update as test specifications evolve.
kube-bench implements the CIS Kubernetes Benchmark as closely as possible. Please raise issues here if kube-bench is not correctly implementing the test as described in the Benchmark. To report issues in the Benchmark itself (for example, tests that you believe are inappropriate), please join the CIS community.
There is not a one-to-one mapping between releases of Kubernetes and releases of the CIS benchmark. See CIS Kubernetes Benchmark support to see which releases of Kubernetes are covered by different releases of the benchmark.
