What kube-bench does

kube-bench runs the checks of the CIS Kubernetes Benchmark against a node: file permissions, API server flags, kubelet configuration and so on. Checks are defined in YAML so they can follow new benchmark versions and managed distributions such as EKS, GKE and AKS.

It is usually run as a Kubernetes Job on each node type and reports pass, fail and warning results with remediation text.

Key features

  • CIS Kubernetes Benchmark checks
  • Profiles for managed distributions
  • YAML-defined tests
  • Runs as a Job or a binary on the node
  • JSON and JUnit output
