kube-bench
by aquasecurity
kube-bench is a compliance auditing tool that checks Kubernetes deployments against the CIS Kubernetes Benchmark to ensure secure configurations.
Checks whether Kubernetes is deployed according to security best practices as defined in the CIS Kubernetes Benchmark
Primary Use Case
kube-bench is used by Kubernetes administrators and security professionals to verify that their Kubernetes clusters adhere to established security best practices defined by the CIS Kubernetes Benchmark. It helps automate security compliance checks and identify misconfigurations in Kubernetes deployments, facilitating continuous security auditing and hardening.
- Implements CIS Kubernetes Benchmark security checks
- Configurable tests via YAML files for easy updates
- Supports running as a Kubernetes job or inside a pod
- Integrates with Trivy and Trivy Operator for extended scanning
- Outputs detailed logs of compliance results
- Automatically detects Kubernetes version to select appropriate tests
Installation
- Apply the supplied Kubernetes job manifest: kubectl apply -f job.yaml
- Wait for the kube-bench job pod to complete
- Retrieve results from the pod logs using: kubectl logs <pod-name>
Usage
>_ kubectl apply -f job.yamlDeploys kube-bench as a Kubernetes job to run CIS benchmark checks.
>_ kubectl get podsLists pods to monitor the status of the kube-bench job.
>_ kubectl logs <pod-name>Displays the output logs of the kube-bench job containing compliance results.
- Integrate kube-bench scans into CI/CD pipelines for continuous compliance auditing.
- Combine kube-bench with runtime security tools like Trivy Operator for comprehensive Kubernetes security posture management.
- Use kube-bench results to prioritize remediation efforts and harden Kubernetes clusters against common misconfigurations.
- Automate alerting on compliance failures to enable rapid response by security operations teams.
- Leverage kube-bench’s YAML-configurable tests to customize benchmarks for organization-specific Kubernetes security policies.
