Kube Bench
kube-bench is a Kubernetes security benchmark scanner and configuration auditor. It verifies if a cluster adheres to the Center for Internet Security standards and other hardening guides to identify security misconfigurations and vulnerabilities.
The tool operates as a containerized security scanner, utilizing host namespaces to analyze nodes and control plane components without requiring the installation of binaries directly on the host. It supports multiple Kubernetes distributions, applying environment-specific benchmarks to ensure auditing accuracy for managed services.
The project covers security auditing and compliance through the analysis of master nodes and node security. It includes capabilities for auditing against specific technical implementation guides and exporting security scan results in standardized formats for cloud security posture management.
Features
- Benchmark Scanning - Evaluates Kubernetes cluster configurations against industry-standard security benchmarks like the CIS Benchmark.
- Security Scanning - Analyzes Kubernetes cluster configurations and state to identify security risks and compliance violations.
- Policy Evaluation Engines - Implements a policy evaluation engine that compares actual cluster configurations against industry security standards.
- Security Benchmarking - Generates reports and verifies security gaps by benchmarking cluster configurations against professional standards and hardening guides.
- Container-Host Configuration Auditing - Utilizes host namespaces within containers to audit the security interface and configuration of the underlying host operating system.
- Cloud Compliance Auditors - Automates the evaluation of Kubernetes infrastructure against CIS regulatory frameworks and benchmarks.
- Kubernetes Configuration Auditing - Evaluates Kubernetes cluster settings and configurations for security flaws and compliance with established benchmarks.
- Misconfiguration Scanning - Evaluates cluster states and configuration files against security benchmarks to detect structural misconfigurations.
- Infrastructure Hardening - Inspects host-level settings and control plane configurations to secure the underlying node infrastructure.
- Host-to-Container Path Mappings - Mounts host directories into the container's filesystem to inspect sensitive system files and configuration settings.
- Distribution Profile Mapping - Maps specific benchmark sets to detected Kubernetes distributions to ensure auditing accuracy for managed services.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
