Docker Bench for Security is an open-source script that performs automated security assessments of Docker container deployments in production environments. The tool conducts comprehensive checks against dozens of common security best practices for Docker containers and hosts. It implements automated tests based on the CIS Docker Benchmark v1.6.0, providing standardized security evaluation criteria. The script evaluates various aspects of Docker security configuration including container runtime settings, host system configurations, Docker daemon settings, and network security parameters. It identifies potential security misconfigurations and provides recommendations aligned with industry best practices. Docker Bench for Security generates detailed reports highlighting security issues and compliance gaps, enabling organizations to assess their Docker security posture systematically. The tool supports self-assessment capabilities for Docker community members and security professionals managing containerized environments.
