drydock is a Docker security audit tool written in Python that performs security assessments of Docker environments. The tool enables users to create and utilize custom audit profiles to reduce noise and eliminate false alarms during security evaluations. It generates reports in JSON format to facilitate easier parsing and analysis of audit results. drydock is built upon the CIS Docker 1.6 Benchmark standards and leverages the docker-py client API for communication with Docker environments. The tool allows security professionals to conduct systematic security audits of Docker configurations and deployments. Users can either utilize provided audit profiles or develop custom profiles tailored to their specific security requirements and organizational needs.
