ssh_scan analyzes SSH server configurations to assess compliance with security policies. The tool examines various settings—ciphers, MACs, and key exchange algorithms—against a customizable policy. It provides a JSON report detailing the server's configuration and whether it adheres to the defined policy, ultimately helping to identify potential security weaknesses.
ssh_scan offers a minimal dependency footprint, relying on native Ruby and BinData. Its portable implementation allows integration into other projects or automation workflows. It provides a simple, configurable tool for SSH policy validation, with example policies available for customization. The project's focus is on command-line usage, with an API project available for service integration.
