ssh-audit is a command-line tool designed for auditing SSH server and client configurations to assess their security posture. The tool supports analysis of both SSH1 and SSH2 protocol implementations, providing comprehensive evaluation capabilities for SSH infrastructure. Key features include: - SSH server configuration analysis and security assessment - SSH client configuration evaluation - Banner grabbing and device/software recognition capabilities - Compression detection and algorithm analysis - Security information output with detailed findings - Version compatibility analysis across different SSH implementations - Historical information retrieval for tracking configuration changes - Policy-based scanning with customizable security policies - Cross-platform compatibility supporting Linux and Windows environments The tool operates through Python 3.8 - 3.12 and provides detailed reports on SSH configuration weaknesses, algorithm strengths, and compliance with security best practices. It can identify deprecated algorithms, weak encryption methods, and configuration issues that may expose SSH services to security risks.
