Welcome to the SSH Penetration Testing Repository, a dedicated resource for cybersecurity professionals, penetration testers, and experts in the field. This repository is tailored to provide in-depth insights and tools for assessing the security of SSH (Secure Shell) implementations across critical infrastructure, telecommunications, and corporate

Post-quantum SSH infrastructure toolkit built on OQS-OpenSSH. Deploy hybrid and quantum-resistant authentication with multi-algorithm support and automated key management — without modifying your system OpenSSH.

This project demonstrates SSH authentication log analysis using Splunk SIEM to detect malicious activity such as brute-force attacks, unauthorized access attempts, and suspicious SSH behavior. It simulates real-world SOC analyst workflows, including log ingestion, SPL queries, dashboards, and alerting.
