I created a practical Linux Security Hardening Guide focused on securing Linux servers and reducing common security risks. The work covers system hardening, user and access control, SSH security, firewall configuration, logging and monitoring, incident response, and security best practices. It provides structured steps, practical commands, checklists, and real-world examples that system administrators and IT professionals can use to strengthen Linux environments and maintain secure server configurations
