How To Secure A Linux Server is a practical, evolving guide for hardening Linux servers in personal, hobby, and small-scale production environments. It focuses on step-by-step security improvements rather than abstract theory, making it accessible to administrators who need clear actions. The guide covers server setup, operating system choices, SSH hardening, firewall rules, user accounts, automatic updates, logging, intrusion prevention, and common web server considerations. It also includes dedicated material for kernel sysctl hardening and Nginx security. The project is not positioned as a complete enterprise compliance framework, but it provides a strong baseline for safer self-hosted servers. It is especially useful for developers, homelab users, and small teams who manage internet-facing Linux machines and want a checklist-style security reference.
