Comprehensive Home Game Hosting Security Guide
Security is the most overlooked aspect of game hosting. A single vulnerability in a plugin or an open port can lead to a full server compromise, data theft, or a devastating DDoS attack.
SSH Hardening
Changing default ports and using SSH keys instead of passwords for access.
Firewall Config
Using UFW or iptables to block all traffic except for necessary game ports.
Plugin Auditing
The importance of checking the source code of third-party mods before installation.
Backup Strategy
Implementing the 3-2-1 backup rule to ensure data is never permanently lost.
We emphasize the use of "containers" like Docker to isolate game servers from the main operating system. This ensures that if a game process is compromised, the attacker cannot easily gain access to the rest of the server's file system. Additionally, we recommend using automated security scanners to check for known vulnerabilities in your software stack.

Never run your game server as the 'root' user; always create a dedicated user with limited permissions.
