Game servers need specific ports open and everything else shut. Configure UFW to expose only your game's ports, protect RCON, and cut attack surface.

Working as root all the time is dangerous. Create a dedicated sudo user, give it your SSH key, and adopt least-privilege as your default way of working.

Even hardened servers get probed. Learn to scan for rootkits and malware with rkhunter and ClamAV, read the results, and respond to a real detection.
