Game Server Security

The 10 Most Important Security Measures

1. Strong Passwords

❌ admin123
❌ password
✅ Kf8#mP2$xQ9!nL4w (random, 16+ characters)

2. Change Your RCON Password

Change the default RCON password immediately after setup. RCON gives full server access!

3. Configure Firewall

Only open the ports you need:

What Port Protocol
Game Game-dependent TCP/UDP
RCON Game-dependent TCP
SSH 22 TCP
SFTP 2022 TCP

4. Keep Software Up to Date

  • Update server software regularly
  • Keep plugins/mods current
  • Apply operating system updates

5. Create Backups

  • Automatic daily backups
  • Manual backup before every major update
  • Store backups in a separate location

6. Limit Admin Privileges

Only grant admin access to trusted people. Use tiered permission levels.

7. Enable Anti-Cheat

  • VAC (CS2, TF2)
  • BattlEye (ARK, Rust)
  • EasyAntiCheat (various games)
  • Server-side anti-cheat plugins

8. Protect Your Server IP

Use a domain instead of the raw IP address. In case of a DDoS attack, switching IPs is much easier.

9. Enable Logging

Log all important events:

  • Player joins/leaves
  • Admin actions
  • Errors and crashes

10. Regular Review

  • Review logs monthly
  • Remove unknown admins
  • Audit your plugins
