Minecraft Server Security & Backups

Server Security

Protect your server from attacks and data loss. Learn essential security practices and backup strategies to keep your Minecraft world safe.

  1. Firewall Configuration
    Use server firewall to restrict port access. Allow Minecraft port (usually 25565) only. Restrict panel access to known IPs. Block all other ports by default.
  2. Change Default Credentials
    Change admin password immediately. Use 20+ character passwords with mixed case/numbers/symbols. Never share credentials via unencrypted chat.
  3. Enable Whitelisting
    Use /whitelist on in server console to restrict access to invited players only. Add players with /whitelist add PlayerName.
  4. Ban System & Moderation
    Implement LiteBans or similar for banning rule-breakers. Track violations and appeals. Coordinate with moderators for consistent enforcement.
  5. Automated Backups (Critical)
    Enable Pterodactyl's automatic backup feature. Back up at least daily. Store backups in multiple locations (local + cloud). Test restore procedures monthly.
  6. Backup Rotation
    Keep 7 daily backups, 4 weekly, 12 monthly. Older backups automatically delete. This saves storage while maintaining recovery options.
  7. DDoS Protection
    Use a DDoS protection service (Cloudflare, OVH). Forward connections through protected IP layer. Cloudflare offers free DDoS mitigation.
  8. Plugin Security Audits
    Only install plugins from trusted sources (SpigotMC, Bukkit, CurseForge). Review plugin code for malicious activity. Keep plugins updated.
  9. PvP Protection Options
    Use /gamerule pvp false to disable PvP. Or use WorldGuard to create safe zones. Set spawn area as PvP-free via plugins.
  10. Disaster Recovery Plan
    Document restore procedures. Test backups work before disasters. Have geographically distributed backups. Keep offline backup copies.
