Running a Minecraft server comes with security challenges. From DDoS attacks to griefing, server owners need to be prepared. This guide covers essential security measures to protect your server and community.

DDoS Protection
Distributed Denial of Service (DDoS) attacks can take your server offline:
- Use a Proxy: Services like TCPShield or Cloudflare hide your real IP
- DDoS-Protected Hosting: Choose a host with built-in protection
- Never Share Your IP: Only share the proxy address publicly
- Monitor Traffic: Watch for unusual traffic patterns
Warning
Never reveal your server's real IP address in console logs, Discord, or to untrusted players!
Preventing Exploits
Keep your server safe from common exploits:
- Update Regularly: Always run the latest server software version
- Patch Plugins: Outdated plugins are the #1 vulnerability
- Disable Unused Features: Turn off command blocks if not needed
- Limit NBT Data: Prevent crash items and lag machines
Essential Security Plugins
Recommended Security Plugins
AntiCheat: Vulcan, Grim, or Matrix
Anti-Bot: BotSentry, AntiBot
Protection: WorldGuard, CoreProtect
Auth: AuthMe, Login Security
Firewall: IPWhitelist, GeoIP
Proper Permission Setup
Bad permissions lead to disasters:
- Use LuckPerms or similar for granular control
- Never give
*permission to anyone except console - Test new ranks in a separate test server
- Regularly audit staff permissions
- Use permission inheritance properly
Backup Strategy
When all else fails, backups save the day:
- Automated Backups: Every 6-12 hours minimum
- Off-site Storage: Keep backups on separate storage
- Test Restores: Regularly verify backups work
- Version Control: Keep multiple backup versions
Pro Tip
Use CoreProtect to log all block changes. You can roll back griefing without restoring a full backup!
