Access Control and Permissions

Permission Structure

Implement a logical permission hierarchy:

# Basic player permissions
/lp group default permission set essentials.home
/lp group default permission set essentials.spawn

# Trusted players
/lp group trusted parent set default
/lp group trusted permission set worldedit.wand

# Staff members
/lp group staff parent set trusted
/lp group staff permission set essentials.ban

# Administrators
/lp group admin parent set staff
/lp group admin permission set "*"

Whitelist Management

Use whitelisting for private servers:

/whitelist on - Enable whitelist
/whitelist add PlayerName - Add player
/whitelist remove PlayerName - Remove player
/whitelist list - View whitelist

OP (Operator) Management

Limit OP access to essential staff only:

  • Only give OP to trusted administrators
  • Use permissions instead of OP when possible
  • Regularly review OP list
  • Document OP permissions

Grief Prevention

Claim-Based Protection

Implement claim systems for player protection:

  • Use GriefPrevention plugin for automatic claims
  • Set reasonable claim sizes
  • Implement claim expiration
  • Provide claim management tools

Spawn Protection

Protect critical areas with WorldGuard:

/region define spawn 50 50
/region flag spawn build deny
/region flag spawn pvp deny
/region flag spawn entry allow
/region flag spawn interact deny

Economy Protection

Secure player economies and shops:

  • Use ChestShop for secure trading
  • Implement transaction logging
  • Set up economy safeguards
  • Monitor for exploits

Network Security

DDoS Protection

Protect against distributed denial of service attacks:

  • Use hosting providers with DDoS protection
  • Implement rate limiting
  • Use reverse proxies
  • Monitor traffic patterns
  • Have backup IP addresses ready

Firewall Configuration

Secure your server's network access:

# Basic firewall rules
sudo ufw allow 25565/tcp - Minecraft port
sudo ufw allow ssh - SSH access
sudo ufw deny 25565/udp - Block UDP
sudo ufw enable

IP Whitelisting

For maximum security, implement IP whitelisting:

  • Restrict access to known IPs
  • Use VPN for staff access
  • Document allowed IPs
  • Regularly review access logs

Account Security

Authentication Plugins

Implement strong authentication measures:

  • Use AuthMeReloaded for offline mode servers
  • Implement two-factor authentication
  • Require strong passwords
  • Set session timeouts

Account Verification

Audit Trails

Maintain detailed audit records:

# Regular audit commands
/co purge t:30d - Clean old logs
/lp tree - Review permission structure
/whitelist list - Check whitelist status

Backup and Recovery

Automated Backups

Implement robust backup systems:

# Daily backup script
#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
tar -czf backup_$DATE.tar.gz world/
scp backup_$DATE.tar.gz backup@remote:/backups/
find /backups/ -name "*.tar.gz" -mtime +7 -delete

Recovery Procedures

Plan for security incidents:

  • Document recovery steps
  • Test backup restoration
  • Maintain offline backups
  • Have emergency contact procedures

World Corruption Protection

Prevent and detect world corruption:

  • Regular integrity checks
  • Region file monitoring
  • Corruption detection tools
  • Automatic rollback triggers

Community Management

Clear Rules and Enforcement

Establish and enforce server rules:

  • Post rules prominently
  • Implement warning systems
  • Use consistent punishment
  • Maintain appeal processes

Staff Training

Train staff on security procedures:

  • Security best practices
  • Incident response procedures
  • Player management techniques
  • Tool usage training

Player Reporting

Enable easy reporting systems:

  • Simple report commands
