Security Best Practices for RabbitMQ in Production

Role-Based Access Control (RBAC)

• Each user should only have access to what they need.
• Assign permissions at the vhost level.
• Avoid giving full access to all apps.

Example:

• app_user: can only publish/consume in /app_vhost.
• admin_user: can manage queues, exchanges.

Network Security

• Do not expose RabbitMQ directly to the internet.
• Place RabbitMQ behind a firewall or load balancer.
• Open only needed ports:
  • 5672 (AMQP) / 5671 (AMQP over TLS)
  • 15672 (management UI, protect with TLS + auth)
• Block all others.

Limit Management Access

• The management plugin is powerful but risky.
• Restrict access to trusted IP ranges or internal VPN.
• Create separate accounts:
  • Monitoring account (read-only).
  • Admin account (full rights).

Enable Logging and Monitoring

• Enable audit logging to track who connects and what actions they take.
• Forward logs to a central system (ELK, Grafana, Prometheus).
• Monitor unusual activities:
  • Many failed login attempts.
  • Sudden spikes in connections.

Keep RabbitMQ Updated

• Always use the latest stable RabbitMQ and Erlang versions.
• Security patches are released often.
• Use automation (Ansible, Docker, Kubernetes) to keep versions consistent.

Use Quorum Queues for Reliability

• For secure and reliable storage, prefer quorum queues.
• Messages are replicated: less chance of loss if a node is compromised.

Regular Security Reviews

• Perform penetration testing.
• Rotate user credentials.
• Review firewall and load balancer rules.
• Remove unused users, vhosts, and queues.

• All traffic uses TLS.
• Admins connect via VPN.
• Logs are shipped to monitoring.

Conclusion

Securing RabbitMQ in production is about defense in depth:

• Encrypt traffic with TLS.
• Use strong auth and role-based permissions.
• Protect with firewalls and VPNs.
• Monitor activity and keep RabbitMQ updated.

With these practices, RabbitMQ will stay secure, reliable, and production-ready.
