Best Practices to secure Mikrotik routers.
This is a quick and simple post on how to get the most efficient and secure operation out of your Mikrotik router. If you follow these six principles, you will be on your way to a secure deployment.
- Stay Updated: Regularly update your MikroTik RouterOS to ensure you have the latest security features and bug fixes. You don’t have to run the latest code, but be aware of what changes. Sometimes you don’t need to upgrade unless you need features or a security vulnerability is being addressed in a newer version.
- Use Strong Passwords: Secure your MikroTik device with strong and unique passwords to prevent unauthorized access. If you are in a multi-user environment, consider using SSH keys and/or radius with a closely guarded local admin account.
- Practice the Principle of Least Privilege: Only grant the necessary permissions and access to users, limiting potential attack vectors.
- Regularly Audit Firewall Rules: Periodically review and update your firewall rules to align with your network’s evolving needs. Make sure you aren’t blocking too many things. Enterprise networks are different than Service Provider networks.
- Implement Logging and Monitoring: Configure logs and notifications to stay informed about firewall activities and potential threats.
- Secure Management Interfaces: Protect management interfaces like WebFig, Winbox, and SSH by limiting access to trusted IP addresses and management networks.
