Securing MikroTik RouterOS With Proxy Server Blacklisting Techniques

Have you ever wondered how to secure your MikroTik RouterOS? Well, you're in luck! We've compiled a list of hardening techniques that can help you secure your RouterOS.

What is RouterOS?

RouterOS is a Linux-based operating system that is used by MikroTik routers. It offers a range of features including routing, firewall, bandwidth management, wireless access point, backhaul link, hotspot gateway, and VPN server.

Why Security is Important

Security is key when it comes to RouterOS. In today's world, where cyber attacks are becoming increasingly common, it is important to take steps to secure your router. A compromised router can be used to launch further attacks, steal sensitive information, or monitor internet traffic.

Hardening Techniques

Now that we understand why security is important, let's take a look at some techniques that can help harden your RouterOS.

1. Change Default Login Credentials

One of the first things you should do when setting up your RouterOS is changing the default login credentials. The default username is "admin" and the default password is blank. Leaving the default credentials in place is a security risk as it makes it easy for attackers to gain access to your router. Choose a strong password that includes a combination of uppercase and lowercase letters, numbers, and special characters.

2. Disable Unnecessary Services

By default, RouterOS runs several services including FTP, SSH, and Telnet. However, if you're not using these services, it is best to disable them as they can be used by attackers to gain access to your router. You can disable services by navigating to IP → Services and unchecking the services you don't need.

3. Update RouterOS

Regularly updating your RouterOS is essential as it provides security fixes and new features. You can check for the latest updates by navigating to System → Packages and clicking on Check For Updates.

4. Enable Firewall

Enabling the firewall is another key step in securing your RouterOS. The firewall can be used to block unwanted traffic and protect your router from attack. You can enable the firewall by navigating to IP → Firewall and creating a new firewall rule.

5. Limit Access to the Router

Limiting access to the router is another important step in securing it. You can limit access by configuring the IP address of devices that are allowed to connect to the router. You can do this by navigating to IP → Services and editing the services you want to limit access to.

6. Use Strong Encryption

Using strong encryption is essential when it comes to securing your router. You should use WPA2 encryption for wireless access points and strong encryption algorithms for VPN connections.

7. Disable Remote Access

Remote access to your router is another security risk. By default, RouterOS allows remote access via the Webfig, Winbox, and SSH services. However, it is best to disable remote access unless you require it for management purposes. You can disable remote access by navigating to IP → Services and unchecking the relevant services.

8. Limit Bandwidth

Limiting bandwidth is another key step in securing your RouterOS. By limiting bandwidth, you can prevent attackers from using your router for malicious purposes. You can limit bandwidth by navigating to Queues and creating a new queue.
