Avoiding it as such is not possible, however, if it is possible to deny connections from this cloned MAC, the access List option in the wireless section allows you to establish rules to mitigate this type of connections. One of these options can be Management Protection Key, which is an additional key. private that only the original computer should have, so when the computer that uses the cloned MAC tries to connect it will not be possible since only the original computer will have the key.
MAC (Media Access Control) cloning is a technique used to copy the MAC address of an authorized device to another device, allowing the unauthorized device to access the network as if it were the authorized device.
We mention other strategies to avoid MAC cloning on your MikroTik network:
1. Use Advanced MAC Filtering:
MikroTik allows you to implement MAC filtering so that only devices with specific MAC addresses can connect. However, this may not be enough on its own, as MAC addresses can be cloned. You can improve security by combining MAC filtering with other security measures.
2. Enable WPA2/WPA3 Authentication:
Using robust security protocols such as WPA2 or WPA3 for the WiFi network significantly increases the difficulty of unauthorized access. Although an attacker can clone a MAC address, without the network password, access will not be possible.
3. Implement 802.1X Authentication:
802.1X authentication provides portal-based access control for LAN and WLAN networks. This method uses a RADIUS server to authenticate each user or device individually, meaning that even if an attacker clones a MAC address, they would still need to go through the authentication process to access the network.
4. Limit the Number of Devices per MAC Address:
Configure your MikroTik network to limit the number of devices that can connect with the same MAC address. This may discourage the use of cloned MAC addresses, as an excessive number of connections with the same MAC will raise alerts and could automatically block access.
5. Network Monitoring and Alerts:
Establish a monitoring system that alerts you to unusual behavior, such as multiple devices trying to connect with the same MAC address. This will allow you to react quickly to possible MAC cloning attempts.
6. Firmware and Software Updates:
Keep your MikroTik hardware and any related software up to date to ensure you are protected against the latest vulnerabilities and attack techniques, including MAC cloning.
7. Education and Acceptable Use Policies:
Educating users on your network about acceptable use policies and good security practices can help prevent MAC cloning and other types of insider attacks.
By implementing these strategies, you can significantly improve the security of your MikroTik network against MAC cloning and other attack vectors. It is important to remember that network security is an ongoing effort and should be reviewed and updated regularly to protect against new threats.
