IoT botnets have been used to take down some of the biggest services on the Internet in the fall of 2016.
This project investigates methods used to protect IoT devices behind IGDs from IoT botnets like Mirai. This is done by filtering traffic to and from the devices, using the firewall on an IGD.
The solution is based on a system that generates profiles throughout a learning phase. These profiles provide information about the traffic to and from each IoT device connected to the IGD. The learning phase is automatically started when new devices are connected to the IGD.
When the learning phase has ended, a set of firewall rules is generated for the device and loaded into the IGD’s firewall. In the final system evaluation, the results show that the firewall rules, generated for the IGD, prevent botnets from spreading and participating in attacks.
