IoT Network Monitor is an intuitive and user-friendly interface for consumers to visualize vulnerabilities of IoT devices in their home. Running on a Raspberry Pi configured as a router, the IoT Network Monitor analyzes the traffic of connected devices in three ways. First, it detects devices with default passwords exploited by previous attacks such as the Mirai Botnet, changes default device passwords to randomly generated 12 character strings, and reports the new passwords to the user. Second, it conducts deep packet analysis on the network data from each device and notifies the user of potentially sensitive personal information that is being transmitted in cleartext. Lastly, it detects botnet traffic originating from an IoT device connected to the network and instructs the user to disconnect the device if it has been hacked. The user-friendly IoT Network Monitor will enable homeowners to maintain the security of their home network and better understand what actions are appropriate when a certain security vulnerability is detected. Wide adoption of this tool will make consumer home IoT networks more secure.
