HANZO: Collaborative Network Defense for Connected Things

The IoT devices are typically shipped with default insecure configurations and vulnerable software stacks rendering host networks exposed to attacks, especially small networks with no administration. We present a network system model for device configuration and operations management. Using this model, we design and implement an autonomous network management platform with device classification and traffic characterization functions integrated in a network gateway. We evaluate the system using a connected home testbed that combines IoT and general-purpose devices.
