Abstract
A method, apparatus and system for determining a weakness or risk for devices of an Internet-of-things (IoT) network include determining a representation of a physical environment of the IoT network and expected physical and cyber interactions between the devices of the IoT network based at least in part on operating characteristics of the devices of the IoT network, monitoring the physical environment and actual interactions between the devices to generate a network model including at least one of uncharacteristic physical or cyber interaction paths between the devices, based on the determined network model, determining at least one weakness or risk of at least one of the IoT network or of at least one of the devices, and providing a metric of security of at least one of the IoT network or of at least one of the devices based on at least one of the determined weakness or risk.
