IoTDevID: A Behaviour-Based Fingerprinting Method for Device Identification in the IoT
share
Device identification is one way to secure a network of IoT devices, whereby devices identified as suspicious can subsequently be isolated from a network. We introduce a novel fingerprinting method, IoTDevID, for device identification that uses machine learning to model the behaviour of IoT devices based on network packets. Our method uses an enhanced combination of features from previous work and includes an approach for dealing with unbalanced device data via data augmentation. We further demonstrate how to enhance device identification via a group-wise data aggregation. We provide a comparative evaluation of our method against two recent identification methods using three public IoT datasets which together contain data from over 100 devices. Through our evaluation we demonstrate improved performance over previous results with F1-scores above 99 aggregation.
