DEFT: A Distributed IoT Fingerprinting Technique

Identifying IoT devices connected to a network has multiple security benefits, such as deployment of behavior-based anomaly detectors, automated vulnerability patching of specific device types, dynamic attack mitigation, etc. In this paper, we look into the problem of IoT device identification at network level, in particular from an ISP's perspective. The simple solution of deploying a supervised machine learning algorithm at a centralized...
