Intrusion Detection in the Era of IoT: Building Trust via Traffic Filtering and Sampling

In the Internet of Things (IoT) era, the number of connected devices and subnets of devices is rapidly increasing. Yet, it remains a challenge for intrusion detection mechanisms to build a trust map among various IoT devices because of the devices’ large quantity and dynamic nature. Through a case study, the author highlights the importance of traffic filtration and sampling in evaluating trustworthiness among IoT devices.
