The significant increase in Internet of Things (IoT) devices, which routinely collect sensitive information, is demonstrated by their prominence in our daily lives. Although such devices have simplified and automated everyday tasks, they have also introduced tremendous security flaws. The insufficient security measures that are currently being employed to defend these smart devices make IoT the 'weakest' link to breaking into a secure infrastructure, and therefore an attractive target for cyber-attacks. This project will focus on investigating Radio Frequency vulnerabilities on IoT devices and mechanisms to defend against them.
