Over the past several months, CITP-affiliated Ph.D. student Sarthak Grover and fellow Roya Ensafi been investigating various security and privacy vulnerabilities of Internet of Things (IoT) devices in the home network, to get a better sense of the current state of smart devices that many consumers have begun to install in their homes.
To explore this question, we purchased a collection of popular IoT devices, connected them to a laboratory network at CITP, and monitored the traffic that these devices exchanged with the public Internet. We initially expected that end-to-end encryption might foil our attempts to monitor the traffic to and from these devices. The devices we explored included a Belkin WeMo Switch, the Nest Thermostat, an Ubi Smart Speaker, a Sharx Security Camera, a PixStar Digital Photoframe, and a Smartthings hub.
