Internet-connected devices are increasingly present in our homes, and privacy
breaches, data thefts, and security threats are becoming commonplace. In order
to avoid these, we must first understand the behaviour of these devices.
In this work, we analyse network traces from a testbed of common IoT devices,
and describe general methods for fingerprinting their behavior. We then use the
information and insights derived from this data to assess where privacy and
security risks manifest themselves, as well as how device behavior affects
bandwidth. We demonstrate simple measures that circumvent attempts at securing
devices and protecting privacy.
