Software update systems are critical for ensuring systems remain free of bugs and vulnerabilities while they are in service. While many Internet of Things (IoT) devices are capable of outlasting desktops and mobile phones, their software update practices are not yet well understood. This paper discusses efforts toward characterizing the IoT software update landscape through network analysis of IoT device traffic. Our results suggest that vendors do not currently follow security best practices, and that software update standards, while available, are not being deployed. We discuss our findings and give a research agenda for improving the overall security and transparency of software updates on IoT.
