Analysis, Implications, and Challenges of an Evolving Consumer IoT Security Landscape

The Internet of Things (IoT) is a rapidly growing subset of our modern computing architecture, and as such, provides significant new attack surface. The history of IoT has provided a substantial body of topics to look back on: IoT's evolution, products, and major security incidents including the largest botnet ever witnessed. Unique to IoT, its architecture, interaction design, and scale make its many issues distinct from those in the Internet of Computers (IoC). Its perceptions, understandings, and definitions have evolved over time, thus requiring an updated focus from the perspective of security and cyberphysical safety. We take a fresh look at challenges and opportunities in IoT security, the characteristics that uniquely distinguish it from the IoC, and identify security-related questions that they raise. Our aim is to provide an up-to-date view of the IoT security landscape and technical security issues to help guide both existing and especially new researchers looking for challenging open problems that remain largely unaddressed.
