The Internet of Things (IoT) is an emerging computing paradigm spanning smart home, wearable devices, smart cities, and intelligent transportation systems. Building security into IoT is critical today. However, many unique features in IoT, including device resource constraints, device/vendor diversity, and cross-device physical interactions often make traditional IT security approaches impractical. To address those challenges, in this talk, I will present three of our recent research efforts. First, I will introduce a lightweight malware infection detector for IoT devices. Second, I will present a system that mitigates volumetric DDoS attacks with programmable switches. Third, I will briefly discuss an IoT device physical interaction control system, which can discover real IoT physical interactions and enforce safety and security policies.
