Abstract
Computing platforms are evolving from desktops to Smartphones to the Internet of things (IoT) devices. In this change, computer systems have started embedding an amazing variety of interaction points in both software and hardware forms. While such changes have made everyday life easier by enabling various convenient features, protecting these systems has become much more difficult. This is not only because system complexity has increased with the integration of more interactions and often conflicts with the existing security mechanisms, but also because improper security practices or incomplete security checks result from faster production cycles that generally lead to more security holes.
In this talk, Yeongjin will present his research on protection of computing system interactions. First, he will present Gyrus, a user interaction monitoring system that reflects user's intention to network traffic monitoring. Gyrus can protect user-to-network interactions such as sending message online and online banking. Next, he will present security analysis results at system interaction points, including the user interface of popular operating systems and the USB cable channel of Apple iPhone. These analyses found several critical security vulnerabilities, and he will discuss countermeasures against those vulnerabilities to keep the affected systems secure.
