Talk Title: Protecting Computing System Interactions
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium.
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 a result of security analysis on user I/O in operating systems,
in which he discovered computer accessibility as a new attack vector. The analysis found 12 new attacks in popular operating systems, and he discusses countermeasures against the vulnerabilities to keep the affected systems secure.
Biography: Yeongjin Jang is a Ph.D. candidate in Computer Science at the Georgia Institute of Technology. His research focuses on security and privacy problems of computing systems, which include operating systems, mobile systems, and computing hardware.
His research results are recognized for their highly practical impact, as noted by one award and two nominations for the CSAW best applied research paper. Moreover, his research has been widely covered in popular media including Forbes, Wired, MIT Technology Review, and more.
Yeongjin received his M.S. from Georgia Tech in 2016 and B.S. from KAIST in 2010.
