Dr. Xuetao Weifrom the School of Information Technology at the University of Cincinnati will give a talk on Monday April 29 at 10:15 - 11:15, in Storey Innovation Center (Room 2277). Abstract: Cyberspace is a constantly changing landscape. Not only security attacks have become more and more stealthy, but also a myriad of opaque security applications have emerged. Navigating the increasingly complex cyber threat landscape has become overwhelming. Thus, it is essential to profile and understand emerging security attacks and applications. In this talk, I will first present a novel approach and tool, which illuminates in-memory injection attacks via provenance-based whole-system dynamic information flow tracking. Then, I will present a framework to enable behavior-based profiling for smart contracts, which could enhance users' understanding and control of contract behavior and assess performance and security implications. Finally, I will briefly discuss current ongoing research and future directions.
