Abstract: 
Cyber-security is a complex system research, which requires the knowledge and understanding cross all layers of the computer architecture. In this work, I would like to share our attempts to solve security problems using various techniques. Starting from formal methods, we have applied formal modeling and reasoning to security designs and implementations on the topics related to security protocols, virtualization systems and Android apps. These efforts lead to our recent research project "Securify A Compositional Approach of Building Security Verified System”, which aims at building secure and verifiable systems ground-up. Security verification and building attack-free systems are very challenging tasks in view of the size and the complexity of the systems. To solve the scalability problem, we start to explore various program analysis to enhance the state-of-the-art malware and vulnerability detection, which generates encouraging results in Javascript/Android malware and binary vulnerabilities hunting. Along the way, we have collected size malware/vulnerabilities samples, which are currently used to improving security analysis, understand the security trend, attack attribution/correlation and eventually provide high-level intelligence.

Biography:  
Dr. Liu Yang graduated in 2005 with a Bachelor of Computing (Honours) in the National University of Singapore (NUS). In 2010, he obtained his PhD and started his post doctoral work in NUS, MIT and SUTD. In 2011, Dr Liu is awarded the Temasek Research Fellowship at NUS to be the Principal Investigator in the area of Cyber Security. In 2012 fall, he joined Nanyang Technological University as a Nanyang Assistant professor. He is currently the director of the cybersecurity lab in NTU.
 
Dr. Liu specializes in software verification, security and software engineering. His research has bridged the gap between the theory and practical usage of formal methods and program analysis to evaluate the design and implementation of software for high assurance and security. His work led to the development of a state-of-the-art model checker, Process Analysis Toolkit (PAT). This tool is used by research institutions in over 80 countries for research and education. By now, he has more than 150 publications in top tier conferences and journals and is leading a research team of 30 researchers.
