Title: Cyber-security, the journey from Formal Methods, Program
Analysis to Data Analytics

Speaker: Liu Yang, Nanyang Technological University.

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.

Short Bio:
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.
