> Security has become one of the major concerns for today’s internet. End users, however, are slow in adopting new security technologies. Many users cannot do good security management by themselves. Still, IT managers desire efficient and scalable protection mechanisms.
> 
> Toward solving these issues, in this talk, Dr. Li will introduce two of his efforts he worked on at Northwestern University. First, he will present the design of NetShield, a new vulnerability signature based NIDS/NIPS, that achieves high throughput comparable to that of the state-of-the-art regular expression based systems while offering much better accuracy. In particular, he proposes a candidate selection algorithm that efficiently matches thousands of vulnerability signatures simultaneously and designs a parsing transition state machine that achieves fast protocol parsing.
> 
> Second, Dr. Li will talk about WebShield, a secure web proxy design that protects clients from web-based exploits by processing potentially malicious JavaScript in a sandboxed environment (shadow browser) on a middlebox. With shadow browsers, WebShield also aims to deploy client-based defenses against various classes of web attacks without client modifications.

> Zhichun Li currently is a research staff member at NEC Research Laboratories. Before joining NEC, he received his Ph.D. in December 2009 from Northwestern University and continued working there as a research associate for half a year. He earned both his M.S. and B.S. degrees from Tsinghua University in China. His research interests span the areas of security, networking and distributed systems with an emphasis on network security, web security, smartphone security, cloud security, social network security, network measurement and distributed system diagnosis. He has conducted research at Microsoft Research Redmond and the International Computer Science Institute (ICSI) of UC Berkeley.
