Title: Software-Defined Security

Abstract:
Network security functions have been usually realized as hardware devices to satisfy their performance requirement. While these hardware based security devices are working well in the current network environments, they are now asked to adapt themselves in some new emerging network architectures, such as Software-defined Networking (SDN). In an SDN environment, network devices (not network security devices) can conduct some basic security functions with the help of their control applications. Moreover, with the emergence of Network Function Virtualization (NFV), some pioneering researchers show the possibility of replacing hardware based security devices with virtualized functions. In this talk, I will present how SDN and NFV can be used in implementing new types of security services, and I will also introduce some example scenarios supporting this claim.
