06/2016 - 07/2017
Research associate at School of Computer Science, Georgia Tech.
As a programmer, I worked on one of large research projects in which Georgia Tech partakes for national interests. It was to build a DDoS defense system analyzing incoming traffic, detecting DDoS attacks especially incurred by low volume packets. In this period, I developed a linux kernel module watching system resource usage per packet.
