I'm a network security engineer with 7 years of experience in the field and currently a member of Netlab(Qihoo 360) where I focus on network/passive-dns data process/analysis and threat research. Before joining NetLab(Qihoo 360), I was a security engineer in NSFOCUS and has been involved in many different projects, like SoC architecture design and implementation, and intranet-traffic anomaly detection.
