Zhejiang University

I am a Researcher in the Zhejiang University, Schoolof Software Technology . Before joining ZJU, I worked at Huawei, 2012 Lab as a Senior Engineer. I graduated from Department of Computer Science and Technology, Zhejiang University with a Ph.D. degreed.

My research interests lie in system security, intrustion detection and cyber threat analysis techniques. I am now working towards to design practical intrusion detection and attack investigation systems.

“Contact me for intrusion detection systems research that are in line with the industry!!!”（持续招收对安全研究有兴趣的硕士研究生和本科生！）

Marlin: Knowledge-Driven Analysis of Provenance Graphs forEfficient and Robust Detection of Cyber Attacks

Zhenyuan Li, Yangyang Wei, Xiangmin Shen, Lingzhi Wang, Yan Chen, Haitao Xu, Shouling Ji, Fan Zhang, Liang Hou, Wenmao Liu, Xuhong Zhang, Jianwei Ying

Project

  • Marlin conceptualize real-time attack detection in streaming logs as a streaming graph alignment problem, leveraging query graphs to pinpoint critical elements in the provenance graph. Integrated into a tag propagation framework, it processes each event once, reducing redundancy and enhancing efficiency and defense against evasion.

AttacKG: Constructing Technique Knowledge Graph from Cyber Threat Intelligence Reports

Zhenyuan Li, Jun Zeng, Yan Chen, Zhenkai Liang

Project

  • AttacKG can automatically extract structured attack behavior graphs from CTI reports and identify the associated attack techniques, and aggregate threat intelligence across reports to collect different aspects of techniques and enhance attack behavior graphs into technique knowledge graphs (TKGs).
  • AttacKG can empower many downstream security applications such as threat identification, automatic threat reasoning and disposition.
