About Abigail

Dr. Abigail Koay is a Research Fellow at the Department of Computer Science, University of Waikato. She received her Bachelors of Computer Science from University Malaysia Pahang, Malaysia and her Ph.D. in Engineering (Network Security) from Victoria University of Wellington, New Zealand. Her Ph.D. research focuses on detecting Distributed Denial of Service (DDoS) attacks on large-scale networks. She studies the use of entropy-based features and the applicability of machine learning algorithms in detecting various intensity DDoS attacks. She also applies software-defined networking technology to address some of the network architecture issues in detecting DDOS attacks from multiple locations in the network. Abigail’s current research interest are Network Security, Traffic Anomaly Detection, Anomaly Detection in IoT Devices, Software-Defined Networking and Applied Machine Learning.

I am currently looking for a student to work on "Project #23 - Traffic Classification and Anomaly Detection using Poseidon" under the University of Waikato Summer Research Scholarships over summer 2019/2020. If you are interested, please find more details of the project and application eligibility at
