Using semi-supervised learning, I propose an anomaly-based network intrusion detection system (NIDS) to detect and classify anomalous and/or malicious traffic. With this proposed machine learning approach, we detect botnet traffic and distinguish it from the normal and background traffic in the IPv4 flow datasets. I evaluate the prediction performance results for the flow-based NIDS algorithms. I show an improvement in detection accuracy and reduction in error rates, when compared with signature-based NIDS and previous studies.

About the Speaker

Nandi Leslie
Dr. Nandi Leslie is an Engineering Fellow at Raytheon Technologies, serving as an Applied Mathematician and Principal Investigator at the U.S. Combat Capabilities Development Command/Army Research Laboratory (ARL)customer, since 2015. She supports the Raytheon Intelligence and Space business area and ARL on research and development projects related to machine learning, and cyber and electromagnetic activities. Dr. Leslie has published over 40papers in journal, conference proceedings, magazines, and government technical reports on machine learning,cybersecurity, network resilience, submarine security, and mathematical biology with over 375 citations. She has given over 30 research talks at national and international conferences in both unclassified and classified settings

Before joining Raytheon, Dr. Leslie led and contributed to multi-target tracking projects at Systems Planning and Analysis, Inc. from 2007 to 2015. In this role, she served as Program Manager and Senior Operations Research Analyst, and she developed modeling approaches for the U.S. Navy Submarine Security Program, Office of the Secretary of Defense (OSD), and Joint Program Offices, using stochastic processes, to understand various tactical problems in different domains; such as submarine search and detection in oceanographic and atmospheric environmental conditions for the Navy, and damage assessments and remediation of cyber attacks to the Defense Industrial Base for OSD. In addition, she spent two years as a Lecturer and Postdoctoral Researcher at the University of Maryland, College Park in Department of Mathematics from 2005 to 2007. She earned her Ph.D. in Applied and Computational Mathematics from Princeton University in 2005, where her research focused on developing and analyzingspatially-explicit stochastic models of deforestation in forest ecosystems of the Neotropics.

Summer Series seminars are at 1pm (ET) on Wednesdays and will be posted later on our YouTube channel.
