From September 2024, I work at Division of Artificial Intelligence Engineering, Sookmyung Women’s University (SMWU), Seoul, Republic of Korea, as an assistant professor.

Research goal

I investigate and address cybersecurity challenges in Internet service applications through a data-driven approach that utilizes machine learning and deep learning methodologies. My research involves analyzing massive live data streams to secure computer systems and networks from evolving threats, leveraging experience with diverse datasets including massive online games, root DNS servers, mobile payment transactions, and car hacking activities. I have specialized in identifying and explaining intrusions in connected vehicles, notably employing anomaly detection techniques trained solely on benign data. (ORCID: 0000-0001-5638-2851)

My current research interests center on Trustworthy Network Intrusion Detection using Foundation Models. I aim to move beyond simple classification accuracy to build systems that are robust, adaptive, and explainable. Key areas include:

  • Multi-modal Traffic Representation & Pre-training: Integrating payload bytes, packet sequences, and protocol metadata to learn comprehensive traffic representations without information loss.
  • Drift Resilience & Efficient Adaptation: Developing unsupervised metrics to detect concept drift in real-time and utilizing parameter-efficient fine-tuning (PEFT) to adapt models to new environments with minimal cost.
  • Generative & Causal Reasoning: Applying generative AI to not only detect threats but also explain their causes (causal reasoning) and suggest response scenarios.

I am currently working on an Explainable Unsupervised IDS for Automotive Ethernet, which applies these foundation model principles to secure in-vehicle networks against complex intrusions. I am also developing DRIFT (Drift-Resilient Invariant-Feature Transformer), an advanced DGA detector. DRIFT employs a hybrid tokenization strategy (character + subword) and multi-task self-supervised pre-training to maintain robust detection performance against temporally evolving domain generation algorithms.
