Dr. Yang's current research focuses on providing Predictive Cyber Situation Awareness and Anticipatory Cyber Defense through the development of ASSERT (Attack Strategy Synthesis and Ensemble pRedictions of Threats), CASCADES (Cyber Attack SCenArio & network Defense Simulator), and CAPTURE (Cyber Attack Prediction of Threats from Unconventional REsources). ASSERT recognizes multistage attack behaviors in enterprise networks and synthesizes statistical models for these behaviors based on large-scale, incomplete and noisy cyber observables. CASCADES generates cyber attack scenarios based on the interplay between adversary capability/opportunity/intent/preference and network defense configurations. CAPTURE aims at forecasting cyber attacks based on unconventional data sources, sensors, and signals. Dr. Yang and his team are developing novel machine learning, data analytics, and simulation techniques as sub-components of the above systems. The ultimate goal of these systems is to enable anticipatory, proactive cyber defense that are agile and resilient to increasingly sophisticated cyber attacks.
The above ongoing works are built upon the earlier work by Dr. Yang’s team who introduced Fuzzy-Variable Length Markov Models (F-VLMM), Virtual Terrain (VTAC), Attack Social Graphs (ASG), FuSIA, and an attack obfuscation modeling framework using statistical graph models.
