Abstract:

Despite the advances of cybersecurity over the past years, the gap between security risk and defense capabilities is ever increasing. This can be attributed to fundamental standing challenges in cyber security. Firstly, the growing complexity of cyber and cyber-physical systems configurations that usually contain millions of highly inter-dependent rules and variables significantly increases the potential mischaracterizing of the system risk and security threats. Secondly, the asymmetry of cyber warfare, which allows adversaries to plan, launch and propagate attacks while defense strategies exhibit high uncertainty due to unknown attack strategies, increases the potential of attack evasion and success. Thirdly, key system artifacts (e.g., logs and traces) important for estimating the system state become are high-volume and semantically unstructured, which imposes real challenges in reasoning about failures or attacks.

In this talk, I will give an overview of our current and future research to address these challenges and enable next-generation secure and resilient cyber and cyber-physical systems. I will present our research work in data-driven analytics and automation using formal methods, statistical analysis and probabilistic reasoning for improving the trustworthiness, resiliency and assurability of large-scale complex systems. In particular, I will present three main thrusts of my research: (1) our formal analytics for modeling and verification of cyber and cyber-physical system behavior based on configuration and log data, (2) cyber agility using data- and model-driven techniques, and (if the time allows) (3) evidential reasoning and formal analytics combined approach for network diagnosis and prognostication of networks. My research application domains include security analytics of large-scale enterprises and data centers, smart grid, health diagnosis of critical infrastructure, and Software Defined Networking security.
