Presentation Topic: Cyber Systems Analysis for Critical Infrastructure
Speaker: Dr. Chloe Johansen Applegate, Systems Analyst, Cyber and Infrastructure Resilience Program, Lawrence Livermore National Laboratory

Threats to critical infrastructure come from hazards ranging from natural disasters to malicious cyber-attacks. Planning, prioritization, and communication requires the ability to compare risk across both infrastructure sectors and hazards. The diversity of consequences across sectors, ranging from loss of critical resources (such as power) to health and safety, impedes direct comparison. A common set of frameworks and is needed to understand dependencies of all-hazards infrastructure disruptions, capture diverse cascading effects, and enable cross-sector comparisons.
This presentation will discuss systems analysis within LLNL’s Cyber and Infrastructure Resilience program, which is conducting research and developing tools to enable secure, sustainable, resilient, and reliable infrastructure through improved design and operation. LLNL leverages techniques used in the security of nuclear weapons to quantify risk to cyber and cyber/physical systems from an intelligent adversary (i.e., one that does not behave in a purely probabilistic manner) and develop appropriate mitigation options using science-based, threat-informed methods.


Dr. Chloe Applegate is a Systems Analyst at Lawrence Livermore National Laboratory and the Deputy Associate Program Leader for Cyber Systems Analysis. She has a B.S. in Civil Engineering from the University of Florida, and a M.S. and Ph.D. in Civil Engineering from Georgia Tech. Chloe leverages a background in interdependent critical infrastructure to develop tools and frameworks to provide all hazards risk assessment, interdependency analysis, and cybersecurity recommendations to sponsors within the U.S. Department of Homeland Security and Department of Energy.
