PNNL-SA-64942 Cyber Analytics Challenges and Solutions for Computer Security Glenn A. Fink, Ph.D. Adaptive Systems Focus Lead Information and Infrastructure Integrity Initiative (I4)
What is Cyber Analytics? PNNL-SA-64942 • Cyber, adj.: Of or relating to computers andcomputer networks • Analytics, n.: The science of analysis • Science: Knowledge about a system based on comparing observations to theoretical models • Analysis: The process of arriving at a decision based on observable facts (data) • Cyber Analytics: • Formal: Observing computer and network data, and quantifiably comparing it to theoretical behavioral models to support decision-making • Informal: Understanding the behavior of computers and computer networks from the data they generate
PredictiveDefense AdaptiveSystems TrustworthyEngineering CyberAnalytics Cyber Analytics is one of four cornerstones for sound, secure computer infrastructures Anticipate and estimatepotential impact of change. Scalable self-defending informationand infrastructures. Increase confidence in informationand infrastructure integrity. Decision-making using predictiveanalysis to support action. PNNL-SA-64942
Distinctive characteristics of Cyber Analytics • The cyber analyst is often on or near the front lines combating intruders and enacting protection measures • Cyber data is massive, real-time, streaming, and often not stored • Cyber protocols are relatively simple and low entropy PNNL-SA-64942

The Road Ahead for Cyber Analytics • Resources needed • Dedicated, standard ranges, freely available • Reference data sets • Science advances needed • Predictive science • Complex-adaptive science • Social/legislative agenda • Cooperation and collaboration • Laws governing use of shared data sets • Privacy protection laws PNNL-SA-64942
PredictiveDefense AdaptiveSystems TrustworthyEngineering CyberAnalytics Conclusions Anticipate and estimatepotential impact of change. Scalable self-defending informationand infrastructures. Increase confidence in informationand infrastructure integrity. Decision-making using predictiveanalysis to support action. • PNNL is making strides defining the research area of cyber analytics • PNNL is investing internal money into solving key cyber analytics problems such as • Automated distributed collection and analysis of cyber data • Environments that support human collaborative analysis and resolution of emerging cyber threats 35
