INCOSE Critical Infrastructure Protection and Recovery Working Group Seminar

A Data Processing Pipeline for Socio-Technical Network Analysis

Gabriel Weaver
Senior Critical Infrastructure Analyst
Idaho National Laboratory

Abstract

With the rapid adoption of emerging technologies, there is a need to catalog and model sociotechnical interdependencies that have been historically used to influence the operation of Critical Infrastructure networks including the impacts of mergers and acquisitions, hostile takeovers, and foreign investment. 

Our research intends to address this need with two primary contributions.  First, we have developed a data curation and processing pipeline to generate sociotechnical networks extracted from a variety of data sources including SEC filings and infrastructure asset databases.  The pipeline, implemented in Apache Airflow, extracts and normalizes the representation of entities and relations, specified within ontologies.  Second, networks produced by our pipeline enable the development of graph-theoretic metrics that consider the properties of network components in addition to its topology. 

Measures of network complexity, such as degree distribution, reachability analyses, temporal analysis, and community detection may be adapted to indicate adversarial organizational influence.  Our intent is to provide an extensible, machine-actionable approach to quickly communicate such models, reproduce previous results, and adapt them to new, unanticipated situations.

Biography

Gabe Weaver is a Senior Critical Infrastructure Analyst at the Idaho National Laboratory (INL). Weaver’s research focuses on ways to analyze cross-organizational, inter-infrastructure risk as modern information systems are increasingly used to control and monitor critical infrastructure systems.  Prior to INL, as a Research Scientist at the University of Illinois at Urbana-Champaign, Weaver focused on ways to assess the resilience of critical infrastructure systems with a focus on the Maritime Transportation System.  Weaver holds a Ph. D in Computer Science from Dartmouth College; his dissertation was Security-Policy Analysis with eXtended Unix Tools and advised by Professor Sean Smith.  He also holds a B.A. in Classics and Mathematics from the College of the Holy Cross.
