Abstract:Securing the energy delivery system (EDS) from complex, nonlinear, and evolving cyber threats requires a complex set of changing and interwoven classes of technologies, policies, relationships, and personnel. One key area in this technological milieu is assessment methodologies to compare information, gathered by a variety of means, about networked devices with publicly known possible threat information about said devices. This information is used to generate risk-based characterizations that allow for the adjudication and proper corresponding management action chains to be assigned. \color{blue}To address the current cybersecurity needs in the operational technology (OT) domain, we developed a novel relative-risk assessment framework and a software application called MEEDS that can detect exposed OT systems. This paper presents the detailed architecture of relative-risk assessment framework methodology and its integral role in the MEEDS software. The efficacy of the presented framework is demonstrated by testing with the real-world systems and vulnerabilities pertaining to the industrial control systems (ICS) in critical infrastructures.
