Abstract
A Cyber Vulnerability Assessment Tool (CVAST) and CVAST Threat Assessment Heuristic (CVAST THRASH) capable of automated modeling of cyber physical systems, assessment of the nature of cyber risks thereto, and output of such cyber risk assessments are provided.
Claims10
A computer system capable of implementing a Cyber Vulnerability Assessment Tool (CVAST) for conducting and outputting a cyber risk assessment of a Cyber Physical System (CPS), comprising:
- a CPS Information Extraction System for extracting information from a data source;
- a CPS Semantic Model for modeling relationships across a plurality of domains;
- an Attack Graph Algorithm for analyzing a path from an entry point to a target using an electrical circuit analogy;
- a Chain of Impacts Algorithm for evaluating a chain of cyber threat impacts;
- a CPS Criticality Algorithm for evaluating a criticality of a system, a subsystem, or a component;
- a THRASH Cyber Risk Algorithm for evaluating the cyber risk at component and system levels of the CPS.
