ONTOLOGY-BASED RISK PROPAGATION OVER DIGITAL TWINS

Implementations are directed to methods, systems, and apparatus for ontology-based risk propagation over digital twins. Actions include obtaining knowledge graph data defining a knowledge graph including nodes and edges between the nodes, the nodes including asset nodes representing assets and process nodes representing processes; each edge representing a relation between nodes; determining, from the knowledge graph, an aggregated risk for a first process represented by a first process node, including: identifying, for the first process node, a set of incoming nodes, each incoming node comprising an asset node or a process node and being connected to the first process node by a respective edge; determining a direct risk for the first process; and determining an indirect risk for the first process; and generating, based on the aggregated risk for the first process node, a mitigation recommendation including actions for reducing the aggregated risk for the first process node.
