摘要
Methods and systems are disclosed for security management in an industrial control system (ICS). An event entity detection and linking module generates a model for a plurality of event entities extracted from a plurality of different data sources including one ICS data source and one IT data source. The model encodes a set of linked event entities and their relationships, each event entity associated with a vector of attributevalue pairs. A data standardization of domain knowledge includes translating, by a machine learning application, extracted knowledge base information to rules for the constraints and using the rules to validate the constraints and to add new constraints. A fusion module performs temporal correlation detection across data streams of the different data sources for establishing causality between triplets of association models within a defined time span.
