Building a Cybersecurity Risk Metamodel for Improved Method and Tool Integration

Abstract: Nowadays, companies are highly exposed to cyber security threats. In many industrial domains, protective measures are being deployed and actively supported by standards. However the global process remains largely dependent on document driven approach or partial modelling which impacts both the efficiency and effectiveness of the cybersecurity process from the risk analysis step. In this paper, we report on our experience in applying a model-driven approach on the initial risk analysis step in connection with a later security testing. Our work rely on a common metamodel which is used to map, synchronise and ensure information traceability across different tools. We validate our approach using different scenarios relying domain modelling, system modelling, risk assessment and security testing tools.
