Threat Modeling of Cyber-Physical Systems - A Case Study of a Microgrid System

Cyber threat modeling is an analytical process that used for identifying the potential threats against a system and supporting selection of security requirements in early stages development life cycle. Thus, vital instrument realization secure-by-design principle. Despite being well-known practice software projects, its adaptation to cyber-physical systems still requires systematic elaboration. The complex interactions between cyber physical spaces their reflection on landscape constitute significant challenge teams. This study proposes detailed methodology apply STRIDE demonstrates applicability case microgrid system. Our provides elicitation procedure based attack taxonomy was created this research. paper also shows how assets could be identified, data flow diagrams formed, trust boundaries determined, prioritized,
