| Abstract: | In the field of enterprise architecture, enterprise architects and risk and security analysts use various modelling applications to demonstrate how the business goals of an organization are aligned with the overall business systems. In this context, one of the most-used modelling languages is ArchiMate, which allows its users to represent the risk and security-related aspects given that it contains an overlay called "Risk and Security" (RSO). However, despite the guidance of the overlay for its users, it has been noted and highlighted by multiple researchers in the field that it generally lacks clarity and expressiveness when it comes to conceptual modelling of risk and security-related notions. To minimize the drawbacks, and to make the conceptual risk and security modelling as efficient as possible, the researchers in the enterprise architecture field proposed redesigning the mentioned overlay by following a thorough ontological analysis. Yet, their redesign conceptual modelling ideas have not been tested. Therefore, to test out the efficiency, contribution and validity of their examinations and conceptual redesign proposals of the overlay, this research paper models the incident of Microsoft Exchange Server Data Breach 2021 to observe how architects and analysts could express architectural risk and security-related matters more clearly and comprehensively by applying the redesigned concepts of the RSO. Furthermore, this research paper compares this model with another established model describing a different incident based on the original version of the RSO to detect the main differences between both original and redesigned versions. |
