Abstract
Modern Information System (IS) development supports different techniques for business process modelling. Recently Business Process Model and Notation (BPMN) has become a standard that allows modelers to visualize organizational business processes. However, despite the fact that BPMN is a good approach to introduce and understand business processes, there is no opportunity to address security concerns while analysing the business needs. This is a problem, since both business processes and security concerns should be understood in parallel to support a development of the secure systems. In current thesis we introduce the extensions for BPMN 2.0 regarding security aspects. The following proposal is based on alignment of the modelling notation with IS security risk management (ISSRM).We apply a structured approach to understand major aspects of BPMN and propose extensions for security risk management based on the BPMN alignment to the ISSRM concepts. We demonstrate the use of extensions, illustrating how the extended BPMN could express assets, risks and risk treatment on few running examples related to the Internet store assets’ confidentiality, integrity and availability. We believe that our proposal would allow system analysts to understand how to develop security requirements to secure important assets defined through business processes.
We also attempt to observe the following approach in the broader sense and we open a possibility for the business and security model interoperability and the model transformation between BPMN and another modelling approach also aligned to ISSRM, Secure Tropos.
