Identifying Blind Spots in IS Security Risk Management Processes Using Qualitative Model Analysis
Christian Sillaber, Ruth Breu · Lecture notes in computer science · 2015
The present paper examines quality aspects of models created by stakeholders to identify blind spots in information systems security risk management (ISSRM) processes via a multi-method research study at the organizational level. Stakeholders were interviewed to gain an understanding of their awareness of business processes, models of the information system (IS), and related security requirements in the context of an ongoing ISSRM process. During several modeling sessions, stakeholders were asked to model various aspects of the IS under investigation in the form of component, activity and business process diagrams. We then analyzed the created models qualitatively and linked identified inconsistencies to security issues omitted during the ISSRM process (blind spots). The findings indicate that various quality aspects of models created by stakeholders that describe either the IS or related business processes can contribute to an improved ISSRM process, better alignment to the business environment and improved elicitation of security requirements. Following current research that considers users as the most important resource in ISSRM, this study highlights the importance of using and analyzing model diagrams from appropriate stakeholders at the right time during the ISSRM process to identify potential blind spots and avoid unclarity, that might be introduced by verbal communication. The research provides risk managers with a process for identifying blind spots to improve results and reduce overhead.
