The complexity of enterprise architectures and the associated IT security risks are constantly increasing. Traditional approaches to IT risk management operate in silos and make it difficult to obtain a company-wide view of existing threats. The objective of this thesis is to develop an assessment framework that enables an automated comprehensive view of existing IT security risks within the enterprise architecture. For this purpose, concepts of IT risk management are extended with principles of enterprise architecture management. Based on a research approach according to the design science research paradigm, an artifact, the so-called Enterprise Architecture Management Risk Assessment (ERA) framework, will be developed based on a problem analysis and requirements gathering from practice and science. The ERA framework will be prototypically implemented and evaluated as a dashboard solution in a case study with a German bank. The evaluation will take place in two iterations, qualitative by means of expert interviews and quantitative by means of a survey. The evaluation of the ERA framework artifact and its prototypical dashboard implementation confirms its usefulness, usability and non-triviality. Furthermore, possible extension and improvement possibilities of the artifact are disclosed. The designed evaluation framework contributes to research at the interface of IT security and enterprise architecture management as well as to the solution of a practical relevant problem.

Zusammenfassung der Kapitel (Chapter Summaries)
Chapter 1: Introduction: This chapter introduces the problem of increasing complexity in enterprise architectures and associated IT security risks, highlighting the limitations of traditional, siloed risk management approaches. It establishes the need for an automated, comprehensive assessment framework and outlines the thesis's objective: to develop the Enterprise Architecture Management Risk Assessment (ERA) framework. The chapter lays the groundwork for the subsequent chapters, explaining the research methodology and the structure of the thesis.
Chapter 2: Related Work: This chapter reviews existing literature on IT risk management and enterprise architecture management, identifying relevant concepts and approaches. It analyzes the strengths and weaknesses of current methodologies for assessing IT security risks and lays the foundation for the design of the novel ERA framework. This section explores the gaps in existing literature that the thesis intends to address, contextualizing the significance of the proposed framework within the current state of the field. The analysis of previous works critically evaluates their effectiveness and limitations, leading to a clear justification for the need for a new approach.
Chapter 3: Methodology: This chapter details the research methodology employed in developing the ERA framework. It explains the adoption of the design science research paradigm, outlining the iterative process of problem analysis, requirements gathering, artifact design, prototyping, implementation, and evaluation. This section justifies the selection of the design science research approach and explains how this approach is used to guide the development and evaluation of the ERA framework, demonstrating a clear understanding of the research process.
Chapter 4: Development of the ERA Framework: This chapter presents the detailed design and development of the ERA framework. It describes the architecture, functionality, and key components of the framework, explaining how it integrates concepts from IT risk management and enterprise architecture management. The chapter elaborates on the design choices and decisions made during the development process, justifying the selected architecture and functionality based on the requirements gathered in previous chapters. It outlines the technical details of the ERA framework, providing a clear understanding of its inner workings and capabilities.
Chapter 5: Case Study and Evaluation: This chapter describes the prototypical implementation and evaluation of the ERA framework as a dashboard solution within a case study with a German bank. The evaluation, conducted in two iterations—qualitative via expert interviews and quantitative via a survey— assesses the usability, usefulness, and non-triviality of the framework. The findings of both qualitative and quantitative evaluations are presented, including feedback from experts and survey participants. The chapter analyzes the results, highlighting strengths and weaknesses of the implemented framework and identifying potential areas for improvement.
