Abstract

This dissertation examines the potential integration of Complex System Governance (CSG) within cybersecurity, emphasizing the development of a reference model for Cybersecurity Infrastructures. Traditional strategies for securing digital environments have struggled to address the intricate and dynamic layers inherent in modern cybersecurity systems. The purpose of this research is to explore the applicability of CSG as a framework to assess cybersecurity infrastructure using a case study research design. The research addresses two key questions: (1) How can the CSG reference model be adapted to explore cybersecurity infrastructure? (2) What results from CSG based exploration of cybersecurity infrastructure through a case study application?

Through a qualitative methodology, the study utilizes a case study to investigate CSG fundamentals and their applicability to cybersecurity. By analyzing existing cybersecurity governance practices, the research identifies shortcomings and explores how CSG can bridge gaps. Findings reveal that CSG offers a structured approach to managing the dynamic, holistic, and emergent nature of cybersecurity threats, which traditional methods like the Department of Defense’s Military Decision-Making Process (MDMP) fail to adequately address. Despite its limited application in cybersecurity, CSG’s foundation in governing complex systems highlights its potential.

The significance of this research lies in advancing cyber governance by introducing CSG as a novel approach. The proposed model has the potential to effectively secure and manage Cybersecurity Infrastructures, while addressing both critical social needs and technical requirements. Implications of this study include providing policymakers and stakeholders with practical insights into governance strategies and contributing to the theoretical evolution of cybersecurity management frameworks. This work establishes CSG as a promising framework to navigate the complexities of cybersecurity, offering pathways for improved governance models tailored to the ever-changing demands of digital ecosystems.
