Abstract: The goal of this industrial PhD is to investigate how to include resilience into a cyber-security strategy to safeguard vital infrastructure. Critical infrastructure is increasingly susceptible since businesses are using technology more often. These infrastructures are also components of a vast, integrated, and increasing digital supply chain that transcends national boundaries, adding to the difficulties. A bigger attack surface where an attacker might use vulnerabilities contained in suppliers' and sub suppliers' chains could come from this extension of the digital supply chain. The study will add to our understanding of how to manage intricate supply chains in critical infrastructure with stringent dependability requirements. The digitalization processes in the supply chain include changes to the organizational structure, necessitating a robust strategy for continual improvement. The research question for this project is as follows: How can a resilience framework contribute to managing the complex digital supply chain for stakeholders in the power industry? The system dynamic (SD) approach will be used to generate a simulation based on the findings from each of the methods. Previous supply chain research has demonstrated that SD modelling is an effective strategy for building resilience in supply networks. To comprehend and examine the behavior of dynamic and complex systems, the notion of SD was established. The theory of system dynamics is based on the idea that actions done in systems will change the system, which will then lead to new actions. To collect primary data the qualitative method chosen as most suitable the semi-structured interview. To understand a social phenomenon, one needs to listen to people who reflect on their own experiences, knowledge, and motivation. Through interviews, it is possible to go into depth on the phenomenon and gather complex and rich data that is not available through literature review only. Contributions from this Ph.D. study are grouped into two categories: academia and organization. Further understanding regarding supply chain vulnerability and the implementation of potential techniques and ideas in novel contexts are academic contributions. The development of the resilience framework, which aims to address the difficult problem of managing stakeholders in the digital supply chain, is a contribution made by the organizations. The goal for CIs is to have resilient DSCs that can withstand and improve from high-pressure situations. Improving DSC resilience requires an understanding of the supply chain network that includes suppliers’ and their sub-suppliers’ incentives, all the way to its downstream customers’ incentives. By understanding the structure of the system, the ability to ascertain the behavior of the system increases, providing opportunities to better manage the system. If we can harness the positive incentives for collaboration and social connection the road to a more resilient CI that is available when the society require it becomes easier.
