Digital Resilience in Critical Infrastructures: A Systematic Literature Review

In times of disruptive events, effective response by organizations, critical systems, and society is paramount. The response process involves pre-event preparation, impact absorption, and system restoration, which together represent the concept of resilience. Critical infrastructures (CI) are essential to the functioning of society and require a high level of resilience to ensure that they can withstand and quickly recover from disruptive events. With the incorporation of Information Systems (IS) into CI, there is a need to study Digital Resilience to identify potential risks and develop strategies to mitigate them effectively. In this research, we conducted a Systematic Literature Review on Digital Resilience to understand its scope, and classified articles based on their scope, resilience dimensions, and phases they address, as well as interdependence between systems. We aim to contribute to the scientific understanding of Digital Resilience by analyzing existing gaps and proposing possible future research directions. This study provides an overview of the current state-of-the-art, the types of research conducted, and the resulting artifacts. Additionally, it introduces a new area of focus within the field of resilience: Digital Resilience.
