Testing techniques to assess impact and cascading effects

The rapid evolution of digital environments and their integration into critical operations of our society have led to substantial challenges in advancing cybersecurity to ensure the proper functioning of these systems. In the face of over-evolving cyber threats and attacks, systems must be equipped with robust mechanisms for protection. In this context, resilience techniques aim to mitigate such treats. However, the evaluation of these techniques is a crucial process, enabling informed decision-making and proactive threat mitigation. This article introduces a methodology based on regression testing for evaluating the impact and cascading effects of resilience strategies. It delves into the methodology's adaptability across different scenarios and provides insights about the evaluation process.
