Navigating the Aftermath: An Empirical Investigation of Response Timeliness and Strategy for Data Breach

In today's digital landscape, data breaches threaten organizational stability and investor confidence. This study aims to investigate the relationship between the timeline, types of security incidents, corporate responses, and their impacts on the stock market recovery. This research extends the prior work by examining the sequential timeline from the occurrence of the breach to the recovery phase. The study categorizes data breach types and analyzes the effectiveness of different response strategies, such as apology, compensation, collective actions, defensive measures, and justification, in restoring company stock value to the pre-breach level. This study helps to bridge the existing gaps in the literature by covering the impact of the specific timing of sequential breach events on data breach announcements on Cumulative Abnormal Returns (CAR). This study contributes to both theoretical and practical understanding by providing deeper insights into post-breach crisis management and strategies for stock market recovery.
