Evolution of Incident Response Plans: Lessons from Prominent Cybersecurity Breaches

Developing incident response plans (IRPs) has become progressively essential following prominent cybersecurity attacks. This research study analyses the evolution of Incident Response Plans (IRPs) by evaluating insights gained from significant breaches, such as the Target data breach, the Equifax breach, and the WannaCry ransomware assault. These case studies underscore risks, effective strategies, and the imperative for proactive measures, including regular Incident Response Plans (IRPs) updates and extensive team training. This document presents a systematic methodology for creating resilient Incident Response Plans to mitigate cybersecurity threats. This study examines the integration of new technologies, including artificial intelligence (AI), machine learning (ML), and blockchain, into Incident Response Plans (IRPs) to improve their efficacy and adapt to the swiftly changing threat environment.
