IT security: Exploring the Benefits of Cloud Computing for Incident Response

Abstract: This study examines the potential of Cloud Computing in enhancing incident response in IT security. It explores how cloud computing features, such as rapid elasticity and on-demand self-service, can positively impact IT infrastructure decisions during incident response scenarios. Through interviews with IT security consultants, insights are gathered on the interplay between incident response and Cloud Computing. The research findings highlight the significant economic impact of security incidents that emerges as a critical concern for organizations. Furthermore, the study reveals that the aftermath of an incident presents a unique opportunity to strengthen an organization's security posture, which aligns with the theory that security measures are often perceived as unnecessary until a breach occurs. This study demonstrates that leveraging cloud computing characteristics can yield several advantages for IT infrastructure decisions in incident response scenarios in terms of speed and efficiency, and that Cloud Computing offers the potential for improved visibility, ease of investigation, and inherent security measures. However, organizations need to address the challenge of acquiring the necessary expertise to securely utilize cloud resources. The time aspect emerges as a prominent benefit, as cloud resources can be rapidly provisioned compared to the lengthy process of acquiring and implementing hardware. Overall, cloud computing presents a viable option for rebuilding IT infrastructure after security incidents, particularly when functional backups are lacking.
