Abstract:
A Distributed Denial-of-Service (DDoS) assault overwhelms a server, network, or service with Internet traffic, disrupting regular traffic. As the Internet becomes more accessible, the new attack vector includes insecure, Internet-connected IoT devices, and Denial-of-Service (DoS) vulnerabilities in SDN architecture, such as southbound channel saturation. Blockchain technology holds immutable data in blocks without login or address. A coded username established through a unique mechanism makes hacking the blocks virtually impossible. This paper reports on a systematic literature review (SLR) aimed at identifying and structuring research on the use of blockchain to prevent DDoS attacks. We systematically selected and reviewed articles published in suitable venues in this review. The research outcome provides insight into what constitutes the main contributions of the field, identifies vacancies and opportunities, and purifies several predominant future research directions.
