A Review : Distributed Denial-of-Service (DDoS) attack

A Distributed Denial-of-Service (DDoS) attack is a type of cyber-attack in which a large number of compromised computers are used to flood a targeted system or network with traffic, making it unavailable to users. DDOS attacks have become a serious threat to online services, and detecting and mitigating them has become a major challenge for security professionals. In this review paper, we provide an overview of the different types of DDoS attacks and their characteristics, including volumetric attacks, protocol attacks, and application layer attacks. We discuss the various techniques used by attackers to launch DDoS attacks, including botnets, amplification, and reflection attacks. Review the different defense mechanisms that have been proposed to detect and mitigate DDoS attacks, including network-based and host-based approaches, as well as hybrid approaches. We discuss the limitations of these approaches and highlight some of the open research challenges in this area. In this paper to provide an evaluation of the current state-of-the-art in DDoS attack detection and mitigation and identify some of the future research directions in this field. Our review paper provides a comprehensive overview of the DDoS attack landscape and aims to provide useful insights for researchers, practitioners, and policymakers who are interested in this area.
