A Comprehensive Review of DNS-based Distributed Reflection Denial of Service (DRDoS) Attacks: State-of-the-Art

Cyberattacks significantly impact the services based on the internet that is used in our daily lives. Any disruption will make it extremely difficult for us to carry out our daily activities. Cyberattacks will disrupt online services, exploit vulnerabilities to breach databases and servers, and so on. Various systems and services contribute to the Internet’s seamless functionality. The Domain Name System (DNS) is one of the most important services. DNS is used to resolve domain names into machine-readable IP addresses. DNS, like many other Internet services, is vulnerable to cyber-attacks. While DNS faces a slew of threats, one in particular appears to stand out. DNS is vulnerable to a variety of distributed denial-of-service attacks. The distributed reflection denial of service (DRDoS) attack, a flooding attack against DNS servers that renders them unavailable, disrupting domain name resolution activities, is one of the most common variants. DRDoS attacks have been on the rise in recent years. DNS lookup outages would significantly impact our online activities in the world of ultra-connectivity because they are typically the first step in establishing a connection with a server. The purpose of this paper is to present a state-of-the-art review of DRDoS attack detection and mitigation algorithms as well as the datasets on which these algorithms operate. Finally, we discussed each of these algorithms' relative merits and demerits.
