Harnessing Blockchain for Collective Defense: A Strategy for Detecting and Combating DDoS Attacks

Among the current security challenges faced by the Internet, Distributed Denial of Service (DDoS) attacks loom as a significant threat. DDoS attacks represent potent cyber threats designed to incapacitate services by overwhelming servers, thereby hindering their responsiveness to users. These attacks can swiftly deplete the processing and communication capabilities of the targeted entity. The previous few years have seen a noticeable surge in the frequency and duration of DDoS attacks, rendering them more impactful and perilous. The surge in insecure mobile device usage and escalating traffic volumes contribute to the heightened risk posed by DDoS attacks on various services. This paper proposes a collaborative approach for identifying and mitigating DDoS flooding attacks. The utilization of smart contracts can play a crucial role in identifying malicious actors, subsequently enabling their inclusion in blocklists. Leveraging blockchain technology simplifies the complexity of the DDoS signaling system, offering an effective means for numerous independent and distributed systems to collaborate. Through resource and defense characteristic sharing, blockchain facilitates a robust defense strategy against DDoS attacks.
