Blockchain Technology towards the Mitigation of Distributed Denial of Service Attacks

Abstract

The Distributed Denial of Service attack become one of the most adverse effects among all Cyber-attack due to the high availability of the internet and unprotected internet-connected communication devices. There are many mitigation solutions available to reduce the risk of DDoS attacks, and the researcher represents many techniques to get rid of the DDoS attacks. The main challenge to identify and mitigate the attack is that attack traffic mixes with the legitimate system user traffic so it becomes very important to block the attack traffic because it costs in terms of money and system reputation. Blockchain technology presents the ideology of decentralized distributed database and transaction without the need of any central authority. But utilization of blockchain is not only limited to the financial sector but supply chain, IoT, hospitality sector used blockchain most. The most attractive features of the blockchain like immutability, distributed makes the use of blockchain for mitigation of various Cyber-attacks, and one of them is DDoS Attacks. The solution of DDoS attacks that utilize the blockchain is still in the infancy phase. In this paper, we propose the review or survey of DDoS attacks solutions based on blockchain. And also present the comparative study of Blockchain-based DDoS mitigation solutions for non-IOT domain or system. This paper also gives brief about the features of this interconnection of two emerging domain named DDoS Attacks and Blockchain Technology.
