ROLE OF BLOCKCHAIN IN COLLABORATIVE DDOS MITIGATION
One of the most serious security threats to network domains is a distributed denial of service attack. Various mitigation mechanisms are widely deployed in various networks or domains, but they lack the resources and resilience to deal with DDoS attacks on their own. Collaborative mitigation systems have been developed to improve the DDoS mitigation capability of a single mitigation system by exchanging mitigation information. However, for collaborative DDoS mitigation architectures, deployment complexity, secure information exchange, and trust remain issues. Block chain technology has recently demonstrated its compatibility with fields such as supply chain management, health care, IoT, and other public services. Because Block chain is distributed in nature and effective in data integrity and transparency, it can integrate with collaborative DDoS mitigation systems. This paper provides an overview of the integration of Collaborative DDoS mitigation systems with Block chain technology. We discuss the history of DDoS mitigation and Block chain, as well as the applicability of Block chain to collaborative DDoS mitigation and open challenges in this area.
