ABSTRACT
Novel defenses are required due to the increasing complexity of cyber threats, especially in light of fast flux attacks that take use of domain name systems (DNS) with malevolent intent. This project presents a comprehensive architecture that improves DNS security procedures by utilizing the immutability and decentralization of blockchain technology. The core component of the system is a detection mechanism that carefully watches network traffic in order to spot possible security lapses that could be signs of rapid flux activity. This technique is intended to go through large datasets, identifying unusual activity and precisely cataloguing IP addresses that are implicated. The framework then makes use of a blockchain-based ledger system to safely store and confirm the accuracy of the IP data that has been flagged. By taking use of the blockchain's resistance to manipulation, this module guarantees a trustworthy database of compromised nodes that can be consulted for confirmation and future use. The technique represents a major improvement in network security measures since it can keep an incorruptible record of DNS attacks. The last part of the system consists of a DNS modification protocol that operates on the data that is kept on the blockchain. By methodically preventing communication from the malicious IPs that have been logged, it reduces the possibility of quick flux attacks. This proactive measure not only neutralizes the current threat but also acts as a warning to others not to attempt the same vulnerability in the future. By integrating this tripartite system, a proactive approach to cybersecurity is demonstrated, guaranteeing that strong defences are in place to fend off the constantly changing DNS-based cyber threat scenario.
