MITIGATING DDOS ATTACKS USING RANDOM SHUFFLING GREEDY ALGORITHM: A DYNAMIC PROXY-BASED DEFENSE APPROACH

Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks continue to be a major threat tocybersecurity, disrupting network services and causing significant downtime. This study proposes adynamic defense mechanism using a Random Shuffling Greedy Algorithm (RSGA) to counter DDoSattacks. By assigning client requests to proxy servers in a randomized manner, the system introducesunpredictability and effectively hides the application server from attackers. This Moving Target Defense(MTD) strategy ensures improved scalability, real-time attack detection, and resilience, while maintaininguninterrupted services for legitimate users.
