A Gesture Based Turing Test for Mitigation of DDoS Attacks in Cloud

The attractive features of cloud computing has lead to its widespread adoption in various sectors like healthcare, ecommerce, banking, power, education etc. However, attacks can put the availability of services of such crucial sectors in danger. One of the security concerns is due to Distributed Denial of Service (DDoS) which is one of the deadliest attacks from past years. This paper proposes a novel approach to mitigate DDoS attacks using a Turing test based on gesture verification. By challenging clients with gesture-based captchas, the system aims to differentiate between legitimate users and attacking IoT devices or bots. The performance evaluation of proposed method has been done by considering Yo-Yo attack with synthetically generated traffic. The findings show that the suggested approach demonstrates superior speed and cost-effectiveness compared to other existing state-of-the-art methods, offering a promising solution for safeguarding cloud services.
