Contemporary security systems attempt to provide protection against distributed denial-of-service (DDoS) attacks; however, they mostly use a variety of computing and hardware resources for load distribution and request delays. As a result, ordinary users and website visitors experience timeouts, captchas, and low-speed connections. In this paper, we propose a highly inventive multilayer system for protection against DDoS in the cloud that utilizes Threat Intelligence techniques and a proactive approach to detect traffic behavior anomalies. The first layer of the model analyzes the source IP address in the header of incoming traffic packets and the second layer analyzes the speed of requests and calculates the threshold of the attack speed. If an attack remains undetected, the incoming traffic packets are analyzed against the behavior patterns in the third layer. The fourth layer reduces the traffic load by dispatching the traffic to the proxy, if required, and the fifth layer establishes the need for port hopping between the proxy and the target website if the attack targets a specific web-application. A series of experiments were performed and the results demonstrate that this multilayer approach can detect and mitigate DDoS attacks from a variety of known and unknown sources.
