DoS outbreaks stand single of the maximum difficult security issues happening today's net besides pose a serious danger to websites. A DDoS assault may quickly and effectively deplete the computational and communication capabilities of its target with little to no prior notice. In order to defend against DDoS assaults, we will build a defence system and secure accessibility of services for authorised customers. The project's objective is to organise the current system attack and protective factors so that more effective defence strategies can be developed and DDoS assaults can be better understood. To prevent a DDoS assault, we will use this approach to shuffle clients across proxy sites continually.
