Distributed Denial of Service (DDoS) attacks are becoming more frequent and the size of these attacks is increasing rapidly on every year. This increases the load on the networks of Internet Service Providers (ISPs) and many Cloud computing providers. Cloud computing is an emerging technology and adopted by many Cloud providers. But, there are many issues and one of them is Distributed Denial of Service (DDOS). Distributed Denial of Service (DDoS) attack is the most prominent attacks in this area of computing. DDoS is the single largest threat to internet and internet of things. The frequency and sophistication of Distributed Denial of Service attacks (DDoS) on the Internet are rapidly increasing. In this paper, it is conducted an up-to-date review of essential Cloud Network threats and present a methodology for evaluation of existing security proposals. Based on this, introduced a comprehensive and up-to-date survey of proposals intended to make the Network Infrastructure highly secure and introducing new methods for detection and mitigation of routing instabilities and these generic countermeasure model can be used to prevent secondary victims and to prevent DDoS attacks. These taxonomies define varies similarities and different patterns in Dos and DDoS attacks, configuration, functional tools, to assist in further improvement on Network Infrastructure security and proposed a solution to countering DDoS attacks.
