Dynamic Approach to Defend Against Distributed Denial of Service Attacks Using an Adaptive Spin Lock Rate Control Mechanism
The frequency, severity and sophistication of Distributed Denial of Service (DDoS) attack pose a serious threat to the availability of evolving Internet services. DDoS attack is an incident in which a user or organization is deprived of the services of a resource the people would normally expect to have. They are capable of either crashing the host such that it cannot communicate properly with the rest of the network or disrupting/degrading the host's service and rendering it unavailable for legitimate users. The key feature of DDoS includes distributing the attack across several hosts and coordinating the attack among the hosts.
