DEFAD: ensemble classifier for DDOS enabled flood attack defense in distributed network environment

Technological advancements in the information systems and networks are the outcome of potential developments resulting in the networking and communications. The role of Critical Infrastructure is playing a vital role in imparting the condition of effective information systems management. However, with some of the negative developments like DDoS attacks that impact the operations of network application systems, there are adverse set of issues encountered. With the rising number of DDoS attacks phenomenon, researchers have focused on developing contemporary solutions that can support in thwarting such attacks. From the review of such models in the literature review, it is imperative that two distinct dimensions like the detection and mitigation accuracy levels has scope for improvement and profoundly majority of such models were tested on the static datasets which are not pragmatic. Considering such equations, the model proposed in this manuscript focused on a contemporary range of solution that can be high on accuracy rate and also is tested over the dynamic dataset to understand the efficacy of the system. Using the ensemble classifiers comprising drift detection features, at service request stream level, the proposed solution if implemented can lead to better levels of detection. Experimental study of the model carried out using the service request stream that is synthesized is tested based on statistical metrics like accuracy, prediction value and true negative rates. Significance of the model is imperative in terms of results generated and its comparative analysis to the other bench-mark models in the segment.
