HTTP flood attack detection in application layer using machine learning metrics and bio inspired bat algorithm

The internet network is mostly victimized to the Distributed Denial of Service (DDOS) attack, which is one that intentionally occupies the computing resources and bandwidth in order to deny that services to potential users. The attack scenario is to flood the packets immensely. If the attack source is single, then the attack is referred as denial of service (DOS) and if attack is sourced from divergent servers, then it is referred as DDOS. Over a decade many of the researchers considered the detection and prevention of DDOS attack as research objective and succeeded to deliver few significant DDOS detection and prevention strategies. How fast and early detection of DDOS attack is done in streaming network transactions is still a significant research objective in present level of internet usage. Unfortunately the current benchmarking DDOS attack detection strategies are failing to justify the objective called “fast and early detection of DDOS attack”. In order to this, in this paper we devised a Bio-Inspired Anomaly based application layer DDoS attack (App-DDOS Attack) detection that is in the aim of achieving fast and early detection. The proposed model is a bio-inspired bat algorithm that used to achieve the fast and early detection of the App-DDOS by HTTP flood. The experiments were carried out on bench marking CAIDA dataset and the results delivered are boosting the significance of the proposed model to achieve the objective of the paper.
