Abstract

Cyber security, also referred to as information technology security, focuses on protecting computers, networks, programs and data from unintended or unauthorized access, change or destruction. Governments, military, corporations, financial institutions, hospitals and other businesses collect, process and store a great deal of confidential information on computers and transmit that data across networks to other computers. With the growing volume and sophistication of cyber-attacks, ongoing attention is required to protect sensitive business and personal information, as well as safeguard national security. DDOS type of attack is the serious threat to the nodes in the internet. Various attackers lying in the distributed manner can attack the network so that there will be slow unnecessary requests to the server. Which in results overload the network. In existing research entropy based technique was used. In which delay entropy is calculated for the sample in time interval T. if the entropy value is greater than the threshold value then attacker is assumed. In current research hybrid approach based on PSO and FireFly is used. It identifies the optimal application server where the request can be sent. This optimality is checked based in delay it is producing. This approach has shown positive results. The performance parameters like end to end Delay, packet Delivery Ratio and Throughput has shown improvement. That means hybrid approach considered in current research has shown the improvements.
