Protection of server rom SYN Flood attack

Abstract

Due to advances in Internet Technology applications, the clients at remote places require constant services from a server. Internet services can be denied by malicious attacks on the server. One such attack is SYN flood attack which is a type of DDoS attack. This manuscript demonstrates the protection of server against the SYN flood attack. The algorithm uses a continuous self detecting method for identifying and updating genuine client information in the presence of spoofed packet and thereby protecting the server from SYN flood attack. During this process the algorithm builds the repository of genuine client information. This repository of genuine client can be used by other security systems like IDS, Packet filtering etc. for protecting the server. The performance of SYN flood attack protector can be further improved by implementing this algorithm in hardware such as FPGA.
