SYN Flooding Attack Countermeasures in Next Generation Network

In this paper, the authors propose countermeasures against SYN flooding attack in the Next Generation Network (NGN), Applying a filtering and PSO algorithm to IP packets flowing from internet in to NGN. IP packets are checked and abnormal packets for SYN flooding attack are detected at the internal router, and then filter source IP address by security policy that is set in the firewall. In SYN flooding attack some sources send a large number of TCP segments, without completing the third handshaking step to quickly exhaust connection resources of the under attack system or victim.
