Abstract

Transmission Control Protocol Synchronized ( TCP SYN) Flood has become a problem to the network management to maintain the network server from being attacked by the malicious attackers. Possibly one of the problems in detecting SYN Flood is that hosting server nodes or firewalls cannot distinguish the SYN packets of normal TCP connections from your of SYN Flood attack. Moreover, considering that the fee of normal network traffic differentiates, we are unable to work with an explicit threshold of SYN arrival rates out to detect SYN Flood traffic. Taking into consideration time period variant of arrival traffic. We first investigate the status of the arrival rates of both normal TCP SYN packets and SYN Flood attack packets. Our new detection mechanism based on the stats of SYN arrival rates. Our proposed mechanism can detect SYN Flood traffic quickly and precisely despite time variance of the traffic. Experimental results show that the proposed detection method using the combination of packet filtering and syn flood based traffic monitoring can detect TCP SYN Flood in the network and alerts are sent to the administrator through e-mail mechanism. .
