MONITORING OF TRAFFIC OVER THE VICTIM UNDER TCP SYN FLOOD IN A LAN

Denial of service attack is a major threat in the network security. The purpose of Denial of service (DoS) attack is to disrupt the services offered by the victim. The most common type of DoS attack is flooding with the network traffic to waste the server’s resoures.TCP SYN flood is a kind of DoS attacks that take advantage of three way handshake of TCP/IP protocol in order to disrupt Internet services. The paper explores what a Denial of Service is and how it functions. A Denial of Service demonstration has been shown with TCP SYN flood and the effects it has on the victim computer. The different parameters are analyzed on the victim system and compared with normal behavior of the network indicates the presence of attack
