摘要：DenialofService (DoS) is a network security problem that poses a serious challenge to trustworthiness of services deployed on the servers. The aim of DoS attacks is to make services unavailable to legitimate users by flooding the victim with legitimatelike requests and current network architectures allow easytolaunch, hardtostop DoS attacks. Nowadays every one relies on online transactions. These transactions involve one of the many types of denial of service attacks is known as TCP SYN Flood attack. The goal of the attacker is exhausts the victim network of resources such as bandwidth, computing power,etc.,the victim is unable to provide services to its legitimate clients and network performance is greatly deteriorated. Defending against those types of attacks is not trivial job, mainly due to the use of IP Spoofing and the destinationbased routing of the Internet. This paper explains about efficient packet filtering technique using firewall to defend TCP SYN Flood attacks. Firewall scripts are written using commandline tool IP Tables in Linux to deny the suspicious traffic.
