Abstract: - Denial of service attacks prevents legitimate users from using a service. One particular type of this attack is known as SYN flood, where external hosts attempt to overwhelm the server machine by sending a constant stream of TCP connection request. There are several approaches for dealing with this attack that firewall is one of them. In this paper we attempt to prevent this type of attacks with iptables firewalls. Any Firewall prevents unauthorized use and access to your device, its job is to carefully analyze data entering and exiting the device based on user configurations and ignore information that comes from suspicious locations. The firewalls available in the market are general purpose and not suitable to the Embedded boards. Hence I developed and implemented a firewall for an ARM9 processor which uses Linux as the operating system. The Firewall design used Net filters concept in Linux for an ARM9 processor. After implementing the firewall, experimentation was done to study the extent to which the firewall can prevent the securing attacks especially SYN flood attack. Packet filtering concept is used to examine the header of a packet to determine the source and the destination. This information is compared to a set of predefined or user-created rules that determine whether the packet is to be forwarded or dropped. Hence it is established in this paper by implementing the firewall based on Iptables rules one can avoid SYN flood attacks from ARM Board
