The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.所有事件都从血开始！ 为了正义而压抑自己的欲望的吸血鬼检察官闵泰延（延政勋饰）， 以无法停止对血的欲望而活的未知吸血鬼！ 本能地互相认出的两个吸血鬼， 为了自己的欲望和本能开始了互相追逐 无法逆转的命运的对决逐渐展开！现在已经容不得我们组织力量来据守。The above configuration process takes only one time, and then you can happily use the service iptables save command to save iptables rules in centos7.Building.
