-Akiha (Founder of Akiha PPT and Founder of Knowledge IP Training Camp)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.中学教師 稲垣吾郎 村松克巳(3) When the towing length exceeds 200m, a diamond shape is displayed at the most obvious place.　　罗江从接受命令开始，就遇到了一连串的危机。我意是封他为汉、中王，也是秦国故地，也算和怀王之约沾边。
