The real limiting factor for a single attacker who uses spoofing attacks is that if these spoofed packets can be traced back to their real addresses in some way, the attacker will be simply defeated. Although the backtracking process requires some time and cooperation between ISPs, it is not impossible. However, it will be more difficult to prevent distributed SYN flooding attacks launched by attackers using the advantage of the number of hosts in the network. As shown in FIG. 3, these host groups can use direct attacks or further let each host use spoofing attacks.

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.
