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.

On the one hand, the core components of the network infrastructure have never changed in the past ten years, which makes some discovered and exploited vulnerabilities and some mature attack tools have a long life cycle and are still valid even today. On the other hand, the rapid development of the application of the Internet seven-layer model has diversified the attack targets of DDoS. From the web to DNS, from the three-layer network to the seven-layer application, from the protocol stack to the application App, the endless new products have also given hackers more opportunities and breakthrough points. Moreover, DDoS protection is a project with unequal technology and cost. Often, the construction cost of a business's DDoS defense system is larger than the cost or benefit of the business itself, which makes many start-up companies or small Internet companies unwilling to make more investment.
