It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.　　这些青少年心地都很善良，都有个共同点：家庭不健全，心灵空虚。他们包括有个望子成龙的爸爸的凌浩才（翁家鸿饰演）、富商私生女苏美凤（陈碧凤饰演）、鱼贩少东谢阿宝（段伟明饰演）、极度自卑的N水准学生张小花（杨莉冰饰演）、新潮少女麦当娜（郑宛玲饰演）。In order to construct a large number of data streams, hackers often need to construct request data through specific tools. These data packets do not have some behaviors and characteristics of normal users. In order to resist this kind of attack, we can analyze massive data, then model legitimate users, and use these fingerprint features, such as Http model features, data sources, request sources, etc., to effectively filter the white list of request sources, thus realizing accurate cleaning of DDoS traffic.
