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.　　身负重伤的王小龙因未能抛开心中的枷锁而不愿踏进The main reason why DDOS attacks are difficult to defend is that there are too many vulnerabilities and attack methods that can be exploited. In the OSI seven-layer network model used in the network data transmission process, basically each layer has protocols that can be exploited by DDOS attacks. According to the different network levels of the protocols used for DDOS attacks, this paper summarizes the currently known DDOS attack types and their defense measures as shown in Table 1-3. For more detailed information on current DDOS attack and defense, please refer to Huawei DDOS attack and defense summary post.
