In this environment, silence has almost become an act of assisting in crimes. Therefore, although CSO people adopt a "non-violent and non-cooperative" attitude towards sharing information, we still try to collect some information through some insider meetings and interviews to understand how security experts originally helped these victimized enterprises to build defense mechanisms. In this way, we have summed up the following tips for readers and friends to deal with DDoS attacks.
SYN attack is a kind of DOS attack. 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.

The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.
