When the client SYN packet arrives at the filter gateway, the SYN agent does not forward the SYN packet, but actively replies the SYN/ACK packet to the client in the name of the server. If the client's ACK packet is received, it indicates that this is normal access. At this time, the firewall sends the ACK packet to the server and completes three handshakes. The SYN agent actually replaces the server to deal with SYN attacks. At this time, the filter gateway itself is required to have strong ability to prevent SYN attacks.

Haff's disease in 2009, Most crayfish farmers lost all their money that year, With fewer farmers and fewer wild ones, From 2011 to 2013, the price rose for three consecutive years, and the high price attracted a large number of people to enter. Most of them were inexperienced and had no aquaculture experience. They all heard that crayfish was easy to raise and the price was very high. They thought they could make money, so they plunged in. Most of them did not make money and lost money. I was one of them. About 1996, when I didn't want to go to school, I told my family that I wanted to raise crayfish. As a result, people laughed at me and thought that there were wild crayfish everywhere and there was no need to raise them at all. As a result, after more than 10 years, I finally realized my childhood dream, but I was hit hard for the first time.
Logically speaking. Firewalls can be roughly divided into host firewalls and network firewalls.
In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.
