In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).

6. After six months of special treatment of attack resources in China, the monthly active number of resources such as domestic control end and broilers has shown a relatively obvious downward trend compared with 2017. The monthly increase rate and extinction rate of resources such as domestic control end, cross-domain forged traffic source router and local forged traffic source router in the past three months have increased to a certain extent compared with the monthly average value in 2017, which means that the change rate of resources is accelerated and the stability of available resources is reduced. Compared with the monthly average value in 2017, the monthly increase rate and extinction rate of domestic reflection server resources have not changed significantly, and the extinction rate has decreased to a certain extent, which means that the amount of available resources is gradually decreasing.
