According to CNCERT sampling monitoring data, this month's DDoS attacks including cross-domain forged traffic are counted by province, with Jilin Province having the largest number of incidents, followed by Heilongjiang Province, Liaoning Province and Hebei Province. Compared with the cross-domain counterfeit traffic attacks in various provinces in December 2017, Beijing has the largest decrease in the number of incidents this month, followed by Guizhou, Guangdong and Zhejiang provinces, as shown in Figure 28. As can be seen from the figure, the governance effect this month is relatively obvious, and the number of cross-domain forgery traffic incidents issued by most provinces has been greatly reduced, as shown in Figure 25.

From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed. Let's look at the following code:

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).
