If the connection initiator is legal, the firewall/proxy will receive the ACK, then establish a connection between itself and the server and disguise the address of the connection initiator. The firewall/proxy separates the two sides of the connection. This segmentation can resist SYN flooding attacks because the server has not accepted SYN from the attacker at all. As long as the firewall/agent implements some TCP-based defense policies, such as SYN? Cookies or SYN? Cache, he can protect all servers behind him from SYN flooding attacks.
B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).

The data structure of the SYN cache is robust to attackers who attempt to overflow the HASH tablespace. Because its HASH value contains the port number and some password bits of the other party. Because stacks are a more efficient data structure than linked lists, stacks are used for SYN caching to improve speed. In Lemon's test, hosts under active attacks were able to establish connections with SYN cache and were only 15% delayed from normal time.
