Let's talk about rules. Rules are actually predefined conditions for network administrators. Rules are generally defined as "if the packet header meets such conditions, this packet will be processed in this way". The rules are stored in the packet filtering table in kernel space, specifying the source address, destination address, transport protocol (such as TCP, UDP, ICMP), service type (such as HTTP, FTP, and SMTP), and so on. When packets match the rule, iptables processes these packets according to the methods defined by the rule, such as accept, reject and drop. The main task of configuring a firewall is to add, modify, and delete these rules.This part of the confession really makes people want to die. . . . .小葱急忙跪下谢恩。The code for creating the object is encapsulated and the specific factory class is instantiated, thus achieving the purpose of encapsulation and instantiation. Encapsulating the code that creates the object in one place can also achieve the purpose of reuse and is more convenient for later maintenance. This also means that when the customer instantiates the object, he will only rely on the interface and not on the specific implementation. Help us to better achieve interface programming rather than implementation, making the code more flexible to cope with future extensions.
