Since http is based on tcp, You need to complete a three-way handshake to establish a tcp connection before you can start http communication, Therefore, when http flood attacks are carried out, it is not possible to use forged source ip addresses to launch attacks. An attacker will typically use an http proxy server, Not only can the source be hidden from being traced, It also improves attack efficiency-after the attacker connects to the proxy server and sends the request, You can directly disconnect from the proxy server and start connecting to the next proxy server, At this time, the http connection between the proxy server and the target web server is still maintained, and the web server needs to continue to accept and process data. An efficient http flood attack should continuously send http requests for different resources and pages, and request resources that cannot be cached as much as possible (such as keyword search. User-related information, etc.)
We all know that computers have a certain security protection system. Through the security protection system, computers can detect certain abnormal viruses and give reminders and removals. The DDOS attacker achieves its goal by evading this protection system and carrying out a rejection attack on the computer, thus bringing the other computer into its own control.

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.
