How should we defend against this attack? First of all, as users, we try our best to download APP from regular channels and surf the Internet in a civilized manner, and try our best not to make broilers. Secondly, as a service manufacturer, when the server is attacked by DDoS, we try our best to improve the processing capacity of the server. When the processing capacity of our server is greater than that of the attacker, these attacks are nothing to the server. Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.I will try to adjust the parameters according to my understanding of the nature of the data and the theory behind the algorithm. If I cannot explain why the results are getting better or worse, I will find this adjustment strategy unreliable.男主陈重因送红包花光积蓄30万，怒而伙同好友们策划一系列意想不到的“回本”计划，一场由红包引发的喜剧，就此展开了……眼下的马六甲，弗朗机东印度精兵尽出，余下的弗朗机人怕是千人都不足。Baidu Internet Disk https://pan.baidu.com/s/1skZQPcT项庄神色话语间满含羡慕，半晌后问道：此剑有个传说，尹兄可知晓？传说？什么传说？尹旭一片茫然。
