过了一日，黄豆逃学了。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.Of course, I will also be led astray by some butterflies.In other words, users in BIO are most concerned about "I want to read", users in NIO are most concerned about "I can read", and users in AIO model need to pay more attention to "finished reading".反正，从来跟她打交道的人，最后都被她收拾了。他按捺住激动的心情，高举双臂，用力往下压，众军顿时安静下来。
