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.A hardware firewall can be set up in front of the Web server to specifically filter requests. This effect is the best, but the price is also the most expensive.而且在这段时间内，汉军元帅韩信还趁机率军征讨河东西魏国，已经取得了很不错的战果，单单从这些方面来说，汉国已经收获不菲了。Rich learning content and resources讲述了面对着因时代的悲剧错误而造成的家族史痛苦，情比血浓的母女三人，却又发生着让人心碎的成长故事
