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.Analysis: Similar to question 9, but pay attention to this time?一九一零年，广州城举足轻重的两户人家就此消失，欧震天和马天放就此消失。混乱中，欧家姐妹就此失散。原工部侍郎季博康衣锦还乡，他整顿了欧震天原有的资产，创建了“广元行”。广元行的一场劫匪案引出了十六年前三家人的江湖恩怨。侦探司徒雪和天泰商行马若岚在这场案子中终于认出彼此就是失散多年的欧家姐妹。 　　偶然性与性格，往往是决定命运的两个关键要素，而这里有两个幸运的女人，她们将在相遇之后的24小时之内，同时收获爱情和读懂生活……故事发生在1939年的伦敦，基内维尔·贝蒂格鲁小姐是一个人到中年的女家庭教师，可惜她刻板的为人之道，使得她一而再、再而三地被解雇。于是，贝蒂格鲁小姐突然意识到，也许是时候应该走出循规蹈矩的生活了。 　　贝蒂格鲁小姐拦截下来一封本不属于她的职业推荐信，拿着它抵达一处高级公寓去面试“社交秘书”--也就是负责打理日常事务的助理工作。直到见到她的雇主，贝蒂格鲁小姐才发现，自己竟然闯进了一个让人目眩神迷的花花世界，而这一切，都是围绕着她服务的对象，歌坛、影坛双栖的明星黛莉西娅·拉弗塞而展开的。 　　贝蒂格鲁小姐牢记自己“社交秘书”的身份，帮助她的新朋友黛莉西娅打理着已经一团糟的生活，包括爱情和事业……虽然只有24小时，可是贝蒂格鲁小姐和黛莉西娅却在彼此的扶持下，找到了她们命定的归宿。她故意做男娃子打扮的。
