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.PREROUTING, FORWARD, POSTROUTING愈爱药房以福建东山岛的寡妇村为故事原型，讲述1949年仲夏发生在“离岛”上的故事：邱家丫鬟许淑萍被匆匆嫁往离岛不久，一场兵灾就将丈夫王金水和岛上的男人全部抓兵到了台湾，小岛一夜之间成为没有男人的“寡妇村”。淑萍和岛上的女人们一起立誓今世侍奉公婆，给丈夫留一个家。四十个酷暑寒冬，女人们向海神祈祷，日子在没有爱的无穷尽的等待与盼望、希望与失望、诱惑与坚守、奇迹与疯狂中划过。辗转在两岸之间的家书，成为牵系亲情的纽带，也演绎了一段段“家”和“爱”的传奇。Also, you can register multiple delegates for an event with + =.********周耀辉看着板栗面色古怪。
