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.

We first went to the village committee and obtained the consent of the leaders of the village committee. With their assistance, we arranged a row of tables and stools in the courtyard. Two sphygmomanometers were placed on the table, flyers were posted on the wall, banners were hung and flags were erected. Teacher Zhao informed the villagers to come to the village committee on the radio. After everything was ready, we waited for the villagers to arrive with leaflets, brochures and questionnaires. After the announcement was broadcast, villagers came soon. The students greeted them with smiles, handed out knowledge books to the villagers, explained scientific knowledge to the villagers, and conducted a questionnaire survey. Since most of the villagers could not read, we all asked them one question at a time. It may be easy to do one survey, but it takes great patience to do many. In addition, the villagers generally speak local dialect, and some students have some obstacles in communication, but we have all overcome various difficulties. Some of the students are handing out leaflets, some are answering villagers' questions, some are doing investigations, and some are measuring blood pressure for villagers. The teachers are even more integrated with everyone, and they can no longer tell who is the student and who is the teacher. Gradually, the number of villagers increased, and everyone was even more busy. Look at this lively scene: there are investigations, leaflets, interviews, blood pressure measurements and photos-everyone is really busy! In this way, we successfully completed the task of the first stop.
