DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.Which chains can use the rules in the raw table: PREROUTING, OUTPUT《即刻电音》是一档原创电音竞技节目，将邀请全球优秀电子音乐人参与选拨评选，从专业推荐、现场演出、视觉呈现等多个角度，为电音狂热粉和泛大众提供一场中国电子音乐的节目。 该节目将选拔出一批优秀的电音作品和实力音乐人。但就在路小北和肖枫彼此鼓励，逆流而上时，一场意外却悄然而至…When adding a hyperlink to a title, you do not need to enter an address, but you need to select from the title tree below.
