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.Guo Tuan, secretary of the Party General Branch of Beijing Chaoyang Circular Economy Industrial Park Management Center, said: "Plastic foam mixed with domestic waste will cause coking on our boiler wall during our incineration process. We will have to clear this coking during maintenance, increasing the cost. For example, if our dissolved water wall can be used for 5 years and there is more plastic, the dissolved water wall can be used for 3 years, and the direct cost will average more than 3 million per year.
