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.

Similar to the development of children from appearance and color to older children, they can be classified according to concepts. For example, if they know the concept of "food", no matter what kind of vegetables they look like, they should be classified into one category. The classification of biology has also developed in this way. The earliest method is to identify and distinguish species according to phenotypic characteristics, and to classify them step by step according to the degree of phenotypic similarity, so as to establish a classification system that is easy to retrieve. This is the principle of phenotypic classification. However, the problem of phenotypic classification is that it is difficult to reveal the essential laws of things. Many creatures with very different shapes may have kinship relationships. For example, the online sentence "When I knew sunflowers belonged to Compositae, I collapsed" is what it means.
