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.

"With the experience of the above two times, I realized it wasn't that simple, For example, I observed these dogs at that time. But it is definitely not a dog's strange thing. Apart from being large in quantity and fast in speed, In addition to a very strong sense of attack, There is still some tactical nature, In the words of my teachers at the military academy, 'Tactical awareness is a further sublimation of basic organization', I feel it is most appropriate to use this word on these strange things. They know that they are surprised and flank while attacking the front. I also assumed that they were trained by the Vietnamese army, but I didn't think of a clue and didn't continue to think about it.
