Application layer attacks use more sophisticated mechanisms to achieve hacker targets. Application layer attacks do not use traffic or sessions to flood the network, but slowly deplete resources on the application layer for specific applications/services. Application layer attacks are very effective at low traffic rates. From a protocol point of view, the traffic involved in the attacks may be legitimate. This makes application layer attacks more difficult to detect than other types of DDoS attacks. HTTP flood, DNS dictionary, Slowloris, and so on are examples of application layer attacks.

Recently, I have made a preliminary investigation on DDOS attacks, and have some superficial understanding of the causes of DDOS attacks and their detection and defense mechanisms. This paper focuses on some thoughts on DDOS attacks in metropolitan area network environment under traditional network architecture.
"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.

If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.
