Button-Reaction AttackDDOS 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.永平帝认为她是被神龟附体的。　　知名演艺经纪人、单亲母亲、45岁的何念晴最大心愿是为独 生爱女何冰冰找到一位如意郎君，但就在婚礼举办前夕，女儿突然告诉她另有所爱。于是开启了一场旷日持久、笑点不断、泪点频频、花样翻新的母女大战，两位性格各异的年轻男子沈方舟和詹姆斯也闯入了她们的生活，将母女二人裹挟进了激烈而浪漫、挑战世俗的“非一般”爱情世界。四位主角各自的亲朋好友，或宿敌仇冤，也纷纷卷入其中，上演了一幕幕精彩纷呈的婚嫁好戏。The humanoid monster in the former is relatively slow, But the ability to fight is very strong, Not sensitive to puncture attacks, Can resist medium caliber and medium power rifle bullets, In the face of fire, Only when they are completely smashed or their heads are cut off can they be killed.

However, I didn't write a blog, but I soon forgot it and didn't play any role. This time I summed it up in the form of a blog, and found that the effect was still obvious, because through this way of summarizing, I understood it more deeply, remembered it more firmly, and affected my thinking of realizing functions at ordinary times. Therefore, I encourage everyone to sort out what they have learned by taking notes, so that I believe they can understand it more deeply and better. I will write it down all the time and then plan to write a series of WCF articles.其实，对小龙女而言，杨过所说的一切，只是一个故事。
