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.新上任的小学女教员芳贺稻子（吉濑美智子 饰）现年35岁，拥有10年的教龄，可谓经验丰富，人称“钢之女”。任职于爱河小学的稻子被委托教导四年三班。这个看似普通的班级却先后让三任班主任辞职离去，而辞职的原因却不明。表面上天真无邪的四年三班的小朋友们，背地里到底做了什么，让大人们摇头离去。稻子带着疑惑开始了和这群小朋友及他们背后的家长的战斗。However, under the circumstances at that time, I thought these things had little effect, because after we knocked them out, we began to gather in more quantities and launched attacks on positions from all directions.
