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.仅凭这种奇特的开篇，就足以比下无数武侠小说了。2426他自然没法请示胡总督，但请示徐首席也够了。協力者 永作博美 佐戸井けん太CCTV financial reporters clicked on the speed measuring software of a 5G mobile phone and a 4G mobile phone at the same time and found that the download speeds of the two mobile phones were very different.
