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.NBC宣布一口气续订《#芝加哥警署# Chicago P.D.》三季。[Illustration: Clean and jerk snatch narrow pull high turn down squat turn by force push high grasp support squat overhang turn] Original　　苔玲在那干的很努力也很开心，每次做完以后都要在显眼的地方留一张字条再出来。 　　启柱回到家常常看到字条，但从未放在心上。苔玲在启柱家做的很开心，启柱不在的时候就像在自己家里一样洗澡、听音乐。回到家的苔玲因为交不起房租被房东赶了出来……
