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.尹旭却稍微有些为难了，他现在和诸先生谈的正好，有些不大愿意暴露身份，可是这个似乎已经不在自己掌控的范围以内……山坡下，苏岸正在焦急地等待着，他之前接到消息称有盗匪在清溪谷一带，这一带又是越军搜索比较少的地方。《为爱放手》讲述了平面模特李莉（童菲饰）和乐队主唱谭耀（姜潮饰）两个处在迷茫期的年轻人相遇相爱，和一行人面对梦想、爱情、现实时的挣扎与选择。Set horizontal or vertical movement according to your needs.This.parent = parent;
