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.将步入30岁杜拉拉正式成为公司代理人力资源总监，事业蒸蒸日上，杜拉拉也希望能早日跟王伟结婚。离开公司后的王伟事业发展并不顺利，他对娶杜拉拉始终下不了决心，两人感情渐亮红灯。正当王伟决定自主创业时，事业又遭遇重大挫折，他突然离开上海，不知去向。面对王伟的离去和工作上的纷纷扰扰，杜拉拉陷入绝望。正在此时王伟的同学，也是老对手陈丰横空出世，不但接替了王伟在留下的空缺，也试图添补王伟在杜拉拉心中留下的空缺。王伟并没有彻底离开，受聘于著名民企东源公司后，以一种全新的姿态出现在杜拉拉面前。王伟率领东源公司开始了收购了世界500强公司的大手笔。面对重新崛起的王伟，杜拉拉意识到自己依然爱着王伟。陈丰黯然退出。一番波折后的杜拉拉被任命为东源公司的人力资源总监，和王伟也步入了婚姻殿堂。　　剧集讲述了十二个关于爱、欲望与孤独的故事。比如一个疯子宣称通过一个小盒子创造出了人类文明，苦闷孤独的人在“眼泪森林”中寻找自我救赎，一个漫画家突然与一名杀人凶手共享了视线，一个得了“无聊”绝症的患者到底如何求生。这是一部关于希望与治愈的迷你剧集。官方剧照(9张)　　本片根据取材自光州事件的韩国同名网络漫画改编。不过非说他霸占民田，也聊得过去。
