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.该片讲述了一个由一把唐朝古琴“玉香散”引发的“局中还有局，谜里又是谜”的有趣故事。“寻回者”牧云野与端木公平二人以负责为委托者寻回为生，在完成豹子强寻回翡翠玉佩的任务后，陆续接到与之相关的任务，一个巨大的谜团在他们面前展开。另一面，身手高强的路星船与女黑客沙莎为了古琴接近徐远，不料徐远被人谋害身亡。作为徐远的老友，牧云野与路星船联手，在经历一系列冒险之后，三人逐渐接近真相。鞍马天狗，谜一样的人物2012年夏天，历史系学生小浩来故宫博物院实习，在修复文物时遇见了失忆的古装少女明媚，明媚飘忽不定，以为自己是鬼，小浩为了帮她寻找身世，开始展开调查，在调查过程中二人发现了三百年前的深宫谋杀案，发现了穿越之谜，发现了雍正的秘密恋情，唯独对明媚的身世没有帮助，这时二人产生出爱情的火花，小浩不想明媚离开，遂故意毁掉资料，二人产生隔阂。小浩发现科学院收藏了明媚冰在冰里的身体，因为还有生命的迹象，却始终无法醒来，科学院决定将她安乐死，小浩决定要救下明媚，于是展开了一场别开生面的战斗战马飞快的速度带来了强大的冲击，刚刚组织起来的防线一瞬间就被冲垮了。当青少年在高速公路上失控时，雅典娜（Athena）寻求118的帮助。 例行交通站点发现了一个令人震惊的绑架事件； 巴克在康复中挣扎。　　林冲发配后，高衙内不肯放过贞娘，意欲强娶，贞娘不从，自刎。林冲被发往草料场看管草料，陆谦赶来烧掉草料场，谋害林冲。不料林冲因避风雪，留宿山神庙，幸免一死。待陆谦来到庙前。林冲遂将陆刺死。在走投无路的情况下，林教头终于上了梁山。
