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.本剧内容以刑警队探长钟保国，老刑警刘玉德和刑警李小光等干警一系列侦破工作为主线，呈现出了公安战线上干警血奋战的感人生涯。在身边熟悉的人暗设的陷阱里，在同事怀疑抵触的行为中，在无知村民的围攻殴打下，在残忍狡诈的强奸犯面前，在追捕毒犯凶险的途上……他们顶住各种压力，历经艰险，勇破一个个案件。最后，他们又如何面对凶狠的歹徒无处不在的枪口……...来港奔丧的高大喜（黎耀祥 饰）经父亲好友推荐进入警队工作，再一次抓赌行动中一颗子弹贯穿大喜头颅，脑细胞被激活进化，他变身智商超人，成了无案不破的神探高伦布。但同时他的情商管理区却逐渐缩小，性情发生了严重变化。在市民眼中他是神探，在匪徒眼里他是克星，但在警队同事眼里，他是一个不近人情的冷血动物。保安司金路易（Joe Junior 饰）急招刚从苏格兰场毕业的女儿金伊娃（马赛 饰）回港，并安排警员蔡飞龙（萧正楠 饰）当其助手，日夜监视大喜行踪。大喜略施小计赢得伊娃芳心，但伊娃同时也对业务出色的飞龙产生仰慕，一时陷入两难之中。当年与大喜悔婚的梅妹（唐诗咏 饰）赴港寻女，得知大喜未婚，决定与他再续前缘......《天涯明月刀》图册范文轩很是自信，言语间有些嘲弄的意味。当一个紧张的时间旅行痴迷的年轻科学家被他虚无主义的未来自我拜访时，他被告知他需要放弃成为世界上第一个时间旅行者的梦想，否则。但当他不同意这个计划时，这就变成了一场人类与自己之间的恶战。亚丁顿教授召结了一群在心理临床领域表现杰出的得意门生，展开一项神秘研究。年仅14岁的117病患小莱，五岁就被送到收容机构与世隔绝，她似乎拥有能预知并操弄人心的神秘力量。因此，研究员们只能透过监视屏幕，远端观看小莱的生活图像，然而，其中一名研究员麦蒂逊开始觉得事情有些不对劲，她发现自己脑海渐渐被小莱的声音盘据，不时出现断片的状况，甚至接连有研究员离奇丧命，且事发时间都与小莱的异常反应时间重叠。随着麦蒂逊锲而不舍地追查，隐藏在单纯研究背后的恐怖真相也将呼之欲出。
