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.该剧讲述能看到死之前的瞬间的预言家，和重案组刑警，被卷入可疑的连锁杀人案之后，揭开隐藏的秘密的故事。该节目比传统刑事案件报道更有情节性和悬念性。《CSI》的专职顾问伊丽莎白·德瓦恩是一位曾在洛杉矶安全部门供职长达15年的犯罪现场调查人。该节目收视率之所以居高不下，41岁的德瓦恩功不可没。另外，《CSI》已成为美国警方的必备学习教材，连英国苏格兰场、日本警卫厅以及法国警局都视之为反恐教材。该影片讲述了60至90年代四代音乐人追梦的故事。酒吧驻唱歌手兰佳佳和四个不同年代的男人在音乐的指引下聚到了一起，他们共同经历了兄弟酒吧的兴衰沉浮和人生的悲欢离合后，最终解开了心结并且帮助死去的阿布完成了音乐梦想。本剧围绕四名共同生活上百年的吸血鬼展开，第二季中他们将继续努力在当代美国找寻自我方向，啼笑皆非地面对人类超级碗派对、网络暴民、新晋加官恋权的精力吸血鬼，以及所有自在游荡于纽约都会区的幽灵、女巫、招魂师、僵尸和潜行刺客。王管家听了这话，越觉得这个香儿不错。
