Registration Format:Chapter VII Supplementary ProvisionsDDOS 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.　　谜团奇案，重重交错；冷血凶徒，幕幕惊心！人在做，天在看！「灭罪铁三角」坚守「邪不胜正，恶不抵善」的信念，誓为死者发声，替生者雪冤！自小随母改嫁、个性独立的寒香结识了潇洒的男人梅元修，正当二人幸福恋爱时，一场车祸从天而降，元修为救寒香脚部残疾，寒香自责难当，毅然为巨额医药费出国打工。在国外寒香与一位叫做李佳怡的寡妇相依，不料对方已患上癌症，临终时李将一笔钱及三岁大的儿子灿灿托付给寒香，让她带回国寻找亲人。寒香怀着沉重的心情回国，梅元修误认为她已结婚生子，二人隔膜愈演愈深。小灿灿的亲叔叔李成康的出现，让寒香措手不及。李成康是自己同母异父妹妹欣纯的恋人，二人对小灿灿的感情就像是夫妻。寒香曾占用家庭资金让欣纯没能上大学，对于妹妹的内疚让她本能地拒绝成康。另一方面，寒香从成康那里得知，四年前自家的兄弟公司出了个内奸，灿灿的父亲被害死，其嫂带着灿灿出国，而自己含冤入狱。亲情爱情，寒香无颜面对；真伪善恶，寒香终是难解难分，更是夹在其中难以做人。对她，所有人形同阴森，站在她背后……海州市公安局长遭遇枪击昏迷不醒，原省公安厅刑侦处处长田丰临危受命，空降海州任代理局长之职，在副局长胡克艰和刑警队长赵梦楠配合下对冉江案展开全面调查。随着调查的深入，新的命案再次发生，海州市经济命脉已然被无形黑手所控制，毒品交易暗潮汹涌，田丰一再遭遇恶势力威胁甚至栽赃陷害，决定开始启动卧底计划……
