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.2018-01-08 13:18 South Korea Asia Today-Zhu Chengzhi Reporters1912年广州，清朝灭亡。前清武状元荣德（林嘉华饰）流落广州，落难时幸得顾坚诚（郑嘉颖饰）及妻子欧阳惠兰（杨怡饰）搭救。不料却是引狼入室，荣德不仅恩将仇报，还还得惠兰家破人亡。惠兰独自抚养儿女，一心要报这血海深仇。1936年，苦撑武馆20多年的惠兰（元秋饰），几经周折终于与失散多年的长子顾汝章（郑嘉颖饰）团聚。汝章回家后才得知二弟顾汝棠(马国明)身患重疾，以及与荣家的世仇。汝章本无心学武，但一次遇上荣德跋扈嚣张的儿子荣万钧(向佐)而大打出手，才让大家发现汝章是习武之材。惠兰祈望儿子为武馆重振雄风，为当年的血海深仇讨回公道。
