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.咬紧牙关熬他十来日，也就过去了。末了又道：王爷，不是我刘家爱财——来多少，我们还不照样陪一份回去。田丽君为姐姐的死，前往一小镇找凌世豪决斗泄愤，却听到凌世豪已被刁大娘手下邓石平所杀。 后来，田丽君王霜霜身上找到线索，凌世豪并没有死，他三年一直努力练功月要找刁大娘报仇。 凌世豪与王霜霜摆脱田丽君的纠缠，到达小镇，杀死了仇人邓石平，却不敌刁大娘手下众人，双双被擒，并身受重伤，落入刁大娘手中。 田丽君得到消息，深入虎穴救出凌世豪，并放到一间破庙，欲后再救出王霜霜，却发现不见了凌世豪。 原来之前凌世豪救过一位道士，道士感谢他救命之恩，把先天太极拳法传授给他。 田丽君答应王霜霜与凌世豪一起找刁大娘报仇，再解决本剧翻拍自法剧《百分之十》，由BAFTA获奖编剧John Morton负责，众多英美一线明星客串。聚焦跨大西洋行业关系，还会涉及英国对阶级制度的痴迷等方面。NBC剧集《罪恶黑名单》宣布续订第8季。 该剧也刚庆祝了总第150集开拍，目前播到第7季，下半季将于3月20日回归，本季和第6季的收视都较为稳定，是续订因素之一。
