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.『夜叉』是改编自深受欢迎的日本漫画家-吉田秋生之最新原作。主角有末静是位遗传基因受改良，无论在体能、智能的发展都相当惊人的天才。受聘于美国某着名科学研究所。故事的展开从有末静为了调查一桩发生在日本某小岛的病毒感染事件，来到日本开始。龄化问题及生化科技等国际性热门话题；其间并交织主角有末静与其双胞胎弟弟的爱恨情仇。除了故事内容，本剧的映像画面也深受注目。想知道运动神经及身体能量异于常人三倍的有末静，将如何表现其过人之处？而最新人气偶象伊藤英明如又如何展现其精湛演技？Link: https://pan.baidu.com/s/1gggerkv Password: v2l6　　有一天，与初创企业的氛围完全不相似的中年上班族·小鸟智志（西岛秀俊 饰）跳槽到了她身边。随着年龄相差一轮的小鸟的跳槽，佐奈所处的环境发生了巨大变化。Stance sells socks, but a sock brand is loved by many stars and trendy brands, and many sports brands cooperate with Stance.
