I asked.《莎拉共和国 Republic Of Sarah》讲述一家贪婪的矿业公司正在摧毁小镇，于是叛逆的高校老师Sarah（Stella Baker饰）决定利用制度漏洞并宣布独立，而成功后她得带领一群年轻人从零开始建立新国家。与2006年发售的《Marave Altanative》一起形成了一个壮大的故事，是一个展开了很多Shared世界标题和媒体混合的项目。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.
