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.TOP集团的长孙、帅哥栋奎亲自驱车探访济安李氏宗家花安堂的真面目。哦，真是该死，怎么不溜神把骑车的人挤下了马路？嗬，竟是一位身着韩服、裙裾飘飘的美丽小姐，情窦初开的栋奎砰然心动。接下来的事让栋奎大跌眼镜，这位看起来古怪精灵的女孩竟然是他要找的花安堂的主人、宗家小姐李秀荷！怎么办？会长爷爷有话：拿到花安堂的孙子才可以接管TOP集团。对于两耳不闻窗外事，一心只学经营术的栋奎来说，接掌TOP集团具有不可抵挡的诱惑力。栋奎决定无论如何一定把花安堂拿到手！爷爷何以对花安堂情有独钟？原来会长大人50年前只是花安堂的区区一长工，一个月黑风高的夜晚，他赶着驮了一袋大米的老牛从花安堂逃出，后来才有了今天的叱咤风云。昔日辉煌的宗家花安堂虽然看上去依旧宏大威严，其实已日趋破落。不过它可是秀荷心目中的宝贝，卖它？绝对不可以！饱受传统教育的秀荷也并不甘心只做花安堂守护者，她要到大都市闯闯天下。谁说都市里只适合红男绿女？秀荷带着乡间的淳朴、挟着传统的威力，在现代的都市里横冲直撞，竟也所向披靡……这不？TOP集团的另1861年，Johnnie Gray是西部大西洋火车公司的一名员工，深爱着他的火车“将军号”，还有他的未婚妻。南北战争爆发了，他的未婚妻让他去从军，军方却拒绝了他，认为让他开火车更有价值。他的未婚妻很生气，发誓除非看见他穿军装的样子，不然再也不和他说话。北军正在计划一个阴谋，准备劫走“将军号”，给南军来一次突袭。Johnnie发现了北军的诡计，更意外的在北军的阵营里解救了他的未婚妻。他必须将北军要突袭的情报带回南军的阵地，他一路上驾驶着“将军号”，遭遇重重追击。南北军大战一触即发......Cpu = new CPU ();
