天下风云出我辈，一入江湖岁月催。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.年初你与堂姐回单父省亲去过我家，我认得姐夫小姑娘嗓音清脆，口齿伶俐。君望域古羿国，秦家养子秦问天自幼羸弱，秦府被迫将其送入白府联姻，自小寄人篱下，后白家为攀附皇城叶家悔婚，更欲取秦问天性命，他逃出生天，恰逢皇室巨变，羿王长期重症昏迷，摄政王羿横欲夺权篡位，将忠烈之后秦家被冠以莫须有罪名，满门抄斩，残余秦氏子弟逃于西北之上，秦父等被收押至皇城监牢，而秦问天躲过一劫，并立誓要救出父亲妖拔除奸佞，重整羿国。期间，秦问天结识挚友凡乐、若欢等人，加入武学名派九华门，却意外得知落难太子羿无为正藏于九华门中，秦问天与莫家长孙女莫倾城一同守护羿无为，他睿智机敏，周旋于羿天骄的威逼利诱和爷爷秦昊的腹黑心机之间，跨过诡谲变幻的风云迷雾，每每总能化险为夷，最终辅佐明君羿无为登上皇位，此后秦问天淡泊名利心如止水，与莫倾城一同留在九华门守护羿国。仿佛不愿意再说话，紧闭嘴唇。
