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.

Located in Shuikou Town, Dehua County, it is mainly composed of Daixian Waterfall, known as the "First Waterfall in East China", gentle oil spill sacrifice waterfall and the mountains and waters along the way. It is a rare eco-tourism scenic spot. Up the Chishi Creek, the natural wonders along the way, which are rippling, covered with thick shade, verdant trees, vines, deep and secluded, birds singing in the valley and peaks swinging back and forth, constitute a unique primitive ecological secluded environment. Oil leaks to waterfalls, and streams gurgle down cliffs more than 110 meters wide like knives, sparkling, spraying beads and splashing jade, just like silver blankets made of tens of millions of broken strings of pearls, which are lightly spread and inlaid on the cliffs. At Daixian Waterfall, the stream plummeted 139 meters down from the steep peak of the mountain. Clouds turned over and snow poured down. It was thunderous and spectacular. Standing under the waterfall, the smoke was steaming and confusing. If it is sunny, the rainbow in front of the waterfall is like an overpass flying in the air, which is very beautiful. At the top right of Daixian Waterfall is a Feixian Pavilion, which tells the beautiful story of fairies showing their saints and saving the people. Looking at the head by the railing, facing the abyss below, Dai Xian's double waterfalls set off on the left and right sides, with no momentum.
