The main reason why DDOS attacks are difficult to defend is that there are too many vulnerabilities and attack methods that can be exploited. In the OSI seven-layer network model used in the network data transmission process, basically each layer has protocols that can be exploited by DDOS attacks. According to the different network levels of the protocols used for DDOS attacks, this paper summarizes the currently known DDOS attack types and their defense measures as shown in Table 1-3.

It was built under the leadership of Chief Cai Xiang and completed in six years. It is a famous beam-type stone bridge in ancient China. Because the bridge is built at the junction of the river and the sea, the river is wide and the water is deep, and the project is arduous, the bridge builder pioneered the "raft foundation" to build piers and planted oysters to fix the bridge foundation, which is an important scientific innovation in ancient China. This bridge, together with Lugou Bridge, Zhao Zhouqiao and Guangji Bridge, is called "China's Four Ancient Bridges". At present, the bridge is 834 meters long and 7 meters wide. There are still 46 boat-shaped piers. There are many inscriptions in the vicinity of the pavilion in the middle of the bridge. There are Song Dynasty cliff carvings such as "An Lan of All Ages" and stone pagodas and samurai statues. There are Zhaohui Temple, Zhenshen Temple and other sites in the north of the bridge, Cai Xiang Temple in the south of the bridge, and Song Monument in Cai Xiang's Wan'an Bridge. In 1988, it was listed as a national key cultural relic protection unit and is one of Quanzhou's scenic spots to declare world cultural heritage.
