Comparable studies of Dos defense mechanism

Abstract

Today, hacking attacks have affected countless Internet companies and users. Especially DDos attacks. Such attacks are long-lasting and cheap to launch. Currently, such defense mechanisms are not perfect, so DDos attacks have become one of the biggest threats to the global Internet environment. In response to this situation, researchers have proposed some new DDos defense mechanisms to make up for the previous vacancy. Through the experiments of the researchers, it was concluded that the performance of the newly proposed algorithm and mechanism was better than that of the previous ones. In addition, the researchers also proposed solutions based on human solvers to bypass the captcha problem. According to the research objects and research methods, this paper analyzes and classifies the collected relevant literature, aiming at summarizing and discovering possible innovation points. The experimental analyzes and reports of these literatures are then provided. In the final part of this survey, we summarize all the literature and propose research directions and recommendations.
