Review of Mitigating DNS DoS Attacks

The Domain Name system (DNS) has become a ubiquitous part of modern internet infrastructure that maps numeric IP address to human-readable names. In the recent years, denial of service (DoS) attacks on DNS has a trend to be more serious problems. These attack is mainly related the hierarchical namespace architecture, which is hard to avoid as this architecture are widely deployment in multi-level approach. Therefore, researchers tend to solve this problem by changing its structure, configuring the original setting and enhancing the availability by augmenting its low-level DNS resolver. Such researches significantly improve the reliability and availability against that DoS attack. However, as the numerous solutions it has, there does not exist a standard way to achieve this problem. This paper gives a brief overview of DNS service, and review numerous recent researches tend to solve the DoS attack on DNS service.
