Health Evaluation of a Domain Name System Based on the Analytic Hierarchy Process

Abstract

As the vital infrastructure of the Internet, the Domain Name System (DNS) is important from any aspect of Internet actors with the explosive increases of connected things and deployed applications. However, how to monitor and evaluate the healthy state of the DNS is an emergent and difficult issue. In this paper, we propose an Analytic Hierarchy Process (AHP) based DNS evaluation method. We adopt the Point of View (PoV) idea proposed by Global Cyber Security Center (GCSEC) and extend their metric sets for more comprehensive understanding of the DNS health. The AHP is introduced to set the weights for different metrics based on the threat scenario or special PoV. We introduce a monitoring platform with two examples of the actual procedure. The results show that we can adopt this method in any use case for the DNS health evaluation and improvement.
