Domain Names Based on Fault Tree Analysis
Ning Zhang, Jun Le, Hai Yan Xu · Applied Mechanics and Materials · 2014
The success rate of domain name resolution has a direct influence on the service of DNS. Analytical performance of DNS server is the key to measure the satisfaction degree of users when they access to the network. This article establishes the dependence model for the domain name server. In order to get DNS fault model and analytical model, this article uses Fault Tree Analysis theory to describe the relationship of tree basic events and target events of fault tree of dependency. On the basis of fault tree model, dependencies of domain names are qualitative analyzed, including number of sets and element composition of fault model and analytical model. This study provided a theoretical basis for DNS dependencies and technical support for the DNS vulnerability analysis. It has a great importance for domain name system security.
