Improved defense against domain name server man-in-the-middle spoofing

摘要

The Domain Name System, or DNS, is an important facility in the Internet.But for some reasons, DNS interaction is quite vulnerable to a kind of man-in-the-middle(MITM) spoofing attack.This paper illustrates the MITM spoofing attack and proposes a type of defense technique employing Naive Bayes(NB) Classifier.Considering three types of individual factors, then illustrates, analyzes and evaluates their performances.The 3-factor NB technique achieves the best performance with an average identifying ratio of 99.7875%.What's more, we provide a proposal on taking balance of precision and time consumption accordingly.In all, the presented NB technique is quite helpful in defense against DNS MITM spoofing attack.
