Security Issues with DNS

Author: Florent Carli Published April 14, 2011 from SANS

This document first reviews some basics about how DNS works, then goes into explaining the different ways a hacker can attack the DNS protocol implementation to use it to his own advantage. We will focus on the relationship between all the terms we hear, which are usually misemployed. We will then review the different possible server attacks and finish by explaining some of the ways that should be used to protect against these issues.
