The Domain Name System (DNS) is a hierarchical decentralised system that assists humans in not needing to memorise long strings of numerical IP addresses. It has become so ubiquitous, that it forms part of critical information infrastructure, and with many businesses relying on its continued stability and security.

This presentation will examine the complex interactions of this system, from domain registration to name resolution, the security risks of each component, and the mitigation options currently available.

This short course provides a good introduction to DNS security, and leads to the more technical course eDNS03: Securing the DNS
