The DNS (or the Domain Name System) is a distributed, hierarchical system for mapping domain names to IP addresses. As it plays a critical role in the functioning of the Internet infrastructure, the DNS is often the target of malicious activities.

This course will outline the vulnerabilities of the DNS protocol, as well as introducing ways of protecting DNS queries and the integrity of data.
