Course Description

The Domain Name System, commonly known as DNS, is often referred to as the "phone book" of the Internet. Every time we access the Internet to visit our favorite websites, shop and pay bills online, or access online portals for healthcare or banking, we depend on DNS infrastructure to securely route us to our intended destinations. While this shared infrastructure is incredibly powerful and useful, it also presents a rich attack surface for threat actors: allowing them to shut down websites and online services, replace legitimate website content with threats and extortion attempts, or even route traffic to a carbon copy of a legitimate website to steal any information entered by users intending to conduct business as usual. "Understanding DNS Attacks" provides key information you need to know to protect yourself and your organization from DNS infrastructure tampering including common vulnerabilities, how to identify a potential attack, and guidance and best practices to mitigate the likelihood and impact of a successful DNS attack.
