How Do You Defend the DNS Infrastructure?
What is DNS?
The DNS (Domain Name System) protocol is a critical part of the Internet’s control plane, providing name resolution functionality and supporting other capabilities that are taken for granted such as load-balancing and internet traffic management. The availability of DNS is key for anyone providing services or content across the Internet. If the DNS infrastructure is unavailable or slow, the user experience would be impacted to the point of receiving a “no internet service” error message.
