It doesn’t normally get a lot of attention, but the DNS (Domain Name System) plays a critical role in the presence of an online business––website, online services, cloud connection and applications. When DNS fails, end users cannot find you online. For all intents and purposes, your business is just as “down” as it would be in a complete data center outage.
This, as one might imagine, makes DNS an attractive target for attackers. Like the security of any other business-critical service, enterprises should take steps to secure the availability and integrity of their DNS deployments.
