Without back-up, the DNS is also vulnerable to power and network outages. And if the name server doesn’t respond, everything goes with it.
As it is our first week back after the 2016 New Year celebrations, we just couldn’t resist a *punny* blog on DNS resolution. More specifically, on how you can have a well configured authoritative DNS.
It picks up on an article we published in IT World Canada called, “6 things that IT managers should add to their to-do lists for 2016.” In the article, we cite that the Domain Name System (DNS) server is often a forgotten element of cybersecurity. It is set up once by IT administrators and then left alone or outsourced to the best efforts of a hosting company. When it’s working, responding to queries and directing users appropriately, everything is great. But the DNS server is as vulnerable to malicious users as anything else. Without back-up, the DNS is also vulnerable to power and network outages. And if the name server doesn’t respond, everything appears to come crashing down with it.
This is underscored by a study we did that determined only 7% of all over 125,000 DNS servers queried were successful at responding 100% of the time. By our definition, which is perfection, that is a 93% failure rate!

Therefore, we want to ask everyone to make a personal New Year’s “resolve-olution” to help maintain a stronger DNS for your organization that resolves 100% of queries. Now, we know most resolutions are hard to keep and are usually forgotten by mid-January, but the DNS is critical to your web presence. To make it easier, we have created a handy little checklist for DNS managers and IT administrators to keep a rock solid DNS.
We took the list published in IT World Canada a step further and detailed 14 things to do in order to keep a strong DNS. It is a simple pdf, designed to be printed and taped to your cubicle wall or server room to help make it easy and quick for you to complete – join the best DNS in the world list in 2016.
