The DNS is the Typhoid Mary of the Internet
Firewalling DNS calls gets half way to solving the major problems with the DNS.  While doing so is a good first step, it does not cure the main exposure the DNS provides to the bad guys. The next step is to move the DNS into an encrypted policy engine where sources are verified before routing is even allowed. In the medical, industrial and other dedicated IoT spaces, the IP addresses are dedicated and persistent, making the DNS an unecessary and dangerous component of routing. While the DNS may always be with us for the public side of the Internet (email, the web, social media, etc.), its use on the commercial and industrial side is no longer viable.  The sooner we elevate the discussion around the wisdom of not using the DNS in the wrong places, the sooner we will get to a more secure Internet.

Re: The DNS is the Typhoid Mary of the Internet
Strongly agree with above post by Gsidman. I would like to echo the author's sentiments - the hardware and labor cost inputs required to implement a simple but effective system are so vastly outweighed by the benefits. Seems to me that that vast majority of intrusions/theft/ransom/dos attacks as well as infrastructure vulnerabilities could be eliminated by such a simple fix. Neither hard nor expensive (relatively speaking) and should be number 1 or 2 on the top of every IT, facility or municipality manager's list.

Re: Pending Review
I would really like to know as well! Seems to be a good idea to get a DNS Firewall!

Everything You Need to Know About DNS Attacks
It's important to understand DNS, potential attacks against it, and the tools and techniques required to defend DNS infrastructure. This report answers all the questions you were afraid to ask. Domain Name Service (DNS) is a critical part of any organization's digital infrastructure, but it's also one of the least understood. DNS is designed to be invisible to business professionals, IT stakeholders, and many security professionals, but DNS's threat surface is large and widely targeted. Attackers are causing a great deal of damage with an array of attacks such as denial of service, DNS cache poisoning, DNS hijackin, DNS tunneling, and DNS dangling. They are using DNS infrastructure to take control of inbound and outbound communications and preventing users from accessing the applications they are looking for. To stop attacks on DNS, security teams need to shore up the organization's security hygiene around DNS infrastructure, implement controls such as DNSSEC, and monitor DNS traffic
