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.

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.

Developing and Testing an Effective Breach Response Plan
Whether or not a data breach is a disaster for the organization depends on the security team's response and that is based on how the team developed a breach response plan beforehand and if it was thoroughly tested. Inside this report, experts share how to: -understand the technical environment, -determine what types of incidents would trigger the plan, -know which stakeholders need to be notified and how to do so, -develop steps to contain the breach, collect evidence, and initiate recovery.
