Define what DNS monitoring is, explain how hackers commonly attack DNS, and then express your opinion on whether or not you think the monitoring is important and why. If you have any experience in this area, consider providing a real-life example of a time when you've witnessed the implementation and/or use of DNS monitoring.

"DNS monitoring can be used to secure the communication between browser users and the websites and services they use. In my opinion, utilizing DNS monitoring is a good idea because it can help to diagnose issues, prevent attacks, and preemptively identify security breaches. DNS is commonly targeted by hackers; sometimes they insert false information into a company's DNS cache in order to reroute visitors to a spoofed website to collect their private data. Other times, hackers use DoS or DDoS computers to try and crash a company's website with excessive requests. Within my last position, we used DNS monitoring, which means that we regularly checked DNS records for unexpected changes and outages. This helped us to maintain the credibility and safety of our servers, as well as the safety of our users and websites."
