DNS. A necessary mechanism that makes global network communications work, connecting services to the internet or private network, thereby powering our digital lives can also present confounding and problematic engineering challenges with cybersecurity implications. Site not responding, nefarious applications, applications not resolving, broken network connectivity…many initial responses are Is it DNS? it’s DNS, “It’s always DNS”.
DNS, the domain name system, connects domain names to IP addresses that locate and route information and traffic from a source location to a client can be the bane of many network and cybersecurity engineers as they maintain networks or investigate potential threats on the network.
We’ll look at this critical network component, its threat value and how you can make DNS an actionable component
