When businesses embark on cyber security initiatives, one of the things that’s often overlooked is DNS security. Many people forget or simply aren’t aware that a compromised DNS infrastructure (or any critical component of that infrastructure) could potentially lead to considerable downtimes, malware outbreaks, data breaches, and several other forms of cyber incidents.
These things can happen because DNS or the Domain Name System plays a crucial role in almost any user-initiated activity that takes place on the Internet. DNS is in charge of resolving the easily-recognisable names like www.somesite.com or ftp.companyx.com that users enter into their web browsers, email clients, or file transfer clients into the IP addresses (e.g. 220.127.116.11) that computers use to communicate with one another.
