The Domain Name System, the DNS, is the internet’s heart. It is a well-known internet service.
It is just like a phonebook your system uses to record hostnames to IP addresses to interact with public services like websites.
Although DNS do not gain much attention, it plays an essential and vital role in online running business like websites, online services, cloud connections, and app. When DNS gets failed so, it won’t show you online. Your business remains down like in a data breach for all purposes and intentions.
The DNS server patterns, which lack proper security style, sometimes lead to severe problems. Attackers can exploit their systems to carry out criminal activities such as transferring DNS zones, altering DNS resolvers to report to various IP addresses to trick people, redirecting websites and email traffic, and introducing DNS amplifying attacks between other types of attacks.
When such things happen, website visitors do not have any way to recognize whether their traffic has been redirected to other servers or not. Moreover, their emails are sent to servers other than the attacked domain’s original servers. For this reason, it is vital to keep your DNS server secure.
