DNSSEC is a security protocol that provides an additional line of protection and authentication to prevent potential cyber attacks and fraud within the domain.What is DNSSEC and how does it work?
How DNSSEC Works. The domain name system (DNS) is the phone book of the Internet: it tells computers where to send and retrieve information. Unfortunately, it also accepts any address given to it, no questions asked. Email servers use DNS to route their messages, which means they're vulnerable to security issues in the DNS infrastructure.
