Speaking bluntly, the Domain Name System (DNS) is the backbone of today’s big Internet. But such important creation got born without a security system. Without DNS, there’s no Internet, at least not in the comfortable way we know it now. Would you trust the Internet knowing that its backbone operates without security? Well, from here, you have a clue to know why DNSSEC is so beneficial. But we can go deeper!
DNSSEC is how the security extensions to the DNS are named. It means Domain Name System Security Extensions. This group of security solutions was created to authenticate and protect DNS traffic. It’s the security layer of the DNS and the Internet that is needed to work safer. It adds cryptographic signatures to DNS records.
