Domain Name System Security Extension (DNSSEC).

Domain Name System Security Extension (DNSSEC)

DNSSEC is a group of different protocols and specifications for adding a security layer to the Domain Name System and all its processes. From the look-ups to all the exchange of data.

Those extensions supply DNS resolvers security through authenticated denial of existence, cryptographic authentication of DNS information, and information integrity.

It was created by the Internet Engineering Task Force (IETF). Mainly because the Domain Name System’s design originally didn’t include security aspects. In the early times of its use, different vulnerabilities were detected. Then this DNSSEC was developed. Creators chose to give this system the shape of extensions to make it easier to add them to the rest of the DNS infrastructure already in use.
