DNSSEC – What Is It and Why Is It Important?

DNS data for a domain is called a zone. Some organizations operate their own name servers to publish their zones, but usually organizations outsource this function to third parties. There are different types of organizations that host DNS zones on behalf of others, including registrars, registries, web hosting companies, network server providers, just to name a few.

DNS by itself is not secure

DNS was designed in the 1980s when the Internet was much smaller, and security was not a primary consideration in its design. As a result, when a recursive resolver sends a query to an authoritative name server, the resolver has no way to verify the authenticity of the response.
