DNSSEC (short for DNS Security Extensions) adds security to the Domain Name System.

DNSSEC allows users to have more confidence in the online activities that are increasingly becoming a part of our lives at work, home, and school.

Here’s how:

The Domain Name System (DNS) is a global database that translates domain names (such as www.internetsociety.org) to Internet addresses that are used by computers to talk to each other.

DNS also provides other information about domain names, such as mail services.

DNSSEC, however, acts like tamper-proof packaging for domain name data. For example, it ensures that a website name typed into a browser delivers the intended server IP address.

Because it's open, DNSSEC also provides us with a platform for future innovations to further enhance user confidence in Internet-based services.

DNSSEC technology used today is the result of careful protocol engineering and standardisation within the Internet Engineering Task Force (IETF), the premier Internet standards body in the world; implementation by various DNS vendors; and operational trials by DNS operators.

We Focus On:

Together with leaders from across the Internet community we are actively engaged in work to drive the broad deployment of DNSSEC and other standards for continuous improvements in Internet security.
