DNSSEC

The growth of the Internet is due in part to the trust of its users -- trust, for example, that when they type a website address, they will be directed to their intended website. As part of an ongoing effort to increase Internet security and build a safer online environment for users, NTIA (in cooperation with NIST) and its root zone management partners successfully completed the deployment of Domain Name System Security Extensions (DNSSEC) at the Internet's authoritative root zone, which is a critical step towards better protecting Internet users against cache poisoning and other related cyber attacks.

DNSSEC is a suite of Internet Engineering Task Force (IETF) specifications for securing information provided by the Internet's domain name system.
