DNS SEC
Last modified: Thursday, December 27, 2007 

Short for DNS Security Extensions, DNS SEC is a set of extensions used to add an additional layer of security to the Domain Name System (DNS). DNS SEC was designed to prevent specific types of popular attacks on the Internet and protect against these threats to the Domain Name System. The specific extensions provide origin authentication of DNS data, data integrity and also to authenticate denial of existence. May also be seen written as DNSSEC.
