  DNS Protocol -- Security Feature (DNSSEC)

Category: PROTOCOLS      

Application: DNS Protocol      

The Domain Name System Security Extensions (DNSSEC) is a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by the Domain Name System (DNS) as used on Internet Protocol (IP) networks. It is a set of extensions to DNS which provide to DNS clients (resolvers) cryptographic authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality.

This SonicWALL signature identifies legitimate DNSSEC traffic.
