.Gov domain gets security boost

The federal government has deployed a new authentication mechanism for the Internet's Domain Name System, according to a report by Network World.

All federal agencies are deploying DNS Security Extensions (DNSSEC) on the .gov top-level domain to ensure that every federal government Web page is being served up by the appropriate agency, Network World said.

The original DNS specifications were finalized by 1983 in Internet Engineering Task Force RFC 882 and RFC 883. These have since been revised and replaced. Four Berkeley students created the first Unix implementation of DNS in 1984, which became the Berkeley Internet Name Domain (BIND) in 1985. This has become one of the most widely deployed name servers.

The DNS Security Extensions (DNSsec) are a response to vulnerabilities in DNS that make it possible for hackers to provide false information to a request, thus misinforming and misdirecting a client. The initial specification was published in 1997 and was replaced in 1999 with IETF RFC 2535. Further refinements have since been added.
