The US Government has digitally signed the .gov gTLD the General Services Administration has announced.
“On Feb. 28, 2009, DNSSEC became operational on .gov after the program successfully completed all required DNSSEC testing,”
“The .gov DNSSEC public key was registered [Feb. 28] with the Internet Assigned Numbers Authority (IANA) Interim Trust Anchor Repository (iTAR) and became available for use as the published trust anchor for .gov validation,”
“The .gov Top Level Domain is now considered an active DNSSEC signed zone.”
The next step in the government wide effort to better secure its DNS is for agencies to begin deploying DNSSEC within their second-level domains, such as gsa.gov, by the end of the year.
