The internet got a little more secure today after global registry VeriSign announced the deployment of DNSSec for the .net domain, the largest yet to become enabled with the security technology.
DNSSec is a key upgrade to the internet designed to protect against man-in-the-middle and other DNS attacks. It involves the digital signing of DNS records using public key cryptography, so they can then be verified to prove their authenticity.
Raynor Dahlquist, senior vice president and general manager of naming services at VeriSign, explained that DNS data associated with .net registrations will now be protected from hackers using cache poisoning to redirect valid user queries to malicious sites.
"There is, however, more work to be done, as ISPs, browser vendors, registrars and other members of the DNS ecosystem confirm that their solutions and services are ready for DNSSec enablement," he said.
"We will continue to work with all of those parties to shepherd a stable deployment of DNSSec, particularly as we prepare to sign the .com zone in Q1 2011."
The announcement follows VeriSign's collaboration with Educause and the US Department of Commerce which led to the deployment of DNSsec for the .edu domain earlier this year. The first top level domain to fully deploy DNSSec was .org in June.
VeriSign has been a strong promoter of DNSSec in the past few months, urging internet firms such as Brocade, Cisco and Juniper Networks to sign up to its Interoperability Lab designed to ensure that all equipment and applications can support the new system.
The company launched a cloud-based DNSSec Signing Service for registrars last week, which allows DNSSec provisions to be added to second-level domain names.
