DNS Cloud Security Services Arrive
OpenDNS, which provides a free DNS service for consumers and schools, is offering a subscription-based commercial service for enterprises. Other vendors, such as Nominum, are considering offering secure DNS cloud services, as well.
"One of the more troubling experiences from the DNS patching effort was realizing how many organizations didn't even know what DNS servers they were using internally. Recursive name servers tend to just 'run themselves,' only getting noticed when they either have to be patched, or when load exceeds some magic query per second level, at which point random things start breaking everywhere," says Kaminsky, who is director of penetration testing for IOActive. "Running DNS out of the cloud isn't a bad way around this -- the data is effectively public anyway, patching is guaranteed, and you know there's capacity to burn."
