DNS Security Rollout Begins

(Other stories by Jason Livingood)

"We're pleased to announce that beginning today we will start the process of migrating customers to DNS servers that use Domain Name System Security Extensions (DNSSEC), as part of an evolving suite of security protections that are part of Comcast Constant Guard™. Best of all, customers will not need to take any action and should not notice any changes to their service, though behind-the-scenes that service will be more secure. As the first major Internet Service Provider (ISP) to do so in the United States, our customers are among the first to be getting these new security capabilities, which is part of our continuing push for a more secure Internet experience for both our customers as well as the global Internet.

"With DNSSEC, a web site name such as www.comcast.net can be cryptographically signed in the Domain Name System by the domain name owner. Then, when a customer tries to connect to that website, the Comcast DNS server checks that domain name, and verifies that signature to ensure that it is valid and has not been tampered with by hackers or other criminals. A customer will only be connected if this security verification has been passed, which occurs so quickly our customers won't even notice that it's being done."
