DNS Security


 DNSSEC technology standards have been stable and mature since 2007, with only updates, clarifications, and new functionality added since then.

 Some folks have already asked me if DNSSEC could have prevented Twitter.com traffic from being hijacked. In this case, the answer is, "No".

 Over the next few years we should expect to see applications leveraging DNSSEC in ways we cannot imagine now.

 The movement is on, DNSSEC, ready set go! Just make sure you are ready when you go!

Going for Broke: Financial Services Industry Falling Behind on DNSSEC Adoption

Many CircleID readers have been watching the acceleration of DNSSEC adoption by top level domains with great interest, and after many years the promise of a secure and trustworthy naming infrastructure across the generic and country-code domains finally seems within reach. While TLD DNSSEC deployments are major milestones for internet security, securing the top level domains is not the end goal - just a necessary step in the process. more»

The Mailbox That Saved DNSSEC

A very long time ago, back in the ancient time of year 2006, the registry for .se domains, also called .SE, opened up for signing .se zones with DNSSEC. In those days .SE did not have a registrar/registry model and my own company Interlan was then an agent for .SE. One day I suddenly got a mail from .SE regarding secure DNS -- DNSSEC. ...I almost immediately saw the benefits that such a solution could give to a better and more secure Internet. more»

IPv6 Stat Leapfrogs Expectations and Illustrates Important Role Registrars Play in Uptake

Since 2005, Infoblox has commissioned a survey by The Measurement Factory, a research firm that specializes in performance testing and protocol compliance. The studies examine key aspects of the Internet's Domain Name infrastructure with results that uncover trends in DNS server configuration and deployed features. Some topics that have helped define the survey over the years have been arguably more leading edge (DNSSEC), while others are best described as quotidian (lame servers). more»

NASA Website Blocked Due to DNSSEC Error

A misconfiguration in NASA's DNSSEC implementation on its website caused Comcast's network to block users from the site last week. NASA had incorrectly signed DNSSEC in its implementation of the new security protocol that last week, causing Comcast's newly DNSSEC-enabled service to automatically block access to the site. the day part of the Web went dark in protest of controversial anti-piracy legislation, leading some users and pundits to inaccurately speculate this was Comcast's way of protesting the government-based bills. more»

DNSSEC Update from ICANN 42 in Dakar

While the global rollout of DNSSEC continues at the domain name registry level - with more than 25% of top-level domains now signed - the industry continues to focus on the problem of registrar, ISP and ultimately end-user adoption. At the ICANN meeting in Dakar in late October, engineers from some of the early-adopting registries gathered for their regular face-to-face discussion about how to break the "chicken or egg" problems of secure domain name deployment. more»

Taking the Anti-SOPA Message to the People

Six Key Issues About Operating a TLD Registry

Brand owners unfamiliar with the domain name system (DNS) are hearing that their first step in registering a top level domain (TLD) is to select a back-end TLD registry provider. The fear instilled in them is that if they don't act quickly, all available service providers will have reached their capacity. Given ICANN's tight and inflexible application submission schedule, brands don't want to be left at the starting gate. more»
