Andrew McLaughlin reporting in the White House website: "Last week marked a significant advance in the security of the Internet. After years of intensive design, testing, and implementation work, the Internet's domain name system now has a new security upgrade that allows Internet service providers and end users alike to protect against an important online vulnerability: the clandestine redirecting of online communications to unwanted destinations." more
July 15, 2010 (yesterday) marked the end of the beginning for DNSSEC, as the DNS root was cryptographically signed. For nearly two decades, security researchers, academics and Internet leaders have worked to develop and deploy Domain Name System Security Extensions (DNSSEC). DNSSEC was developed to improve the overall security of the DNS, a need which was dramatized by the discovery of the Kaminsky bug a few years ago. more
As many of you may know, today .ORG announced that all of its 8.5 million domains are now able to be fully DNSSEC signed - the largest set of domain names in the world so far that has access to this key security upgrade. .. The widespread publicity that the Kaminsky bug got around the world vindicated a decision made in several companies to invest time, effort and money into deploying DNSSEC. The community was split on the value of the DNSSEC effort -- many thought the deployment was quixotic, while a few others thought it was appropriate. more
Attendees at the public ICANN meeting in Brussels today heard from over two dozen companies that have implemented or are planning to support DNSSEC, the next-generation standard protocol for secured domain names. It is clearer than ever before that DNSSEC is becoming a reality. more
With DNSSEC for the root zone going into production in a couple of weeks, it is now possible for Top Level Domain (TLD) managers to submit their Delegation Signer (DS) information to IANA. But what does this really mean for a TLD? In this post we're going to try to sort that out. more
The global deployment of Domain Name System Security Extensions (DNSSEC) is charging ahead. With ICANN 38 Brussels just around the corner, DNSSEC deployment will inevitably be the hot topic of discussion over the next few days. Case in point, today, ICANN hosted the first production key ceremony at a secure facility in Culpepper, Va. where the first cryptographic digital key was used to secure the Internet root zone. The ceremony's goal was simple: for the global Internet community to trust that the procedures involved with DNSSEC are executed correctly and that the private key materials are stored securely. more
The barriers to DNSSEC adoption are quickly disappearing. There are nearly 20 top-level domains that have already deployed DNSSEC including generic TLDs like .org and .gov. This July, the DNS root will also be signed, and will begin validating. At this point, the decision for remaining TLDs to deploy DNSSEC is really no longer a question. more
ICANN will hold the first Root Zone DNSSEC KSK Ceremony on Wednesday 2010-06-16 in Culpeper, VA, USA. ... Attendance within the key ceremony room itself will be limited to just those with an operational requirement to execute the ceremony. However, since this event has generated significant interest, we have made additional space available in an adjacent room for observers who wish to attend the event. more
The most recent episode of The Ask Mr. DNS Podcast offers up some disturbing corroborating evidence as to the extent of DNS filtering and outright blocking occurring in China. VeriSign's Matt Larson and InfoBlox's Cricket Liu, who co-host the geeky yet engaging and extremely informative show, held a roundtable discussion including technical experts from dynamic name service providers (better known as "managed DNS" services) DynDNS, TZO, No-IP, and DotQuad, as well as Google and Comcast. more
The deployment of Domain Security Extensions (DNSSEC) has crossed another milestone this month with the publication of DURZ (deliberately unvalidatable root zone) in all DNS root servers on 5 May 2010. While this change was virtually invisible to most Internet users, this event and the remaining testing that will occur over these next two months will dictate the ultimate success of DNSSEC deployment across the Internet. more
The project to sign the DNS root zone with DNSSEC took an additional step toward completion yesterday with the last of the "root server" hosts switching to serving signed DNSSEC data. Now every DNS query to a root server can return DNSSEC-signed data, albeit the "deliberately unvalidatable" data prior to the final launch. Another key piece for a working signed root is the acceptance of trust anchors in the form of DS records from top-level domain operators. These trust anchors are used to form the chain of trust from the root zone to the TLD. more
IT security specialists have known for years that the plain DNS is not to be trusted. Any hope for improvement rests on the DNSSEC protocol deployment. In this post, I will review the current status in one critical aspect, namely the DNS root signature key management. The other two foremost are the application usage of DNSSEC protocol functionality and the operational front, or the extent of deployment in the DNS infrastructure. The operational front includes the support by the DNS root nameservers, but my focus on signature key management leaves this issue aside. more
You may have seen media reports a few weeks ago describing how servers behind the so-called Great Firewall of China were found delivering incorrect DNS information to users in the rest of the world, thereby redirecting users to edited Web pages. Reports indicate that this apparently occurred due to a caching error by a single Internet Service Provider. While the problem was fairly limited in scope, it could have entirely been prevented in a world where DNSSEC was fully deployed. more
The year 2010 is turning out to be the "year of DNSSEC" from Registry implementations, Registrar implementations, ISP support, to the Root being signed this summer. Because we are dealing with such critical infrastructure, it is important to not lose sight of careful implementations. more
Leading US ISP, Comcast, has announced today its aggressive plans to deploy DNSSEC through out its netowrk. Chris Griffiths, Manager of DNS Engineering, writes: "We plan to implement DNSSEC for the websites we manage, such as comcast.com, comcast.net and xfinity.com, by the first quarter of 2011, if not sooner. By the end of 2011, we plan to implement DNSSEC validation for all of our customers." more
