DNS Security


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

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

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

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

DNS Security / Most Commented

DNSSEC Adds Value?

The recent news that .uk, .arpa and .org may sign their zones sometime this year is indeed good news. Each domain is highly significant... As the DNSSEC registry infrastructure moves inexorably forward -- primarily driven by top level pressure and considerations of National Interest -- it now behoves us to clearly articulate the benefits of DNSSEC to domain owners and registrars. In particular I want to focus on the vast majority of us to whom cold, hard cash is important and parting with it requires as a minimum tangible benefits or, in extreme cases, surgical intervention. more»

Developing Internet Standards: How Can the Engineering Community and the Users Meet?

There is currently a discussion going on between Milton Mueller and Patrik Fältström over the deployment of DNSSEC on the root servers. I think the discussion exemplifies the difficult relation between those who develop standards and those who use them. On the one hand, Milton points out that the way the signing of the root zone will be done will have a great influence on the subjective trust people and nation states will have towards the system. On the other hand, Patrik states that "DNSSEC is just digital signatures on records in this database". Both are right, of course, but they do not speak the same language... more»

Social Networking and Web 2.0 Creating DNS Performance Issues for Carriers

A revolution is taking place on the Internet, with new sites redefining how we interact online. The next-generation Internet is emerging in collaborative and interactive applications and sites with rich, varied media (images, video, music). As with many revolutions, this one is driven by the younger generation, which is adopting social networking sites like MySpace and video sharing sites like Google's YouTube. But the general shift is not restricted to the young, as more mature consumers and businesses alike are exploring the possibilities of collaborative, media-rich applications. This major shift in Internet applications has its unintended victims. One of them turns out to be the Domain Name System (DNS). more»

Breaking the Internet HOWTO: The Unintended Consequences of Governmental Actions

"Breaking the Internet" is really hard to do. The network of networks is decentralized, resilient and has no Single Point Of Failure. That was the paradigm of the first few decades of Internet history, and most people involved in Internet Governance still carry that model around in their heads. Unfortunately, that is changing and changing rapidly due to misguided government intervention. more»

DNSSEC Deployment Reaching Critical Mass

Less than nine months after the DNS root was signed, the rollout of DNSSEC across the Internet's top-level domains is approaching the tipping point. Thanks to the combined efforts of registries around the world, the new security protocol will soon be available to the majority of domain name registrants in almost a quarter of all TLDs. more»

DNS Clients Do Request DNSSEC Today

After the DNS root zone was finally signed and a number of Top-Level Domains (TLDs) began signing their zones, we were curious to see how many clients actually request DNSSEC information. We looked at the RIPE NCC server that provides secondary service to several country code top-level domains (ccTLDs). more»

Another Attack, Another Reason for the Urgency of DNSSEC Adoption

News broke this week about an attack in Puerto Rico that caused the local websites of Google, Microsoft, Yahoo, Coca-Cola, PayPal, Nike, Dell and Nokia to be redirected for a few hours to a phony website. The website was all black except for a taunting message from the computer hacker responsible for the attack... more»

And the Wait Continues for .Corp, .Home and .Mail Applicants

On 6 March 2017, ICANN's GDD finally responded to an applicant letter written on 14 August 2016 to the ICANN Board. This was not a response from the ICANN Board to the letter from 2016 but a response from ICANN staff. The content of this letter can best be described as a Null Response. It reminded the applicants that the Board had put the names on hold and was still thinking about what to do. more»

Wow! BIND9 9.10 Is out, and What a List of Features!

Today the e-mail faerie brought news of the release of BIND9 9.10.0 which can be downloaded from here. BIND9 is the most popular name server on the Internet and has been ever since taking that title away from BIND8 which had a few years earlier taken it from BIND4. I used to work on BIND, and I founded ISC, the home of BIND, and even though I left ISC in July 2013 to launch a commercial security startup company, I remain a fan of both ISC and BIND. more»

OpenDNS Adopts Proposed DNS Security Solution: DNSCurve

For more than 15 years, the IETF has been working on DNSSEC, a set of extensions to apply digital signatures to DNS. Millions of dollars in government grants and several reboots from scratch later, DNSSEC is just starting to see real world testing. And that testing is minimal -- only about 400 of the more than 85,000,000 .com domains support DNSSEC, fewer than 20% of US government agencies met their mandated December 31, 2009 deadline for DNSSEC deployment, and only two of the thirteen root zone name servers is testing with even dummy DNSSEC data. more»

Internationalizing the Internet

One topic does not appear to have a compellingly obvious localization solution in the multi-lingual world, and that is the Domain Name System (DNS). The subtle difference here is that the DNS is the glue that binds all users' language symbols together, and performing localized adaptations to suit local language use needs is not enough. What we need is a means to allow all of these language symbols to be used within the same system, or "internationalization". more»

Secure Unowned Hierarchical Anycast Root Name Service - And an Apologia

In Internet Draft draft-lee-dnsop-scalingroot-00.txt, I described with my coauthors a method of distributing the task of providing DNS Root Name Service both globally and universally. In this article I will explain the sense of the proposal in a voice meant to be understood by a policy-making audience who may in many cases be less technically adept than the IETF DNSOP Working Group for whom the scalingroot-00 draft was crafted. I will also apologize for a controversial observation concerning the addition of new root name servers... more»

Garth Bruen Discussing Whois, DNSSEC and Domain Security

NameSmash has interviewed Garth Bruen, Internet security expert and creator of Knujon, on some key issues under discussion during the recent ICANN meetings in San Francisco. Topics include Whois, DNS Security Extensions (DNSSEC) and generic Top-Level Domains (gTLDs) -- issues of critical importance particularly with ICANN's expected roll-out of thousands of new gTLDs in the coming years. more»

Moving DNSSEC Forward: Help for Registries, Registrars, ISPs/Hosting, Enterprises, and Name Owners

DNSSEC adoption has been slow, but is now picking up speed, thanks to organizations leading the way. ... While some registries have already signed, some have announced plans to sign and others are still trying to figure out their plan. Either way, DNSSEC is here. How can we make DNSSEC adoption quicker and easier not only for the registry but for individual name owners? more»

VeriSign Leaves the Security Certificate Business

Earlier this week in a press release, VeriSign said that they are selling their SSL certificate business to Symantec. VeriSign is the dominant player in this market, having absorbed competitor Thawte in 1999, and Geotrust in 2006. Three years ago, when VeriSign decided to divest its non-core businesses, they kept the certificate business. So what's changed? more»
