DNSSEC

Noteworthy

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

 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.

DNSSEC / Most Commented

An Authenticated Internet

Discussions around DNSSEC are so often focused on the root, the attacks, what DNSSEC does and doesn't do and so on -- and these are all valid and important points. But there is far less attention focused on the opportunities that will surface from an authenticated internet. ...DNSSEC is becoming more of a reality now -- rather than a technical discussion which has been stuck in the mud for 15 years. We can now begin to think about new opportunities to build from a secure DNS, opportunities that build on the certainty that you have arrived at the correct website. Today, you can't be sure. more»

Technical Comments on Mandated DNS Filtering Requirements of H. R. 3261 ("SOPA")

About two months ago, I got together with some fellow DNS engineers and sent a letter to the U. S. Senate explaining once again why the mandated DNS filtering requirements of S. 968 ("PIPA") were technically unworkable. This letter was an updated reminder of the issues we had previously covered... In the time since then, the U. S. House of Representatives has issued their companion bill, H. R. 3261 ("SOPA") and all indications are that they will begin "markup" on this bill some time next week. more»

The Problem With HTTPS SSL Runs Deeper Than MD5

The recent research highlighting the alarming practice of Secure Socket Layer (SSL) Certificate Authority (CA) vendors using the MD5 hashing algorithm (which was known to be broken since 2005) has shown a major crack in the foundation of the Web. While the latest research has shown that fake SSL certificates with MD5 hashes can be forged to perfection when the CA (such as VeriSign's RapidSSL) uses predictable certificate fields, the bigger problem is that the web has fundamentally botched secure authentication. more»

Why Not an Interim Step Until DNSSEC is Ready?

I'm interested in CircleID community's take on NeuStar's recent announcement of Cache Defender. While only effective for domains the company is authoritative for, that does cover a large number of big Internet brands and financial institutions. Why wouldn't an ISP deploy this now, while waiting for all the myriad issues involved in DNSSEC to be resolved? more»

DNSSEC: Once More, With Feeling!

After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. more»

About Those Root Servers

There is an interesting note on the ITU Strategy and Policy Unit Newslog about Root Servers, Anycast, DNSSEC, WGIG and WSIS about a presentation to ICANN's GAC. (The GAC website appears to be offline or inaccessible today.) The interesting sentence is this: Lack of formal relationship with root server operators is a public policy issue relevant to Internet governance. It is stated that this is "wrong" and "not a way to solve the issues about who edits the [root] zone file." Let's look at that lack of a formal relationship... more»

First gTLD Signed: Dot Gov

Today is a historic day as the first generic Top-Level Domain (gTLD) has been signed. Only a few other top level domains, all of which are country code Top-Level Domains (ccTLDs), have been signed to date. This step is part of the first phase of adoption. Authoritative DNS servers need to sign and publish their zones. The second part is for the resolvers on the Internet to validate the keys. Both systems working together will provide security in the DNS. more»

DNSSEC is But One Link in the Security Chain

As the implementation of DNSSEC continues to gather momentum and with a number of ccTLDs, and the '.org' gTLD having deployed it into their production systems, I think it is worth pausing to take a look at the entire DNSSEC situation. Whilst it is absolutely clear that DNSSEC is a significant step forward in terms of securing the DNS, it is but one link in the security chain and is therefore not, in itself, a comprehensive solution to fully securing the DNS system. more»

DNSSEC Happy Talk Enters a New Era

So we finally have a signed root zone. Now when is someone going to answer the question I first asked over five years ago and have still not had an answer to: How do the domain name owner's keys get into the TLD? Before we have a system people can use there have to be technical standards, validation criteria and a business model. Where are they? more»

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»
