Increasing the Strength of the Zone Signing Key for the Root Zone

One of the most interesting and important changes to the internet's domain name system (DNS) has been the introduction of the DNS Security Extensions (DNSSEC). These protocol extensions are designed to provide origin authentication for DNS data. In other words, when DNS data is digitally signed using DNSSEC, authenticity can be validated and any modifications detected. more»

Call for Participation - DNSSEC Workshop at ICANN 56 in Helsinki, Finland on 27 June 2016

Do you have an idea for an innovative use of DNSSEC or DANE? Have you recently deployed DNSSEC or DANE and have some "lessons learned" that you could share? Did you develop a new tool or service that works with DNSSEC? Have you enabled DNSSEC by default in your products? (And why or why not?) Do you have ideas about how to accelerate usage of new encryption algorithms in DNSSEC? more»

DNS and Stolen Credit Card Numbers

FireEye announced a new piece of malware yesterday named MULTIGRAIN. This nasty piece of code steals data from Point of Sale (PoS) and transmits the stolen credit card numbers by embedding them into recursive DNS queries. While this was definitely a great catch by the FireEye team, the thing that bothers me here is how DNS is being used in these supposedly restrictive environments. more»

My Top Takeaways from DNS-OARC 24

The 24th DNS-OARC meeting was held last week in Buenos Aires -- a two-day DNS workshop with amazingly good, consistent content. The programme committee are to be congratulated on maintaining a high quality of presentations. Here are my picks of the workshop. They fall into three groups, covering themes I found interesting... These presentations related to the ongoing problem of DNS as a source of reflection attacks, or a victim of attempted DDoS... more»

Let Me Make Yeti-DNS Perfectly Clear

The following rather alarming text caught my eye today... Had the text appeared under a less august letterhead, or signed by less qualified authors, there would be no cause for alarm. However, the letterhead was World Economic Forum and the authors were William J. Drake, Vinton G. Cerf, and Wolfgang Kleinw├Ąchter. As one of three coordinators for the Yeti-DNS project, this feels a bit like I'm in big trouble now. So, let's discuss the matter. more»

The Path Toward Increasing the Security of DNSSEC with Elliptic Curve Cryptography

How do we make DNSSEC even more secure through the use of elliptic curve cryptography? What are the advantages of algorithms based on elliptic curves? And what steps need to happen to make this a reality? What challenges lie in the way? Over the past few months we've been discussing these questions within the community of people implementing DNSSEC, with an aim of increasing both the security and performance of DNSSEC. more»

DNSSEC Workshop Streaming Live from ICANN 55 in Marrakech on Wednesday, March 9, 2016

What is the current state of DNSSEC deployment around the world and also in Africa? How can you deploy DNSSEC at a massive scale? What is the state of using elliptic curve crypto algorithms in DNSSEC? What more can be done to accelerate DNSSEC deployment? Discussion of all those questions and much more can be found in the DNSSEC Workshop streaming live out of the ICANN 55 meeting in Marrakech, Morocco, on Wednesday, March 9, from 9:00 to 15:15 WET. more»

The CCT Review Needs You!

Come join the discussion on Wednesday 17:15 UTC. Quis custodiet ipsos custodes? As ICANN approaches its 18th birthday, it marks its ascension to adulthood and independence with a new framework of accountability. As we attempt to modernize and empower the organization with oversight of the DNS, the question of "who watches the watchmen?" is on the tip of everyone's tongue. more»

Blocking and Filtering in Collaborative Security Context - A Reflection on RFC 7754

The other day, I planned to take my 15-year-old son to the movie theatre to see "Hateful Eight" in 70mm film format. The theatre would not allow him in. Under article 240a of the Dutch penal code, it is a felony to show a movie to a minor when that movie is rated 16 or above. Even though I think I am responsible for what my son gets to see, I understand that the rating agency put a 16-year stamp on this politically-incorrect-gun-slinging-gore-and-curse-intense-comedy feature. more»

ICANN 55 Next Week In Marrakech - What to Expect

As you may know, ICANN holds three public meetings every year. The most recent one, ICANN 54, was held in Dublin... So the next ICANN meeting is being held in Marrakech, Morocco starting Saturday, March 5th through March the 10th. Up until now all three meetings were the same length and had the same basic structure. However, from this year onwards, that'll change. How that will play out in reality, however, is anyone's best guess. more»
