The Promise of Multi-Signer DNSSEC

DNSSEC is increasingly adopted by organizations to protect DNS data and prevent DNS attacks like DNS spoofing and DNS cache poisoning. At the same time, more DNS deployments are using proprietary DNS features like geo-routing or load balancing, which require special configuration to support using DNSSEC. When these requirements intersect with multiple DNS providers, the system breaks down. more

What's in Your DNS Query?

Privacy problems are an area of wide concern for individual users of the Internet -- but what about network operators? Geoff Huston wrote an article earlier this year concerning privacy in DNS and the various attempts to make DNS private on the part of the IETF -- the result can be summarized with this long, but entertaining, quote. more

DNS and the Internet of Things: Opportunities, Risks, and Challenges

The ICANN Security and Stability Advisory Committee (SSAC) has recently published SAC105, a report on the interplay between the DNS and the Internet of Things (IoT). Unlike typical SSAC publications, SAC105 does not provide particular recommendations to the ICANN Board, but instead is informative in nature and intends to trigger and facilitate dialogue in the broader ICANN community. more

Network Protocols and Their Use

In June, I participated in a workshop, organized by the Internet Architecture Board, on the topic of protocol design and effect, looking at the differences between initial design expectations and deployment realities. These are my impressions of the discussions that took place at this workshop. ... In this first part of my report, I'll report on the case studies of two protocol efforts and their expectations and deployment experience. more

A Report on DNS Operations, Analysis, and Research Center (DNS-OARC) 30th Meeting

DNS Operations, Analysis, and Research Center (DNS-OARC) held its 30th meeting in Bangkok on the 12th and 13th May. Here's what attracted my interest from two full days of DNS presentations and conversations, together with a summary of the other material that was presented at this workshop. Some Bad News for DANE (and DNSSEC): For many years the Domain Name X509 certification system, or WebPKI, has been the weak point of Internet security... more

Why More Registries Should Be Talking About DNS Security

I've been incredibly lucky in my time at Neustar to lead both the exceptional Registry and Security teams. While these divisions handle their own unique product and service offerings, it's clear that they have some obvious crossovers in their risks, opportunities and challenges. Having been closely involved in the strategy of both these teams, it strikes me that there is more we as Registry Operators and service providers can and should be doing to align the world of cybersecurity with that of domain names. more

Unexpected Effects of the 2018 Root Zone KSK Rollover

March 22, 2019, saw the completion of the final important step in the Key Signing Key (KSK) rollover - a process which began about a year and half ago. What may be less well known is that post rollover, and until just a couple days ago, Verisign was receiving a dramatically increasing number of root DNSKEY queries, to the tune of 75 times higher than previously observed, and accounting for ~7 percent of all transactions at the root servers we operate. more

Some Thought on the Paper: Practical Challenge-Response for DNS

Because the speed of DNS is so important to the performance of any connection on the 'net, a lot of thought goes into making DNS servers fast, including optimized software that can respond to queries in milliseconds, and connecting DNS servers to the 'net through high bandwidth links. To set the stage for massive DDoS attacks based in the DNS system, add a third point: DNS responses tend to be much larger than DNS queries. more

Say YES to DNSSEC

With the latest "DNSpionage" attack, ICANN astutely prompted domain name holders to fully deploy DNSSEC on their names. Afilias absolutely supports this and encourages the same. In this post, I remind you of why DNSSEC is important and our continued role. Afilias has a long history in the development and advocacy of DNSSEC. In 2007, we partnered with Public Interest Registry to help found dnssec-deployment.org. more

Building a Secure Global Network

Recently, the DNS has come under an extensive attack. The so-called "DNSpionage" campaigns have brought to light the myriad methods used to infiltrate networks. These attacks employed phishing, system hopping via key exfiltration, and software zero day exploits, illustrating that many secure networks may not be fully protected. more

Call for Proposals: ICANN 64 DNSSEC Workshop in Kobe, Japan (March 2019)

Will you be at the ICANN 64 meeting in March 2019 in Kobe, Japan? If so (or if you can get to Kobe), would you be interested in speaking about any work you have done (or are doing) with DNSSEC, DANE or other DNS security and privacy technologies? If you are interested, please send a brief (1-2 sentence) description of your proposed presentation before 07 February 2019. more

KSK Rollover, Elliptical Curve Vulnerabilities, Surveillance and Privacy. Are We Building Trust?

ICANN just recently performed a Root Zone DNS Security Extensions (DNSSEC) Key Signing Key (KSK) Rollover. The recent KSK Rollover that took place on the 11th October 2018. The KSK Rollover has been successful and congratulations are in order. The Root Zone DNSSEC Key Signing Key "KSK" is the top most cryptographic key in the DNSSEC hierarchy. The KSK is a cryptographic public-private key pair. more

How to Prepare for the DNSSEC Root KSK Rollover on October 11, 2018

Are you ready? Are your systems prepared so that DNS will keep functioning for your networks? One week from today, on Thursday, October 11, 2018, at 16:00 UTC ICANN will change the cryptographic key that is at the center of the DNS security system - what we call DNSSEC. The current key has been in place since July 15, 2010. This is a long-planned replacement. more

The Root KSK Rollover? What Does It Mean for Me?

In a little over two weeks, precisely in 17 days (on 11 October 2018 at 16:00 UTC), ICANN will roll the Domain Name System Security Extensions (DNSSEC) root Key Signing Key (KSK). If you are a Domain Name System (DNS) and DNSSEC expert already engaged globally on the topic, you are certainly both well aware and ready for the rollover. This article is probably not for you! If however, you are out there focused on your day to day running or managing a DNS infrastructure... more
