DNS Security

The Uncertainty of Measuring the DNS

The period around the end of the nineteenth century and the start of the twentieth century saw a number of phenomenal advances in the physical sciences. There was J.J. Thompson's discovery of the electron in 1897, Max Planck's quantum hypothesis in 1900, Einstein's ground-breaking papers on Brownian motion, the photoelectric effect and special relativity in 1905, and Ernest Rutherford's study of the nucleus published in 1911 to mention but a few of the fundamental discoveries of the time. more

Building a New Era of Trust on the Internet

Since Tim Berners-Lee first introduced us to the world wide web, we have seen several major phases of its growth. From the early years -- where researchers and open Internet pioneers led the way; to the dot-com boom; to the era of social media domination; the web has come a long way. While the pandemic circling the globe has undermined many critical systems and institutions of our society, I believe it also has the potential to strengthen is the resolve of the Internet community... more

Doing Our Part for a Safer, Stronger DNS

Public Interest Registry is the industry leader of DNS Anti-Abuse efforts on the Internet. Since our inception, we have worked to empower people and organizations that use the Internet to make the world a better place. Whether a .ORG is the foundation of an individual voice, a global non-profit, or any organization that is part of the mission-driven .ORG community, we are proud to have earned the trust of so many dedicated users. more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

The Real Deployment Issue

When I see glib talk about the inevitable transition to IPv6 or DNSSEC, I have to wonder what industry people think they are working in. Let me give an example that has nothing to do with networking: storage capacity. Now if there is one constant that everyone in the computing industry can agree on it is that they expect storage media capacity to increase. more

Next Steps in Preparing for Post-Quantum DNSSEC

In 2021, we discussed a potential future shift from established public-key algorithms to so-called "post-quantum" algorithms, which may help protect sensitive information after the advent of quantum computers. We also shared some of our initial research on how to apply these algorithms to the Domain Name System Security Extensions, or DNSSEC. In the time since that blog post, we've continued to explore ways to address the potential operational impact of post-quantum algorithms on DNSSEC, while also closely tracking industry research and advances in this area. more

3 Reasons It’s Crucial to Review Your Domain Lock Portfolio Now

Just as we started the new year, the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency's (CISA) issued an alert. On January 6, 2020 , they warned of domain name system (DNS) hijacking and other cyber threats that may be used by nation-state threat actors to disrupt business activity and take control of vital internet assets. A familiar refrain heard in 2019 now repeating in 2020. more

DNSSEC - Let’s Stay the Course!

I don't know about you, but I'm starting to think that DNSSEC being so hot these days is a mixed blessing. Yes, it's wonderful that after so many years there is finally broad consensus for making DNSSEC happen. But being so prominent also means the protocol is taking shots from those who don't want to make the necessary software, hardware and operational modifications needed. And DNSSEC has taken some shots from those who just want to be contrarian. more

(DNS) Security Protocols Do What They Say on the Tin

DNS-over-TLS has recently become a welcome addition to the range of security protocols supported by DNS. It joins TSIG, SIG(0) and DNSSEC to add privacy, and, in the absence of validating stub resolvers, necessary data integrity on the link between a full-service resolver and the users' stub resolver. (The authenticated source feature of TLS may also offer some additional benefits for those of a nervous disposition.) Good stuff. What is not good stuff is... 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

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

DNSSEC Signed ROOT by 1 July 2010

Mehmet Akcin writes: As announced today as part of RIPE meeting in Lisbon, Portugal by Joe Abley, DNS Group Director at ICANN, and Matt Larson, Vice President of DNS Research at VeriSign, in their presentation (Page 25), DNSSEC for the root zone is proposed to be fully deployed by July 1, 2010. The Draft Timeline suggests Root zone being signed by December 1, 2009 while initially staying internal to ICANN and VeriSign. The incremental roll out of the signed root would then take place from January until July 2010. more

Dear U.S.A. – Observations on the Cyber Solarium Commission Report

I am writing to you as someone who is not your citizen, (although I had the fortune to wed the most beautiful of your daughters), to share my thoughts about the recent US Government Cyber Solarium Commission report. U.S.A. We owe you one! Without you and your citizens there would be no free Internet as we know it. Thank You! Your constitution is our inspiration. We, the global digital citizenship want to be "the people", in order to "secure the Blessings of Liberty to ourselves and our Posterity..." more

Five Security Blind Spots from Prolonged Implementation of a Business Continuity Plan Amid COVID-19

The novel coronavirus outbreak (COVID-19) has prompted many organizations in Mainland China and Hong Kong to execute their business continuity plan (BCP). During the last epidemic in 2003, the SARS outbreak lasted for nine months – and with an infection rate that is increasing rapidly, this new coronavirus has the potential to cause prolonged periods of commercial disruption, and heavy reliance on BCPs. more

CAICT Holds ICANN 59 China Internet Community Readout Session

In afternoon of 14th July, the China Academy of Information and Communication Technology (CAICT) and ICANN Beijing Engagement Center jointly held the ICANN 59 China Internet Community Readout Session. Mr. Zhang Ya, Deputy Director of Information and Communication Authority under the Ministry of Industry and Information Technology (MIIT), made his presence and gave opening remarks on the meeting. Over 40 representatives from the Cyberspace Administration, the Ministry of Foreign Affairs, domain name registries and registrars, industrial organizations, institutes and universities participated in the seminar. more
