Proposal for Signing the DNSSEC Root

The U.S. National Telecommunications and Information Administration (NTIA) is soliciting comments on signing the DNSSEC root. Ignore the caption on the page: this is not about DNSSEC deployment, which is already happening just fine. It's about who gets to sign the root zone. more

Preventing DNS Strain When You Deploy DNSSEC

The barriers to DNSSEC adoption are quickly disappearing. There are nearly 20 top-level domains that have already deployed DNSSEC including generic TLDs like .org and .gov. This July, the DNS root will also be signed, and will begin validating. At this point, the decision for remaining TLDs to deploy DNSSEC is really no longer a question. more

A Look at the Current State of DNSSEC in the Wild

The DNS system is, unfortunately, rife with holes like Swiss Cheese; man-in-the-middle attacks can easily negate the operation of TLS and website security. To resolve these problems, the IETF and the DNS community standardized a set of cryptographic extensions to cryptographically sign all DNS records... Now that these standards are in place, how heavily is DNSSEC being used in the wild? How much safer are we from man-in-the-middle attacks against TLS and other transport encryption mechanisms? more

Why DNS Is Broken, Part 2: DoS Target

Before we get into what DNSSEC is and the benefits of it, let's talk about some of the other potential pitfalls of DNS. One of the most significant issues we have to deal with are denial-of-service (DoS) attacks. While DoS attacks are not specific to DNS we have seen DNS be a frequent target of these attacks. 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

Join Live On Sunday - 2nd Registration Operations Workshop (ROW) In Dallas

This Sunday, March 22, 2015, the second Registration Operations Workshop (ROW) will be taking place at the Fairmont Dallas hotel from 12:30 -- 4:30 pm CDT. Discussion will include extensions to EPP, new encryption initiatives and also suggestions for ways to further automate DNS interactions between registries, registrars and DNS operators, including a need to do this for DNSSEC. more

An Overview of the 27th DNS Operations, Analysis, and Research Center Meetings

The DNS Operations, Analysis, and Research Center (DNS-OARC) meetings are an instance of a meeting that concentrates on the single topic of the DNS, and in this case, it delves as deep as anyone is prepared to go! It's two days where too much DNS is barely enough! The hot topic of the meeting was the news that the proposed roll of the Key-Signing-Key of the root zone of the DNS, originally scheduled for October 11, was to be postponed. more

Notes from the DNS Privacy Workshop at NDSS 2021

For many years the consuming topic in DNS circles was that of the names themselves. If you wind the clock back twenty years or so, you will find much discussion about the nature of the Internet's namespace. Why were there both generic top-level labels and two-letter country codes? If we were going to persist with these extra-territorial generic country codes in the namespace, then how many should there be? Who could or should manage them? And so on. 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

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

DNS Survey Results Pandora’s Box of Both Frightening and Hopeful Results, Says Cricket Liu

The fifth-annual survey of domain name servers (DNS) on the public Internet -- called a "Pandora's box of both frightening and hopeful results" -- was released today by The Measurement Factory in partnership with Infoblox. more

Thinking Ahead on Privacy in the Domain Name System

Earlier this year, I wrote about a recent enhancement to privacy in the Domain Name System (DNS) called qname-minimization. Following the principle of minimum disclosure, this enhancement reduces the information content of a DNS query to the minimum necessary to get either an authoritative response from a name server, or a referral to another name server. more

DNSSEC Deployed for .COM, Internet’s Largest Top-Level Domain

DNS Security Extensions (DNSSEC) has been deployed for .COM, Internet's largest domain extension with more than 90 million registrations. The announced was made today by VeriSign, the registry operator for .COM. more

ICANN 46 Starts This Week In Beijing - Remote Participation Is Possible

The 46th meeting of the Internet Corporation for Assigned Names and Numbers (ICANN) takes place this week in Beijing, China, and will bring together leaders from all over the world to discuss and debate a wide range of issues related to domain names and the surrounding industry. One can expect that the new gTLDs, a topic frequently discussed here on CircleID, will naturally consume a great amount of the discussion at ICANN 46. more

IS3C Report: Socio-Political and Technical Impacts of Post Quantum Cryptography Policies

At the 20th Internet Governance Forum in Lillestrøm, Norway, the UN Internet Governance Forum's dynamic coalition Internet Standards, Security and Safety (IS3C) released its new report on post-quantum policies. This report presents the findings of a collaborative study undertaken by IS3C and the French domain name registry Afnic and examines the critical need for Post-Quantum Cryptography (PQC) to achieve greater security in the ever-expanding global IoT landscape. more
