Internet Infrastructure: Stability at the Core, Innovation at the Edge (Part 2 of 5)

For nearly all communications on today's Internet, domain names play a crucial role in providing stable navigation anchors for accessing information in a predictable and safe manner, irrespective of where you're located or the type of device or network connection you're using. Over the past 15 years hundreds of millions of domain names have been added to the Internet's Domain Name System (DNS), and well over two billion (that's Billion!) new users, some ~34 percent of the global population, have become connected. more

Counter-eCrime Operations Summit (APWG) In Prague Next Week

The sixth annual Counter-eCrime Operations Summit (CeCOS VI) will engage questions of operational challenges and the development of common resources for the first responders and forensic professionals who protect consumers and enterprises from the ecrime threat every day. This year's meeting will focus on the shifting nature of cybercrime and the attendant challenges of managing that dynamic threatscape. more

An Astonishing Collaboration

Wow. It's out. It's finally, finally out... So there's a bug in DNS, the name-to-address mapping system at the core of most Internet services. DNS goes bad, every website goes bad, and every email goes...somewhere. Not where it was supposed to... I'm pretty proud of what we accomplished here. We got Windows. We got Cisco IOS. We got Nominum. We got BIND 9, and when we couldn't get BIND 8, we got Yahoo, the biggest BIND 8 deployment we knew of, to publicly commit to abandoning it entirely. It was a good day... 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

ICANN Chairman’s Durban Roundup

Respected ICANN Chairman of the Board Steve Crocker has wrapped up his organisation's 47th International Meeting, held in Durban last week, with a message to the community. This message, reproduced here in its entirety, provides both a useful and concise summary of the Durban meeting and insights into the Chairman's view of where ICANN stands at the moment, the successes it has notched up and the challenges it faces. more

DNSSEC Failure Causes Massive Website Outages on Russian Internet

A DNSSEC failure plunged hundreds of Russian-language websites into darkness on Tuesday evening, rendering .ru and .рф domains inaccessible. The outage affected users both within and outside Russia, with major platforms such as Tinkoff Bank, Avito, Wildberries, Yandex, and MTS experiencing disruptions. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 2)

This post follows an earlier post about DNS amplification attacks being observed around the world. DNS Amplification Attacks are occurring regularly and even though they aren't generating headlines targets have to deal with floods of traffic and ISP infrastructure is needlessly stressed -- load balancers fail, network links get saturated, and servers get overloaded. And far more intense attacks can be launched at any time. more

Cryptographic Tools for Non-Existence in the Domain Name System: NSEC and NSEC3

In my previous post, I described the first broad scale deployment of cryptography in the DNS, known as the Domain Name System Security Extensions (DNSSEC). I described how a name server can enable a requester to validate the correctness of a "positive" response to a query -- when a queried domain name exists -- by adding a digital signature to the DNS response returned. 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

ISOC Joins Forces with Shinkuro and Parsons to Promote Global Deployment of DNSSEC

The Internet Society today announced it has signed a Memorandum of Understanding with Shinkuro and Parsons to collaborate on multiple initiatives to promote the global deployment of Domain Name System Security Extensions (DNSSEC). more

Now Available - A Trend Chart Tracking DNSSEC Validation Globally

How can we track the amount of DNSSEC validation happening globally? Is there a way we can see the trend over time to (we hope!) see validation rise? At the recent excellent DNSSEC Workshop at ICANN 50 in London Geoff Huston let me know that his APNIC Labs team has now created this exact type of trend chart. 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

Ongoing Community Work to Mitigate Domain Name System Security Threats

For over a decade, the Internet Corporation for Assigned Names and Numbers (ICANN) and its multi-stakeholder community have engaged in an extended dialogue on the topic of DNS abuse, and the need to define, measure and mitigate DNS-related security threats. With increasing global reliance on the internet and DNS for communication, connectivity and commerce, the members of this community have important parts to play in identifying, reporting and mitigating illegal or harmful behavior, within their respective roles and capabilities. more

DNS… Wait a SEC

Complete DNSSEC implementation requires that domains are authenticated at the root by the Registry, and that DNS zones and records are authenticated as well. Now before I go any further, let me begin by stating that I fully support the development and deployment of DNSSEC and that the vulnerabilities presented by Cache Poisoning are very real, especially for those websites collecting login credentials or other types of sensitive information. more

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
