DNSSEC Root Signature, Almost There!

IT security specialists have known for years that the plain DNS is not to be trusted. Any hope for improvement rests on the DNSSEC protocol deployment. In this post, I will review the current status in one critical aspect, namely the DNS root signature key management. The other two foremost are the application usage of DNSSEC protocol functionality and the operational front, or the extent of deployment in the DNS infrastructure. The operational front includes the support by the DNS root nameservers, but my focus on signature key management leaves this issue aside. more

DNS Attack Takes Down Internet in Five Northern and Coastal Provinces of China

According to Shanghai Daily, there has been an "organized Internet attack on Tuesday night which caused serious congestion in several provinces [in China] and left millions of users unable to gain access to the Internet." This is the first time the regulator has published news about an investigation into an online attack in China within 24 hours, says Shanghai Daily. ..."It was an attack on DNS (Domain Name System) and the carriers and related firms should do more back-up to avoid similar incidents," the ministry said in a statement. more

Why Most People Haven’t Heard of the DNS Root Server System

At the ICANN 81 meeting in Istanbul on 10 November 2024, I gave a presentation about the DNS Root Server System, in an effort to increase understanding of the Root Server System (RSS) and Root Server Operators (RSOs). The talk was intended for the members of the ICANN Governmental Advisory Committee (GAC), but much of this explanation may be of interest to general audiences. more

An Investigation Shows How Bomb Threat Scammers Hijacked Thousands of Big-Name Domains

Ars Technica's Dan Goodin reports that an "investigation shows the spam run worked by abusing a weakness at GoDaddy that allowed the scammers to hijack at least 78 domains belonging to Expedia, Mozilla, Yelp, and other legitimate people or organizations." more

One Big Cheer for ICANN - But Still a Way’s from Our “Gooool”

As we approach the World Cup in South Africa this June it's heartening to see the amount of attention being paid to the continent. As with ICANN's recent Nairobi meeting, the eyes of the world are focusing on Africa in a new way -- as a sophisticated marketplace, and as a destination for investment, technology, and yes, sports... Still, as we prepare for the Cup and as we celebrate ICANN's recent approval of more Internationalized Domain Names (IDNs), our job as an Internet community remains unfinished. Too many scripts and thus too many key voices remain "off the pitch". more

Fairness & Due Process Require Changes to ICANN’s “Updated Supplementary Procedures” to the IRP

The Updated Supplementary Procedures for Independent Review Process ("IRP Supplementary Procedures") are now up for review and Public Comment. Frankly, there is a lot of work to be done. If you have ever been in a String Objection, Community Objection, or negotiated a Consensus Policy, your rights are being limited by the current way the IRP Supplementary Procedures proposal is structured. With timely edits, we can ensure that all directly-impacted and materially-affected parties have actual notice of the IRP proceeding... more

The Netizen’s Guide to Reboot the Root (Part I)

In the world of ICANN and Internet policy, complexity is manufactured to create an illusion that issues are impenetrably technical such that normal and everyday principles can't apply. This causes a pervasive and entrenched phenomenon of eyes that glaze over at the mere mention of the word "ICANN" -- including those of government regulators and other officials that might otherwise take more of an active interest. more

DNS Server Hijacking Results in Funds Being Stolen from Popular Crypto Website, MyEtherWallet

Close to 1300 IP addresses were hijacked this morning resulting in Amazon losing control of a number of its highly used cloud services. 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

A Great Collaborative Effort: Increasing the Strength of the Zone Signing Key for the Root Zone

A few weeks ago, on Oct. 1, 2016, Verisign successfully doubled the size of the cryptographic key that generates DNSSEC signatures for the internet's root zone. With this change, root zone DNS responses can be fully validated using 2048-bit RSA keys. This project involved work by numerous people within Verisign, as well as collaborations with ICANN, Internet Assigned Numbers Authority (IANA) and National Telecommunications and Information Administration (NTIA). more

A Closer Look at the AIP Internet Draft Proposal

Just in time for ICANN's 44th meeting next week, a new Internet Draft has turned up, purporting to fix the centralization of the DNS. The draft has received some attention, including an article in PC World. It isn't entirely clear what the real purpose of the draft is, but it is hard to credit the notion that it is solving any technical problem. Without examining the reasons why the draft exists, I want to debunk a claim in it. more

The Introduction of New Domain Name Services: “Due Process” and Innovation

For those interested in encouraging innovation in the domain name space -- which presumably includes the ICANN community currently convening in Dakar -- the recent episode in which VeriSign proposed, and then quickly withdrew, a bundle of new services (the VeriSign anti-abuse domain use policy) raises important issues that will be revisited as new gTLDs are introduced. Some of those issues are referenced in a recent blog post by Milton Mueller, but his emphasis on "due process" suggests a regulatory framework that is not friendly to innovation. more

Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 1: Understanding the Risks

Ah, BYOD. How I love thee. BYOD, or "Bring Your Own Device", gives me choices. I can use a device at work I actually like and am most effective with. (How did I ever get by without my iPad?) But BYOD comes with challenges. Personal devices can be infected with malware. Once they're connected to an enterprise's network, they can be controlled by a bot master to hijack enterprise resources and wreak havoc as part of a botnet. more

The Future of Internet Governance? Comments on IGF 2018 Speech by French President Emmanuel Macron

Macron has declared the Internet to be under threat. Without stepping back to question and explore the underlying causes of those threats, he uses them as a justification to propose a different approach to, albeit limited, current Internet Governance processes. Here we explore his proposals and some of the issues they generate. He acknowledges that Civil Society and the private sector have been core drivers in the creation of the Internet. He argues that its benefits and existence are endangered by predatory practices. more

US House Committee Announces Oversight Hearing on DNS and Search Engine Blocking

House Committee on Oversight and Government Reform Chairman Darrell Issa today announced that the Full Committee will hold a hearing on January 18 to examine the potential impact of Domain Name Service (DNS) and search engine blocking on security, jobs and the Internet community. The Committee will hear testimony from cybersecurity experts and others from the technology community. more
