Minimum Disclosure: What Information Does a Name Server Need to Do Its Job?

Two principles in computer security that help bound the impact of a security compromise are the principle of least privilege and the principle of minimum disclosure or need-to-know. As described by Jerome Saltzer in a July 1974 Communications of the ACM article, Protection and the Control of Information Sharing in Multics, the principle of least privilege states, "Every program and every privileged user should operate using the least amount of privilege necessary to complete the job." more

AFRINIC Partners With ICANN on AFRICA DNS Business Exchange Programme

A series of internships have been set up to facilitate capacity building for registrars and registries in Africa to boost the African domain name business. Launched by ICANN in partnership with AFRINIC, the first phase of the DNS Business Exchange Programme involved interns selected from ICANN accredited registrars. more

Notes from NANOG 63

The following is a selected summary of the recent NANOG 63 meeting, held in early February, with some personal views and opinions thrown in! ...One view of the IETF's positioning is that as a technology standardisation venue, the immediate circle of engagement in IETF activities is the producers of equipment and applications, and the common objective is interoperability. more

The Why and How of DNS Data Analysis

A network traffic analyzer can tell you what's happening in your network, while a Domain Name System (DNS) analyzer can provide context on the "why" and "how." This was the theme of the recent Verisign Labs Distinguished Speaker Series discussion led by Paul Vixie and Robert Edmonds, titled Passive DNS Collection and Analysis -- The "dnstap" Approach. more

Over 75% of All Top-Level Domains (TLDs) Now Signed With DNSSEC

As I was entering in data for the weekly DNSSEC Deployment Maps, I was struck by the fact that we are now at the point where 617 of the 795 top-level domains (TLDs) are now signed with DNSSEC. You can see this easily at Rick Lamb's DNSSEC statistics site...Now, granted, most of that amazing growth in the chart is because all of the "new generic TLDs" (newgTLDs) are required to be signed with DNSSEC, but we are still seeing solid growth around the world. more

Where Do Old Protocols Go To Die?

In Ripley Scott's classic 1982 science fiction film Blade Runner, replicant Roy Batty (portrayed by Rutger Hauer) delivers this soliloquy... "I've...seen things you people wouldn't believe... Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those... moments... will be lost in time, like (cough) tears... in... rain. Time... to die." more

DNSSEC Adoption Part 3: A Five Day Hole in Online Security

Implementing security requires attention to detail. Integrating security services with applications where neither the security service nor the application consider their counterpart in their design sometimes make plain that a fundamental change in existing practices is needed. Existing "standard" registrar business practices require revision before the benefits of the secure infrastructure foundation DNSSEC offers can be realized. more

The Resolvers We Use

The Internet's Domain Name System is a modern day miracle. It may not represent the largest database that has ever been built, but nevertheless it's truly massive. And even if it's not the largest database that's ever been built, it's perhaps one of the more intensively used... Given the fragmentation of the IPv4 address space with the widespread use of various forms of address sharing, then it increasingly looks as if the DNS is the only remaining common glue that binds the Internet together as a single network. more

ccTLDs Might Be Property

The long-running saga of victims who are pursuing 'state sponsors of terrorism' via ICANN has taken yet another turn. Some time back the Plaintiffs in Rubin & ors -v- Islamic Republic of Iran & ors managed to obtain Writs of Attachment in the Federal court district in Washington (D.C.) courts ordering that the ccTLDs of those respective countries be seized in part-payment of the damages they are owed. ICANN, fairly predictably, became involved at this point. more

U.S. Court Overrules Attempt to Seize Iran’s, Syria’s and North Korea’s Domains

In a landmark ruling, a U.S. federal court has agreed with the Internet Corporation for Assigned Names and Numbers (ICANN) that the country code Top-Level Domains (ccTLDs) are not property subject to attachment and thus overruled an attempt to seize Iran's, Syria's and North Korea's domains as part of a lawsuit against those countries' governments. more

Summary of the Registration Operations Association Workshop

I'd like to thank the 64 people that took the time to attend and participate in the discussion, both in-person and remote. I started the workshop with an introduction to some of the technical challenges being faced by the domain registration industry. more

An Open Letter to the Prime Minister of India, from Within India, Through an Internet Blog

Hon' Prime Minister, Why would India table Proposal 98 for the work of the ITU Plenipotentiary Conference? Contribution 98 wants the ITU to develop an IP address plan; wants it to be a contiguous IP address platform so as to enable the Governments to map and locate every Internet user; suggests that the ITU may coordinate the distribution of IP addresses accordingly; instructs the ITU Secretary General to develop policies for... naming, numbering and addressing which are [already] systematic, equitable... more

DNSSEC Adoption Part 2: The Current Functionality Gap

Registrars have the opportunity to fundamentally change the landscape of the Internet's security infrastructure by working to close the DNSSEC functionality gap. Virtually everything every Internet user does on the Internet depends on the DNS. DNSSEC is not just about protecting the DNS, it is about building a secure infrastructure foundation upon which new and innovative services and applications can be built to benefit us all. Registrars are the linchpins to advancing the deployment of DNSSEC. more
