Putting Multiple Root Nameserver Issue to Rest

I am often asked what I think of multiple root nameserver systems -- sort of like the Public-Root or the Open Root Server Confederation (ORSC) pushed by others in the past years. Whenever some well meaning person asks me for multiple roots in DNS, I answer: "DNS is a distributed, coherent, autonomous, hierarchical database. It is defined to have a single root, and every one of the hundreds of millions of DNS-speaking devices worldwide has the single-root design assumptions built into it. It would theoretically be possible to design a new system that looked superficially..." more

Hypertext Mail Protocol (a.k.a. Stub Email): A Proposal

Back in the days of dial-up modems and transfer speeds measured in hundreds of bits per second, unwanted email messages were actually felt as a significant dent in our personal pocketbooks. As increases in transfer speeds outpaced increases in spam traffic, the hundreds of unwanted emails we received per week became more of a nuisance than a serious financial threat. Today sophisticated spam filters offered by all major email providers keep us from seeing hundreds of unwanted emails on a daily basis, and relatively infrequently allow unwanted messages to reach our coveted Inboxes. So, to some degree, the spam problem has been mitigated. But this "mitigation" requires multiple layers of protection and enormous amounts of continually-applied effort. more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

Europe is to the US Controlled GPS as Europe is to the US Controlled DNS Root?

An Analogy: Europe is to the US controlled GPS as Europe is to the US controlled DNS root? That's not a very good title is it? But it does express the point I want to make. This week the European Union launched the first satellite of its own global positioning system, Galileo. One has to wonder why the Europeans feel they need to do this. Isn't the GPS system run by the United States a perfectly good system? more

Should the Government Prepare a Preemptive Cyber-Attack?

The House Committee on Science recently held a hearing to "examine the extent of U.S. vulnerability to cyber attacks on critical infrastructure such as utility systems, and what the federal government and private sector are doing, and should be doing, to prevent and prepare for such attacks." Specific issues addressed at the hearing included whether: 1) the U.S. is able to detect, respond to, and recover from cyber-attacks on critical infrastructure; and 2) is there a clear line of responsibility within the federal government to deal with cybersecurity... more

We Hate Spam Except, Of Course, When It’s Inconvenient to Do So

Paul Graham is a smart guy who popularized naive Bayesian spam filtering in 2002 with A Plan for Spam and has organized a series of informal spam conferences at MIT. Earlier this month he was shocked and horrified to discover that his web site, hosted at Yahoo where he used to work, had appeared on the widely used Spamhaus blacklist... more

Security by Obscurity?

Ah yes, 'Security by obscurity': "Many people believe that 'security through obscurity' is flawed because... secrets are hard to keep." I'm glad the guys guarding the A Root Servers are up on the latest security trends. Of course, you could hide the A Root Servers at the heart of the Minotaur's maze, but they're still going to be "right over there" in cyberspace, at 198.41.0.29 more

Mozilla Implements TLD Whitelist for Firefox in Response to IDN Homographs Spoofing

Mozilla Foundation has announced changes to Firefox concerning Internationalized Domain Names (IDN) to deal with homograph spoofing attacks. According to the organization, "Mozilla Foundation products now only display IDNs in a whitelist of TLDs, which have policies stating what characters are permitted, and procedures for making sure that no homographic domains are registered to two different entities." Following is a statement explaining the current status of the Mozilla changes to Firefox regarding IDN... more

Ask Vint Cerf: The Road Ahead for Top-Level Domains

As most readers are no doubt aware, when it comes to the topic of Top-Level Domains (TLDs), Internet Corporation for Assigned Names and Numbers (ICANN) takes center stage. Vint Cerf, Google's VP and Chief Internet Evangelist, who has served as chairman of the board of ICANN since the November of 1999 has accepted CircleID's invitation to directly respond to your questions on the topic. This is your opportunity to have your Top-Level Domain related questions responded by Vint Cerf. more

The Politics of Email Authentication, 2006 Edition

A student at a well-known US university wrote me and asked whether, given the huge national interest in getting the industry to unite behind (at least) one format, did I think that the FTC should've played a stronger role in pushing the industry to adopt an authentication format? I said: Nope. Part of the reason it's taking so long to agree on a standard is that the process is infested with academic theoreticians who are more interested in arguing about hypotheticals and pushing their pet spam solutions than in doing something useful... more

The XXX Train Wreck in Vancouver

It is now clear that by sending its letter of August 12 blocking approval of the .XXX domain, the US Government has done more to undermine ICANN's status as a non-governmental, multi-stakeholder policy body than any of its Internet governance "enemies" in the ITU, China, Brazil, or Iran. And despite all the calls for a government role that would ensure "rule of law" and "accountability" of ICANN, the interventions of governments are making this aspect of Internet governance more arbitrary and less accountable. more

Google Sued for Trademark Infringement Based on Third-Level Subdomain

It's no surprise that Google has been sued again for trademark infringement, but the basis of this lawsuit is surprising. Rather than another lawsuit over the sale of trademarked keywords to deliver ads (along the lines of the GEICO, American Blinds, Rescuecom and JTH Tax cases, or the dozens of international lawsuits), this lawsuit is based on a Blogspot blog URL. Because of its comparative novelty, this lawsuit raises some complex and unsettled legal issues. more

Splitting the Root: It’s Too Late

One of the consistent chants we've always heard from ICANN is that there has to be a single DNS root, so everyone sees the same set of names on the net, a sentiment with which I agree. Unfortunately, I discovered at this week's ICANN meeting that due to ICANN's inaction, it's already too late. Among the topics that ICANN has been grinding away at is Internationalized Domain Names (IDNs) that contain characters outside the traditional English ASCII character set. more

Urban Identity by City Top-Level Domains

This document is intended to be a starting point for a discussion on upcoming city Top-Level Domain Names (city TLDs) such as .berlin, .nyc, or .london. It reflects considerations about the impact of city TLDs on the city society, the individuals in the city, the regional and global environment, and the Internet at large. more

The Problem With Wikis

Wikis have been around for a long time on the Web. It's taken a while for them to transform from geek tool to a mainstream word, but we're here now. Last week at the ICANN Meeting in Vancouver, it was fun to watch hundreds of people get introduced to Wikis and start using them, thanks to Ray King's ICANN Wiki project. In the past few days since, I've come to believe that Wikis are doomed unless they start thinking about security in a more serious way. more
