On November 4, 2003, VeriSign announced a new "trust enhancing" seal which they built using Macromedia's Flash technology...While there are problems inherent to VeriSign's approach that call into question their understanding of "The Value of Trust," there are ways they could have made this particular implementation less trivially spoofable. The flaws I demonstrate on this page are flaws in the concept and the execution rather than anything inherently flawed in Flash. Overall this kind of graphical "trustmark" is extremely easy to forge just by recreating the artwork. But in this case, you don't even have to do that. The seal can still be called directly off the VeriSign servers, yet it is easily modified, without recreating artwork, and without doing anything untoward with VeriSign's servers! more
After attending the afternoon ICANN Security & Stability Committee meeting, I realized that the issues involved fall into several related but independent dimensions. Shy person that I am *Cough*, I have opinions in all, but I think it's worthwhile simply to be able to explain the Big Picture to media and other folks that aren't immersed in our field. In these notes, I'm trying to maintain neutrality about the issues. I do have strong opinions about most, but I'll post those separately, often dealing with one issue at a time. more
A few days ago, Eric Goldman wrote an interesting thinkpiece in CircleID regarding users' feeling about privacy. He seems to conclude that the existent regulations and policies on the matter are unnecessary, since Privacy doesn't "really" matters to the consumer. Eric based his argumentation on a number of surveys, stating that, even when the user expresses concerns about their privacy, on line behavior shows a different reality. We don't want to discuss here the soundness of surveys as a reliable source of information, but the author could be assuming too much in his analysis. more
A harmful, highly unilateral and capricious action. Tons of software out there depended on the ability to tell the difference between a domain name which exists and does not. They use that to give a meaningful, locally defined error to the user, or to identify if an E-mail address will work or not before sending the mail. Many used it as a way to tag spam (which came from domains that did not exist). It is the local software that best knows how to deal with the error. more
This is a special two-part series article providing a distinct and critical perspective on Internet Protocol Version 6 (IPv6) and the underlying realities of its deployment. The first part gives a closer look at how IPv6 came about. This part exposes the myths.
Good as all this is, these attributes alone have not been enough so far to propel IPv6 into broad-scale deployment, and consequently there has been considerable enthusiasm to discover additional reasons to deploy IPv6. Unfortunately, most of these reasons fall into the category of myth, and in looking at IPv6 it is probably a good idea, as well as fair sport, to expose some of these myths as well. more

In January 1983, the Advanced Research Projects Agency Network (ARPANET) experienced a "flag day," and the Network Control Protocol, NCP, was turned off, and TCP/IP was turned on. Although there are, no doubt, some who would like to see a similar flag day where the world turns off its use of IPv4 and switches over to IPv6, such a scenario is a wild-eyed fantasy. Obviously, the Internet is now way too big for coordinated flag days. The transition of IPv6 into a mainstream deployed technology for the global Internet will take some years, and for many there is still a lingering doubt that it will happen at all. more
The IPv6 Forum, the North American IPv6 Task Force, and Charmed Technology, Inc. today announced that the U.S. IPv6 Summit 2003 will be held December 8 - 11, 2003 in Arlington, VA, at the Doubletree Crystal City. The U.S. IPv6 Summit 2003 will focus on deployment, technical depth of key IPv6 features, and applications or services of Internet Protocol version 6 (IPv6). more
I was a witness at the two prior hearing, one in 2001 and another in 2002 - it's quite an experience.
My submission to this year's hearing is online at http://www.cavebear.com/rw/senate-july-31-2003.htm
What's going to be said by the witnesses? I don't know. But I have some guesses... more
Later today, Senator Conrad Burns, who chairs the U.S. Senate subcommittee responsible for supervising ICANN, will be holding a hearing on a number of issues.
At the beginning of the year, a press release called "Burns Unveils NexGenTen Agenda For Communications Reform and Security in the 21st Century", had reported:
"U.S. Sen. Conrad Burns (R-Mont.) announced his top priorities for his chairmanship of the Senate Communications Subcommittee during the 108th legislative session. The ten items, called the Burns NexGenTen Tech Agenda, aim to strengthen security and usher reform for 21st Century Communication... more
IPv6 advocacy has been tainted by FUD and half-truth. CommsWorld recently interviewed Juniper's Jeff Doyle, who is a strong supporter of IPv6 -- but who also has little patience for IPv6 mythology. Forget security, half-true address crises and QoS: the best reason for the world to run with IPv6 is what's driven the Internet all along -- innovation. more
Please pardon me if I start this story by telling about an incident that happened to me at the Madrid airport while flying to the ICANN meetings in Rio.
It was about midnight when, after flying in from Turin, my hometown, I had to go through the passport control to reach my gate for the flight to Rio. The war between the US/UK and Iraq had started two days before, and even if the Spanish government was among its supporters, security checks were apparently proceeding as usual. Passport controls inside the EU for EU citizens usually take a few seconds, and the line ahead of me was proceeding quickly. more
Brownian motion is the ceaseless random movement of particles suspended in a warm fluid. The particles move because they are buffeted by random collisions with molecules and atoms speeding this way and that under the impetus of heat. The greater the heat, the greater the motion. But no matter how much motion and how much heat, Brownian motion brings no progress.
Today I learned from Bret Fausett's ICANN Blog that ICANN has just published its Sixth Status Report Under ICANN/US Government Memorandum of Understanding, dated March 31, 2003. This report is subtitled "Report by ICANN to United States Department of Commerce Re: Progress Toward Objectives of Memorandum of Understanding" (emphasis added.) more
John Banks is a loan officer in New York. John's supervisor recently warned John about the potential number of bad loans he may be carrying as part of his portfolio. To dump some of the bad loans he might be carrying, John came up with a scheme. He pointed his web browser to www.whois.org and entered terms denoting disease or poor health such as 'cancer' and 'illness'. This query on the Internet's WHOIS database reported results of names and addresses of domain name owners who had developed websites devoted to providing information on certain serious illnesses. John compared these names and addresses with those in his portfolio of loans. For the matches, he canceled the loans and required immediate payment-in-full. more
What happens if ICANN fails? Who will run the DNS then?
Of course to many, ICANN already has failed -- spectacularly so. Critics have long complained that ICANN not only lacks accountability and legitimacy, but also that it is inefficient (at best) and downright destructive (at worst). According to these critics, ICANN's many sins include threatening the stability of the Internet, limiting access by imposing an artificial domain name scarcity, and generally behaving like a petulant dictator. more
In Part I of this article I set the stage for our discussion and overviewed the October 21st DDoS attacks on the Internet's 13 root name servers. In particular, I highlighted that the attacks were different this time, both in size and scope, because the root servers were attacked at the same time. I also highlighted some of the problems associated with the Domain Name System and the vulnerabilities inherent in BIND. Part II of this article takes our discussion to another level by critically looking at alternatives and best practices that can help solve the security problems we've raised. more
