Centralizing the Net, Monetizing DNS, Getting Trendy?

In a Red Herring Conference held last week in California, Mitch Ratcliffe's offers an analytical overview of an interview held with Stratton Scalovs, VerisSign's CEO..."He then goes on to say that we need to move the complexity back into the center of the Net! He says the edge can't be so complex. Get David Isenberg in here! Ross Mayfield, sitting in front of me, laughs out loud. I am dumbfounded. According to VeriSign, the Net should not be open to any type of application, only applications that rely on single providers of services, like VeriSign. This is troglodyte talk."

ICANN, WSIS and the Making of a Global Civil Society - Part II

This is the second part of a two-part series interview by Geert Lovink with Milton Mueller discussing ICANN, World Summit on the Information Society, and the escalating debates over Internet Governance. Read the first part of this Interview here. Geert Lovink: "Confronted with Internet governance many cyber activists find themselves in a catch 22 situation. On the one hand they do not trust government bureaucrats to run the Internet, out of a justified fear that regulation through multilateral negotiations might lead to censorship and stifle innovation. On the other hand they criticize the corporate agendas of the engineering class that is anything but representative. What models should activists propose in the light of the World Summit on the Information Society (WSIS)? There seems to be no way back to a nation state 'federalist' solution. Should they buy into the 'global civil society' solution?"

.Name Registry Hacked

On Saturday, November 29, 2003 a post on the GNSO mailing list indicated that the .name registry website had been hacked. As reported by George Kirikos, "The .name registry's main website www.nic.name has been hacked, as of Saturday evening in North America. According to Netcraft, they're running Linux. They must not have kept up to date with all security updates, or someone cracked a password. Hopefully offsite backups were made, to ensure data integrity." Although, due to this emergency, the .name web servers have been pulled down as of this writing, just a short few hours ago, visitors to the .name registry home page would find a mysterious black screen upon visiting the site, including the following text...

VeriSign’s New Security Seal Too Trusting?

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!

Blacklisting Under Wrong Assumptions

If you analyze the relay of spam- and malware-containing email circulating on the Internet purely through your mail server logs (running the Unix command "tail"), a large proportion seem to come from Asia Pacific hosts, especially those from mainland China. Therefore, many less-experienced systems administrators have simply blocked the access from subnets of Chinese or Asian origin, effectively destroying the fabric of the Internet -- messaging. If administrators took pains to analyze these supposedly Asian spam messages by analyzing the full Internet headers, they would have realized that the Asian servers were merely used by the real spammers as open relays, or perhaps as zombie hosts previously infected with the mass mailing worms through the exploitation of operating system vulnerabilities.

The Future of Email

While people may debate the death of email, there is no question that many email servers are already overloaded with spam. Current spam solutions are beginning to address the problem, but so far they all suffer from the arms race issue - as fast as we come up with new ways to fight spam, spammers are finding new ways to deliver it to us. While the functionality of email will certainly continue, the current system must change. When the change comes, it will deliver the future of email to Microsoft.

NAT: Just Say No

Fueled by the lack of public IP addresses, 70% of Fortune 1000 companies have been forced to deploy NATs (Source: Center for Next Generation Internet). NATs are also found in hundreds of thousands of small business and home networks where several hosts must share a single IP address. It has been so successful in slowing the depletion of IPv4 addresses that many have questioned the need for IPv6 in the near future. However, such conclusions ignore the fact that a strategy based on avoiding a crisis can never provide the long-term benefits that solving the underlying problems that precipitated the crisis offers.

DNS Gets A Formal Coordination System

CircleID recently interview Paul Vixie, Founder & Chairman of Internet Software Consortium (ISC), to discuss ISC's newly formed Operations, Analysis, and Research Center (OARC). OARC is launched in response to DDoS attacks at the Internet's core infrastructure and the vital requirement for a formal coordination system. OARC is also a part of US homeland security initiatives, such as the formation of Information Sharing and Analysis Centers (ISACs).

"Registries and registrars, ccTLD operators, large corporate NOCs, ISPs and ecommerce companies that host many domain names are all likely candidates. This is also a natural for law enforcement groups that are worried about attacks on the Internet."

SECSAC Special Meeting on Site Finder: A Technical Analysis

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.

Reaction to VeriSign’s New 36-Hour Deadline

ICANN today has made a formal demand stating: "Given the magnitude of the issues that have been raised, and their potential impact on the security and stability of the Internet, the DNS and the .com and .net top level domains, VeriSign must suspend the changes to the .com and .net top-level domains introduced on 15 September 2003 by 6:00 PM PDT on 4 October 2003. Failure to comply with this demand by that time will leave ICANN with no choice but to seek promptly to enforce VeriSign's contractual obligations." What follows is a collection of commentaries made around the net and by experts in response to today's announcement...
