Sender ID: A Tale of Open Standards and Corporate Greed? - Part II

While everything seemed fine and various participants in these discussions were celebrating the merger of these proposals into one, as well as the support of Microsoft in this endeavor, there was an elephant in the room so to speak, and a rather large one at that. When the original Caller-ID proposal was published, a patent license came along with it. Microsoft indicated that they were planning on filing patents on Caller-ID or some of its aspects, and offered a royalty-free license for the use of their intellectual property. There was some talk about the incompatibility of the license with open source software, including comments from Eben Moglen of FSF and Richard Stallman, but Microsoft employees assured the MARID WG that the licensing issue would be resolved in time for the San Diego meeting. Except that it wasn't.  more

Sender ID: A Tale of Open Standards and Corporate Greed? - Part I

A long long time ago when the Internet was still young and most people were still using clunky Apples, PCs and mainframes; two documents were published by the Advanced Research Projects Agency (ARPA), part of the US Government's Department of Defense. They were called "RFC 821 - Simple Mail Transfer Protocol" and "RFC 822 - Standard for the format of ARPA Internet text messages" respectively. Written by the John Postel and Dave Crocker respectively, often referred to as some of the founding fathers of the Internet, they defined a simple text-based email system for the use of the fledging network then called the "ARPA Internet"... more

Averting the Internet Meltdown

A call to action went out: a small, California-based organization called People for Internet Responsibility (PFIR) posted an announcement for an urgent conference - "Preventing the Internet Meltdown." The meltdown that PFIR envisioned was not an impending technical malfunction or enemy attack. Instead, conference organizers foresaw "risks of imminent disruption" to the Internet that would come from an unlikely sector: government officials and bureaucrats working on the unglamorous-sounding problems of Internet Governance. more

What the ITU WSIS Spam Meeting Accomplished

The first week in July I went to an acronym-heavy World Symposium on the Internet Society Thematic Meeting on spam in Geneva. A few people have reported this as a meeting by "the UN", which it wasn't. Although the International Telecommunications Union is now part of the UN, it dates back to an 1865 treaty to manage international telegraph communication... more

The Site Finder Reprise

I have been attending the Icann conference in Malaysia this week. One of the key events was the submission of the report from the Security & Stability Advisory Committee regarding Site Finder. In reading the committee's report I discovered what I believe is an incredible breakdown in logic and as a consequence, a very mistaken, or at least confused, set of conclusions. So, why do I say that? more

Interview with United Nations Head Secretariat of WGIG

Markus Kummer, Executive Coordinator, Secretariat of the United Nations Working Group on Internet Governance, is a career diplomat, who has served as eEnvoy of the Swiss Foreign Ministry in Bern since April 2002. His main tasks include foreign policy coordination in the area of information and communication technologies, in general, and the World Summit on the Information Society (WSIS), in particular. He chaired the negotiating group that developed an agreed text on Internet governance for the WSIS Declaration of Principles and Plan of Action in December 2003... Mr Kummer says: "The time-frame is very short indeed. And the task ahead of us is daunting." more

The Site Finder Report: Dr. Stephen Crocker, Chair of the Committee

As an advisory committee, our focus is to give ICANN and the community our best advice regarding security and stability issues for the domain name system and the addressing system. We are not a standards, regulatory, judicial or enforcement body; those functions belong elsewhere. As we all know, VeriSign is in the process of suing ICANN on a number of matters, including ICANN's response to their registry change last September. Although VeriSign now contends that a number of us on the committee are "Site Finder co-conspirators" the next steps are really up to the ICANN board, the ICANN staff and the many members of the technical and operating community who run the domain name system. I'll be happy to interact with the members of the community here on CircleID as time permits. more

Privacy Matters: Is It Time To Abolish The WHOIS Database?

Recently, I entered my domain name in a "WHOIS" database query to test the results of the database by using WHOIS on a number of domain name registrar websites. WHOIS is a database service that allows Internet users to look up a number of matters associated with domain names, including the full name of the owner of a domain name, the name of the domain name hosting service, the Internet Protocol or I.P. number(s) corresponding to the domain name, as well as personally identifying information on those who have registered domain names. I was astonished to find... more

Report from UN Spam Meeting in Geneva

The International Telecommunication Union (ITU), held an ITU WSIS Thematic Meeting on Countering Spam from 7 to 9 July 2004, in Geneva, Switzerland. The meeting was focused around various topics including: Scope of the problem, Technical solutions, Consumer protection and awareness, Legislation and enforcement, and International cooperation. The following is a report by William J. Drake, Senior Associate International Centre for Trade and Sustainable Development in Geneva. more

DNS WHOIS: Barking Up the Wrong Tree

As the Internet has grown and matured, it has become obvious to everyone involved that the DNS Whois system, as it currently exists, is not a sustainable way to share contact information for resolving network problems. ICANN, in an attempt to save DNS Whois, has plunged head long into the process of developing new policies aimed at fixing it. While I respect all of the hard work that has gone into this process, the results thus far have only made it clearer that this system faces intractable problems. more

An Interview with the Lead Developer of SPF - Part I

CircleID recently interviewed Meng Weng Wong, the lead developer of Sender Policy Framework (SPF) and founder of Pobox.com. As one of the leading anti spam authentication schemes, SPF is used by companies such as AOL, Earthlink, SAP and supported by anti spam companies such as Sophos, Symantec, Brightmail, IronPort, Ciphertrust, MailArmory, MailFrontier, Roaring Penguin Software, and Communigate Pro. Last month, Microsoft announced its agreement to merge Caller ID, its own proposed anti spam authentication scheme, with SPF -- the joint standard is called 'Sender ID'. In this two-part interview, Meng Wong explains how SPF got started, where it is today and what could be expected in the future of email. more

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. more

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.  more

Email Address Forgery

In my roles as postmaster at CAUCE (the Coalition Against Unsolicited Commercial E-mail) and abuse.net, I get a lot of baffled and outraged mail from people who have discovered that someone is sending out spam, often pornographic spam, with their return address on the From: line. "How can they do that? How do I make them stop?'' The short answers are "easily'' and "it's nearly impossible.'' more

Phone Always Busy? Must be DDoS on VoIP Network

Amidst the fascinating news from the SCO saga, preparing for SANS London and contributing to the Unix timeline project at Grokline my eyes caught a piece of rather distressing news on the BBC. It appears that BT (British Telecom) intends to move its current phone network to an IP-based network by 2009 thereby sending the circuit-switched technology off to the attic. The real question is: can we guarantee the same level of reliability on VoIP as we had on circuit-switched telephony when the stated aim is to carry both voice and data traffic down the same cables (or fibres more likely)? more
