Examining Two Well-Known Attacks on VoIP

VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments.

ENUM: Mapping the E.164 Number Space into the DNS

Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case...

Telecom Policy Review Panel Calls For Net Neutrality Legal Safeguards

The Telecommunications Policy Review Panel report [Canada] was released yesterday and while the immediate reaction will no doubt focus on the recommendations for a market-oriented approach with significant changes to the CRTC, I would call attention to three other recommendations gleaned from reading the executive summary (the full document is nearly 400 pages).

Examining the Reality of Convergence

If there is one word in the telecommunications that has suffered from over-abuse for many years now, it's convergence. The term has been liberally applied to each successive generation of communications technology for their supposed ability to solve a myriad of service delivery problems within a single unifying converged carriage and service delivery solution. Unfortunately, the underlying reality has always been markedly different from these wondrous promises, and we continue to see an industry that deploys a plethora of service delivery platforms and an equally diverse collection of associated switching and service delivery technologies. One can't help but wonder at the collective gullibility of an industry that continues to herald the convergent attributes of each new generation of communications technology, while at the same time being forced to admit that previous convergent promises have never been realized.

She Gave Me a Fake Phone Number!

The Intellectual Property Constituency, meeting at the ICANN conference in Vancouver, was interested in increasing ICANN's budget not because they thought they deserved it, but because they wanted ICANN to actually enforce the rules on the books about fake registrations. Now there's some evidence about how prevalent that is. If there's any surprise here, it's that the numbers are so low.

How to Listen to the Individual Internet User

The recent ICANN meeting in Vancouver touched upon many issues important to ordinary Internet users: privacy in domain name registration; the cost and terms of .com domain names; internationalized domains; introduction of new domain suffixes. But there were few "ordinary Internet users" at the meeting. Few people can roam the globe to keep up with ICANN's travels, and not many more participate in online forums.

Nom-Com Appoints Independent and Diverse Candidates to ICANN Leadership Positions

When 72 candidates vie for 8 positions, making tough choices are inevitable. ICANN's 2005 Nominating Committee (Nom-Com) on Friday announced the selection of a diverse and independent set of nominees for important roles in ICANN, including the Board of Directors, the Generic Names Supporting Organization (GNSO), the At-Large Advisory Council (ALAC) and the Country Code Names Supporting Organization (ccNSO).

Whither DNS?

The Domain Name System is often though of as an integral part of the Internet. Without it, how can you ever locate anything? Well, quite easily, thank you very much. DNS is used implicitly for many services, such as web browsing. It also includes explicit extensions for a few applications such as e-mail. (I'm talking here about DNS the system, not DNS the technology that can be re-purposed to things like ENUM.) But the most notable thing about DNS is its receding importance...

Regime Change on the Internet: Conference Notes

"Regime Change on the Internet? Internet Governance after WGIG" was the first public event held in the United States on July 28, 2005 to review the UN Working Group on Internet Governance (WGIG) report. Here are my notes from the event: "Markus Kummer, Executive Coordinator, UN Working Group on Internet Governance, reminded the audience that the mandate of the WGIG was specifically articulated by the first part of the WSIS - "To investigate and make proposals for action as appropriate". It was not for sweeping regime change as the conference title would suggest."

A Balkanized Internet Future?

Joi Ito has an important post [also featured on CircleID] on how the internet is in danger of becoming balkanized into separate "internets". He's not the only person who's concerned. Greg Walton worries about Regime Change on the Internet. My friend Tim Wu, a law professor specializing in international trade and intellectual property, has written an article for Slate: The Filtered Future: China's bid to divide the Internet...
