Syrian Internet Shutdown

James Cowie from Renesys reports: "Starting at 3:35 UTC today (6:35am local time), approximately two-thirds of all Syrian networks became unreachable from the global Internet. Over the course of roughly half an hour, the routes to 40 of 59 networks were withdrawn from the global routing table." more

ICANN Releases gTLD Applicant Guidebook

Per their timeline, ICANN released the gTLD Applicant Guidebook on May 30th. This version contains revisions based upon both community feedback, as well as recent consultations with the Governmental Advisory Committee (GAC). more

The ICANN Accountability and Transparency Review Team Recommendations: To Implementation, And Beyond

Buzz Lightyear, the astronaut character from the movie Toy Story, is known for his tagline, "To infinity, and beyond!" ICANN can take a lesson from the ebullient Buzz with respect to accountability and transparency. Just as Buzz believed he could fly beyond infinity, ICANN should view full implementation of the Accountability and Transparency Review Team (ATRT) recommendations not as the last stop, but as the next stop on its important journey of accountability and transparency. more

IP Addresses as Money

It's no secret that the supply of IPv4 addresses, on which the Internet has been based since the dawn of digital time, is rapidly running out. The official replacement is much larger IPv6 addresses, but I can report from experience that the task of switching is not trivial, and for a long time there will be a lot of the net that's only on IPv4. So once the initial supply of IPv4 addresses run out, and the only way to get some is to buy them from someone else, what will the market be like? more

The Ugly End of the Phone Network

I was a little early. "By the end of President Obama's first term, there won't be any more copper landlines left in the country, I blogged just after Obama had been elected. Before that I'd prophesized the end of POTS (Plain Old Telephone Service) by 2010. Nevertheless, the end is nigh. And it's gonna be ugly without some planning. more

The ENISA Botnet Report: Thoughts on the State of Play in Smart Phones

At the ENISA presentation on her botnet report at eco in Cologne, 9 and 10 March, one of the slots was dedicated to threats to the mobile environment. The message I was supposed to come home with was: we can still count the numbers of mobile viruses manually, <600; the problem will never be the same as on a fixed network as traffic is monitored and metered: We detect it straight away. We are studying the problem seriously. Are mobile operators really prepared for what is coming? more

Open letter to US House Subcommittee for Oversight Hearing on gTLDs

This is an open letter to the United States House Subcommittee on Intellectual Property and the Internet regarding the Oversight Hearing on new Top-Level Domains to be held on Wednesday 4 May. The intention of the open letter is to highlight the imbalance of intellectual property interests on the panel and to ensure the Subcommittee is presented with some balanced facts and benefits of the new Top-Level Domain program. more

Report on Smart Grid Cyber Security

A recent report from Pike Research, "Smart Grid Cyber Security" has found if smart grids can realize their full potential, consumers, utilities, nations, and even the earth itself will benefit. As with nearly any new technology, the industry focus has been on getting smart grids up and running, often with little consideration for cyber security issues. more

Password Policies Need to Be the Same if We Want Users to Take Our Advice

The other day on Facebook, one of my friends mentioned that today (i.e., that day) was a good day to update his passwords. But he then lamented that some web sites don't allow you to create more than a 12-character password! He was incensed! Well, maybe not incensed but showed contempt for the fact these sites restricted password length. more

Defending Against the Hackers of 1995

Two factor authentication that uses an uncopyable physical device (such as a cellphone or a security token) as a second factor mitigates most of these threats very effectively. Weaker two factor authentication using digital certificates is a little easier to misuse (as the user can share the certificate with others, or have it copied without them noticing) but still a lot better than a password. Security problems solved, then? more

What Next for Email Service Providers?

It's been a very bad month for ESPs, companies that handle bulk mailings for their clients. Several of them have had internal security breaches, leaking client information, client mailing lists, or both. Many have also seen clients compromised, with the compromised credentials used to send spam. The sequence of events suggests all the ESPs whose clients were compromised were themselves compromised first. (That's how the crooks knew who to attack.) more

Court Approves Nortel’s Sale of IPv4 Addresses to Microsoft

Yesterday morning (26-April-2011), in US Bankruptcy Court for the District of Delaware, Judge Kevin Gross signed an order authorizing Nortel's sale of IPv4 addresses to Microsoft. This is an important moment for the Internet community, as it represents the beginning of a new market-based mechanism for the distribution of scarce IPv4 address resources. As the various Regional Internet Registry (RIR) organizations exhaust their supply, traditional "needs-based" distribution will become impossible. more

Really? A Hearing on New gTLDs at this Late Stage?

To the dismay of many (and the chagrin of some), it appears as though the US House Subcommittee on Intellectual Property, Competition and the Internet will be conducting a hearing on New generic Top-Level Domains (gTLDs). Meanwhile, ICANN is careening towards the finish line of the new gTLD Program with a vote by the ICANN Board scheduled for June 20th. Just what this all means remains to be seen. more

Top 3 New Requirements to the TLD Evaluation Criteria and What They Mean for Applicants

Three sections of the redlined version of the Draft Evaluation Criteria for new Top-Level Domains (TLDs) caught my attention. It seems ICANN wants to ensure it has information to not only evaluate and score responses, but to conduct a post-launch analysis of the program's success in terms of expanded competition, consumer choice and trust. That additional information means more work by both the applicant and for ICANN. But it's a good move because pre-launch preparation and thought staves off mishaps and misfortunes later. more

7 Must Have Attributes of an IP Address Management System

Exponential growth of networks combined with the complexity introduced by IT initiatives e.g. VoIP, Cloud computing, server virtualization, desktop virtualization, IPv6 and service automation has required network teams to look for tools to automate IP address management (IPAM). Automated IPAM tools allow administrators to allocate subnets, allocate/track/reclaim IP addresses and provide visibility into the networks. Here are some examples of what a typical IPAM tool can do... more
