Warning, Danger Lurks Here: Exploring DKIM/ADSP Edge Cases - Missing message-id

This article is the first in an occasional series on DKIM/ADSP edge cases that may not be generally recognized or understood. Many people advocate DKIM/ADSP adoption without fully recognizing potential implementation and operational issues. The fact is that the email messaging environment is fraught with opportunities for poor outcomes because of common practices that need to be considered or poorly understood implementations that are not considered... more

Minimum Disclosure: What Information Does a Name Server Need to Do Its Job?

Two principles in computer security that help bound the impact of a security compromise are the principle of least privilege and the principle of minimum disclosure or need-to-know. As described by Jerome Saltzer in a July 1974 Communications of the ACM article, Protection and the Control of Information Sharing in Multics, the principle of least privilege states, "Every program and every privileged user should operate using the least amount of privilege necessary to complete the job." more

Government Regulation of Cybersecurity: Partnership (or Power Grab) in the Making?

A cybersecurity bill introduced in the U.S. Senate on April 1st, 2009 would give the United States federal government extraordinary power over private sector Internet services, applications and software. This proposed legislation is a direct result of a review ordered by the Obama administration into government policies and processes for defending against Internet-born attack. The focus of the bill, according to a summary released by the sponsoring senators, is on establishing a new partnership between the public and private sectors in a joint effort to bolster Internet security... more

How Tiered Internet Pricing Could Actually Facilitate P2P

Time Warner Cable's planned experiment with tiered charging for Internet access has generated a flurry of coverage in the blogsphere, but no new insights (at least that I've seen). The primary problem ISP's complain about is that 5% of their customers use 90% of the available bandwidth and when they examine this traffic, it's mostly peer-to-peer file sharing... more

America Will Not Win the Global Race to 5G

Several weeks ago, the White House published a document asserting that "America Will Win the Global Race to 5G." The White House should get over it. This is not about America winning any global race to 5G, but the world working together on fundamentally different, complex, new communication networks and services. There are four important points, however. more

Domain Pulse 2008: Internet Governance the Focus of Day One

Around 350 attendees came from Russia in the east to Ireland in the west, as well as a few people from elsewhere around the globe, to attend Domain Pulse 2008 in Vienna on February 21 and 22. Day one's focus was internet governance. The future of the DNS was one of the key issues addressed by Michael Nelson of Georgetown University in Washington DC, with domain names becoming less important, but their numbers still increasing, as online access by a myriad of devices skyrockets connect -- everything from the television, refrigerator, washing machine, pets, sprinkler systems and cars. more

Is America Getting More Like China?

Since Obama became President -- and yes, I voted for him -- there has been a great deal of optimism and energy around the idea that the Internet can be used to improve or "reboot" our democracy. The Administration has hired some great people to work on making government more open and transparent. This is all great. But how much good will all of this nifty e-government do for American democracy if citizens' rights to privacy and free expression are not also fiercely defended? more

Musings on Metering: An Update from ICANN’s Latest Meeting

ICANN held another update for new gTLD applicants last week, revealing that the proposal to meter the introduction of new gTLDs received many suggestions during the open comment period. This was just the first step to what I imagine will be a long process - one that will continue on September 12 when ICANN holds a public consultation that will offer more detailed discussion on the many different options for metering. more

New gTLDs: Money Maker

There are fascinating ideas about how, when and more than everything: who is going to earn money from gTLDs? I think back-end registry providers will earn money, some applicants will earn money too but my experience launching Eurid, the registry for .EU, reminded me one thing: these days, just before launching, until the (first) Sunrise period is launched. more

The Myth of Population Density and the High Cost of Broadband

One of the enduring myths that is used by apologists for incumbent broadband operators as to the high cost of broadband in Canada and the US is our low population density.
Since Canada and the US have low population density compared to The Netherlands or South Korea, they argue that therefore the cost of delivering broadband will be significantly higher because of the much greater distances that need to be covered. more

New Technique Detects and Eliminates Abusive Domains at Time of Registration

A team of researchers from Princeton University and the University of California has developed a machine-learning algorithm named PREDATOR that can accurately establish domain reputation at the time of domain registration. more

AfPIF 2016 Diaries: 7th African Peering and Interconnection Forum

The 7th African Peering and Interconnection Forum (AfPIF) took place in Dar es Salaam, Tanzania, from 30 August - 1 September 2016. AfPIF is the annual conference organised by the Internet Society to specifically address interconnection challenges together with the wide-ranging opportunities the African continent offers. Tanzania is well-known for its safari, Mount Kilimanjaro and beautiful Zanzibar beaches, but not only that... more

The Trademark Clearinghouse: Secure, Reliable, Usable - Pick Any Two

Earlier this week, technical and legal experts from ICANN, Deloitte and IBM met in Brussels with their counterparts from registrars and registry service providers representing as much as 90% of prospective gTLD registries, to discuss the technical implementation of the Trademark Clearinghouse, the database of rights holder information that will support the mandatory rights holder protection mechanisms for new gTLDs. more

Exporting SOPA-Like Rules to Other Countries

"While SOPA may be dead (for now) in the U.S., lobby groups are likely to intensify their efforts to export SOPA-like rules to other countries," says Michael Geist in a blog post today. Geist writes: "With Bill C-11 back on the legislative agenda at the end of the month, Canada will be a prime target for SOPA style rules. In fact, a close review of the unpublished submissions to the Bill C-32 legislative committee reveals that several groups have laid the groundwork to add SOPA-like rules into Bill C-11 ..." more
