There Is No "Spam Problem"

This month I thought I could feel smug, deploying Postfix, with greylisting (Postgrey), and the Spamhaus block list (SBL-XBL) has reduced the volume of unsolicited bulk commercial email one of our servers was delivering to our clients by 98.99%. Alas greylisting is a flawed remedy, it merely requires the spambots to act more like email servers and it will fail, and eventually they will... more

Identity Theft: Giving Away Your Personal Information

Identity theft is apparently the "in thing" these days. By media accounts, hackers and evildoers lurk everywhere trying to steal your personal information. In the past few months, one company after another is being forced to admit customer data has been lost or stolen. In many cases, they have them come forth repeatedly over the next few weeks, or even months revising the estimated number of impacted customers. To date, I don't think any have ever lowered those numbers. ...Let's consider two events that didn't make the front page of C|Net or CNN.  more

Road Warrior at Risk: The Dangers of Ad-Hoc Wireless Networking

Most people who have wireless Ethernet at home, or the office, connect to the wireless network by attaching to a wireless Access Point, or AP. This method of wireless networking is called "Infrastructure Mode". If you have a secure wireless network configured in "Infrastructure Mode" you are using MAC address filtering, some level of encryption, and have made some additional changes to your AP in order to prevent just anyone from using it or capturing data. ...However, for those who are not using "Infrastructure Mode", and are configured to communicate from machine to machine, or "Ad-Hoc", there are a few things you should be aware of. more

Study Finds Spammers Use P2P Harvesting to Spam Millions

A recent study conducted by Blue Security reports how Internet users can unknowingly expose their contacts' emails addresses to Spammers while sharing files, music, games and DVDs over Peer-to-Peer (P2P) networks. The study has uncovered hundreds of incidents where files containing email addresses were made accessible in P2P networks. more

URLs: Ontologically Speaking

I was reading David Weinberger's reports on how the New York Times is planning on tackling its "link rot" problem where articles slip behind the pay-wall. Part of their solution appears to be to replace articles with their summaries. As usual, this got me thinking about telephony. Why don't phone calls and callers have URIs or URLs? ...Let's take addressing the endpoints first. Obviously, ENUM is one way of "Internetising" the phone number address space. more

Internet Governance: Analogue Solutions to Digital Problems

This is an overview of the booklet, "Internet Governance: Issues, Actors and Divides," recently published by DiploFoundation and the Global Knowledge Partnership. "Internet Governance is not a simple subject. Although it deals with a major symbol of the DIGITAL world, it cannot be handled with a digital - binary logic of true/false and good/bad. Instead, the subject's many subtleties and shades of meaning and perception require an ANALOGUE approach, covering a continuum of options and compromises." Update: This article was reposted with additional information and a new title. 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

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

U.S. Moving Forward with ENUM

One of the pieces of infrastructure that makes all kinds of networks work and yet gets very little attention is the directory. Directories are big business. For example, there's directory of telephone numbers run by NeuStar, Inc. NeuStar has annual revenues of $92 million. Now, according to Light Reading, AT&T Corp. and MCI Inc., together with unidentified cable companies, telephone companies, and ISPs are preparing to form a Limited Liability Corporation (LLC) that will run a process to define a new company that will run ENUM. more

New Mobile Domain Another Bad Idea

You may have seen a new proposal for a "mobile" top-level domain name for use by something called "mobile users" whatever they are. (The domain will not actually be named .mobile, rumours are they are hoping for a coveted one-letter TLD like .m "to make it easier to type on a mobile phone.) Centuries ago, as trademark law began its evolution, we learned one pretty strong rule about building rules for a name system for commerce, and even for non-commerce.
Nobody should be given ownership of generic terms. Nobody should have ownership rights in a generic word like "apple" -- not Apple Computer, not Apple Records, not the Washington State Apple Growers, not a man named John Apple. more
