No Honor Among Thieves on the Internet

Apple's Wordwide Developers Conference may have just ended, but already, the conference release of Mac's OS X 10.6 — a beta build previewed for developers — has been leaked onto torrent sites. It borders on irony: for years, Mac lovers have touted the superior security of the Mac operating system over Windows, but earlier this year, it was torrent sites — the very sites where OS X 10.6 is now being freely copied — that caused more than 25,000 Mac users to fall victim to the iServices Trojan. Some Macs never learn. more

Why Not an Interim Step Until DNSSEC is Ready?

I'm interested in CircleID community's take on NeuStar's recent announcement of Cache Defender. While only effective for domains the company is authoritative for, that does cover a large number of big Internet brands and financial institutions. Why wouldn't an ISP deploy this now, while waiting for all the myriad issues involved in DNSSEC to be resolved? more

ICANN 35: What’s Going Down, Down Under (Want the Low Down?)

As I've been getting ready to catch my plane for ICANN 35 (Sydney), I can't help but thinking that there are a lot of things going down these days that will dramatically affect makeup of the Internet for years to come. Next year at this time, the root could be a very, very different place. A few of the items that will be getting deconstructed, discussed, debated Down Under are outlined below... more

Fight Phishing With Branding

Phishing, stealing personal information by impersonating a trusted organization, is a big problem that's not going away. Most antiphishing techniques to date have attempted to recognize fake e-mail and fake web sites, but this hasn't been particularly effective. A more promising approach is to brand the real mail and real web sites. more

DKIM for Discussion Lists

There's a pernicious meme floating around that DomainKeys Identified Mail (DKIM) doesn't work with discussion lists, particularly those hosted on common open source software packages like MailMan. It's particularly odd to see this claim after I set it up successfully on a stock Debian server in less than half an hour, just a few weeks ago. Here's how it can, should, and does work. more

How a Resilient Society Defends Cyberspace

Seventy-five years ago today, on May 29th, 1934, Egyptian private radio stations fell silent, as the government shut them down in favor of a state monopoly on broadcast communication. Egyptian radio "hackers" (as we would style them today) had, over the course of about fifteen years, developed a burgeoning network of unofficial radio stations... It couldn't last. After two days of official radio silence, on May 31st, official state-sponsored radio stations (run by the Marconi company under special contract) began transmitting a clean slate of government-sanctioned programming, and the brief era of grass-roots Egyptian radio was over... more

Thoughts on IPv6 Security, Take Two

A few months ago, I made a post about IPv6 security. I've caught some flak for saying that IPv6 isn't a security issue. I still stand by this position. This is not to say that you should ignore security considerations when deploying IPv6. All I claim is that deploying IPv6 in and of itself does not make an organization any more or less secure. This point was made by Dr. Joe St. Sauver, of the University of Oregon... more

Why DNS Is Broken, Part 2: DoS Target

Before we get into what DNSSEC is and the benefits of it, let's talk about some of the other potential pitfalls of DNS. One of the most significant issues we have to deal with are denial-of-service (DoS) attacks. While DoS attacks are not specific to DNS we have seen DNS be a frequent target of these attacks. more

Hannaford Data Breach Plaintiffs Rebuffed in Maine

A US District Judge in Maine largely granted a motion to dismiss brought by Hannaford in a big data breach case... According to the court, around March 2008, third parties stole up to 4.2 million debit and credit card numbers, expiration dates, security codes, PIN numbers, and other information relating to cardholders "who had used debit cards and credit cards to transact purchases at supermarkets owned or operated by Hannaford." more

Securing a Cloud Infrastructure

George Reese (author of the new book Cloud Application Architectures: Building Applications and Infrastructure in the Cloud) is talking at Gluecon about securing cloud infrastructures. Two recent surveys found "security" was the number one concern of companies considering a move to the cloud. George says the key to making customers comfortable with cloud security is transparency... more
