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

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

Internet Governance: There Are No Masterplans

Please pardon me if I start this story by telling about an incident that happened to me at the Madrid airport while flying to the ICANN meetings in Rio.

It was about midnight when, after flying in from Turin, my hometown, I had to go through the passport control to reach my gate for the flight to Rio. The war between the US/UK and Iraq had started two days before, and even if the Spanish government was among its supporters, security checks were apparently proceeding as usual. Passport controls inside the EU for EU citizens usually take a few seconds, and the line ahead of me was proceeding quickly. 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

Registration Patterns of Deceptive Domains

A key requirement for a bad actor wanting to launch a brand attack is the registration of a carefully chosen domain name. The most convincing infringements frequently use a domain name that's deceptively similar to that of the official site of the target brand. This allows a variety of attacks to be executed, including phishing attacks... more

Brazil: The Newest Up and Comer

The Virus Bulletin Conference last month had some good presentations, including this one by Fabio Assolini of Kaspersky. He spoke about how Brazil is the the newest up-and-comer on the cyber crime block. The tale begins with the story of Igor and Emily, two cyber criminals operating out of Brazil. Together, the two of them stole $300,000 US from a single Brazilian bank in one year. 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

The Cycle of E-Mail Security

Stepping back from the DMARC arguments, it occurs to me that there is a predictable cycle with every new e-mail security technology... Someone invents a new way to make e-mail more secure, call it SPF or DKIM or DMARC or (this month's mini-fiasco) PGP in DANE. Each scheme has a model of the way that mail works. For some subset of e-mail, the model works great, for other mail it works less great. more

Lake City became the second Florida city to pay a substantial ransomware demand to hackers in less than a week. more

Dotless Domains Considered Harmful, Says IAB

In light of recent controversies around the implementation of dotless domains, the Internet Architecture Board (IAB) has released a statement calling the practice harmful. From the executive summary: "It has come to the attention of the IAB that there are proposals for so-called "dotless" domains in the root zone, and that some existing top-level domains (TLDs) are already operating in such a mode. TLD operators of dotless domains are intending that single label names -- those containing no dots -- resolve to the TLD itself, rather than be resolved locally, within the context of the local site at which the user resides." more

Death and Your Online Identity

How large is your digital footprint? If you pulled together your email account, web site, blog, social networking accounts, and every other virtual identity you have online, just how well known are you on the Internet? Have you ever stopped to consider what happens to your online identity when you die? How would your online friends know? What would happen to your accounts and your content? more
