The US Department of Commerce, the DNS Root, and ICANN

The recent announcement in eWeek titled "Feds Won't Let Go of Internet DNS" (slashdotted here) has some major internet policy implications. The short, careful wording appears to be more of a threat to ICANN than a power grab. In short, the US Department of Commerce's (DOC) National Telecommunications and Information Administration (NTIA) announced that it was not going to stop overseeing ICANN's changes to the DNS root. ...Of course, they have done next to nothing to support DNSSEC or other proposal for securing the DNS, but it sounds reassuring. The last sentence shows that the Bush administration shares the Clinton administration's lack of understanding of how the internet should evolve... more

U.S. Government to Retain Oversight of the Internet’s Root Servers

The U.S. government has announced today that it will indefinitely retain oversight of the Internet's root servers, ignoring pervious calls by some countries to turn the function over to an international body. more

Twenty Myths and Truths About IPv6 and the US IPv6 Transition

After hearing over 350 presentations on IPv6 from IPv6-related events in the US (seven of them), China, Spain, Japan, and Australia, and having had over 3,000 discussions about IPv6 with over a thousand well-informed people in the IPv6 community, I have come to the conclusion that all parties, particularly the press, have done a terrible job of informing people about the bigger picture of IPv6, over the last decade, and that we need to achieve a new consensus that doesn't include so much common wisdom that is simply mythical. There are many others in a position to do this exercise better than I can, and I invite them to make a better list than mine, which follows. more

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

Some Notes on the .XXX Top-Level Domain

Yesterday the ICANN board discussed and approved ICANN staff to enter into negotiations with ICM Registry, Inc. for the .XXX Top Level Domain (TLD). I'm sure there will be a longer more complete presentation from ICANN later about this, but as an individual board member I thought I'd post a quick note before people got carried away with speculation based on a lack of information. more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

Actions Required by Developing Economies Against Spam

My OECD paper on spam problems in developing economies is now linked from the OECD Anti-Spam Toolkit page, as part of section 8 of the Anti-Spam Toolkit (Outreach). This ZDNet article provides a reasonably good summary of my paper as well. I welcome comments and suggestions from CircleID readers. "Spam is a much more serious issue in developing countries as it is a heavy drain on resources that are scarcer and costlier in developing countries than elsewhere..." more

Crack the Code: That’s a Direct Challenge

I had quite an interesting experience recently. I was hired by a company to perform a vulnerability assessment and penetration test on their network. During the initial meeting, one of the key technical staff presented me with a challenge; He handed over the NTLM hash of the domain Administrator account and challenged me to decipher it. He explained that the complexity and length of the password would prevent me from deciphering it during the time allotted for the project. He was actually quite confident in my impending failure... more

New Study Revealing Behind the Scenes of Phishing Attacks

The following is an overview of the recent Honeynet Project and Research Alliance study called 'Know your Enemy:Phishing' aimed at discovering practical information on the practice of phishing. This study focuses on real world incidents based on data captured and analyzed from the UK and German Honeynet Project revealing how attackers build and use their infrastructure for Phishing based attacks. "This data has helped us to understand how phishers typically behave and some of the methods they employ to lure and trick their victims. We have learned that phishing attacks can occur very rapidly, with only limited elapsed time between the initial system intrusion and a phishing web site going online..." more

ICANN Call for Submissions of Interest for Leadership

ICANN's Nomination Committee has begun their process to nominate more members to various boards, councils and committees of ICANN. This is the process by which I was elected to the board last year. Contrary to what some people may think, these positions should not be taken to try to gain some privilege or power. These are positions of responsibility and require a lot of work for no tangible return except possibly the opportunity to meet other very interesting people. I think about my role at ICANN like I would think about jury duty. We have all benefited from the proper functioning of the Internet for the last decade. If you've benefited in the past and care about the future of the Internet, it is a great opportunity to give back to the community by applying for one of these positions. more
