I was talking to my good friend Verner Entwhistle the other day when he suddenly turned to me and said "I don't think we need DNSSEC". Sharp intake of breath. Transpired after a long and involved discussion his case boiled down to four points: 1. SSL provides known and trusted security, DNSSEC is superfluous, 2. DNSSEC is complex and potentially prone to errors, 3. DNSSEC makes DoS attacks worse, 4. DNSSEC does not solve the last mile problem. Let's take them one at a time... more
Mozilla Foundation has announced changes to Firefox concerning Internationalized Domain Names (IDN) to deal with homograph spoofing attacks. According to the organization, "Mozilla Foundation products now only display IDNs in a whitelist of TLDs, which have policies stating what characters are permitted, and procedures for making sure that no homographic domains are registered to two different entities." Following is a statement explaining the current status of the Mozilla changes to Firefox regarding IDN... more
The Internet Corporation for Assigned Names and Numbers (ICANN) has released an "Advisory" concerning VeriSign's deployment of DNS wildcard (Site Finder) service: "Since the deployment, ICANN has been monitoring community reaction, including analysis of the technical effects of the wildcard, and is carefully reviewing the terms of the .com and .net Registry Agreements. In response to widespread expressions of concern from the Internet community about the effects of the introduction of the wildcard..." more
The Intellectual Property Constituency, meeting at the ICANN conference in Vancouver, was interested in increasing ICANN's budget not because they thought they deserved it, but because they wanted ICANN to actually enforce the rules on the books about fake registrations. Now there's some evidence about how prevalent that is. If there's any surprise here, it's that the numbers are so low. more
In modern society, there is one fact that is unquestionable: The hyper-connectivity of the digital economy is inescapable. A financial institution without an online presence or omni-channel strategy will cease to be competitive. Universities (for-profit or non-profit) must develop and continuously evolve their online learning capabilities if they are to stay relevant. Online retailers are quickly outpacing and rendering their 'brick-and-mortar' counterparts irrelevant. more
This is an issue of some concern and should be watched carefully: phishers are now trying to get passwords of domain registrants (domain owners). Currently, correspondents inform me that GoDaddy is the target, but there's no reason to think the phishers won't expand to other registrars. Normally, phishers go after bank accounts or other financial information, or sometimes the online accounts of users so that they may send spam. It's not known precisely why phishers are after domain registration information, but the possibilities are chilling... more
There are some real problems in DNS, related to the general absence of Source Address Validation (SAV) on many networks connected to the Internet. The core of the Internet is aware of destinations but blind to sources. If an attacker on ISP A wants to forge the source IP address of someone at University B when transmitting a packet toward Company C, that packet is likely be delivered complete and intact, including its forged IP source address. Many otherwise sensible people spend a lot of time and airline miles trying to improve this situation... The problems created for the Domain Name System (DNS) by the general lack of SAV are simply hellish. more
Markus Kummer, Executive Coordinator, Secretariat of the United Nations Working Group on Internet Governance, is a career diplomat, who has served as eEnvoy of the Swiss Foreign Ministry in Bern since April 2002. His main tasks include foreign policy coordination in the area of information and communication technologies, in general, and the World Summit on the Information Society (WSIS), in particular. He chaired the negotiating group that developed an agreed text on Internet governance for the WSIS Declaration of Principles and Plan of Action in December 2003... Mr Kummer says: "The time-frame is very short indeed. And the task ahead of us is daunting." more
In mid-March, the group dubbed by Wired Magazine 20 years ago as Crypto-Rebels and Anarchists - the IETF - is meeting in London. With what is likely some loud humming, the activists will likely seek to rain mayhem upon the world of network and societal security using extreme end-to-end encryption, and collaterally diminish some remaining vestiges of an "open internet." Ironically, the IETF uses what has become known as the "NRA defence": extreme encryption doesn't cause harm, criminals and terrorists do. more
It is once again time for our annual review of posts that received the most attention on CircleID during the past year. Congratulations to all the 2017 participants for sharing their thoughts and making a difference in the industry. 2017 marked CircleID's 15th year of operation as a medium dedicated to all critical matters related to the Internet infrastructure and services. We are in the midst of historic times, facing rapid technological developments and there is a lot to look forward to in 2018. more
I have been attending the Icann conference in Malaysia this week. One of the key events was the submission of the report from the Security & Stability Advisory Committee regarding Site Finder. In reading the committee's report I discovered what I believe is an incredible breakdown in logic and as a consequence, a very mistaken, or at least confused, set of conclusions. So, why do I say that? more
If you want to know the world's most dangerous country code Top-Level Domains (ccTLDs), ask an anti-virus software company. McAfee has released its list of most dangerous country codes. Here are the top five... more
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
The new and proposed ICANN registry contracts contain no definite price terms, and thus permit potential tiered pricing on a per domain name basis. This has raised concern within the community that a registry operator might abuse its sole source position to engage in pricing practices detrimental to registrants. ...Notwithstanding the possibility of tiered pricing on a per domain name basis in connection with the recently executed sponsored registry contracts (.MOBI, .JOBS, .TRAVEL, .CAT, and .TEL), there have been numerous comments submitted in connection with this possibility in connection with the proposed contracts for the .BIZ, .INFO and .ORG registry contracts. There were four messages that motivate me to write this article... more
Building IoT ventures from scratch by prototyping hardware devices and their backend systems as well as working for a large company that tries to sell IoT devices itself, we learned a lot about the pitfalls and problems concerning security in the IoT. Nearly every connected device out there proved to be vulnerable to attacks. Researchers showed that it's possible to remotely take control over autonomous vehicles, implanted medical devices were manipulated, voting machines compromised and of course all sorts of other "smart" devices... more
