Thoughts About “Protection Against BIND”

Imagine my surprise upon reading a BBC article which identified ISC BIND as the top security vulnerability to UNIX systems. At ISC, we have striven for a decade to repair BIND's reputation, and by all accounts we have made great progress. "What could this be about," I wondered, as I scanned the BBC article for more details. It turns out that BBC was merely parroting what it had been told by SANS. OK, let's see what SANS has to say... more

Google Buys VeriSign (not really)

No that's not really happening, Google is not buying VeriSign. But given Google's ravenous appetite for data, it might find VeriSign quite attractive. VeriSign has both root domain name servers and servers for the .com and .net top level domains (TLDs). VeriSign could data mine the queries coming into those servers and produce a very valuable real-time stream of what users on the net are doing... Google just bought Postini -- and one would have to be fairly naive to believe that Google does not intend to dredge through all... more

The End of the (IPv4) World is Nigher!

Funny how some topics seem sit on a quiet back burner for years, and then all of a sudden become matters of relatively intense attention. Over the past few weeks we've seen a number of pronouncements on the imminent exhaustion of the IP version 4 address pools. Not only have some of the Regional Internet Registries (RIRs) and some national registry bodies made public statements on the topic, we've now seen ICANN also make its pronouncement on this topic... Why the sudden uptake of interest in this topic? I suspect that a small part of this may be my fault! more

The New Hong Kong Anti-Spam Law, and a Small Fly in the Ointment

Well, it has been quite a while since first the Hong Kong OFTA (in 2004) and then CITB (in 2006) issued requests for public comment about a proposed UEM (Unsolicited Electronic Messaging) bill to be introduced in Hong Kong, for the purpose of regulating unsolicited email, telephone and fax solicitations. We're a large (worldwide) provider of email and spam filtering - but we're based in Hong Kong, and any regulation there naturally gets tracked by us rather more actively than laws elsewhere. We sent in our responses to both these agencies... The bill is becoming law now - and most of it looks good... There's one major fly in the ointment though... more

Will Arrest Stem Tide of Spam?

Legitimate email marketers, anti-spam groups and beleaguered recipients got a bit of good news with the arrest last week of a man described as one of the world's most prolific spammers. Robert Alan Soloway, 27, dubbed "the Seattle Spammer" by federal officials, was indicted on 35 charges related to fraudulent Internet activities. Soloway pleaded not guilty to all charges at his May 30 arraignment. You can read more here. Although it's always great when a notorious spammer gets put out of business, such actions probably won't result in a drop in the amount of spam that gets sent... more

Commercial DNSSEC?

Seems that DNSSEC is being subjected to what an old boss of mine used to call the "fatal flaw seeking missiles" which try to explain the technical reasons that DNSSEC is not being implemented. First it was zone walking, then the complexity of Proof of Non-Existence (PNE), next week ... one shudders to think. While there is still some modest technical work outstanding on DNSSEC, NSEC3 and the mechanics of key rollover being examples, that work, of itself, does not explain the stunning lack of implementation or aggressive planning being undertaken within the DNS community. more

Discussion at the Internet Governance Forum in Geneva

While travelling home from Geneva, I was thinking quite a lot on the relationship between a ccTLD (registry) and a Country. This is because many countries are starting to talk louder and louder about the responsibilities Countries have on critical infrastructure, or (possibly more important) the management of the critical infrastructure. Will for example any (none?) of ccTLD operators (servers) sustain a denial of service attack of a scale similar to the attack on the root servers? What can ccTLD operators do to resist the malicious attacks? Should this be discussed? more

IGF Preparatory Meeting: A Score Draw in Geneva

Wednesday was the open public consultation preparing for the second meeting of the Internet Governance Forum, which will take place in Rio de Janaeiro on 12th-15th November. Although the inaugural Athens meeting was widely deemed a success, having largely stayed off the dread topics of wresting control of DNS from ICANN and IP addressing from the RIRs, the usual suspects were back demanding that these topics be added to the agenda. more

Book Review: Sex.com by Kieren McCarthy

On the face of it, Kieren McCarthy's Sex.com was a book that could have written itself: a notorious, well-publicised feud over the most valuable domain name in existence, between two charismatic men -- one a serial entrepreneur with a weakness for hard drugs (Gary Kremen), the other a gifted con-man with delusions of grandeur (Stephen Cohen). It's a story replete with vicious acrimony, multi-million dollar lawsuits, and rumours of gunfights between bounty hunters in the streets of Tijuana. Thankfully, McCarthy wasn't content to just bundle together all the articles he's written about Sex.com over the years and slap a cover on the front... more

Why I Voted for .XXX

The ICANN Board voted today 9-5, with Paul Twomey abstaining, to reject a proposal to open .xxx. This is my statement in connection with that vote. I found the resolution adopted by the Board (rejecting xxx) both weak and unprincipled... I am troubled by the path the Board has followed on this issue since I joined the Board in December of 2005. I would like to make two points. First, ICANN only creates problems for itself when it acts in an ad hoc fashion in response to political pressures. Second, ICANN should take itself seriously as a private governance institution with a limited mandate and should resist efforts by governments to veto what it does. more

Put Security Alongside .XXX

Isn't security as important to discuss as .XSS? The DNS has become an abuse infrastructure, it is no longer just a functional infrastructure. It is not being used by malware, phishing and other Bad Things [TM], it facilitates them. Operational needs require the policy and governance folks to start taking notice. It's high time security got where it needs to be on the agenda, not just because it is important to consider security, but rather because lack of security controls made it a necessity. more

Please, Keep the Core Neutral

Many in the technical community attribute the rapid growth and spread of the Internet to innovation that took place at the "edge" of the network, while its "core" was left largely application neutral to provide a universal and predictable building block for innovation. It is this core neutrality that provides a basis for the security and stability of the Internet as a whole. And it is this same core neutrality that is critical to the continued spread of the Internet across the Digital Divide. Unfortunately, when the politics of censorship rather than solely technical concerns drive the coordination of these "core" Internet resources, it threatens the future security and stability of the Internet. This paper proposes a paradigm upon which all the governments of the world have equal access to these core Internet resources to empower them and their citizens with the rights acknowledged in the WSIS Declaration of Principles. more

.COM and .NET: Thick Or Thin?

The fallout from the failure of RegisterFly has been largely addressed as an issue of regulation and enforcement. ...ICANN has not historically enforced the escrow obligation, and in any case, if a company has failed, who exactly is going to take responsibility for updating the escrowed data? It seems to me that the problems that have arisen as a result of RegisterFly's collapse have more to do with the design of the "shared registry system" for the .COM and .NET TLDs than they do with ICANN's failure to enforce the RAA. more

Ongoing Internet Emergency and Domain Names

There is a current ongoing Internet emergency: a critical 0day vulnerability currently exploited in the wild threatens numerous desktop systems which are being compromised and turned into bots, and the domain names hosting it are a significant part of the reason why this attack has not yet been mitigated. This incident is currently being handled by several operational groups. This past February, I sent an email to the Reg-Ops (Registrar Operations) mailing list. The email, which is quoted below, states how DNS abuse (not the DNS infrastructure) is the biggest unmitigated current vulnerability in day-to-day Internet security operations, not to mention abuse. more

ITU Launches IDN Survey and ccTLD Outreach

Today, the ITU launched a new survey asking member states, ccTLDs and other ITU member organizations to provide answers to a specialized questionnaire asking for their experiences on the use of IDNs. The ITU states that it is reaching out to ccTLDs to "collect information and experiences on Internationalized Domain Names under ccTLD (country code Top Level Domain) around the globe." One of the goals of this survey is to collate information on the "needs and practices" of each ccTLD that is surveyed -- so as to compile a report from the ITU that speaks to the implementation of IDNs around the world... more
