Cyber Threats Yes, But Is It Cyber War?

Last night Intelligence Squared and Neustar conducted a fascinating, Oxford style debate on whether the threat of cyber war has been exaggerated. A packed house at the Newseum in Washington, DC heard four cyber heavyweights go toe-to-toe verbally both for and against the proposition that the threat has been exaggerated. more

The [Dot]Brand Tribes - Part 3

In part two of The [Dot] Brand Tribes we argued that introducing new branded generic Top-Level Domains (gTLDs) would bring value to brand owners and have positive effects on customer recognition. In this last post we'll continue that theme and talk about how brand owners can come together to provide shared spaces using the banking industry as an example. more

Preventing DNS Strain When You Deploy DNSSEC

The barriers to DNSSEC adoption are quickly disappearing. There are nearly 20 top-level domains that have already deployed DNSSEC including generic TLDs like .org and .gov. This July, the DNS root will also be signed, and will begin validating. At this point, the decision for remaining TLDs to deploy DNSSEC is really no longer a question. more

Who is Blocking WHOIS?

On April 16 ICANN issued a breach notice to Turkish Registrar Alantron for not consistently providing access to its WHOIS database via Port 43, a command-line query location that all Registrars are required to supply under conditions of their contract with ICANN under section 3.3.1. Four days later they issued a breach to Internet Group do Brazil for the same problem. ... The WHOIS record, as we all know, is a massive fraud with illicit parties filling records with bogus information and hiding behind anonymity. more

Registrar Abacus America is in Corporate Delinquency

KnujOn has retrieved a document indicating that the ICANN-Accredited Registrar Abacus America is in Corporate Delinquency in the state of Kansas. Kansas defines a company as Delinquent if "The business entity has not filed its annual report and fee by the due date." ...

Deploying DNSSEC: Lessons from Domain Registrar Implementation

As a registrar at the front end of the DNSSEC deployment effort, our technical team has made a sustained investment in DNSSEC deployment so that our customers don't get overwhelmed by this wave of changes to the core infrastructure of the Domain Name System. Along the way, we've learnt a lot about how to implement DNSSEC which might hold useful lessons for other organizations that plan to deploy DNSSEC in their networks. more

VeriSign Leaves the Security Certificate Business

Earlier this week in a press release, VeriSign said that they are selling their SSL certificate business to Symantec. VeriSign is the dominant player in this market, having absorbed competitor Thawte in 1999, and Geotrust in 2006. Three years ago, when VeriSign decided to divest its non-core businesses, they kept the certificate business. So what's changed? more

The Extent of DNS Services Being Blocked in China

The most recent episode of The Ask Mr. DNS Podcast offers up some disturbing corroborating evidence as to the extent of DNS filtering and outright blocking occurring in China. VeriSign's Matt Larson and InfoBlox's Cricket Liu, who co-host the geeky yet engaging and extremely informative show, held a roundtable discussion including technical experts from dynamic name service providers (better known as "managed DNS" services) DynDNS, TZO, No-IP, and DotQuad, as well as Google and Comcast. more

Malware and Search Warrant

A recent decision from a federal district court addresses an issue I hadn't seen before: whether searching malware on the suspect's computer was outside the scope of the search warrant issued for that computer. It seems a narrow issue, and unfortunately the opinion issued in the case doesn't tell us a whole lot about what happened; but I thought the issue was worth writing about, if only to note that it arose. more

More Stepping Stones Before This Summer’s Seminal DNSSEC Events

The deployment of Domain Security Extensions (DNSSEC) has crossed another milestone this month with the publication of DURZ (deliberately unvalidatable root zone) in all DNS root servers on 5 May 2010. While this change was virtually invisible to most Internet users, this event and the remaining testing that will occur over these next two months will dictate the ultimate success of DNSSEC deployment across the Internet. more
