Persistent Threat Detection on a Budget

If there's one simple - high impact - thing you could do to quickly check whether your network has been taken over by a criminal entity, or uncover whether some nefarious character is rummaging through your organizations most sensitive intellectual property out of business hours, what would it be? In a nutshell, I'd look to my DNS logs. It's staggering to me how few security teams have gotten wise to regularly interrogating the logs from their recursive DNS servers. more

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more

Names, Numbers and Beyond…

Couple of weeks ago I started a new initiative called "Names, Numbers and Beyond". I started this as I genuinely think we are facing big issues due to the uncontrolled and non-standard growth of the IP and Name space used today and tomorrow. To keep in control and make everything manageable, parcelling out IP address space and the use of tight naming standards/policies is necessary to make networks work better and make them achievable. more

FBI Agent Thomas X. Grasso Receives First J.D. Falk Award for Establishing DNS Changer Working Group

Convincing competitors, disparate business entities and researchers to collaborate - many donating their services and resources - to protect millions of end-users worldwide is no small feat. Yet FBI Supervisory Special Agent Thomas X. Grasso did just that by quietly working behind the scenes to create the DNS Changer Working Group that saved an inestimable number of end-users from losing access to the Web over the last two years. more

A Perspective on Verisign’s Patent Application on Domain Name Transfers

As the battle rages over threats to the Internet architecture, a recent publication over the Patent Application for Domain Name Transfers by Verisign is disturbing for those who advocate an open and free Internet. The Application is based on an immediate and direct threat towards an open and free Internet. Just in case people are tempted to think that this was a prank given that they filed it on the 1 April 2011, searches at the United States Patents and Trademark Office (USPTO) reveals that this is a legitimate application . more

Twitter’s t.co Domain Outage Caused by Human Error

Declan McCullagh reporting in CNET: "Twitter last year began to abbreviate all hyperlinks using its t.co domain name -- which had the side effect of introducing a central point of failure where none existed before. That failure happened last night [Sunday Oct 7] around 11:30 p.m. PT when t.co went offline, meaning millions of Twitter users received 'non-existent domain' errors when trying to follow links." more

Internet Society ION Conferences: Call for Speakers - IPv6 and DNSSEC Experts

The Internet Society Deploy360 Programme issues a call for speakers for a series of upcoming global ION Conferences. ISOC welcomes submissions from IPv6 and DNSSEC experts to speak at any of the following ION conferences. more

Nitol and 3322.org Takedown by Microsoft

Reading this morning's blog from Microsoft about "Operation b70" left me wondering a lot of things. Most analysts within the botnet field are more than familiar with 3322.org - a free dynamic DNS provider based in China known to be unresponsive to abuse notifications and a popular home to domain names used extensively for malicious purposes - and its links to several botnets around the world. more

The outage lasted for about four hours and affected mainly small-business sites. GoDaddy.com hosts more than 5 million websites. more

Researchers Detail Faster Methods to Defeat Botnets Like Conficker and Kraken

Michael Cooney reporting in NetworkWorld: "Security researchers this week will detail a prototype system they say can better detect so-called Domain Name Generation- (DGA) based botnets such as Conficker and Kraken without the usual labor- and time-intensive reverse-engineering required to find and defeat such malware. The detection system, called Pleiades, monitors traffic below the local DNS server and analyzes streams of unsuccessful DNS resolutions..." more

New Top Level Domains Application Metering - Figure It Out ICANN!

Let me begin by saying that I am big supporter of ICANN. But good grief ICANN, why must the ENTIRE new gTLD process be so painful? I could run through a long list of all the delays, missteps and glitches, but why bother? It's almost comical at this point -- although not for 1,930 new gTLD applicants who have been waiting for ICANN to get their act together. First we were led to believe that the batching of applications was necessary due to resourcing constraints, which I personally never understood as the evaluation of applications is being done be third-party consultants. more

How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more

“Globally, Internet Traffic Passes Through 13 Root Servers” (!)

The Times of India recently interviewed India's Minister of State for Communications and IT, Sachin Pilot, on Internet Governance. Titled "'Internet's governance can't be limited to one geography'", the article started off with an amazing assertion by the minister... While this interview is a fairly standard restatement of the position some Governments (including India) have about governmental control of Internet Governance, it is sadly apparent that the minister unfortunately doesn't appear to understand what the root servers are, or how they work. more
