The 46th meeting of the Internet Corporation for Assigned Names and Numbers (ICANN) takes place this week in Beijing, China, and will bring together leaders from all over the world to discuss and debate a wide range of issues related to domain names and the surrounding industry. One can expect that the new gTLDs, a topic frequently discussed here on CircleID, will naturally consume a great amount of the discussion at ICANN 46. more
There has been plenty of buzz and chatter on the Internet recently concerning a very large DDoS attack against CloudFlare, with coverage on their blog, the New York Times, and the BBC, among many others. While attacks of this nature are certainly nothing new, the scale of this attack was surprising, reported to hit 120Gbps. For a sense of scale, your average cable modem is only about 20Mbps, or about 0.016% of that bandwidth. more
Neil Schwartzman writes to report that U.S. Cert issued Alert TA13-088A on Friday March 29, 2013. "It is a solid how-to guide to test for, and remediate DNS configurations that can be used for Distributed Denial of Service attacks." more
For those of you interested in IPv6 and/or DNSSEC, we'll have a live webcast out of the Internet Society's ION Singapore conference happening tomorrow, March 28, 2013, starting at 2:00pm Singapore time. more
Google today announced that its "Public DNS" service is now performing DNSSEC validation. Yunhong Gu, Team Lead for Google Public DNS, in post today wrote: "We launched Google Public DNS three years ago to help make the Internet faster and more secure.Today, we are taking a major step towards this security goal: we now fully support DNSSEC (Domain Name System Security Extensions) validation on our Google Public DNS resolvers." more
ICANN has released a set of guidelines to explain its Coordinated Vulnerability Disclosure Reporting. The guidelines serve two purposes, says ICANN: "They define the role ICANN will perform in circumstances where vulnerabilities are reported and ICANN determines that the security, stability or resiliency of the DNS is exploited or threatened. The guidelines also explain how a party, described as a reporter, should disclose information on a vulnerability discovered in a system or network operated by ICANN." more
I co-authored a book in 2005, titled "Extreme Exploits: Advanced Defenses Against Hardcore Hacks." My chapters focused on securing routing protocols such as BGP, and securing systems related to DMZs, firewalls, and network connectivity. As I look back over those chapters, I realize that the basic fundamentals of network security really haven't changed much even though technology has advanced at an incredible pace. "Defense in depth" was a hot catch phrase seven years ago, and it still applies today. more
Consumption of software as a service with a usage-based business model has gained incredible popularity in recent years. On the other hand, other cloud services such as infrastructure and platform as a service are just starting to pick up. While compute and storage are by the far the most commonly used cloud infrastructure services, few consider core network services such as IP Address Management (IPAM) as something that could be utilized over the cloud. more
In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more
I could have ignored yesterday's ICANN New gTLD Applicant Update Webinar and just read summaries from the usual respected news and industry sources. However, with three hours slotted and likely questions regarding ICANN CEO Fadi Chehadé's somewhat eyebrow-raising comments at the regional ICANN Registry-Registrar meeting in Amsterdam last week -- led me wanting to hear it all myself. more
In part 1, I talked about some of the risks associated with BYOD. But there are actions you can take to greatly reduce this risk. One effective method for limiting the risk of BYOD is to employ DNS-based security intelligence techniques. DNS-based security intelligence makes use of an enterprise's caching DNS server to monitor and block DNS queries to known botnet command and control (C&C) domains. more
In my previous post, I talked about the significance of DNS in connection with the Software Defined Data Center (SDDC) and Software Defined Networking. Although the second generation DNS provisioning model I outlined should have seemed straight-forward enough, in real life it is anything but. In my view, the real-world complications of a seemingly trivial issue are largely related to how the network industry approaches IP addressing. more
The number of 'things' connected to the internet is already bypassing the number of people on the planet. This Internet of 'things' is changing the way we live and work: from the way food is grown and produced on farms through automated temperature and feeding controls, to the way we check prices and buy through connected terminals, to the vehicles we drive, the security cameras at work, and automated gates at the entrance. Connected 'things' are everywhere. All these 'things' are helping us to be more productive and efficient while also offering more and more convenience. more
During 2012, Software Defined Networking (SDN) seemed to be all the rage. The VMware acquisition of Nicira during the summer doldrums for US $1.26 billion validated the fact that the SDN paradigm is expected to have some serious legs over the coming years. I guess the same applies to virtualized network services in general, although the acquisitions in that space were not quite as high-profile as the ones in SDN. more
