Many organizations today are tightening their belts. They have smaller budgets and fewer resources even though they face an ever-growing list of projects, tasks and corporate IT initiatives to complete. IT departments are hard pressed to streamline operations but don't necessarily have the manpower -- be it resources or specific skillsets -- to add capabilities that will achieve such efficiency. There are only a few possible solutions organizations can consider to address this common problem... more
In the past 24 months, distributed denial of service (DDoS) attacks have changed profoundly. Gone are the days when attackers worked under the radar, when machines were infected by botnet code unknowingly and attacks were disguised leaving very little to trace the exact origin. ... The other game-changer: It's easier than ever to execute attacks. The tools are so widely available that anyone with basic skills and a high-speed connection can become a "hacktivist." more
The Internet Society (ISOC) has addressed human rights issues related to Internet access stating "[t]he increasing pressure to limit access to the Internet has escalated the sense of urgency in addressing this situation." ISOC, in the announcement, reaffirmed its policy area and its work to bring attention to the impact of Internet freedom on other aspects of human rights. more
As the countdown for the ICANN gTLD program ticks away its final 100 days, potential dot Brand applicants have to make important decisions in a short space of time: whether to apply for a new TLD, how to best leverage a new top-level domain, and which gTLD partner to choose. Most dot Brand applicants have excellent IT departments, but these resources are already over-stretched with current projects, and they likely lack the specific skills and experience needed to meet ICANN's exacting standards in the highly specialized area of top-level domain registry technology. more
One of the primary purposes of the ICANN New generic Top-Level Domain (gTLD) program is to foster innovation in the DNS industry and the wider Internet. While having a desirable TLD string that users can relate to is a good starting point, gTLD applicants may want to bolster their value propositions by offering innovative services and differentiate their TLDs from others. Defining the services to be offered is so central to a gTLD that it should be part of the initial strategy of any prospective applicant. more
According to Kaspersky Lab, 2011 has seen "numerous DDoS attacks with a variety of motives," many of which will "go down in the annals of cybercrime." As we look ahead to 2012, it's worth examining some of those motives to see what they portend. more
While it would be nice if your company had IT staff members that were experts in every technology, that is just not realistic. And today, many companies face the challenge of finding the appropriate and specialized expertise that is required to deal with ongoing issues such as network optimization, performance degradations, network risks, and more. more
Signing Email is now a Draft Standard! Signing email transitioned from a proposed standard to a draft standard (RFC6376 -- one of the new RFCs) over at the IETF a few days ago. The other is RFC6377. Let's go through a brief history of DKIM RFCs to refresh our memories... more
ICANN has launched a micro-site to serve as the online source for New Generic Top-Level Domain (New gTLDs) Program. From ICANN's announcement: "ICANN is in the midst of a major campaign to raise awareness around the world about the impact and possibilities of new gTLDs. The new site represents a foundational expression of the campaign. Many more new articles, tools, and materials will be made available in the coming days and weeks." more
The Domain Name System, or DNS, has come a long way since its early days and the constant expansion of consumer activity and security concerns has raised further awareness about the critical role of the DNS. However, as the Yankee Group Research points out in a recent report, "there are more changes coming that are also raising the profile of DNS -- notably the move to cloud computing and the migration to IPv6." Suffice to say this is "Not Your Father's DNS". The report titled, "DNS: Risk, Reward and Managed Services" takes a fresh look at today's state of the DNS and the pros and cons of in-house, ISP and managed service provider DNS management options. more
When it comes to building a robust globe-spanning network of crimeware and making the victims dance to a tune of the cyber-criminals' choosing, you're guaranteed to find domain name abuse at the heart of the operation. DNS provides the critical flexibility and underlying scalability of modern command-and-control (C&C) infrastructure. Cyber-criminals that master DNS (and manage to maintain the stream of new domain registrations that keep it fed) tend to find themselves in command of the largest and most profitable crimeware networks. more
In previous installments we've been looking at aspects of the design of the DNS. Today we look at the relationship of similar names in the DNS. A poorly appreciated aspect of the DNS is that there is no inherent relationship between similar looking names. more
In the five previous exciting installments, we've been looking at aspects of the design of the DNS. Today we look at records types, and how you can tell what a DNS record means. All the records in the DNS are strongly typed. Each record includes an RRTYPE, a small number, which defines both the format of the record and what the record means. It is possible and common to have different record types with the same format, but different meanings. more
In the previous four installments, we've been looking at aspects of the design of the DNS. Today we look at the amount of data one can ask the DNS to store and to serve to clients. Most DNS queries are made via UDP, a single packet for query and a single packet for the response, with the packet size traditionally limited to 512 bytes. This limits the payload of the returned records in a response packet to about 400 bytes... more
The latest Domain Name Industry Brief published by Verisign reports more than 5 million domain names were added to the Internet in the second quarter of 2011, bringing the total number of registered domain names to more than 215 million worldwide across all domains. The increase of 5.2 million domain names marks a growth rate of 2.5 percent over the first quarter. Registrations have grown by more than 16.9 million, or 8.6 percent, since the second quarter of 2010. more
