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.

IP Addresses and Privacy Sensitive Data - A Level Playing Field Needed

Reading Peter Olthoorn's book on Google (a link is found here), I ran into a passage on IP addresses. Where Google states that it does not see an IP address as privacy sensitive. An IP address could be used by more than one person, it claims. The Article 29 Working Party, the EU privacy commissioners, states that it is privacy sensitive as a unique identifier of a private person. It got me wondering whether it is this simple. Here is a blog post meant to give some food for thought and debate. I invite you to think about the question 'how private is an IP address'?

A Logical Place to Start the IPv6 Transition

The transition to IPv6 is top of mind for most service providers. Even in places where there are still IPv4 addresses to be had surveys we've run suggest v6 is solidly on the priority list. That's not to say everyone has the same strategy. Depending where you are in the world transition options are different -- in places such as APAC where exhaustion is at hand one of the many NAT alternatives will likely be deployed since getting a significant allocation of addresses is not going to happen and other alternatives for obtaining addresses will prove expensive.

Hosters: Is Your Platform Being Used to Launch DDoS Attacks?

As anyone who's been in the DDoS attack trenches knows, large multi-gigabit attacks have become more prevalent over the last few years. For many organizations, it's become economically unfeasible to provision enough bandwidth to combat this threat. How are attackers themselves sourcing so much bandwidth?

End of the World/Internet on 31-March-2012?

Well... Maybe not the world, but the Internet it seems. According to a Pastebin letter, Anonymous announced they will black-out Internet on 31st of March. They even explained how to do it by attacking the DNS Root Servers on Internet using a reflected amplification attack. If this is successful, the root DNS servers will become unresponsive and cannot handle any other requests...

Cloud Computing’s Concealed Complexity

James Urquhart claims Cloud is complex - deal with it, adding that "If you are looking to cloud computing to simplify your IT environment, I'm afraid I have bad news for you" and citing his earlier CNET post drawing analogies to a recent flash crash. Cloud computing systems are complex, in the same way that nuclear power stations are complex - they also have catastrophic failure modes...

2011 Domain Name Year In Review: Top 10 Biggest Domain Stories

Who would have ever believed that .XXX would finally be approved AND launched, total domains registrations would continue to grow at 10% year over year, ICANN would be in the process of preparing for the launch of new gTLDs in the face of harsh criticism, and that both Go Daddy and Group NBT would be acquired by private equity firms. As we look back over the past year, here are the top 10 biggest domain stories of 2011.

DDoS Mitigation: A Blend of Art and Science

As DDoS attacks become larger, more frequent and complex, being able to stop them is a must. While doing this is part science, a matter of deploying technology, there is also an art to repelling sophisticated attacks. Arbor Networks, Citrix and others make great gear, but there's no magic box that will solve all your problems for you. Human expertise will always be a crucial ingredient.

2012 Security Predictions: APT’s, Mobile Malware and Botnet Takedowns

As the weeks remaining in 2011 dwindle and 2012 peaks out from behind the last page of the calendar, it must once again be that time of year for purposeful reflection and prediction. Or is that navel gazing and star gazing? At the highest level of navel gazing you could probably sum up 2011 with one word -- "More"... But let's put that aside for now. What does 2012 hold in stall for us?

What Chinese DDoS Malware Looks Like

While at that same Virus Bulletin conference that I was talking about earlier in my other post, I also had the chance to check out a session on Chinese DDoS malware put on by some folks from Arbor Networks. As little insight as I have into Android malware, I know even less about Chinese DDoS malware. So what's Chinese DDoS malware like? What are its characteristics?
