There's been a lot of emphasis on DNS performance lately because faster DNS contributes directly to a better user experience. There's an interesting flipside to DNS performance though, higher performance DNS servers may be better targets for cache poisoning attacks. Faster servers give attackers more opportunities to insert fake entries into the DNS - speed can kill (or at least inflict a nasty wound!) so it's important to understand the security implications if you're looking to upgrade DNS performance. more
I'm sitting in the Popov Room of the ITU Tower in Geneva, the room is quiet, the atmosphere placid, chairs are empty. The final meeting of the CWG WCIT prep WG has just concluded its work and the chair will be reporting to the Council the results of our work. I find myself strangely calm and looking forward to my next week, to be spent in Prague... Should you choose to read through the documents, and they are lengthy at approximately 375 pages, you might think that a number of the proposals were directed at the Internet. more
Just in time for ICANN's 44th meeting next week, a new Internet Draft has turned up, purporting to fix the centralization of the DNS. The draft has received some attention, including an article in PC World. It isn't entirely clear what the real purpose of the draft is, but it is hard to credit the notion that it is solving any technical problem. Without examining the reasons why the draft exists, I want to debunk a claim in it. more
ICANN's 44th public meeting is about to start in a few days with a number of topics on the agenda. Some of them are new, while some of them are ongoing. First off, ICANN will be announcing the new CEO this Friday afternoon in Prague. Whoever it is will be coming to the organisation at a time when it faces a number of significant challenges. While the actual official meeting does not start until Monday morning there will be plenty of meetings on over the weekend as well... So what's on the "menu" for Prague? more
At the press conference held in London on June 13, the Internet Corporation for Assigned Names and Numbers (ICANN) officially announced a list of 1930 applications for the new generic top level domain (gTLD). During the 40 years since the launch of the Internet, there are only 22 gTLDs such as .com. The 1930 applications represent a historical change to the Internet; For the first time, Chinese gTLDs will become available and there are 67 unique applications for Chinese gTLDs. more
As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. more
A woman on the radio talks about revolution, though it's already passed. The window is now closed. A snapshot can be taken. A baseline can be set. How have the public markets valued the new gTLD program? And more importantly, how will public markets value it going forward? Until a few months ago, the new gTLD program was arcane policy discussion among a very narrow technical population of the Internet community. more
Google has announced that it has started undertaking an effort to notify roughly half a million people whose computers or home routers are infected with a well-publicized form of malware known as DNSChanger. "After successfully alerting a million users last summer to a different type of malware, we've replicated this method and have started showing warnings via a special message that will appear at the top of the Google search results page for users with affected devices." more
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. more
A recent report by Pingdom looks at the booming growth of Internet's DNS infrastructure. From the article: "Five years ago there were 123 DNS root server sites (the "backend" of DNS) spread out on the Internet. Today there are more than twice as many, over 300. Five years ago, 46 countries had root servers. Today, 76 have them. In other words, not only has the number of root servers grown tremendously, but their geographical spread has increased as well. This is good news for the overall stability and performance of DNS worldwide." more
There has been a lot of talk about how the DNS can provide network-based security, and how DNS is in the best position to detect malware traffic before it does any harm. But what does this mean for end users? How does it make their online lives easier and more secure? DNS servers that are aware of sites that host malware, perform phishing activities (harvesting bank details, for instance) and other nefarious misbehaviors, can prevent end users from ever going to those sites. more
The sixth annual Counter-eCrime Operations Summit (CeCOS VI) will engage questions of operational challenges and the development of common resources for the first responders and forensic professionals who protect consumers and enterprises from the ecrime threat every day. This year's meeting will focus on the shifting nature of cybercrime and the attendant challenges of managing that dynamic threatscape. more
Internet Society recently announced the appointment of former chief technology officer of Motion Picture Association of America (MPAA). The decision has raised concerns within the Internet community as Paul Brigner had campaigned for SOPA while at MPAA as well as being on record opposing net neutrality while being an official at Verizon. more
As regular readers know, ICANN holds lengthy, in-depth discussions devoted to DNSSEC at each of its three annual meetings. The half-day session held at ICANN 43 in Costa Rica last month was particularly interesting. What became clear is that the industry is quickly moving into the end-user adoption phase of global DNSSEC deployment. more
There was a period of time not long ago in which signature-based threat detection was cutting-edge. Antivirus, intrusion detection systems (IDS), data leakage prevention (DLP), content filtering and even anomaly detection systems (ADS) all continue to rely heavily upon static signatures. In recent years vendors have shied away from discussing their dependence on such signatures -- instead extolling supplemental "non-signature-based" detection technologies. more
