A recent progress report on DNSSEC adoption reveals the extent to which organizations in a number of industries are falling short of their own objectives for making Domain Name Server (DNS) infrastructure more secure. The progress report, conducted by Secure64 Software Corporation, is a follow-up to a 2010 study by Forrester Research titled, "DNSSEC Ready for Prime Time," which reported on organizations' plans to implement DNSSEC in order to shore up vulnerabilities in DNS. more
It has been about six months since I got together with four of my friends from the DNS world and we co-authored a white paper which explains the technical problems with mandated DNS filtering. The legislation we were responding to was S. 968, also called the PROTECT-IP act, which was introduced this year in the U. S. Senate. By all accounts we can expect a similar U. S. House of Representatives bill soon, so we've written a letter to both the House and Senate, renewing and updating our concerns. more
"The General Services Administration is analyzing what caused an outage of .gov websites for a few hours Wednesday morning," reports Federal Times. Officials said the problem involved so-called DNSSEC cybersecurity measures that affected access to certain .gov sites, according to GSA spokeswoman Mafara Hobson. more
There has been a lot of criticism about the worthiness of DNSSEC. Low adoption rates and resistance and reluctance by Registrars to take on the perceived burden of signing domains and passing-on cryptographic material are at the crux of the criticism. I'm a believer in DNSSEC as a unique and worthwhile security protocol and as a new platform for innovation. It's the reason I've long advocated for and continue to work toward a new model of DNSSEC provisioning. more
Internet Society's DNSSEC Deployment Maps are now available as part of a larger set of Global Internet Maps from its annual Global Internet Report. The map is based off of the 5 stages of DNSSEC deployment that the organization tracks as part of the weekly DNSSEC deployment maps generated. more
The deployment of Domain Security Extensions (DNSSEC) has crossed another milestone this month with the publication of DURZ (deliberately unvalidatable root zone) in all DNS root servers on 5 May 2010. While this change was virtually invisible to most Internet users, this event and the remaining testing that will occur over these next two months will dictate the ultimate success of DNSSEC deployment across the Internet. more
One of the "key" questions cryptographers have been asking for the past decade or more is what to do about the potential future development of a large-scale quantum computer. If theory holds, a quantum computer could break established public-key algorithms including RSA and elliptic curve cryptography (ECC), building on Peter Shor's groundbreaking result from 1994. more
The canonical specification of the DNS that is normally cited are the pair of quite venerable RFCs, RFC 1034, "Domain names - concepts and facilities", and RFC 1035, "Domain names - implementation and specification", both published in November 1987. However, these two specification documents are just the tip of a rather large iceberg. One compendium of all the RFCs that touch upon the DNS lists some 292 RFCs. 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
At ICANN's meeting in Egypt last week, I had the opportunity to try and explain to various non-technical audiences why the Domain Name System (DNS) is vulnerable to attack, and why that is important, without needing a computer science degree to understand it. Here is the summary. more
In January we presented the glorious history of the MIT spam conference, today we present the schedule for the first day. Opening session will be from this author, Garth Buren with a topic entitled The Internet Doomsday Book, with details be released the same day as the presentation. Followed by Dr. Robert Bruen with a review of activities since the last MIT spam conference... more
Despite security advances over the past year, including the increased deployment of DNSSEC, pirates continue to wreak havoc on the Internet. But before you decide that Internet security innovations are futile, consider this: online criminals are just like burglars in the physical world; they don't take new ways of blocking their best efforts lying down. They come up with new and, in some cases, stronger plans of attack. more
In my last article, I described efforts underway to standardize new cryptographic algorithms that are designed to be less vulnerable to potential future advances in quantum computing. I also reviewed operational challenges to be considered when adding new algorithms to the DNS Security Extensions (DNSSEC). In this post, I'll look at hash-based signatures, a family of post-quantum algorithms that could be a good match for DNSSEC from the perspective of infrastructure stability. more
The Internet is slowly beginning to adopt the new DNSSEC domain names standard, but significant challenges remain. That was the main takeaway from a four-hour workshop on the technology held during the recent ICANN 41 public meeting in Singapore, which heard from many domain registries, registrars and other infrastructure providers. more
