DNSSEC

IP-based networks, including the Internet, route information between computers based on their IP address (such as 208.77.188.166). Directly using these numbers would cause many problems, so Domain Name System (DNS) is a critical service of such networks. DNS accepts a domain name (such as www.example.com) and responds with information about that name, such as its matching IP address. DNS can also perform reverse look-ups (given an IP address, return the corresponding name). Unfortunately, DNS was not designed to be secure. DNSSEC was designed to protect Internet resolvers (clients) from forged DNS data. It is widely believed that deploying DNSSEC is critically important for securing the Internet as a whole, but deployment has been hampered by some difficulties. Some of these problems are in the process of being resolved, and deployments in various domains have begun to take place. Read the full background at DNSSEC Wikipedia

Is This Only Sloppy Wording by ICANN?

So I wrote earlier that I though it was good stuff when ICANN released a paper on DNS Security. Yes, I think it was good this paper was released, and yes it points out correctly how important DNSSEC is. But, now when reading it in detail, I find two things that troubles me. And it has to do with management of .ARPA. A top level domain that is used for infrastructural purposes. Like IP-addresses and E.164 numbers... more»

ICANN Releases Paper on Domain Name Security

Today ICANN releases a paper with the title "DNSSEC @ ICANN - Signing the root zone: A way forward toward operational readiness". The paper explains in more detail than earlier documents what ICANN view on signing of the root zone is. I think the key points mentioned in this paper are true, and in general, I think this document is a good read. It is not long, and summarizes what I would call the current view is. more»

An Astonishing Collaboration

Wow. It's out. It's finally, finally out... So there's a bug in DNS, the name-to-address mapping system at the core of most Internet services. DNS goes bad, every website goes bad, and every email goes...somewhere. Not where it was supposed to... I'm pretty proud of what we accomplished here. We got Windows. We got Cisco IOS. We got Nominum. We got BIND 9, and when we couldn't get BIND 8, we got Yahoo, the biggest BIND 8 deployment we knew of, to publicly commit to abandoning it entirely. It was a good day... more»

Will a Global TAR Make DNSSEC Stick?

Two US Government contractors and the National Institute of Science and Technology have released a white paper, "Statement of Needed Internet Capability," detailing possible alternatives and considerations for a Trust Anchor Repository (TAR) to support DNSSEC deployment. The document was released through the DNSSEC-Deployment Group this week with a request that it be circulated as widely as possible to gather feedback. A Trust Anchor Repository (TAR) refers to the concept of a DNS resource record store that contains secure entry point keys... more»

DNSSEC Adds Value?

The recent news that .uk, .arpa and .org may sign their zones sometime this year is indeed good news. Each domain is highly significant... As the DNSSEC registry infrastructure moves inexorably forward -- primarily driven by top level pressure and considerations of National Interest -- it now behoves us to clearly articulate the benefits of DNSSEC to domain owners and registrars. In particular I want to focus on the vast majority of us to whom cold, hard cash is important and parting with it requires as a minimum tangible benefits or, in extreme cases, surgical intervention. more»

Domain Name Price Jump: Moore's Law or Parkinson's Laws?

As expected, VeriSign raised the price of domain names, effective in October. New prices wholesale prices (to the registrar) for .com domain names are going from $6.42 to $6.86, while .net will increase from $3.85 to $4.23. This news came a few days ago in a letter to registrars. (Hint to consumers: renew your domains now.) ...So, basically, many if not most of VeriSign's registry costs have been falling at an exponential rate. Hard disk storage, computing performance, bandwidth, RAM storage... yet the cost is going up. How is this justified? more»

Domain Pulse 2008: Day 2 Focuses on DNS Security

Day two of Domain Pulse 2008 last Friday (see review of day one) focused on online security issues giving the techies amongst us details of security issues, and the more policy-orientated amongst us something to chew on in a few other presentations. Kieren McCarthy, these days of ICANN, also gave some insights into the drawn out sex.com drama with more twists and turns than the average soap opera has in a year! And Randy Bush outlined the problems with IPv6. Among other presentations... more»

Homeland Security Department Was Warned About DNSSEC Key Ownership and Trust Issues

The Internet Governance Project has unearthed a consultancy report to the U.S. Department of Homeland Security (DHS) that makes it clear that the issue of root signing and DNSSEC key management has been recognized as a political issue within the US government for long time. more»

DNSSEC: Once More, With Feeling!

After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. more»

Developing Internet Standards: How Can the Engineering Community and the Users Meet?

There is currently a discussion going on between Milton Mueller and Patrik Fältström over the deployment of DNSSEC on the root servers. I think the discussion exemplifies the difficult relation between those who develop standards and those who use them. On the one hand, Milton points out that the way the signing of the root zone will be done will have a great influence on the subjective trust people and nation states will have towards the system. On the other hand, Patrik states that "DNSSEC is just digital signatures on records in this database". Both are right, of course, but they do not speak the same language... more»

.ORG Applauds US Government on DNSSEC

.ORG applauds the US Government's decision last week to require all users of the .GOV domain to implement DNSSEC, and even more importantly, to sign the .GOV root. .ORG is the first generic Top Level Domain authorized by ICANN to implement DNSSEC, and we are hard at work putting together a comprehensive plan to roll it out. ›››

On the Pressing Need for a Signed Root

Attacks on the security of the Internet have been much in the news lately, and there is an increased urgency to take the technical steps to combat these attacks. .ORG has been doing its part to lead this process by taking introductory steps to implement DNSSEC (Domain Name System Security Extensions)... In order to make DNSSEC effective, there is one additional step that is needed -- "signing the root". ›››

.ORG Becomes the First Generic Top level Domain to Start DNSSEC Implementation

A request by .ORG, The Public Interest Registry to bolster Internet security via the implementation of Domain Name Security Extensions (DNSSEC) was unanimously approved by ICANN at the recent Paris meeting. As the first generic Top Level Domain authorized to implement DNSSEC, .ORG also is preparing an education and adoption plan within the Internet infrastructure community. ›››
