DNSSEC Adoption Part 3: A Five Day Hole in Online Security

Implementing security requires attention to detail. Integrating security services with applications where neither the security service nor the application consider their counterpart in their design sometimes make plain that a fundamental change in existing practices is needed. Existing "standard" registrar business practices require revision before the benefits of the secure infrastructure foundation DNSSEC offers can be realized. more»

The Resolvers We Use

The Internet's Domain Name System is a modern day miracle. It may not represent the largest database that has ever been built, but nevertheless it's truly massive. And even if it's not the largest database that's ever been built, it's perhaps one of the more intensively used... Given the fragmentation of the IPv4 address space with the widespread use of various forms of address sharing, then it increasingly looks as if the DNS is the only remaining common glue that binds the Internet together as a single network. more»

DNSSEC Adoption Part 2: The Current Functionality Gap

Registrars have the opportunity to fundamentally change the landscape of the Internet's security infrastructure by working to close the DNSSEC functionality gap. Virtually everything every Internet user does on the Internet depends on the DNS. DNSSEC is not just about protecting the DNS, it is about building a secure infrastructure foundation upon which new and innovative services and applications can be built to benefit us all. Registrars are the linchpins to advancing the deployment of DNSSEC. more»

DNSSEC Workshop Streaming Live From ICANN 51 On Wednesday, Oct 15

Want to learn about the state of DNSSEC usage in North America? Or what is new in DNS monitoring? Or where DNSSEC fits into the plans of operating systems? Or how DANE is being used to bring a higher level of security to email? All those questions and much more will be discussed at the DNSSEC Workshop at ICANN 51 happening on Wednesday, October 15, 2014, from 8:30 am to 2:45 pm Pacific Daylight Time (PDT, which is UTC-7). more»

Some Observations from NANOG 62

NANOG 62 was held at Baltimore from the 6th to the 9th October. These are my observations on some of the presentations that occurred at this meeting. .. One of the more memorable sides in this presentation was a reference to "map" drawn by Charles Minard in 1869 describing the statistics relating to the Napoleonic military campaign in Russia, and the subsequent retreat. more»

Credit Card Breaches a Salutary Lesson for DNSSEC Adoption

Maintaining an 150 year old house requires two things, a lot of time and a lot of trips to the hardware store. Since the closest hardware store to my house is Home Depot, it is rare that a weekend passes without at least one trip to Home Depot. So now in the wake of the Home Depot data breach I am through no fault of my own in a situation where any or all of the bank cards I use regularly could be cancelled if the issuer decides they might be compromised. And this is not the first time this has happened to me this year. more»

Some Internet Measurements

At APNIC Labs we've been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP. The intent of this particular set of data collections is to allow the data to be placed into a relative context, displaying comparison of the individual measurements at a level of geographic regions, individual countries, and individual networks. more»

A Great Bit of DNSSEC and DNS at IETF 90 Next Week

For those people tracking the evolution and deployment of DNSSEC or who are just interested in "DNS security" in general there is a great amount of activity happening next week at IETF 90 in Toronto. I dove into this activity in great detail in a recent post, "Rough Guide to IETF 90: DNSSEC, DANE and DNS Security", and summarized the activity in a Deploy360 post... more»

Now Available - A Trend Chart Tracking DNSSEC Validation Globally

How can we track the amount of DNSSEC validation happening globally? Is there a way we can see the trend over time to (we hope!) see validation rise? At the recent excellent DNSSEC Workshop at ICANN 50 in London Geoff Huston let me know that his APNIC Labs team has now created this exact type of trend chart. more»

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more»
