Preventing DNS Strain When You Deploy DNSSEC

The barriers to DNSSEC adoption are quickly disappearing. There are nearly 20 top-level domains that have already deployed DNSSEC including generic TLDs like .org and .gov. This July, the DNS root will also be signed, and will begin validating. At this point, the decision for remaining TLDs to deploy DNSSEC is really no longer a question. more

Cryptographic Tools for Non-Existence in the Domain Name System: NSEC and NSEC3

In my previous post, I described the first broad scale deployment of cryptography in the DNS, known as the Domain Name System Security Extensions (DNSSEC). I described how a name server can enable a requester to validate the correctness of a "positive" response to a query -- when a queried domain name exists -- by adding a digital signature to the DNS response returned. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 2)

This post follows an earlier post about DNS amplification attacks being observed around the world. DNS Amplification Attacks are occurring regularly and even though they aren't generating headlines targets have to deal with floods of traffic and ISP infrastructure is needlessly stressed -- load balancers fail, network links get saturated, and servers get overloaded. And far more intense attacks can be launched at any time. more

Call For Participation - ICANN 52 DNSSEC Workshop on 11 Feb 2015 In Singapore

If you will be at ICANN 52 in Singapore in February 2015 (or can get there) and work with DNSSEC or the DANE protocol, we are seeking proposals for talks to be featured as part of the 6-hour DNSSEC Workshop on Wednesday, February 11, 2015. The deadline to submit proposals is Wednesday, December 10, 2015... The full Call For Participation is published online and gives many examples of the kinds of talks we'd like to include. more

Join Live On Sunday - 2nd Registration Operations Workshop (ROW) In Dallas

This Sunday, March 22, 2015, the second Registration Operations Workshop (ROW) will be taking place at the Fairmont Dallas hotel from 12:30 -- 4:30 pm CDT. Discussion will include extensions to EPP, new encryption initiatives and also suggestions for ways to further automate DNS interactions between registries, registrars and DNS operators, including a need to do this for DNSSEC. more

Proposal for Signing the DNSSEC Root

The U.S. National Telecommunications and Information Administration (NTIA) is soliciting comments on signing the DNSSEC root. Ignore the caption on the page: this is not about DNSSEC deployment, which is already happening just fine. It's about who gets to sign the root zone. more

Ongoing Community Work to Mitigate Domain Name System Security Threats

For over a decade, the Internet Corporation for Assigned Names and Numbers (ICANN) and its multi-stakeholder community have engaged in an extended dialogue on the topic of DNS abuse, and the need to define, measure and mitigate DNS-related security threats. With increasing global reliance on the internet and DNS for communication, connectivity and commerce, the members of this community have important parts to play in identifying, reporting and mitigating illegal or harmful behavior, within their respective roles and capabilities. more

Why DNS Is Broken, Part 2: DoS Target

Before we get into what DNSSEC is and the benefits of it, let's talk about some of the other potential pitfalls of DNS. One of the most significant issues we have to deal with are denial-of-service (DoS) attacks. While DoS attacks are not specific to DNS we have seen DNS be a frequent target of these attacks. more

Global DNS Record Manipulation, Hijacking Campaign at Massive Scale Linked to Iran

A wave of DNS hijacking is reported to have affected dozens of domains belonging to government, telecommunications and internet infrastructure entities across the Middle East and North Africa, Europe and North America. more

The Path Toward Increasing the Security of DNSSEC with Elliptic Curve Cryptography

How do we make DNSSEC even more secure through the use of elliptic curve cryptography? What are the advantages of algorithms based on elliptic curves? And what steps need to happen to make this a reality? What challenges lie in the way? Over the past few months we've been discussing these questions within the community of people implementing DNSSEC, with an aim of increasing both the security and performance of DNSSEC. more

ISC Assesses DNS Flag Day

Everyone who participated in supporting DNS Flag Day initiative should feel they have accomplished something worth-while, says ISC's Vicky Risk. more

The Christmas Goat and IPv6 (Year 3)

As Christmas were getting closer, the third time of load balancing the streaming pictures of the famous Christmas goat in the city of Gävle, Sweden, was on the agenda. My goal with this activity is the same as before, to track the use of IPv6 and DNSSEC validation. The results from the last two years are published on CircleID. more

Why Are Internet Security Standards Badly Deployed and What to Do About It?

In 2019 under the aegis of the Internet Governance Forum, a pilot project was conducted into the causes of and solutions for the, in general, slow deployment of internet security standards. Standards that on mass deployment make the Internet and all its users safer, indiscriminately, immediately... Recently the report 'Setting the standard. For a more Secure and Trustworthy Internet. The Identification of Pressure Points in Society to Speed up Internet Standards Deployment', was published on the IGF website. more

DNS Survey Results Pandora’s Box of Both Frightening and Hopeful Results, Says Cricket Liu

The fifth-annual survey of domain name servers (DNS) on the public Internet -- called a "Pandora's box of both frightening and hopeful results" -- was released today by The Measurement Factory in partnership with Infoblox. more

DNSSEC Deployed for .COM, Internet’s Largest Top-Level Domain

DNS Security Extensions (DNSSEC) has been deployed for .COM, Internet's largest domain extension with more than 90 million registrations. The announced was made today by VeriSign, the registry operator for .COM. more
