Call for Proposals: ICANN 64 DNSSEC Workshop in Kobe, Japan (March 2019)

Will you be at the ICANN 64 meeting in March 2019 in Kobe, Japan? If so (or if you can get to Kobe), would you be interested in speaking about any work you have done (or are doing) with DNSSEC, DANE or other DNS security and privacy technologies? If you are interested, please send a brief (1-2 sentence) description of your proposed presentation before 07 February 2019. more

Google Notifying Half a Million Users Affected By DNSChanger

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

IS3C Report: Socio-Political and Technical Impacts of Post Quantum Cryptography Policies

At the 20th Internet Governance Forum in Lillestrøm, Norway, the UN Internet Governance Forum's dynamic coalition Internet Standards, Security and Safety (IS3C) released its new report on post-quantum policies. This report presents the findings of a collaborative study undertaken by IS3C and the French domain name registry Afnic and examines the critical need for Post-Quantum Cryptography (PQC) to achieve greater security in the ever-expanding global IoT landscape. more

NANOG 65 Report

NANOG 65 was once again your typical NANOG meeting: a set of operators, vendors, researchers and others for 3 days, this time in Montreal in October. Here's my impressions of the meeting... The opening keynote was from Jack Waters from Level 3, which looked back over the past 25 years of the Internet, was interesting to me in its reference to the "Kingsbury Letter". more

Registration Operations is More Than Just Registering Domain Names

Perceptions can be difficult to change. People see the world through the lens of their own experiences and desires, and new ideas can be difficult to assimilate. Such is the case with the registration ecosystem. Today's operational models exist because of decisions made over time, but the assumptions that were used to support those decisions can (and should) be continuously challenged to ensure that they are addressing today's realities. Are we ready to challenge assumptions? Can the operators of registration services do things differently? more

Why DNS Is Broken, Part 1: Trust

So this Internet thing, as we discussed in our last article, is broken. I promised to detail some of the specific things that are broken. Implicit trust is the Achilles heel of the Internet... All of the communication between the resolver and the DNS server is in plain text that can be easily seen and changed while in transit, further, the resolver completely trusts the answer that was returned... more

Looking Ahead: ICANN’s Upcoming Policy on DNS Abuse Mitigation

ICANN is finalising a policy to curb DNS abuse, aiming to preserve internet stability while defending freedom of expression. With regulatory pressure mounting, the multistakeholder model faces a critical test. more

What is Good Policy for a Domain Name Registry?

Back from the holidays I must admit I was thinking quite a bit on what is good policy for a registry? Of course I have my own personal favorites that I can not walk away from easily, but instead of thinking for too long, I decided to write down now immediately what is in my head. The main reasons for this are two: the decision by ICANN to change the rules for change in policy regarding the Add Grace Periods. more

A Closer Look at Postponing of the Root Zone KSK Rollover Decision

On Sept. 27, Internet Corporation for Assigned Names and Numbers (ICANN) announced that the first root zone Key Signing Key (KSK) rollover - originally scheduled to take place on Oct. 11 - will be postponed. Although this was certainly a difficult decision, we fully agree that erring on the side of caution is the best approach to take. In this blog post, I want to explain some of the involvement Verisign has had in KSK rollover preparations, as well as some of the recently available research opportunities which generated data that we shared with ICANN related to this decision. more

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

Video: Highlights of the DNSSEC Key Signing Ceremony

ICANN video highlighting last week's historical DNSSEC key signing ceremony held in a high security data centre located in Culpeper, VA, outside of Washington, DC. "During the ceremony, participants were present within a secure facility and witnessed the preparations required to ensure that the so-called key-signing-key (KSK) was not only generated correctly, but that almost every aspect of the equipment, software and procedures associated with its generation were also verified to be correct and trustworthy." more

DNSSEC vs DDoS Protection: Is It Really a Choice?

Within the last year or two, I've heard people express an opinion to the effect that if the domain name industry put as much focus on preventing distributed denial of service attacks as we have on implementing DNSSEC, the Internet would be a safer place. While there may be a grain of truth there, I suggest that this kind of thinking presents us with something of a false dichotomy. more

ICANN Facing Critical Choice for Plan to Change DNS Cryptographic Key

While the majority of ICANN's Security and Stability Advisory Committee (SSAC) have given the organization the green signal to roll, or change, the "top" pair of cryptographic keys used in the DNSSEC protocol, commonly known as the Root Zone KSK (Key Signing Key), five members of the committee advised against the October 11 rollover timeline. more

ICANN Begins Public DNSSEC Test Plan for the Root Zone

The deployment of Domain Name System Security Extensions (DNSSEC) for the root zone got an official start today with its public signing for the first time. DNSSEC for the root zone is a joint effort between ICANN and VeriSign, with support from the U.S. Department of Commerce to improve security of the Internet's naming infrastructure. Kim Davies, ICANN's Manager of Root Zone Services, says: "What happened today was the deliberately un-validatable root zone started being published on l.root-servers.net. It is anticipated this will be rolled out across the other root servers over the coming months. This phase is designed to identify any issues with the larger DNS response sizes associated with DNSSEC data." more
