Watch Live Oct 1 - Dyn’s Techtoberfest: Internet Trends, Security, Net Neutrality and More

On Thursday, Oct 1, 2015, from 9:30am-4:30pm US EDT (UTC-4), Dyn will be holding their "TechToberFest" event in Manchester, NH, and also streaming the video live for anyone interested. There are a great set of speakers and a solid agenda. As I wrote on the Internet Society blog, I'll be part of the security panel from 3-4pm US EDT... and we who are on the panel are excited to participate just for the conversation that we are going to have! It should be fun! more

Call for Participation - DNSSEC Workshop at ICANN 56 in Helsinki, Finland on 27 June 2016

Do you have an idea for an innovative use of DNSSEC or DANE? Have you recently deployed DNSSEC or DANE and have some "lessons learned" that you could share? Did you develop a new tool or service that works with DNSSEC? Have you enabled DNSSEC by default in your products? (And why or why not?) Do you have ideas about how to accelerate usage of new encryption algorithms in DNSSEC? more

KSK Rollover, Elliptical Curve Vulnerabilities, Surveillance and Privacy. Are We Building Trust?

ICANN just recently performed a Root Zone DNS Security Extensions (DNSSEC) Key Signing Key (KSK) Rollover. The recent KSK Rollover that took place on the 11th October 2018. The KSK Rollover has been successful and congratulations are in order. The Root Zone DNSSEC Key Signing Key "KSK" is the top most cryptographic key in the DNSSEC hierarchy. The KSK is a cryptographic public-private key pair. more

Call for Participation - ICANN DNSSEC Workshop at ICANN62, Panama City

Would you like to share information about how you are using DNSSEC with the wider technical community? Do you have an idea for how to make DNSSEC or DANE work better? Or work with new applications? If so - and if you will be attending ICANN 62 in Panama City, Panama from 25-28 June 2018 - then please consider sending in a proposal to participate as a speaker in the ICANN 62 DNSSEC Workshop! more

Centralizing DNS Data for Security, Compliance, and Performance

Private DNS data lakes consolidate fragmented logs into a centralised platform, improving visibility, security, and compliance. They enable advanced analytics, strengthen threat detection, and help organisations optimise network performance in increasingly complex IT environments. 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

Overcoming DNSSEC Challenges: A Guide for TLDs

Despite offering robust protection for the Domain Name System, DNSSEC suffers from poor adoption due to its complexity, cost, and operational risks. Automation and algorithmic improvements now offer practical solutions for broader deployment. more

DNSSEC Root Signature, Almost There!

IT security specialists have known for years that the plain DNS is not to be trusted. Any hope for improvement rests on the DNSSEC protocol deployment. In this post, I will review the current status in one critical aspect, namely the DNS root signature key management. The other two foremost are the application usage of DNSSEC protocol functionality and the operational front, or the extent of deployment in the DNS infrastructure. The operational front includes the support by the DNS root nameservers, but my focus on signature key management leaves this issue aside. more

Verisign’s Role in Securing the DNS Through Key Signing Ceremonies

Every few months, an important ceremony takes place. It's not splashed all over the news, and it's not attended by global dignitaries. It goes unnoticed by many, but its effects are felt across the globe. This ceremony helps make the internet more secure for billions of people. This unique ceremony began in 2010 when Verisign, ICANN and the U.S. Department of Commerce's National Telecommunications and Information Administration collaborated... more

A Great Collaborative Effort: Increasing the Strength of the Zone Signing Key for the Root Zone

A few weeks ago, on Oct. 1, 2016, Verisign successfully doubled the size of the cryptographic key that generates DNSSEC signatures for the internet's root zone. With this change, root zone DNS responses can be fully validated using 2048-bit RSA keys. This project involved work by numerous people within Verisign, as well as collaborations with ICANN, Internet Assigned Numbers Authority (IANA) and National Telecommunications and Information Administration (NTIA). more

Why More Registries Should Be Talking About DNS Security

I've been incredibly lucky in my time at Neustar to lead both the exceptional Registry and Security teams. While these divisions handle their own unique product and service offerings, it's clear that they have some obvious crossovers in their risks, opportunities and challenges. Having been closely involved in the strategy of both these teams, it strikes me that there is more we as Registry Operators and service providers can and should be doing to align the world of cybersecurity with that of domain names. more

Trusted Notifier Arrangements Require Trust: Why Unpacking Misunderstandings Around Trusted Notifiers Is Important for Dealing With DNS-related Abuse

Domain Name System (DNS) Operators (Registries and Registrars) receive notices asking them to take action on a wide range of alleged technical and content-related abuses. However, there is a fundamental question of when it is appropriate to act at the DNS level and the evaluation of whether the alleged abuse meets a sufficient threshold for action at the DNS level. Additionally, given the volume of abuses occurring on the internet, existing resources, mechanisms, and protocols available in-house to Operators are in many cases insufficient to address abuses in a timely fashion. more

The Excruciating Slow Rise of DNSSEC: A Dialogue With Roy Arends About Myths, Realities and Hard Lessons

DNSSEC promised to secure DNS with cryptographic proof, yet messy rollouts, outages, and hype backlash ruined its reputation. This piece argues that storytelling and emotions shape adoption as much as specs, and that automation enables a reset. more

Registry Lock - or EPP With Two Factor Authentication

For the last couple of years, the most common attack vector against the DNS system is the attack against the registrar. Either the attack is on the software itself using weaknesses in the code that could inject DNS changes into the TLD registry, or social engineering the registrar support systems and the attacker receives credentials that in turn allows the attacker to perform malicious changes in DNS. DNSSEC is the common security mechanism that protects the DNS protocol, but by using the registrar attack, any changes will result in a proper working DNS delegation. more

Can We Really Blame DNSSEC for Larger-Volume DDoS attacks?

In its security bulletin, Akamai's Security Intelligence Response Team (SIRT) reported on abuse of DNS Security Extensions (DNSSEC) when mounting a volumetric reflection-amplification attack. This is not news, but I'll use this opportunity to talk a bit about whether there is a trade-off between the increased security provided by DNSSEC and increased size of DNS responses that can be leveraged by the attackers. more
