DNS Security

Noteworthy

 Over the next few years we should expect to see applications leveraging DNSSEC in ways we cannot imagine now.

 The movement is on, DNSSEC, ready set go! Just make sure you are ready when you go!

 DNSSEC technology standards have been stable and mature since 2007, with only updates, clarifications, and new functionality added since then.

 Some folks have already asked me if DNSSEC could have prevented Twitter.com traffic from being hijacked. In this case, the answer is, "No".

Cyber-Terrorism Rising, Existing Cyber-Security Strategies Failing, What Are Decision Makers to Do?

While conventional cyber attacks are evolving at breakneck speed, the world is witnessing the rise of a new generation of political, ideological, religious, terror and destruction motivated "Poli-Cyber™" threats. These are attacks perpetrated or inspired by extremists' groups such as ISIS/Daesh, rogue states, national intelligence services and their proxies. They are breaching organizations and governments daily, and no one is immune. more»

New Report on "State of DNSSEC Deployment 2016" Shows Continued Growth

Did you know that over 50% of .CZ domains are now signed with DNS Security Extensions (DNSSEC)? Or that over 2.5 million .NL domains and almost 1 million .BR domains are now DNSSEC-signed? Were you aware that around 80% of DNS clients are now requesting DNSSEC signatures in their DNS queries? And did you know that over 100,000 email domains are using DNSSEC and DANE to enable secure email between servers? more»

Call for Participation - ICANN DNSSEC Workshop at ICANN58 in Copenhagen

Do you have new information about DNSSEC or DANE that you would like to share with the wider community? Have you created a new tool or service? Have you found a way to use DNSSEC to secure some other service? Do you have new statistics about the growth or usage of DNSSEC, DANE or other related technology? If so, and if you will be in Copenhagen, Denmark, for ICANN 58 in March 2017 (or can get there), please consider submitting a proposal to speak at the ICANN 58 DNSSEC Workshop! more»

DNSSEC Activities at ICANN 57 in Hyderabad on 4-7 November 2016

Friday marks the beginning of the ICANN 57 meeting in Hyderabad, India. As per usual there will be a range of activities related to DNSSEC or DANE. Two of the sessions will be streamed live and will be recorded for later viewing. Here is what is happening. All times below are India Standard Time (IST), which is UTC+05:30. Please do join us for a great set of sessions about how we can work together to make the DNS more secure and trusted! more»

Taking a Closer Look at the Recent DDoS Attacks and What it Means for the DNS

The recent attacks on the DNS infrastructure operated by Dyn in October 2016 have generated a lot of comment in recent days. Indeed, it's not often that the DNS itself has been prominent in the mainstream of news commentary, and in some ways, this DNS DDOS prominence is for all the wrong reasons! I'd like to speculate a bit on what this attack means for the DNS and what we could do to mitigate the recurrence of such attacks. more»

Trust Isn't Easy: Drawing an Agenda from Friday's DDoS Attack and the Internet of Things

Last week, millions of infected devices directed Internet traffic to DNS service provider Dyn, resulting in a Distributed Denial of Service (DDoS) attack that took down major websites including Twitter, Amazon, Netflix, and more. In a recent blog post, security expert Bruce Schneier argued that "someone has been probing the defences of the companies that run critical pieces of the Internet". This attack seems to be part of that trend. This disruption begs the question: Can we trust the Internet? 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»

Increasing the Strength of the Zone Signing Key for the Root Zone, Part 2

A few months ago I published a blog post about Verisign's plans to increase the strength of the Zone Signing Key (ZSK) for the root zone. I'm pleased to provide this update that we have started the process to pre-publish a 2048-bit ZSK in the root zone for the first time on Sept. 20. Following that, we will publish root zones with the larger key on Oct. 1, 2016. more»

Refutation of the Worst IANA Transition FUD

Of all the patently false and ridiculous articles written this month about the obscure IANA transition which has become an issue of leverage in the partisan debate over funding the USG via a Continuing Resolution, this nonsense by Theresa Payton is the most egregiously false and outlandish. As such, it demands a critical, nearly line by line response. more»

Want to Share Info with the DNSSEC Community? ICANN57 DNSSEC Workshop Seeking Proposals by Sept 15

Do you have information or an idea you would like to share with members of the broader DNS / DNSSEC community? Have you developed a new tool that makes DNSSEC or DANE deployment easier? Have you performed new measurements? Would you like feedback about a new idea you have? Would you like to demonstrate a new service you have? If so, we're seeking proposals for the DNSSEC Workshop to be held at ICANN57 in Hyderabad, India, in early November 2016. more»
