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

Developing Internet of Things Building Blocks

The Internet is undergoing an evolutionary transformation resulting from the explosive growth of things that are interconnected. From single purpose sensors through wearable technologies to sophisticated computing devices, we are creating, exchanging, and consuming more data at rates that would have been inconceivable just a decade ago. The market suggests the average consumer believes this is the best world possible. As technologists, we have a responsibility to consider if we are building an Internet that is in the best interest of the user. more

ICANN 56 in Helsinki - Schedule of DNSSEC Activities

The ICANN 56 meeting takes place in Helsinki, Finland, from June 27-30 and while it is a smaller "policy forum" style of meeting, there will still be some activities related to DNSSEC, DANE and DNS security in general. DNSSEC Workshop The DNSSEC Workshop will take place on the morning of Monday, 27 June 2016. All times are Eastern European Summer Time (EEST), which is UTC+3. more

The Path to DNS Privacy

The DNS is normally a relatively open protocol that smears its data (which is your data and mine too!) far and wide. Little wonder that the DNS is used in many ways, not just as a mundane name resolution protocol, but as a data channel for surveillance and as a common means of implementing various forms of content access control. But all this is poised to change. more

Increasing the Strength of the Zone Signing Key for the Root Zone

One of the most interesting and important changes to the internet's domain name system (DNS) has been the introduction of the DNS Security Extensions (DNSSEC). These protocol extensions are designed to provide origin authentication for DNS data. In other words, when DNS data is digitally signed using DNSSEC, authenticity can be validated and any modifications detected. more
