DNS Security

Responsibilities of the DNS: “Oh YES you will!”, “Oh NO you will not!”

What is the responsibility of the DNS? Should the DNS be responsible for policing traffic across its infrastructure? Should the blocking and blacklisting of names or throttling of query packets be the responsibility of the DNS? From experience I know my opening paragraph has started passionate debates in more than one section of this globe. We at CommunityDNS have found ourselves right in the middle of such heated debates. "Oh YES you will!", "Oh NO you will not!"

Beyond the Top Level: DNSSEC Deployment at ICANN 40

I recently wrote about the encouraging level of DNSSEC adoption among top-level domain name registries, and noted that adoption at the second level and in applications is an important next step for adding more security to the DNS. The root and approximately 20 percent of the top level domains are now signed; it is time for registrars and recursive DNS servers operated by the ISPs to occupy center stage.

Death of the PKI Dragons?

The recent attack on the Comodo Certification Authority has not only shown how vulnerable the current public key infrastructure is, but also that the protocols (e.g., OSCP) used to mitigate these vulnerabilities once exploited, are not in use, not implemented correctly or not even implemented at all. Is this the beginning of the death of the PKI dragons and what alternatives do we have?

DNSSEC Deployment Reaching Critical Mass

Less than nine months after the DNS root was signed, the rollout of DNSSEC across the Internet's top-level domains is approaching the tipping point. Thanks to the combined efforts of registries around the world, the new security protocol will soon be available to the majority of domain name registrants in almost a quarter of all TLDs.

COICA and Secure DNS

As a strong proponent of the private right of action for all Internet endpoints and users, I've long been aware of the costs in complexity and chaos of any kind of "blocking" that deliberately keeps something from working. I saw this as a founder at MAPS back in 1997 or so when we created the first RBL to put some distributed controls in place to prevent the transmission of unwanted e-mail from low reputation Internet addresses. What we saw was that in addition to the expected costs (to spammers) and benefits (to victims) of this new technology there were unintended costs to system and network operators whose diagnostic and repair work for problems related to e-mail delivery was made more complex because of the new consideration for every trouble ticket: "was this e-mail message blocked or on purpose?"

The Real Deployment Issue

When I see glib talk about the inevitable transition to IPv6 or DNSSEC, I have to wonder what industry people think they are working in. Let me give an example that has nothing to do with networking: storage capacity. Now if there is one constant that everyone in the computing industry can agree on it is that they expect storage media capacity to increase.

DNSSEC - Let’s Stay the Course!

I don't know about you, but I'm starting to think that DNSSEC being so hot these days is a mixed blessing. Yes, it's wonderful that after so many years there is finally broad consensus for making DNSSEC happen. But being so prominent also means the protocol is taking shots from those who don't want to make the necessary software, hardware and operational modifications needed. And DNSSEC has taken some shots from those who just want to be contrarian.

The Dark Internet

I consult on communication issues for Neustar, an Internet infrastructure company. As most CircleIDers know, Neustar works behind the scenes to ensure the smooth operation of many critical systems like DNS, .us and .biz, local number portability and digital rights management. One of the cool things about working for them is the chance to attend the events they sponsor. Last week Neustar held a security briefing for senior federal IT personnel focused on Cybersecurity and Domain Name System Security Extensions (DNSSEC)...

2010 Domain Name Year in Review - Oh, What A Year It Was!

Many of us were expecting radical changes in 2010 to the domain name market. There definitely were some of those -- just not the ones I expected. From the seizure of domains names by the US Government to ICANN's removal of restrictions on Registry/Registrar cross-ownership, 2010 was a year full of surprises. In this post, I've compiled what I think were the biggest domain name stories in 2010.
