A substantial amount of DNS community discussion on the topic of DNS Abuse is focused on defining what is or is not DNS Abuse. The definition adopted by ICANN contracted parties, as well as the DNS Abuse Institute, is straightforward: DNS Abuse is malware, botnets, pharming, phishing, and spam where it's a vehicle for the preceding harms. There is, of course, some fuzziness on the margins, where technical harms are also using content. more
The ICANN Security and Stability Advisory Committee (SSAC) has recently published SAC105, a report on the interplay between the DNS and the Internet of Things (IoT). Unlike typical SSAC publications, SAC105 does not provide particular recommendations to the ICANN Board, but instead is informative in nature and intends to trigger and facilitate dialogue in the broader ICANN community. more
DNS is not something that most people think about when using the Internet. Neither should they have to: the DNS is just part of the infrastructure in the same way that IP addresses are. The only time a user ought to notice the DNS is when it breaks (and it should never break). If that's true, then we ought to expect any Internet client - including web browsers - to use the very same infrastructure as everything else and for the DNS resolution mechanisms to be the ones offered by the operating system. What makes browsers different? more
The Internet is slowly beginning to adopt the new DNSSEC domain names standard, but significant challenges remain. That was the main takeaway from a four-hour workshop on the technology held during the recent ICANN 41 public meeting in Singapore, which heard from many domain registries, registrars and other infrastructure providers. more
The ICC's new cyber policy reframes Internet infrastructure as crucial to prosecuting atrocities, prompting DNS operators and network providers to grapple with emerging obligations around evidence, neutrality, and cooperation in international justice. more
The Internet's Domain Name System is a modern day miracle. It may not represent the largest database that has ever been built, but nevertheless it's truly massive. And even if it's not the largest database that's ever been built, it's perhaps one of the more intensively used... Given the fragmentation of the IPv4 address space with the widespread use of various forms of address sharing, then it increasingly looks as if the DNS is the only remaining common glue that binds the Internet together as a single network. more
Microsoft announced today its plans to adopt DNS over HTTPS (DoH) protocol in Windows and will also keep other options such as DNS over TLS (DoT) on the table for consideration. more
Yesterday CommunityDNS noticed a sudden, heavy spike in traffic through its Anycast node in Hong Kong. While comfortably processing queries at 863,000 queries per second for close to 2 hours the occurrence was undeniable. While we can't say the increase in traffic was specifically due to DDoS, its sudden increase is suspicious and reminds us that DDoS is still a popular tool used by the malicious community. more
"The General Services Administration is analyzing what caused an outage of .gov websites for a few hours Wednesday morning," reports Federal Times. Officials said the problem involved so-called DNSSEC cybersecurity measures that affected access to certain .gov sites, according to GSA spokeswoman Mafara Hobson. more
EFF's Senior Legislative Counsel, Ernesto Falcon, in a post on Monday has argued that major ISPs in the U.S. -- the likes of Comcast, AT&T;, and Verizon -- are aggressively influencing legislators to stop the deployment of DNS over HTTPS (DoH), "a technology that will give users one of the biggest upgrades to their Internet privacy and security since the proliferation of HTTPS." more
Internet Society's DNSSEC Deployment Maps are now available as part of a larger set of Global Internet Maps from its annual Global Internet Report. The map is based off of the 5 stages of DNSSEC deployment that the organization tracks as part of the weekly DNSSEC deployment maps generated. more
As we start the new year, it is worth noting some of the major events and news in 2008 that shaped the industry and fueled considerable discussions. Last year's occurrences made for a very historic year, bearing the seeds of future changes for the DNS and domain name industry. more
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. more
Despite security advances over the past year, including the increased deployment of DNSSEC, pirates continue to wreak havoc on the Internet. But before you decide that Internet security innovations are futile, consider this: online criminals are just like burglars in the physical world; they don't take new ways of blocking their best efforts lying down. They come up with new and, in some cases, stronger plans of attack. more
A blog post has created some attention online through its extremely negative attitude to DNSSEC. Through the years, I have come in contact with many arguments against DNSSEC that suggest that anyone who is critical has not managed to or wanted to familiarize themselves with what DNSSEC is and does. We have received many questions concerning the article, so I feel it's appropriate to respond to the criticism. more
