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
The year 2010 is turning out to be the "year of DNSSEC" from Registry implementations, Registrar implementations, ISP support, to the Root being signed this summer. Because we are dealing with such critical infrastructure, it is important to not lose sight of careful implementations. more
For several years, many within ICANN circles have raised concerns about the escalating nature of domain name system (DNS) abuse. While some strides were made toward a safer DNS, new data - this time from a comprehensive study of DNS abuse by the European Union - demonstrates that abuse remains a frustratingly obstinate problem that requires urgent attention. We've seen some registries and registrars testing innovative industry-led initiatives in an effort to address the issues. more
FireEye announced a new piece of malware yesterday named MULTIGRAIN. This nasty piece of code steals data from Point of Sale (PoS) and transmits the stolen credit card numbers by embedding them into recursive DNS queries. While this was definitely a great catch by the FireEye team, the thing that bothers me here is how DNS is being used in these supposedly restrictive environments. more
"Is Your Internet Up-To-Date?" Does your existing Internet connection work with IPv6 and DNSSEC? Do your web sites support IPv6, DNSSEC and TLS? Is there a quick way to find out? Earlier this month a new site, Internet.nl, was launched to make this all easy for anyone to test. All you do is visit the site at en.internet.nl (also available in Dutch) and just follow the very easy links. more
A small but intriguing paragraph in the VeriSign settlement says that ICANN gets to maintain the root zone. I thought they did now, but I guess VRSN does, following advice from ICANN. This has two and a half effects. The most obvious is political -- if ICANN rather than VRSN is distributing the root zone, it removes the symbolic significance of VeriSign's A root server. The second is DNSSEC key management. Until now, the contents of the root zone have been pretty boring, a list of names and IP addresses of name servers. If DNSSEC is deployed in the root, which is not unlikely in the next few months, ICANN rather than VeriSign will hold the crypto keys used to sign the root zone. If a tug of war develops, whoever holds the keys wins, since without the keys, you can't publish a new version of the root with changed or added records unless you publish your own competing set of keys and can persuade people to use them. more
Earlier this week in a press release, VeriSign said that they are selling their SSL certificate business to Symantec. VeriSign is the dominant player in this market, having absorbed competitor Thawte in 1999, and Geotrust in 2006. Three years ago, when VeriSign decided to divest its non-core businesses, they kept the certificate business. So what's changed? more
The recent NANOG 61 meeting was a pretty typical NANOG meeting, with a plenary stream, some interest group sessions, and an ARIN Public Policy session. The meeting attracted some 898 registered attendees, which was the biggest NANOG to date. No doubt the 70 registrations from Microsoft helped in this number, as the location for NANOG 61 was in Bellevue, Washington State, but even so the interest in NANOG continues to grow... more
In today's interconnected world, your business's online identity is increasingly more vulnerable than ever. With the rapid advancement of AI and 6G technologies, cyber threats are evolving at an alarming rate, making it critical to protect your brand's digital presence. How can businesses proactively safeguard their online identity in this changing landscape? more
The domain name system (DNS) is vital for businesses as it facilitates customer access to online services and resources. Strategic DNS management plays a pivotal role in cybersecurity, safeguarding against threat vectors and ensuring secure global connectivity across online channels including apps, email, websites, application programming interfaces (APIs) and more. more
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. more
The quantum computing era is coming, and it will change everything about how the world connects online. While quantum computing will yield tremendous benefits, it will also create new risks, so it's essential that we prepare our critical internet infrastructure for what's to come. That's why we're so pleased to share our latest efforts in this area, including technology that we're making available as an open source implementation to help internet operators worldwide prepare. more
A recent report by NS1 provides a comprehensive look at global DNS traffic trends. It reveals that public resolvers dominate the internet, accounting for nearly 60% of recursive DNS usage. Telecom giants represent nearly 9%, with Google the clear front-runner at a little over 30%, followed by Amazon Web Services at 16%. more
As we approach four months since the WHO declared COVID-19 to be a pandemic, and with lockdowns and other restrictions continuing in much of the world, it is worth reflecting on how the Internet has coped with the changes in its use, and on what lessons we can learn from these for the future of the network. The people and companies that build and operate the Internet are always planning for more growth in Internet traffic. more
Cybercriminals live by the tenet "If it ain't broke, don't fix it." They'll use the same tactics repeatedly until they no longer work, then switch things up. That's why CISOs and their security teams maintain constant vigilance. Underscoring this, recent analysis of global DNS activity found that new domains continue to be a major tactic for bad actors. more
