Content Blocking at the DNS Level in Germany

For those who follow the issue of blocking illegal content from the Internet, there is an interesting development in relation to this issue here in Germany, and I will tell you a little about it. One way to make it difficult to access illegal content is to block it directly in the DNS. But what is DNS for? Basically, it serves to translate the domain name into the IP of the server that is hosting the content. By blocking directly at the DNS level, a query to a domain will no longer bring the server's IP number, and with that, the user no longer accesses that content. more

Registrar Influence on the Domain Security Posture of the Forbes Global 2000

In the 2021 Domain Security Report, we analyzed the trend of domain security adoption with respect to the type of domain registrar used, and found that 57% of Global 2000 organizations use consumer-grade registrars with limited protection against domain and DNS hijacking, distributed denial of service (DDoS), man-in-the-middle attacks (MitM), or DNS cache poisoning. On average, the adoption of domain security controls is two times higher for enterprise-class registrars than for those using consumer-grade registrars. more

On DNS Openness

When we deregulated the telephone industry, we replaced these national monopolies and their vertically bundled structures with a collection of separate enterprises whose actions are orchestrated by market forces rather than by the dictates of the incumbent monopoly telco. This was a comprehensive upheaval to the telecommunications industry, and one aspect of this broad sweep of changes was in the role of the regulator. Previously it was a rule-based framework: Is the incumbent playing by the rules we imposed on them? more

Cryptocurrency and DNS: Phishing Domains, Cryptomining and More

When we look at the intersection of cryptocurrency and domain data, we see something insidious: The prevalence of crypto-related threats. And it's not just cryptojacking. It's not even the use of cryptocurrency which has made ransomware attacks easier for threat actors to commit and all the more widespread. As with nearly every trend, there is always someone looking to capitalize on it and use it for their own, personal gain. Ever since cryptocurrency became the pandemic hobby of choice, threat actors have begun to target crypto novices for their schemes. more

Want to Help Guide the Future of the MANRS Routing Security Initiative?

Would you like to help guide the future of the Mutually Agreed Norms for Routing Security (MANRS) initiative? As the MANRS community continues to develop new efforts to make the routing layer of the Internet more secure (ex. the equipment vendor program), would you like to help lead the work? The MANRS community is seeking volunteers for its new Steering Committee. The committee will lead the community as it evolves its governance model.  more

Numerous Lessons We Can Learn From the Facebook Outage and Its Mistakes

It was only a few weeks back, in July of this year, where I remarked that an Akamai report of an outage was unusual for this industry. It was unusual in that it was informative in detailing their understanding of the root cause of the problem, describing the response that they performed to rectify the immediate problem, the measures being undertaken to prevent a recurrence of this issue, and the longer-term measures to improve the monitoring and alerting processes used within their platform. more

Industry Insights: RDAP Becomes Internet Standard

Earlier this year, the Internet Engineering Task Force’s (IETF’s) Internet Engineering Steering Group (IESG) announced that several Proposed Standards related to the Registration Data Access Protocol (RDAP), including three that I co-authored, were being promoted to the prestigious designation of Internet Standard. Initially accepted as proposed standards six years ago, RFC 7480, RFC 7481, RFC 9082 and RFC 9083 now comprise the new Standard 95. RDAP allows users to access domain registration data and could one day replace its predecessor the WHOIS protocol. more

The Test of Time at Internet Scale: Verisign’s Danny McPherson Recognized with ACM SIGCOMM Award

The global internet, from the perspective of its billions of users, has often been envisioned as a cloud -- a shapeless structure that connects users to applications and to one another, with the internal details left up to the infrastructure operators inside. From the perspective of the infrastructure operators, however, the global internet is a network of networks. It's a complex set of connections among network operators, application platforms, content providers and other parties. more

DNS Abuse Definition: Attributes of Mitigation

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 Dark Side of Decentralized Domain Names

Decentralization is exciting. Headline-grabbing, even. After all, in a world where frustration levels are sky-high and rising, it should not come as a shock that many individuals are willing to embrace what we might call "anti-system solutions." Decentralized solutions, in our case, which come with the ambitious promise of providing everything their centralized counterpart can provide but without centralized points of failure and regulations. In our previous article, we enumerated several advantages associated with decentralized domain names. more
