Authenticated Resolution and Adaptive Resolution: Security and Navigational Enhancements to the DNS

The Domain Name System (DNS) has become the fundamental building block for navigating from names to resources on the internet. DNS has been employed continuously ever since its introduction in 1983, by essentially every internet-connected application and device that wants to interact online. Emerging from an era where interconnection rather than information security was the primary motivation, DNS has gradually improved its security features.

Phishing 2020: A Concentrated Dose of Badness

How much phishing is there? Where is it occurring, and why? How can it be reduced? I and my colleagues at Interisle Consulting have just published a new study called Phishing Landscape 2020, designed to answer those questions. We assembled a deep set of data from four different, respected threat intelligence providers and enriched it with additional DNS data and investigation. The result is a look at phishing attacks that occurred in May through July 2020.

Maximizing Qname Minimization: A New Chapter in DNS Protocol Evolution

Data privacy and security experts tell us that applying the "need to know" principle enhances privacy and security, because it reduces the amount of information potentially disclosed to a service provider -- or to other parties -- to the minimum the service provider requires to perform a service. This principle is at the heart of qname minimization, a technique described in RFC 7816 that has now achieved significant adoption in the DNS.

New CSC Research Finds Significant Lack of Redundancy for Enterprise DNS

As outlined in CSC's recent 2020 Domain Security Report: Forbes Global 2000 Companies, cybercriminals are disrupting organizations by attacking the protocol responsible for their online presence -- their domain name system (DNS). When a DNS is overwhelmed with traffic due to a distributed denial of service (DDoS) attack or configuration error, content and applications become inaccessible to users, affecting both revenue and reputation.

The State of DNS Abuse: Moving Backward, Not Forward

ICANN's founding promise and mandate are optimistic -- ensure a stable and secure internet that benefits the internet community as a whole. Recent months, however, have highlighted the uncomfortable truth that ICANN's and the industry's approach to DNS abuse is actually moving backward, ignoring growing problems, abdicating on important policy issues, and making excuses for not acting. Further, the impending failure of ICANN's new WHOIS policy to address cybersecurity concerns will add fuel to the fire, resulting in accelerating DNS abuse that harms internet users across the globe.

Evolving the Internet Through COVID-19 and Beyond

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.

Building a New Era of Trust on the Internet

Since Tim Berners-Lee first introduced us to the world wide web, we have seen several major phases of its growth. From the early years -- where researchers and open Internet pioneers led the way; to the dot-com boom; to the era of social media domination; the web has come a long way. While the pandemic circling the globe has undermined many critical systems and institutions of our society, I believe it also has the potential to strengthen is the resolve of the Internet community...

Technology Adoption in the Internet

How are new technologies adopted in the Internet? What drives adoption? What impedes adoption? These were the questions posed at a panel session at the recent EuroDiG workshop in June. In many ways, this is an uncomfortable question for the Internet, given the Internet's uncontrolled runaway success in its first two decades. The IPv4 Internet was deployed about as quickly as capital, expertise, and resources could be bought to bear on the problem...
