Authenticated Resolution and Adaptive Resolution: Security and Navigational Enhancements to the Domain Name System

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. DNS has also gradually enhanced its navigational capabilities, as computing costs have decreased over the decades. And thanks to further developments that are now underway, new…

Harnessing the Momentum of Women in Cybersecurity

This week, some of the brightest subject matter experts from across the U.S. and beyond gathered virtually to talk about women in cybersecurity, recognizing that the internet is filled with both opportunities and risks, and that it’s up to all of us to defend, protect and secure critical internet infrastructure. Called Uniting Women in Cyber (UWIC), the organization’s third annual symposium is focused on celebrating successes of women leaders thriving in today’s cybersecurity ecosystem and advocating for women to reach critical leadership roles in the cybersecurity field. Verisign supports UWIC…

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. Qname minimization alters the process of DNS resolution by limiting the content of DNS queries to the minimum…
