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…

DNS: An Essential Component of Cloud Computing

The evolution of the internet is anchored in the phenomenon of new technologies replacing their older counterparts. But technology evolution can be just as much about building upon what is already in place, as it is about tearing down past innovations. Indeed, the emergence of cloud computing has been powered by extending an unlikely underlying component: the more than 30-year-old global Domain Name System (DNS). The DNS has offered a level of utility and resiliency that has been virtually unmatched in its 30-plus years of existence. Not only is this…

Verisign Expands MANRS Relationship to Strengthen Global Routing Security

Verisign has been involved with an initiative known as Mutually Agreed Norms for Routing Security, or MANRS, since its inception. MANRS, which is coordinated by the Internet Society, focuses on strengthening the security and resiliency of IP networks throughout the world by identifying and providing best practices for mitigating common routing security threats. MANRS began as a collaboration among network operators and internet exchange providers, with Verisign formally becoming a participant in its Network Operator Program in 2017. Since then, with the help of Verisign and other MANRS participants, the…
