Verisign Outreach Program Remediates Billions of Name Collision Queries

A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. more

Newer Cryptographic Advances for the Domain Name System: NSEC5 and Tokenized Queries

In my last post, I looked at what happens when a DNS query renders a "negative" response -- i.e., when a domain name doesn't exist. I then examined two cryptographic approaches to handling negative responses: NSEC and NSEC3. In this post, I will examine a third approach, NSEC5, and a related concept that protects client information, tokenized queries. The concepts I discuss below are topics we've studied in our long-term research program as we evaluate new technologies. more

Cryptographic Tools for Non-Existence in the Domain Name System: NSEC and NSEC3

In my previous post, I described the first broad scale deployment of cryptography in the DNS, known as the Domain Name System Security Extensions (DNSSEC). I described how a name server can enable a requester to validate the correctness of a "positive" response to a query -- when a queried domain name exists -- by adding a digital signature to the DNS response returned. more

The Domain Name System: A Cryptographer's Perspective

As one of the earliest protocols in the internet, the DNS emerged in an era in which today's global network was still an experiment. Security was not a primary consideration then, and the design of the DNS, like other parts of the internet of the day, did not have cryptography built in. Today, cryptography is part of almost every protocol, including the DNS. And from a cryptographer's perspective, as I described in my talk at last year's International Cryptographic Module Conference (ICMC20), there's so much more to the story than just encryption. more

.com Is A Clear and Present Danger to Online Safety

"The Internet is the real world now." This assessment was offered by Protocol, a technology industry news site, following the very real violence on Capitol Hill during the counting of the electoral college votes that officially determines the next president of the United States. The media outlet went on to say that, "[t]he only difference is, you can do more things and reach more people online -- with truth and with lies -- than you can in the real world." more

2020 Domain Name Year in Review

2020 - a year like no other. The impact of COVID on the domain name industry was felt far and wide as ICANN meetings were held virtually, travel was cancelled, TLD launches were delayed, the topic of domain name abuse was front and center, and we all tried to navigate a "new" normal. Unlike many sectors, the domain name industry was fortunate and, in many ways, survived 2020 unscathed. Much of our industry was able to continue working from home after an initial period of adjustment. more

NTIA Objects to Planned o.com Auction

According to media sources, the National Telecommunications and Information Administration (NTIA) wrote to Verisign last Friday, objecting to the company's plan to auction o.com to the highest bidder. The planned release for o.com - described by the Second Amendment to the .com Registry Agreement and intended as a pilot for the remaining reserved single-character .com names - involved an opaque consideration process that ignored community input and set aside hard-won trademark protections developed by stakeholders in order to maximize dollars earmarked for an unidentified cadre of non-profit organizations. more

Cast Your .vote for the Most Interesting New gTLD Development in Q4

2020 has been extremely eventful, so it follows that the domain industry has continued to experience perpetual change, progress and uncertainty in the last three months of the year. In our Q4 New gTLD Quarterly Report, MarkMonitor experts analyze topical registration activity, launch information, .brand growth and DNS abuse, and share a list of upcoming industry meetings for 2021. more

DNS Oblivion

Technical development often comes in short, intense bursts, where a relatively stable technology becomes the subject of intense revision and evolution. The DNS is a classic example here. For many years this name resolution protocol just quietly toiled away. The protocol wasn't all that secure, and it wasn't totally reliable, but it worked well enough for the purposes we put it to. more

97% of All Global 2000 Companies at Risk from SAD DNS Attack

There is a new threat in town known as "SAD DNS" that allows attackers to redirect traffic, putting companies at risk of phishing, data breach, reputation damage, and revenue loss. What is SAD DNS? No, it isn't the domain name system (DNS) feeling moody, but an acronym for a new-found threat -- "Side-channel AttackeD DNS" discovered by researchers that could revive DNS cache poisoning attacks. more

A Balanced DNS Information Protection Strategy: Minimize at Root, TLD; Encrypt When Needed Elsewhere

Over the past several years, questions about how to protect information exchanged in the DNS have come to the forefront. One of these questions was posed first to DNS resolver operators in the middle of the last decade, and is now being brought to authoritative name server operators: "to encrypt or not to encrypt?" It's a question that Verisign has been considering for some time as part of our commitment to security, stability and resiliency of our DNS operations and the surrounding DNS ecosystem. more

An Innovative Framework That Will Help the IoT Industry Scale Into the Billions

The Internet of Things (IoT) is on an explosive growth trajectory. According to Transforma Insights, the number of IoT-connected devices is projected to increase to 24.1 billion worldwide by 2030. That's almost a three-fold increase from 2019. Much of this growth will be fueled by the coming 5G revolution, which will enable businesses and consumers to take advantage of a wide range of increasingly sophisticated connected devices. more

ICANN Should Keep Content Regulation and Other Arbitrary Rules Out of Registry Contracts

The domain name system is not the place to police speech. ICANN is legally bound not to act as the Internet's speech police, but its legal commitments are riddled with exceptions, and aspiring censors have already used those exceptions in harmful ways. This was one factor that made the failed takeover of the .ORG registry such a dangerous situation. But now, ICANN has an opportunity to curb this abuse and recommit to its narrow mission of keeping the DNS running... more

Holiday Shoppers Beware: Tips on Protecting Brand Owners and Consumers from Domain Security Threats

With the COVID-19 pandemic persisting, online shopping will be the preferred method for the 2020 holiday shopping season. While staying home to shop is the safest option right now, it means consumers are more vulnerable to online fraud, counterfeits, and cyber crime. Increased online activity provides opportunities for unscrupulous infringers to abuse trusted brand names to drive visitors to their own fraudulent content. more

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. more
