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

Protecting an Enterprise from Cyber Catastrophe

We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more

Cybersecurity Considerations in the Work-From-Home Era

Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape. Over the years, cybercriminals have grown more sophisticated, adapting to changing business practices and diversifying their approaches in non-traditional ways. We have seen security threats continue to evolve in 2020, as many businesses have shifted to a work from home posture due to the COVID-19 pandemic. 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

Backlash Over Potential Firing of U.S. Election Cybersecurity’s Top Official

The Electronic Frontier Foundation (EFF), along with over forty other cybersecurity experts and organizations, are urging the White House to keep politics out of securing this month's election in the U.S. more

An Investigative Analysis of the Silent Librarian IoCs

The Silent Librarian advanced persistent threat (APT) actors have been detected once again, as the academic year started in September. With online classes increasingly becoming the norm, the group's phishing campaigns that aim to steal research data and intellectual property could have a high success rate. Dozens of phishing domain names have been reported, although some may have already been taken down. more

IoT From a Network Perspective: Learning to Navigate the New Realms

Let's play the analogy game. The Internet of Things (IoT) is probably going end up being like... a box of chocolates, because you never do know what you are going to get? a big bowl of spaghetti with a serious lack of meatballs? Whatever it is, the IoT should have network folks worried about security. Of course, there is the problem of IoT devices being attached to random places on the network, exfiltrating personal data back to a cloud server you don't know anything about. more

The Good Old Days in the Cryptography Wars

The 20th century was the golden age of surveillance. High-speed communication went either by telegraph and telephone, which needed a license from the government, or by radio, which anyone can listen to. Codes were manual or electromechanical and were breakable, e.g., the Zimmermann telegram and Bletchley Park. (The UK government spent far more effort inventing a cover story for the source of the telegram than on the break itself, to avoid telling the world how thoroughly they were spying on everyone.) more

US Election-Related Web Properties Prone to Fraud and Misinformation Due to Lack of Domain Security

The risks of fraud and disinformation in the U.S. election process have been hiding in plain sight. CSC's new research finds that a large majority of web domains closely linked to the campaign websites for Joe Biden and Donald Trump lack basic domain security protocols and are prone to domain spoofing tactics. This makes them a potential target for hackers looking to spread disinformation ahead of the election, and criminals who want to take advantage of voter intentions... more

New Data Reveals Phishing Attacks Are Bigger Than Reported, Exact Size of Problem Unknown

A group of experts from Interisle Consulting Group released a paper today, reporting a comprehensive study of the phishing landscape in 2020. The study's goal was to capture and analyze a large set of information about phishing attacks to better understand how much phishing is taking place, where it is taking place, and better ways to fight them. more

CENTR Has Released an Animated Video on ccTLDs and Their Technical Role Concerning Content

Due to increased legislative interest in this topic, CENTR says there is a pressing need for comprehensive educational material on the technical capabilities of the DNS, ccTLDs and their role in the internet ecosystem. more

A Responsible Domain Industry Needs a Responsible Registrant Appeals Process

As the steward of .ORG, Public Interest Registry is committed to serving as an "exemplary registry" for the DNS. As part of that mission, PIR published our Anti-Abuse Principles last year that serve as our north star to address questions of abuse. As PIR has stated on many occasions, generally speaking, the DNS is not the appropriate place to address questions of website content abuse because of the blunt tool we as a registry have and the collateral damage that can be caused by suspending a domain name for a piece of content. more

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. more

The Countdown Has Started – Here Come One-Year Digital Certificate Life Cycles

Apple announced its decision to trust only one-year digital certificates on its Safari browser in February 2020. This decision created a domino effect, with Mozilla and Google following suit; certificate providers announced they would not issue two-year certificates after Aug. 19, 2020. We wrote an article in March to help brands to prepare for this change. more
