DNS

Old Habits Die Hard!

The new domains are coming! ?Dot-biz is going to be the next coming of dot-com?, I recently read in an article in the Denver Post. The buzz has begun. Seven new top-level domains have been approved by ICANN, the organization that governs domains, and could be available as early as spring of this year. The new domains approved are .biz, .info, .aero, .coop, .musuem, .pro, and .name. more

New gTLD SSR-2: Exploratory Consumer Impact Analysis (Part 5 of 5)

Throughout this series of blog posts we've discussed a number of issues related to security, stability, and resilience of the DNS ecosystem, particularly as we approach the rollout of new gTLDs. Additionally, we highlighted a number of issues that we believe are outstanding and need to be resolved before the safe introduction of new gTLDs can occur - and we tried to provide some context as to why, all the while continuously highlighting that nearly all of these unresolved recommendations came from parties in addition to Verisign over the last several years. more

How to Take a Proactive Approach to DNS Health

Because DNS is such an omnipresent part of modern networking, it's easy to assume that functional DNS infrastructure can be left running with minimal adjustments and only needs to be investigated in the event of a malfunction. Yet there are small telltale signs that precede DNS issues -- and knowing what they are can help to prevent disruption before it happens. more

DNS Industry Insider Summit: Fostering Collaboration Among DNS Leaders

This week, 17 individuals from about a dozen organizations in the DNS space met up in Manchester, NH at the Dyn Inc. headquarters for a first of its kind Summit for DNS industry insiders. Called "Inside Baseball," we wanted to bring people together from every spectrum of the DNS industry to inspire collaboration and innovation. more

Google as DNS, Wikileaks as PoC

Wikileaks is still accessible -- via Google. Does that change anything? For many Internet users IP addresses as well as domain names are completely transparent. Further, Google (and other search engines) and often the first stop when these users wants to find a service, or a web site. Thus, many of us discussed over the years the eventual viability of Google (... and other search engines) as "DNS" (note the "'s). Now, don't jump at my throat quite yet... more

DNS, Domain Names, and Certificates: The Missing Links in Most Cybersecurity Risk Postures

In 2019, we've seen a surge in domain name system (DNS) hijacking attempts and have relayed warnings from the U.S. Cybersecurity and Infrastructure Agency, U.K.'s Cybersecurity Centre, ICANN, and other notable security experts. Although the topic has gained popularity amongst CIOs and CISOs, most companies are still overlooking important security blind spots when it comes to securing their digital assets outside the enterprise firewalls -- domains, DNS, digital certificates. more

.COM - The Riskiest Top-Level Domain?

A couple of weeks ago, NetworkWorld published an article indicating that the .com TLD was the riskiest TLD in terms of containing code that can steal passwords or take advantage of browser vulnerabilities to distribute malware... It is unclear to me what they mean by TLD's being risky. The number of domains, 31.3% of .com's being considered risky, what does this actually mean? Is it that 31% of .com's are actually serving up malware or something similar? If so, that seems like a lot because for many of us, nearly 1 in every 3 pages that most people visit would be insecure... more

Recalibrating the DoH Debate

At the Internet Engineering Task Force (IETF) it is time we accept the wide range of drivers behind (and implications of) standards and for stakeholders to start listening to each other. A protocol recently released by the IETF, DNS over HTTPS (DoH), is at the centre of an increasingly polarised debate. This is because DoH uses encryption in the name of security and privacy and re-locates DNS resolution to the application layer of the Internet. more

Cloud Security Hinges on IP Addressing

In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more

Comcast Announces Completion of DNSSEC Deployment

Comcast, a leading ISP in the U.S., has fully deployed Domain Name System Security Extensions (DNSSEC) according to a company announcement today. Jason Livingood, Comcast's Vice President of Internet Systems writes: "As of today, over 17.8M residential customers of our Xfinity Internet service are using DNSSEC-validating DNS servers. In addition, all of the domain names owned by Comcast, numbering over 5,000, have been cryptographically signed. All of our servers, both the ones that customers use and the ones authoritative for our domain names, also fully support IPv6." more

Chuck Norris Botnet and Broadband Routers

Last week Czech researchers released information on a new worm which exploits CPE devices (broadband routers) by means such as default passwords, constructing a large DDoS botnet. Today this story hit international news... The spread of insecure broadband modems (DSL and Cable) is extremely wide-spread, with numerous ISPs, large and small, whose entire (read significant portions of) broadband population is vulnerable. more

Only Bad Actors Should Worry About the URS

With DNS abuse a topic of increased concern throughout the community, any controversy over adopting the Uniform Rapid Suspension System (URS) for all generic top-level domains (gTLDs) seems misplaced. The URS was designed as a narrow supplement to the Uniform Domain-Name Dispute Resolution Policy (UDRP), applicable only in certain tightly defined circumstances of clear-cut and incontrovertible trademark infringement involving the registration and use of a domain name. more

Towards More Efficient Registry-Registrar Relations

On the morning of Wednesday 15th October, the The Domain Name Association (the DNA) held an important working group meeting during ICANN 51 Los Angeles. The topic was to discuss several operational issues between registries and registrars. The meeting's unofficial ongoing name is the Registry-Registrar Operations Working Group. The meeting was a continuation of an inaugural meeting that was held back in June of this year, and covered in a Industry Association: An Implementation Model circulated by the DNA from September 17, by Executive Director Kurt Pritz. more

Will a Global TAR Make DNSSEC Stick?

Two US Government contractors and the National Institute of Science and Technology have released a white paper, "Statement of Needed Internet Capability," detailing possible alternatives and considerations for a Trust Anchor Repository (TAR) to support DNSSEC deployment. The document was released through the DNSSEC-Deployment Group this week with a request that it be circulated as widely as possible to gather feedback. A Trust Anchor Repository (TAR) refers to the concept of a DNS resource record store that contains secure entry point keys... more

The Harsh Reality of Spam and Online Security… Should I Stay or Should I Go?

Working in the anti-spam and online malware fight can be depressing or at best invoke multiple personality disorder. We all know things are bad on the net, but if you want a dose of stark reality, check out Brian Kreb's fantastic 'Security Fix' blog on the Washington Post site... Speaking to an old friend who asked me what I was doing these days, I recently likened the fight against this relentless onslaught to having one's pinky in a dyke, and there are days when I don't even think we have a dyke! more
