DNSSEC is But One Link in the Security Chain

As the implementation of DNSSEC continues to gather momentum and with a number of ccTLDs, and the '.org' gTLD having deployed it into their production systems, I think it is worth pausing to take a look at the entire DNSSEC situation. Whilst it is absolutely clear that DNSSEC is a significant step forward in terms of securing the DNS, it is but one link in the security chain and is therefore not, in itself, a comprehensive solution to fully securing the DNS system. more

DNS Abuse Institute Launches Centralized DNS Abuse Reporting Service

The DNS Abuse Institute (DNSAI), the entity created by Public Interest Registry (PIR), today announced the launch of NetBeacon, a centralized DNS Abuse reporting service. NetBeacon was developed in collaboration with CleanDNS, an anti-abuse solution developer, which has donated the development and technology behind NetBeacon. more

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction. more

The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. 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

Rod Beckstrom’s First 100 Days at ICANN

Rod Beckstrom took over as ICANN President/CEO on July 1, 2009, so October 9th marked his 100th day in office -- and a good opportunity to examine the progress made by ICANN during his short tenure. ...to borrow an analogy from American football: when you have the ball in the Red Zone, you need to score touchdowns, not field goals. So far, under Rod's leadership, ICANN has moved down the field on a number of issues. In particular, ICANN scored a "touchdown heard round the world" by bringing the MoU/JPA to a successful conclusion. more

Industry Makes Rapid Progress on DNSSEC

DNSSEC is being rolled out quickly in top-level domain registries around the world, but there's still some way to go to encourage other Internet stakeholders to adopt the new security technology. That was one of the key takeaways from a day-long, comprehensive session on Domain Name System Security Extensions implementation worldwide, held during ICANN's public meeting in Cartagena, Colombia, last week. more

Takeaways from the DNS-OARC’s 28th Workshop

March has seen the first of the DNS Operations, Analysis, and Research Center (OARC) workshops for the year, where two days of too much DNS is just not enough! These workshops are concentrated within two days of presentations and discussions that focus exclusively on the current state of the DNS. Here are my impressions of the meeting. more

Evolution of the Dot Brand Domains in 5 Years

ICANN's last new gTLD application closed in 2012 with more than 600 brands applying for their dot brand. Dot brand domains associate a keyword or keyphrase and a brand name in a complete domain name... To understand better how the evolution of the dotBrand has been throughout these years, number of websites launched, redirects, registries etc, Dot Brand Observatory prepared a few visual graphics. more

Domain Pulse 2008: Day 2 Focuses on DNS Security

Day two of Domain Pulse 2008 last Friday (see review of day one) focused on online security issues giving the techies amongst us details of security issues, and the more policy-orientated amongst us something to chew on in a few other presentations. Kieren McCarthy, these days of ICANN, also gave some insights into the drawn out sex.com drama with more twists and turns than the average soap opera has in a year! And Randy Bush outlined the problems with IPv6. Among other presentations... more

Why SOPA Defender Joins Internet Society as Regional Director

Internet Society recently announced the appointment of former chief technology officer of Motion Picture Association of America (MPAA). The decision has raised concerns within the Internet community as Paul Brigner had campaigned for SOPA while at MPAA as well as being on record opposing net neutrality while being an official at Verizon. 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, 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

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

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
