Remote Work Demands Encryption

Now that we are all working from home (WFH), the need for encryption must also increase in priority and awareness. Zoom's popular video conferencing solution got in hot water because they promised "end-to-end" encryption but didn't deliver on it - prompting some organizations to ban it from use altogether. Encryption protects confidential information from being exposed in transmission, providing a secure way for the intended recipient to get the information without snooping by others. more

The True Effect of Corona on the DNS

In recent weeks we've seen a range of press articles, security blogposts and public statements addressing real or perceived issues with network capacity and the domain name system (DNS) in particular. These range from concerns about the resilience of the DNS with questions on the impact of the number of registrations to news indicating that a tidal wave of fraud and abuse is hitting the world. more

DoH Might Not Be the Answer After All

DNS-over-HTTPs (DoH) has sometimes been regarded as the next big thing in web security. The system, it's been argued, can help to defeat many common types of cyberattack -- and particularly DNS cache poisoning and MITM eavesdropping. Presumably, this is the reason that both Google and Mozilla implemented DoH in their browsers (Chrome and Firefox, respectively) at the end of last year. In reality, though, it's far from clear that DoH is a solution to any real-world problem. more

Five Security Blind Spots from Prolonged Implementation of a Business Continuity Plan Amid COVID-19

The novel coronavirus outbreak (COVID-19) has prompted many organizations in Mainland China and Hong Kong to execute their business continuity plan (BCP). During the last epidemic in 2003, the SARS outbreak lasted for nine months – and with an infection rate that is increasing rapidly, this new coronavirus has the potential to cause prolonged periods of commercial disruption, and heavy reliance on BCPs. more

Call for Participation – ICANN DNSSEC and Security Workshop at ICANN67, Cancun, Mexico

The ICANN Security and Stability Advisory Committee (SSAC) and the Internet Society Deploy360 Programme are planning a DNSSEC and Security Workshop during the ICANN67 meeting held from 07-12 March 2020 in Cancun, Mexico. The original DNSSEC Workshop has been a part of ICANN meetings for many years and has provided a forum for both experienced and new people to meet, present, and discuss current and future DNSSEC deployments. 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

Recognizing Lessons Learned From the First DNSSEC Key Rollover, a Year Later

A year ago, under the leadership of the Internet Corporation for Assigned Names and Numbers (ICANN), the internet naming community completed the first-ever rollover of the cryptographic key that plays a critical role in securing internet traffic worldwide. The ultimate success of that endeavor was due in large part to outreach efforts by ICANN and Verisign which, when coupled with the tireless efforts of the global internet measurement community, ensured that this significant event did not disrupt internet name resolution functions for billions of end users. more

Microsoft Announces Plans to Adopt DoH in Windows

Microsoft announced today its plans to adopt DNS over HTTPS (DoH) protocol in Windows and will also keep other options such as DNS over TLS (DoT) on the table for consideration. more

DNS Wars

The North American Network Operators' Group (NANOG) is now quite an institution for the Internet, particularly in the North American Internet community. It was an offshoot of the Regional Techs meetings, which were part of the National Science Foundation Network (NSFNET) framework of the late 80s and early 90s. NANOG has thrived since then and is certainly one of the major network operational forums in today's Internet – if not the preeminent forum for network operators for the entire Internet. more

EFF: For ISPs to Retain Power to Censor the Internet, DNS Needs to Remain Leaky

EFF's Senior Legislative Counsel, Ernesto Falcon, in a post on Monday has argued that major ISPs in the U.S. -- the likes of Comcast, AT&T;, and Verizon -- are aggressively influencing legislators to stop the deployment of DNS over HTTPS (DoH), "a technology that will give users one of the biggest upgrades to their Internet privacy and security since the proliferation of HTTPS." more

The U.S. House Judiciary Committee Is Investigating Google’s Plans to Implement DNS Over HTTPS

The U.S. House Judiciary Committee is investigating Google's plans to implement DNS over HTTPS (DoH) in Chrome according to a report by the Wall Street Journal over the weekend. more

Call for Participation – ICANN DNSSEC and Security Workshop at ICANN66, Montreal, Canada

The ICANN Security and Stability Advisory Committee (SSAC) and the Internet Society Deploy360 Programme are planning a DNSSEC and Security Workshop on Wednesday, 06 November 2019, during the ICANN66 meeting held from 02-07 November 2019 in Montreal, Canada. The original DNSSEC Workshop has been a part of ICANN meetings for many years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. more

DoH Creates More Problems Than It Solves

Unlike most new IETF standards, DNS over HTTPS has been a magnet for controversy since the DoH working group was chartered on 2017. The proposed standard was intended to improve the performance of address resolutions while also improving their privacy and integrity, but it's unclear that it accomplishes these goals. On the performance front, testing indicates DoH is faster than one of the alternatives, DNS over TLS (DoT). more

DoT and DoH Guidance: Provisioning Resolvers

As part of a larger effort to make the internet more private, the IETF defined two protocols to encrypt DNS queries between clients (stub resolvers) and resolvers: DNS over TLS in RFC 7858 (DoT) and DNS over HTTPS in RFC 8484 (DoH). As with all new internet protocols, DoT and DoH will continue to evolve as deployment experience is gained, and they're applied to more use cases. more
