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

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

An Astonishing Collaboration

Wow. It's out. It's finally, finally out... So there's a bug in DNS, the name-to-address mapping system at the core of most Internet services. DNS goes bad, every website goes bad, and every email goes...somewhere. Not where it was supposed to... I'm pretty proud of what we accomplished here. We got Windows. We got Cisco IOS. We got Nominum. We got BIND 9, and when we couldn't get BIND 8, we got Yahoo, the biggest BIND 8 deployment we knew of, to publicly commit to abandoning it entirely. It was a good day... more

PRISM and the Administration State Strikes Back

It is a safe assumption that if you are reading this post, you like technology. If that is the case, then you understand the tremendous economic, cultural, and human rights benefits an open, universal, and free Internet provides. That freedom is under attack. And it is our responsibilities, as stakeholders in a successful Internet, to balance governments and have an open dialog on the topic. more

The Cycle of E-Mail Security

Stepping back from the DMARC arguments, it occurs to me that there is a predictable cycle with every new e-mail security technology... Someone invents a new way to make e-mail more secure, call it SPF or DKIM or DMARC or (this month's mini-fiasco) PGP in DANE. Each scheme has a model of the way that mail works. For some subset of e-mail, the model works great, for other mail it works less great. more

Internet Security and the Multistakeholder Approach: Is It Attainable?

Internet Security is a topic that has drawn a lot of attention over the past year. As awareness grows that cooperation is necessary, it dawns on people that there are many and very different stakeholders involved, stakeholders that may never have met before. Let alone have cooperated. An example of an approach is the National Cyber Security Council (NCSC) that was installed in The Netherlands on 30 June. This is a high level council that will give advice to public as well as private entities on how to better secure themselves and society at large against cyber attacks and how to become more resilient. However, without the right approach it is doomed to become a talking shop. more

APNIC Labs Partners with Cloudflare for Joint DNS Research Project

APNIC Labs, the research arm of Asia-Pacific Network Information Centre, is partnering with Cloudflare for a joint research project relating to the operation of the DNS, reports Geoff Huston, APNIC's Chief Scientist. more

Internet Infrastructure: Stability at the Core, Innovation at the Edge (Part 2 of 5)

For nearly all communications on today's Internet, domain names play a crucial role in providing stable navigation anchors for accessing information in a predictable and safe manner, irrespective of where you're located or the type of device or network connection you're using. Over the past 15 years hundreds of millions of domain names have been added to the Internet's Domain Name System (DNS), and well over two billion (that's Billion!) new users, some ~34 percent of the global population, have become connected. more

Eugene Kaspersky: World Needs International Agreements On Cyber-Weapons

Eugene Kaspersky has warned global leaders that the world needs international agreements about cyber-weapons in the same way as it needs agreements about nuclear or biological weaponry. The chairman and chief executive officer of Kaspersky Lab, warned delegates at CeBIT Australia that cyber-warfare and terrorism was the number one internet threat facing the world today. He said the Stuxnet industrial virus had demonstrated that cyber-weapons were capable of damaging physical infrastructure, and were "a thousand times cheaper" to develop than conventional weaponry. more

Is Your New TLD Protected Against Phishing and Malware?

Until now, the criminals behind malware and phishing have had only 22 generic top-level domain names (TLDs) to abuse -- names like .com, .net or .org. But with hundreds of new TLDs entering the marketplace, e.g. .buzz, .email, and .shop, there are many more targets than ever... What can attackers do with domain names? more

EU’s Cyber Security Agency Identifying Five Areas as Critical IT Security

The EU's 'cyber security' Agency ENISA (The European Network and Information Security Agency) has launched a new report concluding that the EU should focus its future IT security research on five areas: cloud computing, real-time detection and diagnosis systems, future wireless networks, sensor networks, and supply chain integrity. more

ICANN Releases Paper on Domain Name Security

Today ICANN releases a paper with the title "DNSSEC @ ICANN - Signing the root zone: A way forward toward operational readiness". The paper explains in more detail than earlier documents what ICANN view on signing of the root zone is. I think the key points mentioned in this paper are true, and in general, I think this document is a good read. It is not long, and summarizes what I would call the current view is. more

Facebook Apps on Any Website: A Clever Move? Or a Security Nightmare?

Well, given the amount of malicious JavaScript, malware, and other possibilities to use Facebook (and other similar social networking platforms) for abuse, I certainly wouldn't categorize this news as a "clever move"... In fact, I foresee this as an extraordinarily short-sighted move with far-reaching security implications -- which will allow the levels of malicious abuse to reach new heights. more

Neelie Kroes, the EU, Cloud Computing, Regulation and Good Ears

In her blog EU Commissioner Neelie Kroes blogs on her stance on cloud computing. In short: this is a good development which the EU will embrace and advocate, but may need regulation in order to ensure a safe environment for industry and individuals in the cloud. Here's some thoughts on that. more

The Worm and the Wiretap

According to recent news reports, the administration wants new laws to require that all communications systems contain "back doors" in their cryptosystems, ways for law enforcement and intelligence agencies to be able to read messages even though they're encrypted. By chance, there have also been articles on the Stuxnet computer worm, a very sophisticated piece of malware that many people are attributing to an arm of some government. The latter story shows why cryptographic back doors, known generically as "key escrow", are a bad idea. more
