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

The Report on “Securing Cyberspace for the 44th Presidency”

A report "Securing Cyberspace for the 44th Presidency" has just been released. While I don't agree with everything it says (and in fact I strongly disagree with some parts of it), I regard it as required reading for anyone interested in cybersecurity and public policy. The analysis of the threat environment is, in my opinion, superb; I don't think I've seen it explicated better. Briefly, the US is facing threats at all levels, from individual cybercriminals to actions perpetrated by nation-states. The report pulls no punches... more

Mitigating the Increasing Risks of an Insecure Internet of Things

The emergence and proliferation of Internet of Things (IoT) devices on industrial, enterprise, and home networks brings with it unprecedented risk. The potential magnitude of this risk was made concrete in October 2016, when insecure Internet-connected cameras launched a distributed denial of service (DDoS) attack on Dyn, a provider of DNS service for many large online service providers (e.g., Twitter, Reddit). Although this incident caused large-scale disruption, it is noteworthy that the attack involved only a few hundred thousand endpoints... more

The Take Away from Global Payments Breach

Global Payments, an Atlanta-based payment card processing firm, announced yesterday that they had suffered "unauthorized access into a portion of its processing system". Sometime in early March they uncovered the attack, and there are some indications that the breach occurred between January 21st and February 25th of this year... There are a number of unverified reports that a New York City street gang with Central American ties took control of "an administrative account that was not protected sufficiently". 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

COVID Domain Registrations Surged in March

The Internet and the domain name system (DNS) have become the mainstay of the new COVID sheltered world. Afilias looked at registrations in the unrestricted domain name space, with a special focus on the popular .INFO, .PRO, .MOBI and .IO domain name extensions. The data shows that the number of website and domain registrations related to COVID and Coronavirus in these extensions is flattening after a surge in March. more

Security Firm Recovers Over 272 Million Stolen Credentials from a Collector

The latest discovery came while researchers at a security firm found a young Russian hacker bragging in an online forum that he had collected and was ready to give away a far larger number of stolen credentials that ended up totalling 1.17 billion records, Reuters reports. 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

The Root KSK Rollover? What Does It Mean for Me?

In a little over two weeks, precisely in 17 days (on 11 October 2018 at 16:00 UTC), ICANN will roll the Domain Name System Security Extensions (DNSSEC) root Key Signing Key (KSK). If you are a Domain Name System (DNS) and DNSSEC expert already engaged globally on the topic, you are certainly both well aware and ready for the rollover. This article is probably not for you! If however, you are out there focused on your day to day running or managing a DNS infrastructure... more

IS3C Report: Socio-Political and Technical Impacts of Post Quantum Cryptography Policies

At the 20th Internet Governance Forum in Lillestrøm, Norway, the UN Internet Governance Forum's dynamic coalition Internet Standards, Security and Safety (IS3C) released its new report on post-quantum policies. This report presents the findings of a collaborative study undertaken by IS3C and the French domain name registry Afnic and examines the critical need for Post-Quantum Cryptography (PQC) to achieve greater security in the ever-expanding global IoT landscape. more

Searching for Truth in DKIM: Part 2 of 5

In part 1, we explained that the DKIM "d=" value identifies the domain name which signed the message, which may be a different domain name from the author of the message. Tying the signing and author domains together will require an additional standard: Author Domain Signing Practices (ADSP). In IETF parlance, the "author domain" is the domain name in the From: header, so ADSP is a way for the author domain to publish a statement specifying whether any other domain name should ever sign a message purporting to be From: that author domain... 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

Should You Whitelist Your Vulnerability Scanning Service Provider?

Unlike consultant-led penetration testing, periodic or continual vulnerability scanning programs have to operate harmoniously with a corporation's perimeter defenses. Firewalls, intrusion prevention systems, web proxies, dynamic malware analysis systems, and even content delivery networks, are deployed to protect against the continuous probes and exploit attempts of remote adversaries -- yet they need to ignore (or at least not escalate) similar probes and tests being launched by the managed security service providers an organization has employed to identify and alert upon any new vulnerabilities within the infrastructure or applications that are to be protected. more

No Virginia, You Have No Duty to Secure Your WiFi Access Point

Every now and again a report flies across the network about the police breaking down someone's door and attempting to arrest the home owner for bad things online - assuming that whatever happened from that person's Internet connection is their fault. Now there are lots of problems with this - lots of problems. But one of the big ones is that anyone can access an open access point... more

Fixing the Internet Might Break It Worse Than It’s Broken Now

Willis Alan Ramsey, who wrote "Muskrat Love," recorded one and only one studio album. The cognoscenti of country think it's a gem, an all time top ten. There's an apocryphal story that when Ramsey was pushed to make another record he allegedly retorted, "What's wrong with the first one?" We who use the Internet every day risk losing sight of what a miracle it is, and the openness that keeps it so miraculous... We also lose sight of the fact that even as the Internet's miracles occur, it's almost always broken or malfunctioning or threatening or worse in many places along the line. more
