While conventional cyber attacks are evolving at breakneck speed, the world is witnessing the rise of a new generation of political, ideological, religious, terror and destruction motivated "Poli-Cyber™" threats. These are attacks perpetrated or inspired by extremists' groups such as ISIS/Daesh, rogue states, national intelligence services and their proxies. They are breaching organizations and governments daily, and no one is immune. more
In an Internet governance agenda that treats diversity of addressing issues as the ultimate end at any cost, technology and its end-users are mere means, and much of the work that sustains the Internet is ignored entirely. As a nation, you are free to initiate different regulations, but when you start getting into the world of infrastructure, you are legislating far beyond the nation-state borders. more
The ways in which the Internet is embedded in our daily lives are too varied and numerous to catalogue. The Internet delivers information, access to goods, services, education, banking, social interaction and, increasingly, work space. The global pandemic has only heightened our dependence on the online world, which is why efforts to ensure that the Internet remains a trusted and secure environment are more important than ever. more
When we look at the intersection of cryptocurrency and domain data, we see something insidious: The prevalence of crypto-related threats. And it's not just cryptojacking. It's not even the use of cryptocurrency which has made ransomware attacks easier for threat actors to commit and all the more widespread. As with nearly every trend, there is always someone looking to capitalize on it and use it for their own, personal gain. Ever since cryptocurrency became the pandemic hobby of choice, threat actors have begun to target crypto novices for their schemes. more
Keynote speaker, and noted security industry commentator, Bruce Schneier (Co3 Systems ) set the tone for the two days with a discussion on how humans name things and the shortcomings of computers in doing the same. Names require context, he observed, and "computers are really bad at this" because "everything defaults to global." Referring to the potential that new gTLDs could conflict with internal names in installed systems, he commented, "It would be great if we could go back 20 years and say 'Don't do that'," but concluded that policymakers have to work with DNS the way it is today. more
Tonight begins the third annual SIP Network Operators Conference (SIPNOC) in Herndon, Virginia, where technical and operations staff from service providers around the world with gather to share information and learn about the latest trends in IP communications services - and specifically those based on the Session Initiation Protocol (SIP). Produced by the nonprofit SIP Forum, SIPNOC is an educational event sharing best practices, deployment information and technology updates. Attendees range from many traditional telecom carriers to newer VoIP-focused service providers and application developers. more
A recent progress report on DNSSEC adoption reveals the extent to which organizations in a number of industries are falling short of their own objectives for making Domain Name Server (DNS) infrastructure more secure. The progress report, conducted by Secure64 Software Corporation, is a follow-up to a 2010 study by Forrester Research titled, "DNSSEC Ready for Prime Time," which reported on organizations' plans to implement DNSSEC in order to shore up vulnerabilities in DNS. more
As regular readers know, ICANN holds lengthy, in-depth discussions devoted to DNSSEC at each of its three annual meetings. The half-day session held at ICANN 43 in Costa Rica last month was particularly interesting. What became clear is that the industry is quickly moving into the end-user adoption phase of global DNSSEC deployment. more
In my last article, I described efforts underway to standardize new cryptographic algorithms that are designed to be less vulnerable to potential future advances in quantum computing. I also reviewed operational challenges to be considered when adding new algorithms to the DNS Security Extensions (DNSSEC). In this post, I'll look at hash-based signatures, a family of post-quantum algorithms that could be a good match for DNSSEC from the perspective of infrastructure stability. more
It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more
In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more
It has been about six months since I got together with four of my friends from the DNS world and we co-authored a white paper which explains the technical problems with mandated DNS filtering. The legislation we were responding to was S. 968, also called the PROTECT-IP act, which was introduced this year in the U. S. Senate. By all accounts we can expect a similar U. S. House of Representatives bill soon, so we've written a letter to both the House and Senate, renewing and updating our concerns. more
There has been a lot of criticism about the worthiness of DNSSEC. Low adoption rates and resistance and reluctance by Registrars to take on the perceived burden of signing domains and passing-on cryptographic material are at the crux of the criticism. I'm a believer in DNSSEC as a unique and worthwhile security protocol and as a new platform for innovation. It's the reason I've long advocated for and continue to work toward a new model of DNSSEC provisioning. more
The deployment of Domain Security Extensions (DNSSEC) has crossed another milestone this month with the publication of DURZ (deliberately unvalidatable root zone) in all DNS root servers on 5 May 2010. While this change was virtually invisible to most Internet users, this event and the remaining testing that will occur over these next two months will dictate the ultimate success of DNSSEC deployment across the Internet. more
"The General Services Administration is analyzing what caused an outage of .gov websites for a few hours Wednesday morning," reports Federal Times. Officials said the problem involved so-called DNSSEC cybersecurity measures that affected access to certain .gov sites, according to GSA spokeswoman Mafara Hobson. more
