Fine Grained Mail Filtering With IPv6

One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam. more

.nxt Conference Inspires and Informs New gTLD Debate

The first-ever .nxt conference recently concluded in San Francisco. The conference featured two days of productive, educational, and passionate discussion about the business of new generic top-level domains (gTLDs). While ICANN's public meetings have recently focused on debating the policies that will go into its gTLD Applicant Guidebook, the .nxt meeting moved the discussion into the future to tackle the issue of what to do when the program has actually launched... more

The Hack Will Be a Costly Affair for Optus

More and more information is becoming available about the breach of Optus (Australia's second-largest telco). It looks like the hacker is more of an amateur than a professional criminal or a "state actor." This makes the hack even more worrisome. It looks as though Optus didn't have its security house in order. This makes the issue all the more painful for the company. It will dent its reputation, and customers could become somewhat wary about dealing with the company. more

Marketo’s Path to Being Acquired

Happy Early Memorial Day. Once an ESP or marketing automation company declares itself for sale, there seems to be a mass exodus by investors, which sends up a red flag, (well in this case, a red & white striped flag). This past week there were rumblings about the potential suitors for Marketo. While it is rumored that German company SAP is the front-runner, there are many other potential suitors circling the marketing automation software company. more

Web Server Botnets and Server Farms as Attack Platforms

Are file inclusion vulnerabilitiess equivalent to remote code execution? Are servers (both Linux and Windows) now the lower hanging fruit rather than desktop systems? In the February edition of the Virus Bulletin magazine, we (Kfir Damari, Noam Rathaus and Gadi Evron (me) of Beyond Security) wrote an article on cross platform web server malware and their massive use as botnets, spam bots and generally as attack platforms. Web security papers deal mostly with secure coding and application security. In this paper we describe how these are taken to the next level with live attacks and operational problems service providers deal with daily. more

Name Collisions, Why Every Enterprise Should Care (Part 3 of 5)

Do you recall when you were a kid and you experienced for the first time an unnatural event where some other kid "stole" your name and their parents were now calling their child by your name, causing much confusion for all on the playground? And how this all made things even more complicated - or at least unnecessarily complex when you and that kid shared a classroom and teacher, or street, or coach and team, and just perhaps that kid even had the same surname as you, amplifying the issue! What you were experiencing was a naming collision (in meatspace). more

Considerations on the High-Level Panel’s “Internet Governance Forum Plus” Model

The Fourteenth Annual Meeting of the Internet Governance Forum (IGF) will convene in Berlin three weeks from tomorrow. One of the highlights of the meeting could be the main session on Internet Governance and Digital Cooperation that is to be held on Day 1, 26 November 2019. The session is to consider some of the recommendations contained in the June report from the UN Secretary-General's High-level Panel on Digital Cooperation, most notably the panel's proposal to revamp the IGF... more

To Tax or Not to Tax

Well it is not new that the US has always maintained that the Internet should be a tax free zone as per the US Congress's Tax Freedom Act 1998 which following expiry continued to be reauthorized and its most recent re-authorization (legal speak for extension) was in October 2007 where this has been extended till 2014. It is unclear whether there will be another extension post 2014. There is a moratorium on new taxes on e-commerce, and the taxing of internet access via the Tax Freedom Act. more

A Transport Protocol’s Perspective on Optimizing Starlink Performance

Digital communications systems always represent a collection of design trade-offs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium. more

Consensus Polling: ALAC Shows the Way

ICANN is about to make the jump from "merely excavating" to efficiently mining top-quality jewels. I say this because ICANN's At-Large Advisory Committee (ALAC) has reached unanimous consensus on their internal Self Review. As the New Zealand meeting drew to a close, a weary ALAC was ready to give up on creating a consensus Self Review. The familiar ICANN collaborative process of emailing Word attachments had "excavated" ALAC into the also familiar ICANN mire of "deeply divided over competing versions." more

DNA University Launches to Support Domain Name Industry

In pursuit of continued domain name industry success, the Domain Name Association (DNA) is delighted to announce the launch of the next industry resource -- the DNA University. The aim of the DNA University is to establish a dedicated education platform to facilitate the exchange of ideas, best-practice methodologies and continued development of the industry's combined expertise. To this end, the DNA University will offer stakeholders an opportunity to share their experiences, learn from each other and provide a forum to incubate concepts that will advance the domain name industry. more

IPv6: The Summer It Finally Happened

A decade old guessing game finally came to an end during these 2012 summer months. America was supposed to be hopelessly behind while Europe had not much to show after a decade of spending lavishly EU money on IPv6 related projects. China and Japan were thought to be light years ahead of everybody else. But in the end, it was the might of the American Content Industry that tipped the scales. more

Averting the Internet Meltdown

A call to action went out: a small, California-based organization called People for Internet Responsibility (PFIR) posted an announcement for an urgent conference - "Preventing the Internet Meltdown." The meltdown that PFIR envisioned was not an impending technical malfunction or enemy attack. Instead, conference organizers foresaw "risks of imminent disruption" to the Internet that would come from an unlikely sector: government officials and bureaucrats working on the unglamorous-sounding problems of Internet Governance. more

Is the Defense Innovation Unit’s Hybrid Space Architecture the “ARPANET” of Space and Will It Run on Aalyria Spacetime?

The goal of the Defense Innovation Unit (DIU) of the Department of Defense is to strengthen our national security by accelerating the adoption of commercial technology throughout the military and strengthening our allied and national security innovation bases. Space is one of its areas of focus and two of the space "lines of effort" are multi-orbit operations and logistics and hardware-to-software transformation modernization. more

GeoTLDs: Diversity is Key

The 2004 new sTLD round brought about a new type of TLD in the form of .asia and .cat. As we always struggle for words to capture their nature, I call them "geoTLDs". Culture, language and ethnicity are also part of geography. Contrary to ccTLDs, geoTLDs do not have a territorial meaning. They are a wonderful addition to the Internet as they provide a way to demonstrate one's commitment to a community that is not defined by borders, yet linked to where the individual chooses to be. ...Will they be? They will, unless we do the wrong thing now. more
