Cyber Terrorism Is a Real Threat, and for the First Time Both Russia and the US Acknowledge It

Eugene Kaspersky, CEO and co-founder of Internet security giant Kaspersky Lab said last week that "terrorists could build a botnet that could bring down the entire Internet structure". Mr. Kaspersky ended his speech with the statement that "a global cyber police force, and global cooperation between law enforcement agencies and governments is needed". This goes very much in accordance with some of the conclusions in the Cyberspace Policy Review more

Fifty Years On – What to Expect in the Next 50 Years of the Internet

When did the Internet begin? It all gets a bit hazy after so many years, but by the early 1970s, research work in packet-switched networks was well underway, and while it wasn't running TCP at the time (the flag day when the ARPANET switched over to use TCP was not until 1 January 1983) but there was the base datagram internet protocol running in the early research ARPA network in the US. Given that this is now around 50 years ago, and given that so much has happened in the last 50 years, what does the next 50 years have in store? 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

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

Four New Generic Top Level Domains

At its meeting in Durban, ICANN signed contracts with the applicants for four new top level domains. The new domains are ????, which means "web" in Arabic, ?????? and ????, which mean "online" and "site" in Russian, and ??, which means "game" in Chinese. They should give us an interesting hint about the future of the new TLDs, because all four are utterly, totally, generic. more

Unintended Consequences of Submarine Cable Deployment on Internet Routing

The network layer of the Internet routes packets regardless of the underlying communication media (Wifi, cellular telephony, satellites, or optical fiber). The underlying physical infrastructure of the Internet includes a mesh of submarine cables, generally shared by network operators who purchase capacity from the cable owners. As of late 2020, over 400 submarine cables interconnect continents worldwide and constitute the oceanic backbone of the Internet. 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

Project 2025: The Internet and Cybersecurity

As the saying goes, elections have consequences. The consequences are underscored in the recent U.S. Presidential election and the potential impact on the Internet, infrastructure and cybersecurity. In the context of the CircleID global community, it seems worth asking where things are headed? It does beg for an analysis of what is actually proposed in Presidential Transition Project 2025 related to things internet and cybersecurity. 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

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

ICANN’s Tokyo Meeting Provides a Little More Clarity on the New gTLD Program

New gTLDs continue to be a major topic of discussion within ICANN circles, and the regional meeting currently underway in Tokyo has revealed some interesting updates for potential applicants. ICANN's Chief gTLD Registry Liaison, Craig Schwartz, delivered a great presentation on the progress being made behind closed doors at ICANN and provided the attendees with an insight into a couple of key changes that are likely to be seen in the Final Applicant Guidebook. more

IGF Best Practice Forums, an Opportunity to Bring Your Experience to the Policy Debate

In the run-up to the 14th Internet Governance Forum in Berlin, Germany, 25 to 29 November, different groups are discussing best practices pertaining to specific internet governance policy questions. These groups are open and thrive on your input and experiences. Their findings will be presented at the IGF and published shortly after. The IGF Best Practice Forums intend to inform internet governance policy debates by drawing on the immense and diverse range of experience and expertise... 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

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

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
