Routing Attacks on Internet Services

This post was co-authored by Yixin Sun, Annie Edmundson, Henry Birge-Lee, Jennifer Rexford, and Prateek Mittal. In this post, we discuss a recent thread of research that highlights the insecurity of Internet services due to the underlying insecurity of Internet routing. We hope that this thread facilitates important dialog in the networking, security, and Internet policy communities to drive change and adoption of secure mechanisms for Internet routing. more

Government Hacking: Proposed Law in the Netherlands

In 2012 I wrote a blog on CircleID called State hacking: Do's and don'ts, pros and cons. In this post I give some thoughts to the concept of a government "hacking back" at criminals. The reason for this was an announcement by the Dutch government that it contemplated law along these lines. The proposed law is now here: the Act Computer Criminality III. more

DOJ to Cruz: .Com Price Freeze Can Be Extended to 2024

On August 31st the Department of Justice (DOJ) sent a response to the August 12th letter from Senator Ted Cruz and some Congressional colleagues to the head of the Antitrust Division. In that letter Cruz et al asserted that if the pending extension of the .Com registry Agreement (RA) was granted in combination with the consummation of the IANA transition, that DOJ could be prevented from having "meaningful input into the prices that Verisign charges for registering a domain name within the .com domain for an extended period". more

Digital Governance Discussion Group (DGDG): One World, One Internet, Many Voices

On February 12–13, 2024, the first round of the final consultations for a Global Digital Compact (GDC) took place online and offline at the UN Headquarters in New York City. Around 50 governments and 50 speakers from non-governmental institutions took the floor. It was not really a dialog; it was a formal presentation of three-minute statements. more

Bypassing Geo-Locked BYOD Applications

In the wake of increasingly lenient bring your own device (BYOD) policies within large corporations, there's been a growing emphasis upon restricting access to business applications (and data) to specific geographic locations. Over the last 18 months more than a dozen start-ups in North America alone have sprung up seeking to offer novel security solutions in this space - essentially looking to provide mechanisms for locking application usage to a specific location or distance from an office, and ensuring that key data or functionality becomes inaccessible outside these prescribed zones. more

2008 Report Analyzing Distribution and Trends of IP Address Allocation

The study report analyzes the distribution and the trends of IP address allocation in 238 countries for 2007. From the data analysis (see Table 1 & Chart 1), the United States tops the allocation list by holding 37.73% of the IP addresses worldwide. It follows by United Kingdom (12.83%), Japan (7.64%), China (5.74%), Germany (3.81%), France (3.65%), Canada (2.81%), Korea (2.74%), Netherlands (2.00%) and Italy (1.67%). These Top 11 countries in the list occupied more than 80% of total allocated IP address ranges in the world in 2007. more

A Tipping Point for the Internet: 10 Predictions for 2018

The year 2018 represents a tipping point for the Internet and its governance. Internet governance risks being consumed by inertia. Policy decisions are needed if we want to prevent the Internet from fragmenting into numerous national and commercial Internet(s). Geopolitical shifts, in particular, will affect how the Internet is governed. The Internet is made vulnerable by the fragmentation of global society, which is likely to accelerate in response to the ongoing crisis of multilateralism. more

Who Cares About 50,000 .CAT’s?

This past May 19th, 5 years after its sunrise, puntCAT arrived at the 50,000 domain names landmark. We know that, nowadays, 50,000 domain names may hardly be described as shocking news, and, certainly, this is not our limit, and we believe there's still plenty of room for .cat to grow. Then, who and why should care about this number? more

Designing Secure Networks with Cisco Technology, Part 1

In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies.... "Wisdom consists in being able to distinguish among dangers and make a choice of the least harmful." That quote is quite possibly the most accurate depiction possible of the never-ending struggle between network security and corporate budget. Providing a mechanism to defend the enterprise network from every conceivable threat is impossible in terms of both technology and funding. more

Spam from Mobile Networks? Who Woulda Thought…

Mobile networks aren't usually thought of as sources of spam, but a quick look at some of the resources that track spam reveals they actually are. This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren't known to be sources of spam (at least not yet). What's really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it's permissible, are the culprits more

The ITU Busan Plenipotentiary

The ongoing ITU Plenipotentiary Conference in Busan South Korea is the quadrennial gathering where its Nation State Members gather to elect new leadership of its four permanent secretariats and populate a few other of its assorted bodies. The next two weeks are spent in endless sessions where several regional blocs of Members still enamored with pre-liberalization telecom models complain about the new world of telecommunications that they did not invent -- while engaging in copious use of their new smart phones and online services. more

A Recap of the 36th ICANN Conference in Seoul, Korea

The recently completed ICANN Conference in Seoul, Korea will be remembered for a unique accomplishment -- the first definitive step towards the addition of Internationalized Domain Names (IDNs) to the Internet root... As the announcement states, the applicants, at this time, are limited to nations and territories; the first IDNs will be in country code top level domains (ccTLDs). The generic TLDs, (the gTLDs, e.g., .org, .com and .info) will have to wait for their opportunity to apply for IDNs... more

Leading a Horse to Water

It is one thing to bring broadband internet to the masses, but how do we make them drink from the fountain of knowledge? One of the challenges, of course, is that the industry has not yet sold turn-key applications that capture the imaginations of the unconnected. Surprising as it seems, email, Facebook, file swapping and web surfing have not yet attracted 100% of the population. Are there some applications that might lend themselves to a toll-free model in order to reach the rest of the market? more

Ten Years of UDRP

In 1999, the Internet Corporation for Assigned Names and Numbers (ICANN) developed a policy to resolve disputes between trademark owners and registrants of domain names. This policy, the Uniform Domain-Name Dispute Resolution Policy (UDRP) was made available for disputes concerning an alleged abusive registration of a domain name. In the past 10 years alone, more than 16,000 disputes have been filed resulting in more than 10,000 domain name transfers. more

“Restoring” Internet Freedom for Whom?

Recently, a colleague in the Bellisario College of Communications asked me who gets a freedom boost from the FCC's upcoming dismantling of network neutrality safeguards. He noted that Chairman Pai made sure that the title of the FCC's Notice of Proposed Rulemaking is: Restoring Internet Freedom. My colleague wanted to know whose freedom the FCC previously subverted and how removing consumer safeguards promotes freedom. more
