Reported Cyberattack Against Israel Only Ransomware to Regulatory Body, Electric Grid Not In Danger

Ransomware via a phishing attack was sent to Israel Electric Authority, not the power grid, as was heavily reported in mainstream media today. According to a cyber analyst in Israel (Eyal Sela) the media reporting so far is misleading with regards to the context around the incident, reports Robert M. Lee of SANS Institute. more

Busting 3 Popular and Misleading Terms in Telecom

"Philosophy is a battle against the bewitchment of our intelligence by means of our language." (-Ludwig Wittgenstein) The words we use to describe telecoms networks often contain hidden metaphors and meanings that lead us into wrong thinking. Here are three examples... Why misleading? The word "best" implies both benevolent and optimal intentionality: the network is going to do the "right" thing for its users, and it will maximise the "rightness" in some way. more

Are Telcos Becoming Slum Landlords?

In the 1950s and 60s, large numbers of immigrants came to London from the Caribbean and other Commonwealth countries. They had few resources, yet needed somewhere to live. Many fell prey to exploitative landlords. These unscrupulous rentiers packed tenants into formerly swanky parts of town, which then became slums. This process even birthed a new word in British English - "Rachmanism" - to define the archetypal unethical treatment as practised by one notorious landlord. more

Who Will Secure the Internet of Things?

Over the past several months, CITP-affiliated Ph.D. student Sarthak Grover and fellow Roya Ensafi been investigating various security and privacy vulnerabilities of Internet of Things (IoT) devices in the home network, to get a better sense of the current state of smart devices that many consumers have begun to install in their homes. To explore this question, we purchased a collection of popular IoT devices, connected them to a laboratory network at CITP, and monitored the traffic that these devices exchanged with the public Internet. more

Which Way Does Your Data Flow?

Data may be moving to the cloud, but understanding the physical geography underlying the cloud is becoming increasingly critical. October's decision by the European Court of Justice, striking down key portions of the Safe Harbor rules that some companies had relied on to legally transfer personal data between Europe and the U.S., was only the latest example of the regulatory uncertainty involved in cross-border data flows. While Internet companies have begun to address challenges at the static geographic points where data is resident, understanding the actual paths that data travels is an important and sometimes overlooked part of the compliance analysis. more

Performance Test White Paper for SDN Controller Issued

Recently, BII-Global SDN Certified Testing Center (SDNCTC EN | CH) issued the Performance Test White Paper for SDN Controller (hereinafter Whitepaper) at China Future Network and Development Innovation Forum, which truly fills the vacuum in SDN controller performance testing at home. It, by means of elaborate results from the open-source controller tests, provides reliable analysis report to all corners within the industry, which has been highly thought of and widely supported by experts both at home and broad. more

The Appeal Against Broadband Reclassification

A British perspective on a very American process... As a new member of the the "Tech Elders", I was invited to join yesterday's hearing in Washington, DC on the reclassification of broadband Internet access services. The US Federal Communications Commission (FCC) has decreed that Internet access should switch from being lightly regulated as an 'information service' (Title I) to a more heavily regulated as 'telecommunications service' (Title II). I'd first like to say that the process and content was a credit to the rule of law in the United States. more

Audio and Video Traffic Passes 70% in North America

Real-Time Entertainment (streaming video and audio) traffic is now responsible for over 70% of North American downstream traffic in the peak evening hours on fixed access networks, according to a new report from Sandvine. Five years ago, video and audio streaming accounted for less than 35%. more

WSIS+10 and the Challenge of Securing the Internet

In just one week, representatives of governments from all around the world will gather at the UN headquarters in New York for the 10-year Review of the World Summit on the Information Society, a.k.a. "WSIS+10". We are very pleased to see the consensus forming that the principles of multi-stakeholder cooperation and engagement should be at the core of the Information Society. Moreover, consensus has emerged around a "post-2015" vision for how the Internet can be used to support the Sustainable Development Goals (SDGs) that will bring about a better future for us all. more

In Network Security Design, It’s About the Users

One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more

Zero Rating, a Poisoned Chalice for the Developing World

A very Interesting meeting The Internet Governance Forum (IGF) with an ambitious theme of connecting the worlds next billion people to the Internet took place in early November 2015 in a beautiful resort city of João Pessoa in Brazil under the auspice of the United Nations. Few citizens of the world paid attention to it yet the repercussions of the policy issues discussed affect us all. more

USA Fibre Investments Encouraging Further Operator Expansion

According to data from the FttH Council, the number of homes passed with fibre in the US increased 13% in 2015, year-on-year, to 26 million. Combined with Canada and Mexico, the number of passed homes has reached 34 million. The take-up rate is excellent by international standards, at more than 50%. Commonly operators look to about 20% to 30% take-up before work can begin on new fibre infrastructure to communities. more

How DANE Strengthens Security for TLS, S/SMIME and Other Applications

The Domain Name System (DNS) offers ways to significantly strengthen the security of Internet applications via a new protocol called the DNS-based Authentication of Named Entities (DANE). One problem it helps to solve is how to easily find keys for end users and systems in a secure and scalable manner. It can also help to address well-known vulnerabilities in the public Certification Authority (CA) model. Applications today need to trust a large number of global CAs. more

Did We Build the ‘Right’ Internet? (An Interview with Prof Andrew Russell)

The longer I have been in the tech industry, the more I have come to appreciate the hidden complexity and subtlety of its past. A book that caught my attention is 'Open Standards and the Digital Age' by Prof Andrew Russell of Stevens Institute of Technology in New Jersey. This important work shines a fresh light on the process that resulted in today's Internet. For me, it places the standard 'triumphant' narrative of the rise of TCP/IP into a more nuanced context. more

Telecoms Infrastructure As a Service

More than a decade ago we predicted that the telecoms industry would be transformed, driven by its own innovations and technological developments. As a result we indicated that in many situations the telecommunications infrastructure would be offered as a service by hardware providers. We also predicted that this would open the way for a better sharing of the infrastructure. more
