Can Mobile Operators Afford a Mobile-Only Strategy?

With 4G rollouts in many developed mobile markets reaching completion, it might be time to check the balance of the state of the mobile industry. Looking at campaigns around the world it is clear that what you see are 'me too' strategies. The advertising campaigns and the marketing hyperbole around them might suggest that a particular operator has now done something unique or very special, but if one looks beyond the advertising blurb it is clear that the campaign is nothing new and/or that what is on offer can be very easily matched by their competitors in the market. more

In a Networked World Knowing the Right Time Is Essential but How Accurate Are the Computer Clocks?

Computers have always had clocks. Well maybe not clocks as you might think, but digital computers have always had oscillators, and if you hook the oscillator to a simple counter then you have a clock. The clock is not just there to tell the time, although it can do that, nor is it there just to record the time when data files are created or modified, though it does that too. Knowing the time is important to many functions, and one of those is security. more

Do-It-Yourself Rural Fiber

Necessity has led Cubans to become do-it yourself (DIY) inventors -- keeping old cars running, building strange, motorized bicycles, etc. They've also created DIY information technology like software, El Paquete Semanal, street nets and WiFi hotspot workarounds. Last June the International Telecommunication Union (ITU) adopted a standard for "low-cost sustainable telecommunications infrastructure for rural communications in developing countries," L.1700. L.1700 cable should be of interest to both DIY technologists and ETECSA. more

Over 50 Internet Shutdowns Reported in 2016

"Governments around the world shut down the internet more than 50 times in 2016 -- suppressing elections, slowing economies and limiting free speech," Lyndal Rowlands reporting in IPS. more

Canadian Telcos Fast Tracking FttH to Combat Cable Operators

There are a number of stimuli which are pushing Canada's burgeoning FttH market, and the government and telcos alike have made significant steps to improve the reach and capacity of broadband infrastructure. These measures will show real benefits for consumers in recent years. From the government's side, its Economic Action Plan, launched in 2009 as a response to the global financial crisis, included a pledge to provide $225 million over three years towards its Broadband Canada Program, geared to extending broadband coverage to underserved communities. more

M2M Hype and Reality

There are many predictions that the next big wave in telecoms is M2M and that this will be the next growth market for the telecoms industry. There is no doubt that M2M is a revolutionary development, but we need to separate the hype from the reality. In order to do this it is best to divide the major developments into two main areas, although there is no doubt that others will emerge over time. One area is the sensors that are being installed in networks such as electricity, the environment, roads and other infrastructure. more

Know Someone Who Has Made the Internet Better? Postel Service Award Nominations Deadline May 15

Do you know of someone who has made the Internet better in some way who deserves more recognition? Maybe someone who has helped extend Internet access to a large region? Or wrote widely-used programs that make the Internet more secure? Or maybe someone who has been actively working for open standards and open processes for the Internet? more

UN Broadband Commission 2.0

Back in late 2009 I had the honour of explaining my views on how broadband can deliver social and economic benefits to countries and their people to Dr Hamadoun Touré the Secretary-General (SG) of the ITU, the UN body looking after global telecoms. He showed a particular interest in the initiative Australia had taken in developing the NBN. This discussion with the SG led to the establishment in 2010 of the UN Broadband Commission, co-sponsored by UNESCO and the ITU. Dr Touré invited 50 Commissioners from around the world to participate in this initiative, half of them from private industry. more

Threat Intelligence in Latter 2019: Overcoming the Same and New Challenges

Does threat intelligence (TI) work? I looked into that question last year, exploring the reasons why it actually doesn't and what can be done to remediate the situation. Since then, more companies have incorporated TI into their security processes, and many are still not getting the benefits they expect. What's causing the dissatisfaction? Interestingly, pretty much the same aspects... more

Some Observations on Reachability of Egyptian Networks and Providers

Different media are reporting that Internet and other forms of electronic communications are being disrupted in Egypt. Presumably after a government order in response to the protests. Looking at BGP data we can confirm that according to our analysis 88% of the ‘Egyptian Internet’ has fallen of the Internet. In this post I’ll share some observations I made with regards to the reachability of Egyptian networks and providers. more

Study Finds IPv6 Adoption Exposes More Residential Devices to Unsolicited Traffic

As IPv6 adoption accelerates, a new study warns that the disappearance of NAT in home networks is exposing millions of devices to online threats -- potentially fueling a new wave of powerful IoT botnets. more

The Lean and Antifragile Data Centre

Cloud is a new technology domain, and data centre engineering is still a developing discipline. I have interviewed a top expert in cloud infrastructure, Pete Cladingbowl. He has a vision of the 'lean' data centre and a better kind of Internet for users to reach it. He also has a roadmap for how these can be practically realised. The key is to apply established theories of value flow from more mature industries. more

The Christmas Goat and IPv6 (Year 11)

This is the fourth year now with almost no snow during the Christmas Goat event here in Sweden, and so once again, you get a photo without any snow. Because of Covid-19 and 99.99% people working for home, I have not even seen the Goat live this year... What a crazy year it has been! more

Can We Really Blame DNSSEC for Larger-Volume DDoS attacks?

In its security bulletin, Akamai's Security Intelligence Response Team (SIRT) reported on abuse of DNS Security Extensions (DNSSEC) when mounting a volumetric reflection-amplification attack. This is not news, but I'll use this opportunity to talk a bit about whether there is a trade-off between the increased security provided by DNSSEC and increased size of DNS responses that can be leveraged by the attackers. more

Pentagon Reveals Largest Ever Loss of Defense Data in Cyberattack

The Associated Press published an article today that the Pentagon revealed that earlier this year, they suffered one of its largest ever loss of sensitive data to a foreign government by a cyberattack. ... It's hard to say what's right and what's wrong. On the one hand, the Secretary of Defense says that the cyberwar is very real. On the other hand, the cyberczar Howard Schmidt said that there is no cyberwar and instead government needs to focus its efforts to fight online crime and espionage... more
