The Week in Internet News: IT Pros Know IoT Security Needs Work, But They Aren’t There Yet

What IoT security problem? Most IT professionals realize the Internet of things poses some security risks, but less than a third of them actively monitor for third-party IoT security problems, according to a survey detailed at ZDNet. More than a third of those surveyed said that nobody in their organization is responsible for reviewing the risk-management policies of their IoT vendors.

Some security risks, only faster: Meanwhile, the European Union Agency for Network and Information Security is warning organizations that 5G mobile service may bring the same security risks as earlier mobile standards have. Known flaws in SS7 and Diameter, the signaling protocols used in 2G, 3G, and 4G, could end up in 5G, and allow traffic to be eavesdropped or spoofed, reports ARN.

Community broadband for net neutrality: The American Civil Liberties Union is urging U.S. cities to build their own broadband networks as a way to protect net neutrality principles, now that the Federal Communications Commission has repealed its related regulations. The Hill has a story. Many small U.S. cities are already building their own, in an effort to provide faster or cheaper service than commercial providers, Governing Magazine says.

Welcoming Cisco to disaggregation

Earlier this week, Cisco announced that they will be offering a disaggregated solution with their Cisco IOS XR and Nexus operating systems (1). It’s true, the same organization that claimed to have killed white-box networking is jumping on the bandwagon three years later.

Open networking is no longer just the future

It’s now a requirement in today’s innovative data centers. Cumulus was founded on the notion that the future of data center networking is disaggregation, that the industry should be open and that innovation will only prevail when open networking does. The fact that one more incumbent vendor has acknowledged this notion about where the industry is headed only validates our vision. The future of networking truly is here, and we welcome Cisco to the club — really!

In the last few years, and even last several months, we’ve seen open networking takeoff. From the moment we helped bring ONIE to the market back in 2013, we knew things were going to change in the industry. Since then, we’ve seen the list of participating hardware vendors grow like crazy and our customer base grow with them. We’ve seen web-scale companies like Facebook, Google, LinkedIn and more contribute to the Continue reading

Security: Mitigating Spectre on Older Intel CPUs

I suspect all of my readers are well aware of the Spectre exploit affecting, among others, Intel CPUs going back many years. Intel for their part, after a few missteps, have issued microcode updates for more recent CPUs. But for those of us with computers running older CPUs, the solutions are less likely to be forthcoming. Thankfully there is a solution.

 

Branch Prediction and Speculative Execution

The Spectre exploit affects processors which perform branch prediction, a kind of optimistic lookahead where the processor prepares and executes a potential instruction before it is actually requested. For example, if the processor encounters conditional code (like and if..then..else construct), based on previous behavior it predicts what the most likely outcome is and thus which branch of code would be executed as a result, then loads and executes that code in advance (hence “speculative execution”). If the branch prediction is correct, then since the code was already executed the code will benefit from improved performance. Spectre abuses some predictable timing behavior of the speculative execution to be able to extract other processes’ data from the CPU caches. In other words, it’s bad news for security.

Wireless Thoughts From Aruba Atmosphere

I just got back from Aruba Atmosphere this week and I thought it would be a good chance to go over some of the cool stuff that I saw there.

• Rasa is now Aruba NetInsights. That platform is going to be a big one for Aruba in the future. There’s a lot of information that is being gleaned from installations and it’s fueling some hard looks at best practices and such. Also funny that it’s being installed primarily in university campuses to profile coverage and client capabilities. Those are usually pretty hostile environments for users and administrators alike.
• The security pieces that were shown off were also very interesting. The idea of port profiles has always made me a bit skeptical, but the way that Aruba is doing actual traffic profiling makes me think they have it this time. It’s also really cool that it can be done with non-managed devices in the middle. I think the key is that Aruba is doing actual traffic profiling instead of just looking at the basics behind the packets, like ports or VLANs. Real, automatic port security could be a huge win for places that need on-the-fly access to rapidly changing conditions. Like, Continue reading

Why Does Training Your Employees Matter?

In today’s competitive job market, many employers find themselves asking the question “How do I keep my employee’s satisfied?”

What’s the Secret to Retaining Top Talent?

We’ve all heard that the job market is changing. With millennial’s making up a third of the workforce and growing, according to Forbes Magazine, it’s becoming increasingly common for individuals to jump from job to job and even switch industries. In the midst of this change, many employers may wonder if training employees is a waste of time. Why would you want to spend valuable resources training someone who is just going to leave in a couple of years?

What if I were to tell you that the secret to keeping talent is fueling it, enabling your employees to learn and grow by providing them with training opportunities.

We’re Biologically Wired to Learn

As humans, we crave learning. It’s an innate survival instinct that despite our modern way of life still prevails. Whether you know it or not, your employees are already learning in the workplace every day. They’re learning about job skills, company policies and procedures, company values and colleagues, just to name a few. Why not extend this learning culture to Continue reading

Connecting 500K Bolivians to a National Research and Education Network

As players in the development of the Internet in the world, the academic and scientific communities of the five continents have made important efforts to establish National Research and Education Networks (NRENs) to interconnect universities and research centers to exchange information at a regional level. Examples of these networks are GÉANT in Europe, Internet 2 in the United States, and RedCLARA (Latin American Cooperation of Advanced Networks) in the Latin American region.

The Bolivian academic sector is made up of more than 60 universities with half a million students and 20,000 teachers. Unfortunately Bolivia is the only country that is not connected to RedCLARA. Bolivia not only lacks connection with any NREN, but also has not managed to constitute its own National Academic Scientific Network. Since 2002, several attempts have been made, involving more than 30 universities in the country. As a result, the statutes and regulations of the Bolivian Integration Academic Network (RIAB) have been drafted.

The project Red Academica Boliviana, led by the Internet Society Bolivia Chapter and supported by Beyond the Net Funding Programme, has a long-term goal: to lay the foundations that will strengthen the development of research and education in Bolivia through the Continue reading

SpaceX Gets US Approval to Launch Space-Based Broadband Service

If all goes as planned, Elon Musk’s SpaceX will eventually launch 4,425 satellites into orbit with the goal of delivering broadband service to all corners of the Earth.

The U.S. Federal Communications Commission, on Wednesday, approved SpaceX’s request to move forward with its space-based broadband proposal, on the condition that the aerospace company launch half of the satellites within six years.

Once deployed, the low-Earth orbit satellites will cover the entire United States, including Puerto Rico and the U.S. Virgin Islands, and eventually, provide “full-time coverage to virtually the entire planet,” the FCC said in its approval order.

SpaceX plans to begin launching the satellites in 2019. About 800 satellites will need to be deployed for the broadband service to be operational. The company, in the midst of launching 10 satellites on Friday, didn’t have an immediate comment on the FCC approval.

The company calls the proposed service “Starlink” and plans to offer wireless broadband speeds comparable to fiber-optic service.

The FCC imposed a number of conditions on SpaceX’s application. Several other satellite operators raised concerns about spectral interference from the SpaceX satellites, and others suggested the large number of satellites would eventually lead to orbital debris, or Continue reading
