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

Weekend Reads 033018: Olympic Destroyer, SONiC, and all the rest

The crippling Olympic Destroyer attack that hit several systems supporting the Pyeongchang Winter Olympics last month may have forever changed the game of attack attribution: the sophisticated attackers created a convincing forgery of malware associated with the North Korean nation-state Lazarus Group, fooling several experts who initially pinned the blame for the attacks on the DPRK. —Kelly Jackson Higgins @Dark Reading

SONiC is the default switch OS powering Azure and many other parts of the Microsoft Cloud. Since last year’s Summit, we have grown its footprint substantially and are now also powering services such as our AI platform, making sure researches have the very best experience when working on solving some of the world’s most pressing problems. —Yousef Khalidi @Azure

For decades, academics and technologists have sparred with the government over access to crypographic technology. In the 1970s, when crypto started to become an academic discipline, the NSA was worried, fearing that they’d lose the ability to read other countries’ traffic. And they acted. For example, they exerted pressure to weaken DES. —Steve Bellovin @CircleID

Cybersecurity attacks have become a weekly occurrence in many news columns. One recent example was that of one of our customers, QIWI payment system, successfully Continue reading

Juma Baldeh: Breaking Barriers to Access in Gambia

How do you shift the cultural stigma around technology and gender? As Juma Baldeh has proven in Gambia, you do it one girl at a time. Baldeh founded Hackathon Girls Banjul for girls ages 8 to 18 in her home country, in coordination with the Mozilla Foundation. As the first technology club of its kind there, members receive six months of free weekly classes on web literacy and basic computing skills. More importantly, the club gives more than 40 girls a safe space to collaborate and share experiences as they work together on projects for a tech-savvy Gambia.

“Too often I witness young girls, who are skilled in math and science, lose hope as they prepare for interviews and professional positions,” Baldeh said. “Right now, many girls in this field leave it because they think computer jobs are too difficult and they lose confidence at some point.”

The club started with a small space and just five girls, training to be proficient in basic computing skills, computer programing, online security and privacy, and research and networking. Through these skills the girls can then go on to civic participation, economic empowerment, and leadership roles. One of the many problems with Continue reading
