Extreme Networks’ short-term growing pains are no cause for worry

“It was the best of times, it was the worst of time” is the opening to the famous Charles Dickens book, A Tale of Two Cities. It's also described Extreme’s financial performance over the past year.Earlier this year the company stock was trading a hair over $15 per share. Today, after it came up light on its fiscal third-quarter financial results, the stock plunged over 25 percent in after-hours trading and now stands at $8.40, a little over half of its 52-week high. This could change when the market opens, depending on investor sentiment.[ Check out our hands-on reviews: 5 top hardware-based Wi-Fi test tools and Mojo wireless intrusion prevention system. ] Extreme is now the largest enterprise network pure play In actuality, saying it’s the worst of times is a bit overly dramatic, as a few years ago, most industry experts thought Extreme Networks was dying a slow death. In 2015, Ed Meyercord took over as CEO and he and the company's chief marketing, development and product operations officer, Norman Rice, embarked on a plan to acquire underappreciated assets from companies where networking wasn’t the primary business. Rolling up these assets would help Extreme get its Continue reading

IDG Contributor Network: 3 generations of secure SD-WAN services

You simply can’t take advantage of all that SD-WAN has to offer without giving branch offices local Internet access and you can’t give them local Internet access without securing them. SD-WAN for all its strengths does not provide robust edge security. Yes, data is encrypted in transit. And, yes, some SD-WAN appliances come with basic stateful firewalling capabilities. But with attacks coming at layer-7, branches require a next-generation firewall (NGFW) and updated IPS/IDS capabilities to protect locations —  not a basic firewall. For all intents and purposes, branch SD-WAN needs layer-7 security, which is why you see so many SD-WAN vendors striking partnerships with security vendors or some building security into their appliances.To read this article in full, please click here

History Of Networking – Geoff Houston – BGP Security

Recent history tells us that even after decades of pervasive use, BGP is far from a fully secure protocol. In this episode of History of Networking on Network Collective, Geoff Houston joins us to talk about how we got here and why previous attempts at BGP security have fallen by the wayside.

Datanauts 133: Perfecting The Job Hunt

Whether by choice or circumstance, it’s inevitable you’ll find yourself looking for a new job.

On today’s Datanauts episode we break down the job hunt process to help you understand what you want, what you have to offer, and how to make the most of your application.

Our guest is Doug Lane, a tech/ops professional who’s been working in IT for 25 years. He’s also recently gone through the process of finding and getting a new job.  You can follow him on Twitter at @debuggist.

Doug shares his experiences and tips about how he approached the job search. We start by talking about honestly understanding your own strengths and weaknesses, and then thinking about what kind of job it is you really want.

We also discuss how to evaluate job descriptions, and how to nail the application process.

Cavium launches ThunderX2 ARM-based server processors

Cavium this week announced general availability of ThunderX2, its second-generation 64-bit, ARM-based system-on-a-chip (SoC) line of server processors. And it’s coming with some big-name endorsements.The first generation, ThunderX, had a more muted launch two years ago. No one wanted to get on Intel’s bad side, it seemed, and Intel was viewing ARM, not AMD, as its biggest threat. Fast forward two years, and Cavium has endorsements from HPE, Cray, and Atos, as well as HPC users such as Sandia National Labs and the U.K.’s GW4 Isambard project.Cavium announced ThunderX2 almost two years ago. It’s not an upgrade to ThunderX; it’s a whole new chip. It acquired a line of ARM server processors code-named Vulcan from Broadcom after the company was acquired by Avago and decided to shed its data center effort.To read this article in full, please click here

DNA Tests Raise Privacy Questions

The news was amazing: Police in California used DNA evidence collected decades ago to identify the suspected Golden State Killer, a serial killer and rapist active between the mid-‘70s and mid-‘80s.
Investigators from the Sacramento County Sheriff’s Department entered the old DNA into online genealogical database GEDmatch and were able to zero in on suspect Joseph James DeAngelo Jr. by linking the DNA sample to relatives in the database.

A suspected serial killer won’t generate much sympathy from the public, but privacy advocates say the case raises a series of difficult questions about uses of DNA.

The Golden State Killer “was absolutely evil,” said Pam Dixon, executive director of the World Privacy Forum. “We can all definitely agree that serial killers should be taken off the street.”

Still, Dixon and other privacy advocates wonder about the repercussions of the case. “There is no privacy right that I know of in regard to this kind of linking,” she said.

Among the major questions:

  • What court approvals should police get before searching DNA databases?
  • Should police be able to use DNA from distant relatives to track down criminals?
  • And how long should DNA evidence be searchable?

These are difficult questions, but Continue reading

IDG Contributor Network: IoT sensors, advanced ESRI mapping and Alexa warn residents of impending floods

Scott Pruitt, EPA Administrator’s assertion that “global warming might be beneficial” may be reassuring to some, but others living close to the coast prefer the safety of an early warning when they might be flooded from rising sea levels.Predicting floods from storm surges, rain, hurricanes and tides over miles of coastline is hard. How do your monitor water levels over such a broad area? How can floods be predicted with these data streams? How can thousands of people be alerted?  The Virginia Institute of Marine Science (VIMS) is pioneering an innovative approach that combines IoT sensors, advanced mapping and Alexa.To read this article in full, please click here

IDG Contributor Network: 7 common cloud data management pitfalls to avoid

There are many compelling reasons to migrate applications and workloads to the cloud, from scalability to easy maintenance, but moving data is never without risk. When IT systems or applications go down it can prove incredibly costly for businesses. A single hour of downtime costs over $100,000 according to 98% of organizations surveyed by ITIC.Mistakes are easy to make in the rush to compete. There’s a lot that can go wrong, particularly if you don’t plan properly.“Through 2022, at least 95% of cloud security failures will be the customer’s fault,” says Jay Heiser, research vice president at Gartner.To read this article in full, please click here
