Tips to improve IoT security on your network

Judging by all the media attention that The Internet of Things (or IoT) gets these days, you would think that the world was firmly in the grip of a physical and digital transformation. The truth, though, is that we all are still in the early days of the IoT.The analyst firm Gartner, for example, puts the number of Internet connected “things” at just 8.4 billion in 2017 – counting both consumer and business applications. That’s a big number, yes, but much smaller number than the “50 billion devices” or “hundreds of billions of devices” figures that get bandied about in the press.To read this article in full, please click here(Insider Story)

Video: What Is PowerNSX?

One of the beauties of VMware NSX is that it’s fully API-based – you can automate any aspect of it by writing a script (or using any of the network automation tools) that executes a series of well-defined (and well-documented) API calls.

To make that task even easier, VMware released PowerNSX, an open-source library of PowerShell commandlets that abstract the internal details of NSX API and give you an easy-to-use interface (assuming you use PowerShell as your automation tool).

AT&T’s dNOS Initiative Spotlights Fake News from Cisco (et al.)

network-serverOne thing that’s clear from recent events is that the “alternative” path for network infrastructure refresh and build-outs – disaggregation – has just become exciting again due, in part, to AT&T’s recent announcement of the company’s dNOS (disaggregated Networking Operating System) initiative. Actually, prior to this proposal the fact that Pica8 and Cumulus – the only two pure open-standards-based NOS vendors in the market – combined have close to 2,000 current customers running on common hardware suggests that it’s been pretty exciting for some time now.

But AT&T’s new proposal does present us with a perfect opportunity to finally throw a bright spotlight on the palette of Fake News that has been tossed around the industry about disaggregated networking solutions and white-box networking in general. Of course, the elephant in the networking room is always Cisco, so let’s start there to see why AT&T pushed out this proposal in the first place.

Over the years, Cisco has successfully stared down any real threats to its account-control-plus-per-hardware-port-revenue business model, building itself up to the hegemony that it has today and, in the process, inadvertently laying waste to its customers’ ability to innovate in their own market segments based on differentiated network services.

5 Ways you can leverage the Linux community for your data center network

Here at Cumulus, we often talk about the benefits of having an operating system on Linux (if you need to be re-schooled on the benefits of unifying the stack, head here). But something that possibly goes overlooked, or at least under appreciated, is the value of the Linux community itself. The community is made up of 50,000 or so engineers all passionate about learning, improving and creating code. People like to say that when you go with a Linux operating system, you’re “standing on the shoulder of giants,” meaning that you don’t only have to rely on your inhouse engineering team (even if they’re world-class engineers), but rather you’re relying on thousands of engineers, including some of the absolute best in the business. Since Cumulus Linux runs on Linux, our customers have this community at their disposal. So why does that really matter? Here are five reasons to consider.

1. Security

The most widely cited benefit of having a community of 50,000 behind you is security. Basically it looks something like this. Let’s say you’re with a proprietary vendor (*cough* Cisco *cough* Juniper *cough*), and there is a glitch in your latest package installation causing a security vulnerability. Maybe Continue reading

Aerohive’s Atom boldly goes where no Wi-Fi has gone before

The opening to “Star Trek: The Original Series” featured Captain Kirk proclaiming that space was the “Final Frontier” and that the Enterprise was going to “boldly go where no man has gone before.”In networking, Wi-Fi is really the final frontier, as it lets us explore strange new apps and seek out new tweets regardless of where we are. Untethered from cables, we are as free to roam around as the Enterprise was in space. There should be no question that good Wi-Fi is as important to us today as dilithium crystals were to the Enterprise.But what happens when Wi-Fi isn’t available? Or just as bad, when the connectivity is almost there but not quite strong enough to be useful. I recall being in a hotel where I couldn’t connect to Wi-Fi at the desk in the room, but I could connect if I sat in the hallway by the entry door, so I wound up sitting there all night trying to get work done.  It’s easy to say that Wi-Fi should be everywhere, but sometimes it’s hard to achieve that because of interference or cabling problems.To read this article in full, please click here

Different Server Workhorses For Different Workload Courses

Co-design is all the rage these days in systems design, where the hardware and software components of a system – whether it is aimed at compute, storage, or networking – are designed in tandem, not one after the other, and immediately affect how each aspect of a system are ultimate crafted. It is a smart idea that wrings the maximum amount of performance out of a system for very precise workloads.

The era of general purpose computing, which is on the wane, brought an ever-increasing amount of capacity to bear in the datacenter at an ever -lower cost, enabling an …

It’s launch day for Sylabs: Promoting portable high-performance containers for Linux

Today is launch day for Sylabs — a new company focused on promoting Singularity within the enterprise and high-performance computing (HPC) environments and on advancing the fields of artificial intelligence (AI), machine/deep learning, and advanced analytics.And while it's launch day for Sylabs, it's not launch day for the technology it will be promoting. Singularity has already made great strides for HPC and has given Linux itself more prominence in HPC as it has moved more deeply into the areas of scientific and enterprise computing. With its roots at Lawrence Berkeley National Laboratory (Berkeley Lab), Singularity is already providing a platform for a lot of heavy-duty scientific research and is expected to move into many other areas, such as machine learning, and may even change the way some difficult analytical problems are approached.To read this article in full, please click here

Researchers find malware samples that exploit Meltdown and Spectre

It was inevitable. Once Google published its findings for the Meltdown and Spectre vulnerabilities in CPUs, the bad guys used that as a roadmap to create their malware. And so far, researchers have found more than 130 malware samples designed to exploit Spectre and Meltdown.If there is any good news, it’s that the majority of the samples appear to be in the testing phase, according to antivirus testing firm AV-TEST, or are based on proof-of-concept software created by security researchers. Still, the number is rising fast.To read this article in full, please click here
