Software opens up new career opportunities for network professionals

The topic of network engineer re-skilling has been front and center for the past few years. Some network professionals have embraced the concept and are leading the network industry in a whole new direction. Others, though, are more resistant and show about as much enthusiasm for this new world as my wife does when I ask her to watch a Star Trek marathon with me.Network professionals need to become software-fluent Part of the resistance to re-skilling is that change is scary and often hard. Many network engineers have been working a certain way for years, possibly decades, and now they are asking, "Do I need to throw those skills away and learn new ones?" To those people, I say an emphatic YES! It’s absolutely critical to learn new skills today, or you could find yourself quickly looking for a job.To read this article in full, please click here

Security Research is Critical to Protect the Open Internet

On, April 10, 2018 I joined over fifty like-minded individuals signing a letter emphasizing the importance of security research. The letter renounces a number of recent lawsuits, such as Keeper v. Goodlin and River City Media v. Kromtech, against security researchers and journalists and highlights the importance of the work they are doing to defend against a rapidly increasing number of security threats.

Security research, sometimes called white-hat hacking, is a practice by ethical hackers whereby they legally find flaws in information systems and report them to the creators of those systems. The ability to find and report these vulnerabilities before other bad actors can manipulate them has become increasingly important, especially in the context of the Internet of Things (IoT).

As we discussed at Enhancing IoT Security in Ottawa, Canada this week, Internet-connected devices offer great promise, but they can also create a host of security issues. It is crucial that we continue to encourage individuals to seek out and correct flaws in these devices as their application and use grows.

As Olaf Kolkman, Chief Internet Technology Officer at the Internet Society, wrote recently, security researchers are helping to make the Internet more secure. Collaboration between those Continue reading

What is hybrid cloud really, and what’s the best strategy?

Ask a group of IT leaders to define what a hybrid cloud is, and their answers are likely to be as diverse as the companies they work for. Once a black-and-white definition describing organizations with a mix of apps that reside in both the public cloud and in enterprise data centers, a hybrid cloud has now become much more complicated as the number of apps used in the enterprise grows and their integration requirements mount.  The average company uses more than 1,400 cloud services, according to Skyhigh Networks, often because lines of business are being pressured to innovate, leaving little time to develop a strategy for the most efficient and cost-effective way to run them.To read this article in full, please click here

Understanding Virtual Private Networks [and why VPNs are important to SD-WAN]

Video: Automatic Diagramming with PowerNSX

Here's a trick question: how often do your Visio diagrams match what's really implemented in your network?

Wouldn't it be great to be able to create or modify them on-the-fly based on what's really configured in the network? That's exactly what Anthony Burke demonstrated in the PowerNSX part of PowerShell for Networking Engineers webinar (source code).

You’ll need at least free ipSpace.net subscription to watch the video.

Review: Lenovo ThinkPad X1 Carbon

As part of the transition into my new role at Heptio (see here for more information), I had to select a new corporate laptop. Given that my last attempt at running Linux full-time was thwarted due primarily to work-specific collaboration issues that would no longer apply (see here), and given that other members of my team (the Field Engineering team) are also running Linux full-time, I thought I’d give it another go. Accordingly, I’ve started working on a Lenovo ThinkPad X1 Carbon (5th generation). Here are my thoughts on this laptop.

This is now my second non-Apple laptop in the last year. My previous non-Apple laptop, a Dell Latitude E7370, was a pretty decent laptop (see my review). As good as the E7370 was, though, the X1 Carbon is better.

The X1 Carbon features a dual-core i7 7500U CPU, which (subjectively, anyway) outperforms the mobile CPU in the E7370. This makes the X1 Carbon feel quite snappy and responsive. CPU performance was an issue for me with the Dell—it didn’t take much to tax that mobile CPU. I haven’t seen that issue so far with the X1 Carbon. Coupled with 16GB of RAM, the X1 Carbon is no Continue reading

NetDevOpEd: Open source principles give the workplace soul

If you’ve been tuning into Cumulus content lately, you probably know all about our initiative to bring S.O.U.L (Simple, Open, Untethered Linux) into networking — and for the uninitiated, feel free to check out our S.O.U.L page to learn all about the movement! It’s clear that our company and technology have S.O.U.L, but what does that look like in the office? Anyone who’s spent time at our office, in our bootcamps, with our people, etc. can feel that Cumulus Networks has “soul,” and this time we’re not talking about the acronym. We’ve got a passion, substance, life and feeling that pulses throughout our space like a funky bass line.

How do I know this? Well, I work at Cumulus, but it’s more than that. My former employers (before I started working at Cumulus Networks) are pretty varied, ranging from a restaurant to a university, but all of those jobs had one thing in common — they had no soul. To these Pink Floyd-ian businesses, employees were just cogs in the machine meant to forfeit passion for profit. Each day I dragged myself out of bed, drudged Continue reading

Successful First Event in the Canadian Multistakeholder Process – Enhancing IoT Security Series

On April 4, 2018, over 80 individuals met in Ottawa and virtually via livestream for the first event in the Canadian Multistakeholder Process – Enhancing IoT Security series. Participants represented a wide-range of stakeholder groups, including government, academia, public interest, and industry representatives. Two Internet Society Organization Members, the Canadian Internet Registration Authority and CANARIE, as well as Innovation, Science and Economic Development Canada and the Canadian Internet Policy and Public Interest Clinic were partners for this event. IoT security is a complex issue that requires all stakeholders to cooperate and participate in the development of solutions, and we were pleased to have such truly multistakeholder representation.

The event kicked off with an interactive presentation from Larry Strickling, Executive Director of the Collaborative Governance Project. Strickling provided an overview of the multistakeholder process and facilitated a discussion among participants to determine ground rules and define what constitutes consensus. Participants, both those remote and in person, outlined over a dozen rules and three key metrics for determining consensus, which will be used throughout the entirety of the project.

In the morning, participants heard from a series of speakers who presented on IoT security and risk, the balance between IoT’s technological Continue reading

Too Big To Fail is More Likely to Fail ?

People think that big companies are too big to fail and thats why you should buy from big companies.  Except that this is no longer true. To whit: HPE just divested all of its software assets. While HPE maintains a substantial interest in the new owner, I’m confident that HPE will walk away from those […]
