We Need a Common Language for the Internet of Things

When someone tells me they have bought smart light bulbs, an Internet-connected pet cam, or any other Internet of Things (IoT) device, I always get an unsettled feeling in the pit of my stomach. They’re so excited about the affordances or their new IoT devices and apps, but I am skeptical about the privacy and security vulnerabilities. How do I have a conversation about these concerns without coming across as hyper paranoid? Perhaps the answer is that we aren’t quite ready to discuss these issues on a societal level.

Privacy and security advocates all over the world have been talking about the threats that IoT may pose to society – unless standards and regulations are put in place to help mitigate some of these risks. They champion that privacy and security should be built into design and should not come as an afterthought.

While I praise the work that advocates are doing, IoT devices are on the shelves right now and we need to be able to have conversations with everyday folk about what privacy and security risks look like in the digital economy. However, how can we have these conversations when we haven’t yet established understandable and common terms Continue reading

A Review of Ubiquiti Wireless

About six months ago, I got fed up with my Meraki MR34 APs. They ran just fine, but they needed attention. They needed licenses. They needed me to pay for a dashboard I used rarely but yet had to keep up yearly. And that dashboard had most of the “advanced” features hidden away under lock and key. I was beyond frustrated. I happen to be at the Wireless LAN Professionals Conference (WLPC) and ran into Darrell DeRosia (@Darrell_DeRosia) about my plight. His response was pretty simple:

“Dude, you should check out Ubiquiti.”

Now, my understanding of Ubiquiti up to that point was practically nothing. I knew they sold into the SMB side of the market. They weren’t “enterprise grade” like Cisco or Aruba or even Meraki. I didn’t even know the specs on their APs. After a conversation with Darrell and some of the fine folks at Ubiquiti, I replaced my MR34s with a UniFI AP-AC-HD and an AP-AC-InWall-Pro. I also installed one of their UniFi Security Gateways to upgrade my existing Linksys connection device.

You may recall my issue with redundancy and my cable modem battery when I tried to install the UniFi Security Gateway for Continue reading

IDG Contributor Network: 5 reasons why it’s important to mix and match in your cloud strategy

The rise of the cloud settled the age-old debate about whether IT teams should choose an array of exceptional technologies from various providers, or a fully integrated stack of (mostly unexceptional) applications from a single vendor.Thanks to cloud computing, you can have the very best applications—and the very best clouds—for the IT tasks at hand. And you don't have to deal with the headache of investing heavily in infrastructure and building it yourself.Here's a quick look at five ways the cloud and related technologies enable your IT team to launch, integrate, scale, and secure the full spectrum of applications.1. You can pick the best cloud for the job While businesses may end up running most applications in a single cloud, there are lots of reasons to diversify and adopt a multi-cloud strategy. The major cloud infrastructure providers have individual strengths—and a well-planned multi-cloud strategy enables you to pick the cloud platform that offers the best combination of technical features, pricing, and performance for each application. Some examples of workloads that may be better running on one hyper-scale cloud over another could be enterprise business applications, big data or high-performance computing (HPC) workloads.To read this article Continue reading

IDG Contributor Network: 5 reasons why it’s important to mix and match in your cloud strategy

IDG Contributor Network: Visibility is key for devops and the hybrid cloud

Cloud has undoubtedly become a key component of successful business in recent years, especially when you consider the race to digitally transform. Across the globe, companies are moving their applications and services to the cloud and are consequently reaping the benefits of lower capex and opex as a result.However, with this process, cloud migration is only a beginning for any organization’s digital transformation (DX) journey. If harnessed correctly, cloud is a pillar of innovation for DX, and can be a driving force for new business models and use cases that – even a few years ago – weren’t possible. No one knows this better than devops teams; these teams hold the line when it comes to continuous delivery and deployment, and it therefore stands to reason that devops play a crucial role in the digital transformation journey. In practice however, the decision makers in charge of cloud strategies are rarely those in the bowels of the ship.To read this article in full, please click here

When Testing, Get Active

When troubleshooting application performance issues, ping alone may not detect the problem. That’s where active testing can help.

Worth Reading: IPv6 Renumbering == Pain in the …

Johannes Weber was forced to stress-test the IPv6 networks are easy to renumber nonsense and documented his test results – a must-read for everyone deploying IPv6.

He found out that renumbering IPv6 in his lab required almost four times as many changes as renumbering (outside) IPv4 in the same lab.

My cynical take on that experience: “Now that you’ve documented everything that needs to be changed, make sure it’s automated the next time ;)”

Let’s talk about lasers! In this episode of Kernel of Truth, I asked Product Manager Brian O’Sullivan (who you’ll remember from our episode about automation) and Principal Engineer Scott Emery to join me in the recording booth and chat about optical networking. We’ll get into topics like forward error correction, the divide between data center networking engineers and optical networking engineers, Voyager and Pink Floyd. Who knew that progressive rock had anything to do with optical networking?? (It doesn’t, really, but we somehow worked it in.)

So tune in and learn why an open packet optical platform is so innovative for optical networking and telco! And make sure to subscribe to the Kernel of Truth podcast so you stay up to date on the open networking revolution â€” get with the future of networking so you’re not just “Another Brick in the Wall!”

ETSI Releases Security Encryption Specs for 5G and IoT Uses

The specifications are for attribute-based encryption that describes how to secure personal data, combining access control with data encryption.

BrandPost: Ethernet Adventures: Making Progress with an Old Friend – Good ol’ Ethernet

In the second post of this 3-part series we unravel one hero’s journey on the road to streamlined enterprise networking operations. Ciena’s Chris Sweetapple follows Our Hero’s adventures as he realizes the opportunities of high-bandwidth business Ethernet.In episode 1 our hero, stuck in a tangle of outdated networking equipment, services and complexity, realizes that with business Ethernet as his WAN technology of choice, he can complement the existing network set-up and connect his branch offices, while handling massive volumes of traffic concurrently using high speed (up to 100G) high-performance Ethernet connectivity.To read this article in full, please click here
