Security keeps getting more complex, and despite a multitude of products, tools and processes, organizations find it challenging to prevent 100 percent of breaches or unwanted access. Zero Trust holds the promise of achieving tighter security by only trusting network traffic that is specifically permitted by a security policy. While the task appears daunting, those organizations that follow a step-by-step approach can achieve success.
The process followed by VMware IT (VMIT) can serve as a blueprint for other organizations, removing some of the mystery and complexity. VMIT embarked on a Zero Trust project for data center security to prevent unwanted lateral movement, restricting communication among workloads to only the minimum needed to complete their jobs. The goal was to make Zero Trust the new normal for all applications in the data center. To do so, the team needed to gain a complete understanding of all applications, down to the workload level. Once understood, effective policies can be crafted to permit only the desired behavior.
Step one: macro-segmentation
Achieving Zero Trust fits neatly into a five-step approach (see A Practical Path to Zero Trust in the Data Center white paper), which starts with macro-segmenting the network and culminates in micro-segmenting all Continue reading
The post The new NFA v 21.06 has arrived. You asked, we listened. appeared first on Noction.
We compared Zoom, Microsoft Teams, Cisco Webex, Google Meet, BlueJeans, and GoToMeeting in real-world tests to see which videoconferencing platforms perform best for business users. Here’s how they stack up.
It’s time for another this is what we did in the last six months blog post. Instead of writing another wall-of-text, I just updated the one I published in early January. Here are the highlights:
That’s about it for the first half of 2021. I’ll be back in early September.

Hello my friend,
In the previous blogpost we’ve introduced the Batfish and how to set it up. Today we’ll take a look how to perform the analysis of the configuration to figure out discrepancies, which may lead to broken operation of your network.

In software development we have a concept called CI/CD (Continuous Integration/Continuous Delivery). In a nutshell, it’s a methodology, which incorporates mandatory testing of configuration (code, software version, etc) before bringing it to production. The main idea behind it is that automated testing and validation will make sure that code is stable and fit for purpose. Automated testing? That’s where the automation comes to the stage.
And automation is something what we are experts in. And you can benefit from that expertise as well.
In our network automation training we follow zero to hero approach, where we start with the basics including Linux operation and administration topped with Continue reading
This is the story of studying Kubernetes basics from the perspective of network engineer. I had basic Linux background, some free time, and willingness to discover this brave new world of containers, pods and microservices.
I think one of the best ways to do this kind of studying is to follow the blueprint of recognized industry certification. This gives you a concrete study plan and bring structure to your knowledge from the very beginning.
There are such certifications in Kubernetes world – CKA and CKAD from CNCF/The Lunix Foundation. It’s quite popular certifications (as k8s in general), and so there a LOT of study material out there in the Internet. Below is the list of sources I’ve used.
Some of the best blog posts I’ve read described a solution (and the process to get there) someone reached after a lot of struggle.
As always, Julia Evans does a wonderful job explaining that in exquisite details.

TL&DR: If you’re about to miss a deadline, be honest about it, and tell everyone well in advance.
I wish some of the project managers I had the “privilege” of working with would use 1% of that advice.
