FAQ: What’s happening with 5G and airport safety?

Even if you’re not a frequent flyer, you’ve probably heard that the Federal Aviation Administration (FAA) and numerous airlines are claiming that AT&T and Verizon Wireless’s recently approved C-Band 5G will dangerously interfere with airplanes take offs and landings.

Will this new 5G be dangerous? Can a 5G call knock a plane out of the sky? Here’s what we know:

Mirantis brings secure registries to Kubernetes distros

Thanks to Solarwinds and Log4j, we know it’s all too easy to have our systems busted thanks to software supply chain problems. To help us with this, Mirantis, the cloud and container company, has released Mirantis Secure Registry (MSR) 3.0, which can be used to build and deploy secure registries across any Kubernetes distribution.

Mirantis Secure Registry, formerly Docker Trusted Registry, provides an enterprise-grade container registry solution. You can use this as a foundation to build a secure software supply chain. It does this by providing you with access to a container image registry that has enhanced levels of security beyond that of public registries. This, in turn, gives you more control over this critical part of their software supply chain.

Get ready for the ‘Great Shutdown’

This fall, even as the Omicron variant gained steam, we largely pretended it wasn’t that bad. We were wrong.

But that’s not what I’m here to talk about. I want to focus on what you’re going to do when you literally can’t keep your doors open because all your employees are home sick. (It’s already happening.)

In my hometown of Asheville, N.C., schools have closed because the latest spike left the city schools system without enough staff to “maintain facilities operations or hold classes.” Restaurants, already hard hit by the Great Resignation, are also shutting their doors. Retail stores, concert venues, and theaters are following suit, as they can’t keep enough staffers on the floor to take care of customers.

It’s not just where I live. It’s happening everywhere, though perhaps not all at once. In many ways, what we’re seeing are rolling shutdowns. Airlines that can’t get enough pilots or ground crowds. Retail shops with salespeople out. You get the idea.

Open Source Security at the White House

There’s no question that open source security and supply chain security has become top of mind issues in the aftermath of the Apache Log4j security problem quartet and the SolarWinds security fiasco. But so important that the White House would call a meeting with open source foundations and company officials? Yes, it’s that important.

The meeting was led by White House cybersecurity leader Anne Neuberger. Executives and officials from organizations like the Apache Software Foundation (ASF) and the Linux Foundation and executives from Apple, Amazon, Google, IBM, Microsoft, and Oracle. Government agencies such as the Department of Defense and the Cybersecurity and Infrastructure Security Agency (CISA) were also represented.

Open Invention Network expands Linux patent protection

Today, everyone — yes, even Microsoft — use Linux and open-source. It’s been years since Linux was under attack by SCO for imaginary copyright violations, and then Microsoft CEO Steve Ballmer claimed that Linux violated over 200 of Microsoft’s patents. So over 15-years ago, the Open Invention Network (OIN) patent consortium was formed to defend Linux against intellectual property (IP) attacks. Even so, Linux and open-source software are still under attack from patent trolls and other attackers. That’s where the Open Invention Network (OIN) steps up by expanding its patent non-aggression coverage by updating its Linux System definition.

Wireshark creator joins Sysdig to extend it to cloud security

If you’re a real network administrator, you know and love open source Wireshark. For over 15-years, it’s been the tool that professionals use for network traffic protocol analysis. Nothing else even comes close. Now, Sysdig, the container and cloud security company, has hired Gerald Combs, its creator and project leader, to join its open source team. There, Combs will help them with Sysdig-related open-source projects such as  FalcoPrometheuseBPF, and Sysdig Inspect. In addition, Sysdig will sponsor and manage the Wireshark community and extend Wireshark to monitoring and analyzing cloud networks.
