This time around, the content is a bit heavier on cloud management and applications/operating systems, but still lots of good content all the way around (I hope, anyway). Jason Edelman has posted a self-compiled list of networking projects that are open source ; this is a useful list, so thanks for compiling it Jason!

I think a fair number of folks may not be aware that the Nginx ingress controller for Kubernetes—both the community version and the Nginx-maintained open source version—do suffer from timeouts and errors resulting from changes in the back-end application’s list of endpoints (think pods being added or removed).

I saw this blog post about Curiefense , an open source Envoy extension to add WAF (web application firewall) functionality to Envoy. I really enjoy these AWS open source news and updates posts. It’s a good starting point for thinking about operating your own active-active architecture.

We all know that security is more than just a host-based firewall, but a host-based firewall can be part of an overall security strategy. This article provides a good introductory overview of Linux iptables commands for configuring host-based firewall rules on your Linux systems. Operating Systems/Applications.

Well, let’s see…stuff on Envoy, network automation, network designs, M1 chips (and potential open source variants!), Ivan Pepelnjak shares some links and thoughts on configuring the NSX-T firewall with a CI/CD pipeline built on GitHub Actions and Terraform Cloud. Are open source M1-style chips a possibility?

It is important to use security tooling such as OpenSCAP, the open source version of the Security Content Automation Protocol, to harden virtual machine images prior to their deployment in virtual private clouds. Vulnerabilities at the operating system level may be exploited by rogue container workloads if not hardened.

How could open source software be vulnerable for so long? That meant I tested the release candidates -- not the final product you’d buy in the stores - for consumer-grade antivirus programs, desktop firewalls, and desktop Intrusion detection systems. How did this happen? That’s the tool side.

Skydive is (in the project’s own words) an “open source real-time network topology and protocols analyzer.” Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration.

Hacking and data breaches are a common thing today, especially with the rise of open source platforms and electronic transactions. A common way for malware to attack is for it to find exploits and vulnerabilities in a system. Anti-virus programs can catch most malicious bugs that enter your system. Turn on your firewall.
