Enterprise Linux Security Episode 7 – ELevate
Remaining on legacy Linux distributions can lead to additional security risks as time goes on, and migrating to a newer and better supported distribution can be a very difficult endeavor for most administrators. In this episode, Jay and Joao are joined by Jack from AlmaLinux, and we talk about ELevate – a tool that can be used to migrate from a distribution in the Enterprise Linux family to another Enterprise Linux distribution. This helps alleviate some of the burden of distro migration, and as a community project it’s also a great project to get started with contributing to an open-source project.

Enterprise Linux Security Episode 6 – Image Defaults
Although there’s no such thing as a “perfect” deployment image, including some sane defaults into your images and templates can save you a lot of work down the road, and also give you the opportunity to include more secure defaults. In this episode, we’ll discuss deployment image defaults as well as some recent news.

Enterprise Linux Security Episode 4 – Supply Chain Attacks

When you write software, there’s no reason to reinvent the wheel – shared libraries and other resources exist to enable you to create applications while avoiding redundant work. Unfortunately, sometimes the software supply itself chain is attacked, which would mean that your application contain malware or security threats you didn’t account for. In this episode of Enterprise Linux Security, Joao and I discuss supply chain attacks, as well as some ways to mitigate this threat.

Live-patching QEMU with QEMUCare

Rebooting is a pain, and in some organizations, downright tedious. Shuffling virtual machines between hosts in a cluster is even more tedious, and when it’s time to install patches, that’s what many administrators are forced to do. In this video, I check out QEMUCare, which aims to live-patch QEMU to avoid VM shuffling. In particular, we’ll look at installing ePortal (which deploys the patches) and also an example scenario.

Special “SysAdmin Day” 2021 Panel Discussion

System Administrator Appreciation Day is a special day of recognition that occurs on the last Friday of July each year. SysAdmin Day is intended to bring recognition to all the hard work that System Administrators perform to keep our systems running. In this video, I discuss SysAdmin Day (as well as many other topics surrounding the line of work) with Joao Correia from CloudLinux, and Brian from Admin Magazine. This was an awesome discussion, so don’t miss out!

I had a chance to sit down with Joao Correia from CloudLinux and Brian Osborn from Admin Magazine to talk about System Administrators Appreciation Day, System Administration in general, and why we need to help our Admins feel more appreciated it.
