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.
Keeping track of user accounts is very important, especially as a Linux server administrator. In this episode of Linux Essentials, we’ll explore user and password expiration. This will include examples regarding locking passwords, the chage command, and more!

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.
Migrating your servers from one Linux distribution to another can be a daunting task, even moreso if it’s a migration you’re doing because of unforeseen events or changes within the ecosystem. In this video, Jay and Joao discuss the challenges when it comes to migrating Linux distributions, and the effect this has on security.
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.
