Kernel-Level Container Insights: Utilizing eBPF With Cilium, Tetragon, and Sboms for Security
As applications become more distributed, traditional monitoring and security tools are failing to keep pace. This article explores how eBPF, when utilized by the graduated CNCF Cilium and its sub-project Tetragon, combined with Software Bills of Materials (SBOMs), can provide insights and a security feedback loop for modern systems. We’ll create a container image and its SBOM. We’ll then launch it, simulate a breach, and see how our eBPF-based setup with Tetragon captures the issue. This will show how the SBOM can be used to debug and understand the incident.

20 Daily Linux Commands System Administrators Use in Production
As a Linux SysAdmin working in a production environment, your daily routine is all about keeping systems stable, secure, and performing at their best. From troubleshooting issues to monitoring resources and ensuring uptime, you wear many hats, and time is always of the essence.
While Linux offers thousands of commands, not all of them are part of your day-to-day toolbox. However, there’s a core set of powerful, reliable commands that you’ll find yourself using every single day, often multiple times.
In this article, I’ll walk you through the 20 most essential Linux commands every system administrator should master. These aren’t just commands, they’re your go-to tools for monitoring performance, managing logs, controlling services, debugging problems, and much more.

How to Automate Daily Linux Health Checks with a Bash Script + Cron
Managing Linux servers daily can be fun and stressful, especially when you’re dealing with unexpected downtimes or service failures. One thing I’ve learned in my 15+ years as a Linux sysadmin is this: Prevention is better than a cure.
You don’t want to wait for users to report issues. As a sysadmin, your goal should be to detect problems before they affect users or production workloads.
That’s why I always recommend automating daily health checks for your system. If you know ahead of time that disk space is running low or a service has failed, you can fix it before users start shouting.
