How to Harden Ubuntu SSH: From static keys to cloud identity

30 years after its introduction, Secure Shell (SSH) remains the ubiquitous gateway for administration, making it a primary target for brute force attacks and lateral movement within enterprise environments. For system administrators and security architects operating under the weight of regulatory frameworks like SOC2, HIPAA, and PCI-DSS, default SSH configurations are an “open door” that represents an unacceptable risk.

The "scanner report has to be green" trap

In the modern DevSecOps world, CISOs are constantly looking for signals in the noise, and the outputs of security scanners often carry a lot of weight. A security scan that returns a “zero CVE” report often unlocks promotion to production; a single red flag can block a release. This binary view of security has birthed two diametrically opposed philosophies. On one side, we have the long-term support (LTS) approach: stay on a battle-tested version and backport specific security fixes.

In a world built by code, design lives between the lines

Design is the art of solving problems; open source makes that visible. In this video, Open Source Designer Eriol Fox dives into the pragmatic world of design and usability within the FOSS ecosystem. We discuss how product designers and user researchers are driving long-term software sustainability through accessibility and smarter design.

Hot code burns: the supply chain case for letting your containers cool before you ship

In September 2025, dozens of popular JavaScript packages, like chalk and debug, were compromised on the npm registry. These packages are so ubiquitous they end up in everything: front-end apps, back-end microservices, and CI tooling. Developers didn’t do anything wrong, they just ran the same command they always do: npm install chalk. But then the malware arrived silently. This wasn’t a bug in an operating system. It wasn’t a virus on someone’s laptop.

Introducing MicroCloud Cluster Manager

Today, we’re excited to introduce the beta release of MicroCloud Cluster Manager, a new way to discover, organize, and operate your MicroCloud environments from a single, unified interface. MicroCloud is an open source cloud platform that makes it simple to create lightweight, resilient clusters anywhere. As teams scale from one cluster to many, visibility and coordination quickly become essential. Cluster Manager is built to solve exactly that.

Building a dry-run mode for the OpenTelemetry Collector

Teams continuously deploy programmable telemetry pipelines to production, without having access to a dry-run mode. At the same time, most organizations lack staging environments that resemble production – especially with regards to observability and other platform-level services.

The fallacy of complacent distroless containers

Join us on our deep dive into Chisel: the tool that brings enterprise-grade traceability to ultra-minimal container images. In this video, we explain why Chisel was created, and how it helps address security challenges in modern container images. We cover why container images often include unnecessary software and dependencies, why building minimal distroless containers can be difficult, and how missing metadata can lead to false confidence in vulnerability scans.
