Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Dockerizing a PHP application is easy; doing it securely takes a few deliberate choices about base images, users, and dependencies. Here is a hardened, production-ready approach.
A Docker image security scan inspects the layers of an image for known-vulnerable packages before you ship it. Here are the tools, commands, and the workflow that keeps scanning useful.
What the Kubernetes runAsUser security context does, how to set it correctly, and the common mistakes that quietly leave pods running as root.
The official Node image on Docker Hub ships in half a dozen flavors, and the tag you pick changes your attack surface far more than most teams realize.
SecurityContext in Kubernetes is where pod and container hardening actually lives — here's what each field controls and which defaults you should never leave in place.
Most container breaches trace back to a handful of avoidable mistakes — root users, bloated images, exposed sockets, unscanned dependencies. This checklist closes them, image to runtime.
The CVEs that hurt clusters lately live at the edges: admission controllers, ingress, and image supply chains. What the recent record says about where to harden first.
A secure PHP Docker setup starts with a supported base tag, a slim image, a non-root user, and a scanned dependency tree. Here is how to get all four.
Node Alpine Docker images cut attack surface and pull times dramatically, but musl libc compatibility gaps mean they're not a drop-in replacement for every Node project.
