Best practices for containerizing .NET applications securely
.NET 8 gave containers a built-in non-root user and chiseled images that cut one team's CVE count 92% — most Dockerfiles still don't use either.
Reducing Docker image build time without sacrificing security
Multi-stage builds and minimal base images can cut CI build times dramatically — and they're the same changes that shrink your CVE attack surface.
Alpine vs Debian Base Image Security: Which Is Safer?
Alpine is tiny and dodged the xz backdoor; Debian has deeper security tracking and broader compatibility. Here is how the two base images actually compare on security — and how to harden either one.
Alpine vs distroless: which base image is more secure
Alpine and distroless both shrink attack surface differently. We compare real CVEs, musl risks, and patch tradeoffs to settle which base image actually wins.
Reducing CVEs in container base images
Base images inherit hundreds of OS-level CVEs your app never touches. Here's how reachability analysis and minimal bases cut real risk, not just counts.
Best Container Base Images for Security in 2026
Chainguard, distroless, Alpine, UBI micro, Ubuntu chiseled, and scratch, compared on CVE counts, size, libc, and the operational costs nobody puts in the marketing.
The Minimal Base Image Myth: What Actually Reduces Attack Surface
Alpine, distroless, and scratch images don't automatically cut risk. The real attack-surface drivers are capabilities, root filesystem, network policies, and seccomp.
Alpine vs Distroless vs Ubuntu Base Images: Security Tradeoffs
Alpine is small, distroless is smaller, Ubuntu is comfortable. The real security question is CVE surface vs debuggability vs compatibility — with numbers.
Zero-CVE Images vs Hardening Your Own: Cost and Risk Compared
Buy zero-CVE base images or build hardened ones yourself? A cost-and-risk comparison with real numbers: engineering hours, subscription pricing, and CVE half-life.
Distroless vs. Chainguard vs. Wolfi: Real Differences
A working engineer's comparison of Google Distroless, Chainguard Images, and Wolfi as base images, covering what actually breaks in production and what does not.
Alpine vs Debian base image vulnerability comparison
A 2026 look at Alpine vs. Debian base image CVEs shows raw vulnerability counts mislead — patch cadence and reachability matter more than distro choice.
How Snyk Container's Base Image filter isolates OS-level ...
How Snyk Container's Base Image filter separates OS-level vulnerabilities from application dependencies, how it identifies base images, and where attribution breaks down.
