Minimal Base Images for Security: A Practical Guide
Minimal base images cut CVE counts by up to 95% by shipping only what your app needs. Here is how to choose between distroless, Wolfi, Alpine, and scratch — and build on each safely.
Securing Managed Kubernetes: EKS, AKS, and GKE Compared
A cross-cloud guide to hardening managed Kubernetes — the shared responsibility line, cloud IAM-to-pod integration, network policy, Pod Security Standards, and node hardening across EKS, AKS, and GKE.
Trivy vs Grype: A Neutral Open-Source Scanner Comparison for 2026
Trivy and Grype are both free, open-source vulnerability scanners loved by engineers, but they differ in scope and philosophy. An honest side-by-side, plus where a managed third option fits.
Docker Secrets Management: Stop Baking Credentials Into Images
A secret written into a Docker layer is recoverable forever, even after you delete it. Learn the build-time and runtime patterns that keep credentials out of your images entirely.
Containers Not Dropping Default Linux Capabilities
Docker grants every container 14 Linux capabilities by default. Here's why NET_RAW, SYS_CHROOT, and friends turn contained compromises into breakouts—and how to drop them safely.
Containers Running in Privileged Mode: Risks and Fixes
Docker's --privileged flag strips seccomp, AppArmor, and capability limits in one line. Here's how attackers exploit it, real CVEs, and how to lock it down.
CVE-2024-21626: runc process.cwd Container Breakout Deep ...
A technical breakdown of CVE-2024-21626, the runc process.cwd() flaw enabling container breakout to host access, with detection and remediation guidance.
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.
Distroless vs Alpine: Which Base Image Is More Secure?
Alpine is tiny and familiar; distroless is tinier and shell-free. The right choice depends on what you value more — debuggability or a minimal attack surface. Here is the honest tradeoff.
Cloud Workload Protection: A Practical Guide to CWPP in 2026
What cloud workload protection (CWPP) actually covers across VMs, containers, and serverless — how it differs from CSPM and CNAPP, what to configure, and where build-time scanning fits.
Scanning Docker Images in CI/CD Pipelines
Scanning a container after it deploys is an incident report. Scanning it in the pipeline is a one-line diff. Here is how to gate builds on image scans without drowning developers in false positives.
Container Image Scanning Best Practices
A practical guide to container image scanning: when to scan, what to block, what scanners like Snyk miss, and how to build a policy that actually gets remediated.
