Simplifying container security with Snyk’s security expertise

Open-source software and layered container images accelerate development but can introduce vulnerabilities through base images and their Linux packages, making container security more complex than scanning application code alone. Because Linux distributions such as Alpine, Debian, Ubuntu, and Red Hat independently maintain, rename, version, patch, and assess packages differently, upstream vulnerability information cannot be directly applied to every distribution or image; Log4Shell is presented as an example of differing package names and fixed versions. Variations in security terminology, severity ratings, advisory data, package backports, and the large volume of dependencies further complicate vulnerability triage. Snyk’s Container Security Team addresses these challenges by collecting distribution-specific security data, collaborating with Linux security teams, applying automated processing alongside human expert review, enriching findings with external signals, and contextually prioritizing issues through severity and priority scores. Planned improvements include insights that distinguish build-time from runtime risks, additional metadata on fix availability and vulnerability status, and broader support for Linux distributions.
