Dockerfile Security Root User & Multi-Stage Build Screener
Audits Dockerfile build instructions for insecure root execution (missing USER directive) and multi-stage hygiene.
Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.
How it works
Standard: CIS Docker Benchmark / Container Security Best Practices
Formula: Check for non-root USER directive prior to ENTRYPOINT/CMD execution
Checks: Dockerfile instruction string verification
