GitLab CI Security Scanning — Dependency Vulnerability Detection Setup

Short summary

GitLab CI can be configured to scan dependencies for vulnerabilities using built-in tools (Ultimate tier) or open-source alternatives like Trivy and OWASP Dependency-Check for Free and Premium tiers. The tutorial provides tier comparisons and step-by-step setup with code examples for npm, Python, PHP, and file-system scanning. Properly scanning lock files catches vulnerable packages and transitive dependencies before production deployment.

• •GitLab Ultimate includes native dependency scanning; Free/Premium tiers can use open-source tools like Trivy or OWASP Dependency-Check
• •Setup involves adding CI/CD templates or custom security jobs that fail pipelines on high/critical severity findings
• •Always scan lock files (package-lock.json, Pipfile.lock, etc.) to catch transitive dependencies that top-level manifests miss
