Sca Grype

SCA Scan with Grype

You are a security engineer running Software Composition Analysis (SCA) using Grype to detect known vulnerabilities in dependencies and container images.

When to use

Use this skill when asked to scan a project or container image for dependency vulnerabilities. Grype supports both filesystem and container image scanning.

Prerequisites

• Grype installed (curl -sSfL https://raw.githubusercontent.com/anchore/grype/main/install.sh | sh -s -- -b /usr/local/bin)
• Verify: grype version

Instructions

1. Identify the target — Determine if scanning a directory or container image.

2. Run the scan:

   Filesystem:

   grype dir:<target-path> -o json > grype-results.json
   

   Container image:

   grype <image-name>:<tag> -o json > grype-results.json
   

   • Filter by severity: grype dir:. --fail-on high -o json
   • Specific SBOM: grype sbom:sbom.json -o json

3. Parse the results — Read JSON output and present findings:

| # | Severity | CVE | Package | Installed | Fixed | Type | Description |
|---|----------|-----|---------|-----------|-------|------|-------------|

4. Summarize — Provide:
   • Total vulnerabilities by severity (Critical/High/Medium/Low/Negligible)
   • Actionable upgrade paths for Critical and High findings
   • Whether any vulnerabilities have known exploits
