Performing Sca Dependency Scanning With Snyk

This skill covers implementing Software Composition Analysis (SCA) using Snyk to detect vulnerable open-source dependencies in CI/CD pipelines. It addresses scanning package manifests and lockfiles, automated fix pull request generation, license compliance checking, continuous monitoring of deployed applications, and integration with GitHub, GitLab, and Jenkins pipelines.

# Performing SCA Dependency Scanning with Snyk

## When to Use

- When applications use open-source packages that may contain known vulnerabilities
- When compliance requires tracking and remediating vulnerable dependencies (PCI DSS, SOC 2)
- When needing automated fix PRs for vulnerable dependencies in CI/CD
- When license compliance requires visibility into open-source license obligations
- When continuous monitoring is needed for newly disclosed vulnerabilities in deployed dependencies

**Do not use** for scanning proprietary application code for logic vulnerabilities (use SAST), for runtime vulnerability detection (use DAST), or for container OS package scanning alone (use Trivy for a free alternative).

## Prerequisites

- Snyk account (free tier covers up to 200 tests per month for open source)
- Snyk CLI installed or Snyk GitHub/GitLab integration configured
- SNYK_TOKEN environment variable set with API authentication token
- Project with supported package manifests: package.json, requirements.txt, pom.xml, go.mod, Gemfile, etc.

## Workflow

### Step 1: Install and Authenticate Snyk CLI

```bash
# Install Snyk CLI
npm install -g snyk

# Authenticate with Snyk
snyk auth $SNYK_TOKEN

# Test the connection
snyk test --json | jq '.summary'
```

### Step 2: Scan Dependencies in CI/CD Pipeline

```yaml
# .github/workflows/dependency-scan.yml
name: Dependency Security Scan

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]
  schedule:
    - cron: '0 8 * * 1'  # Weekly Monday 8am

jobs:
