# Vulnerability Scanning
Automate security vulnerability detection across code, dependencies, and containers.
## Dependency Scanning
```bash
# npm audit
npm audit --audit-level=high
# Snyk
snyk test --severity-threshold=high
# Safety (Python)
safety check --full-report
```
## Container Scanning (Trivy)
```bash
# Scan container image
trivy image myapp:latest --severity HIGH,CRITICAL
# Scan filesystem
trivy fs --scanners vuln,secret .
```
## GitHub Actions Integration
```yaml
name: Security Scan
on: [push, pull_request]
jobs:
security:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Run Trivy vulnerability scanner
uses: aquasecurity/trivy-action@master
with:
scan-type: 'fs'
severity: 'CRITICAL,HIGH'
exit-code: '1'
- name: Run Snyk
uses: snyk/actions/node@master
env:
SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
with:
args: --severity-threshold=high
- name: npm audit
run: npm audit --audit-level=high
```
## Code Analysis (Bandit for Python)
```bash
bandit -r src/ -ll -ii
```
## Node.js Scanner
```javascript
const { execSync } = require('child_process');
+ function runScan(command) {
+ try {
+ return JSON.parse(execSync(command, { stdio: ['pipe', 'pipe', 'ignore'] }).toString());
+ } catch (err) {
+ // A tool may be missing, exit non-zero, or print non-JSON output (e.g.
+ // trivy progress text when not on a TTY). Treat that as "no parseable
+ // result" rather than crashing the scanner.
+ console.warn(`Scan command failed or returned non-JSON: ${command}`);
+ return null;
+ }
+ }
+
function runSecurityScan() {
const results = {
- npm: JSON.parse(execSync('npm audit --json').toString()),
- trivy: JSON.parse(execSync('trivy fs --format json .').toString())
+ npm: runScan('npm audit --json'),
+ trivy: runScan('trivy fs --quiet --format json .')
};
- const critical = results.npm.metadata?.vulnerabilities?.critical || 0;
- if (critical > 0) {
- console.error(`Found ${critical} critical vulnerabilities`);
- process.exit(1);
+ if (!results.npm || !results.npm.metadata) {
+ console.warn('npm audit produced no metadata; skipping npm checks');
+ } else {
+ const critical = results.npm.metadata?.vulnerabilities?.critical || 0;
+ if (critical > 0) {
+ console.error(`Found ${critical} critical vulnerabilities`);
+ process.exit(1);
+ }
}
}
```
## Best Practices
- Integrate scanning in CI/CD pipeline
- Fail builds on high/critical findings
- Scan dependencies and containers
- Track vulnerabilities over time
- Document accepted false positives
## Tools
- Trivy (containers, filesystem)
- Snyk (dependencies, code)
- npm audit / yarn audit
- Bandit (Python)
- OWASP Dependency-Check
