Vulnerability Scanning

Automate security vulnerability detection across code, dependencies, and containers.

Dependency Scanning

# npm audit
npm audit --audit-level=high

# Snyk
snyk test --severity-threshold=high

# Safety (Python)
safety check --full-report

Container Scanning (Trivy)

# Scan container image
trivy image myapp:latest --severity HIGH,CRITICAL

# Scan filesystem
trivy fs --scanners vuln,secret .

Node.js Scanner

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: runScan('npm audit --json'),
    trivy: runScan('trivy fs --quiet --format json .')
  };

  if (!results.npm || !results.npm.metadata) {
    console.warn('npm audit produced no metadata; skipping npm checks');
  } else {
    const critical = results.npm.metadata?.?. || ;
     (critical > ) {
      .();
      process.();
    }
  }
}

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
