This document explains the comprehensive security automation system implemented for the Ariane project.

The repository includes a fully automated security system that:

• Detects vulnerabilities across all dependencies and code
• Fixes security issues automatically when safe
• Monitors for new threats continuously
• Reports security status transparently

File: .github/dependabot.yml

• Daily updates for site and studio dependencies
• Weekly updates for GitHub Actions and Docker images
• Auto-merge enabled for patch/minor/security updates
• Grouped updates for related packages (Astro, TypeScript, etc.)

File: .github/workflows/auto-security-fixes.yml

Triggers:

• Daily at 2 AM UTC (scheduled)
• When Dependabot creates PRs
• Manual trigger via workflow_dispatch

Actions:

• Runs npm audit on all projects
• Applies npm audit fix automatically
• Tests builds after fixes
• Auto-commits security patches
• Auto-merges safe Dependabot PRs

File: .github/workflows/security-scanning.yml

Triggers:

• Every push to main
• All pull requests
• Weekly on Sundays at 3 AM UTC

Scans:

• CodeQL - JavaScript/TypeScript code analysis
• Trivy - Dependency and Docker vulnerabilities
• Snyk - Additional vulnerability detection
• TruffleHog - Secret detection
• GitLeaks - Git history secret scanning

Enhanced in: .github/workflows/deploy-zitadel.yml

Pre-deployment:

• Security audit of all dependencies
• Automatic vulnerability fixes
• Secret pattern detection
• Trivy configuration scanning

Dependabot PRs are automatically approved and merged if:

• ✅ Security updates (any severity)
• ✅ Patch version updates (e.g., 1.2.3 → 1.2.4)
• ✅ Minor version updates (e.g., 1.2.0 → 1.3.0)
• ❌ Major version updates (requires manual review)

• Security summaries on every PR
• Weekly vulnerability reports uploaded as artifacts
• Security configuration status tracked monthly
• Auto-fix reports for transparency

• ✅ Vulnerability alerts - Get notified of new CVEs
• ✅ Security updates - Dependabot creates PRs for vulnerabilities
• ✅ Secret scanning - Detect committed secrets
• ✅ Push protection - Block pushes containing secrets
• ✅ Code scanning - Automated CodeQL analysis

• Branch protection for main branch
• Require status checks before merging
• Require up-to-date branches
• Two-factor authentication for all contributors

Run the security setup workflow manually:

# Go to Actions tab → "Security Setup & Configuration" → "Run workflow"

Check these locations regularly:

• Security tab - View active alerts and advisories
• Actions tab - Monitor automated scans and fixes
• Pull requests - Review Dependabot updates

• High/Critical vulnerabilities - Auto-fixed daily
• Medium vulnerabilities - Auto-fixed weekly
• Manual review needed - Tagged with labels, assigned to maintainers

Edit .github/dependabot.yml:

allow:
  - dependency-type: "direct"
    update-type: "security"      # Always auto-merge security
  - dependency-type: "direct"
    update-type: "version-update:semver-patch"  # Auto-merge patches

Edit workflow schedules:

schedule:
  - cron: '0 2 * * *'  # Daily at 2 AM UTC

Add steps to security workflows:

- name: Custom Security Check
  run: |
    # Your custom security validation

1. Check branch protection rules
2. Verify PR passes all required checks
3. Ensure Dependabot has proper permissions

1. Check workflow logs in Actions tab
2. Verify tokens and permissions
3. Review scan configuration

1. Add exclusions to scan configurations
2. Use .trivyignore for Trivy
3. Configure CodeQL query filters

Track security improvements:

• Vulnerability count trends (should decrease)
• Mean time to fix (should decrease)
• Auto-fix success rate (should increase)
• Manual intervention frequency (should decrease)

1. Immediate: Security scans will detect within 24 hours
2. Auto-fix: Applied automatically if safe
3. Manual: Tagged and assigned if requires intervention
4. Deployment: Blocks deployment if critical

1. Detection: Multiple scanning tools provide coverage
2. Response: Auto-removal if possible, manual review otherwise
3. Rollback: Deployment pipeline includes automatic rollback

1. Notification: Check Security tab and email alerts
2. Assessment: Review scan results and affected components
3. Mitigation: Use automated fixes or manual intervention
4. Documentation: Track in security issues
