Implementation Details

1. CodeQL Analysis

File: .github/workflows/codeql.yml

Automated static analysis for security vulnerabilities.

name: CodeQL Analysis

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]
  schedule:
    - cron: '0 6 * * 1'  # Weekly on Monday

jobs:
  analyze:
    runs-on: ubuntu-latest
    permissions:
      actions: read
      contents: read
      security-events: write

    strategy:
      matrix:
        language: ['javascript', 'typescript']

    steps:
      - uses: actions/checkout@v4

      - name: Initialize CodeQL
        uses: github/codeql-action/init@v3
        with:
          languages: ${{ matrix.language }}

      - name: Autobuild
        uses: github/codeql-action/autobuild@v3

      - name: Perform CodeQL Analysis
        uses: github/codeql-action/analyze@v3
        with:
          category: /language:${{ matrix.language }}

Scans For:

• SQL injection
• Cross-site scripting (XSS)
• Command injection
• Path traversal
• Insecure cryptography
• Authentication bypass
• Information disclosure

2. Dependabot Configuration

File: .github/dependabot.yml

Automated dependency updates.

version: 2
updates:
  - package-ecosystem: npm
    directory: /
    schedule:
      interval: weekly
      day: monday
      time: "09:00"
    open-pull-requests-limit: 10
    reviewers:
      - ShunsukeHayashi
    labels:
      - dependencies
      - automated
    commit-message:
      prefix: "chore(deps)"
      include: "scope"
    versioning-strategy: increase

  - package-ecosystem: github-actions
    directory: /
    schedule:
      interval: weekly
    open-pull-requests-limit: 5
    labels:
      - github-actions
      - automated
    commit-message:
      prefix: "ci"

Features:

• Weekly npm dependency updates
• GitHub Actions version updates
• Automatic PR creation
• Reviewer assignment
• Semantic versioning strategy

3. Secret Scanning

Enabled via GitHub UI:

Repository → Settings → Security → Code security and analysis
→ Enable Secret scanning
→ Enable Push protection

Detects:

• API keys (GitHub, AWS, Azure, etc.)
• Database credentials
• Private keys
• OAuth tokens
• Webhook secrets

Push Protection:

• Blocks commits containing secrets
• Provides remediation guidance
• Allows bypass with justification

4. Vulnerability Reporting

File: SECURITY.md

Defines security policy and reporting process.

# Security Policy

## Supported Versions

| Version | Supported          |
| ------- | ------------------ |
| 2.x     | :white_check_mark: |
| 1.x     | :x:                |

## Reporting a Vulnerability

### Private Reporting

For security vulnerabilities, please use GitHub's private reporting:

1. Go to Security tab
2. Click "Report a vulnerability"
3. Fill in the form with details

### What to Include

- Description of vulnerability
- Steps to reproduce
- Potential impact
- Suggested fix (if any)

### Response Timeline

- **Acknowledgment**: Within 24 hours
- **Initial Assessment**: Within 72 hours
- **Fix Timeline**: Based on severity
  - Critical: 7 days
  - High: 14 days
  - Medium: 30 days
  - Low: 90 days

### Disclosure Policy

- Coordinated disclosure after fix
- 90-day disclosure timeline
- Credit to reporter (if desired)

## Security Best Practices

### For Contributors

1. Never commit secrets or credentials
2. Use environment variables
3. Keep dependencies updated
4. Follow secure coding guidelines
5. Enable 2FA on GitHub account

### For Users

1. Keep installation updated
2. Use strong GitHub tokens
3. Limit token permissions
4. Review Dependabot PRs
5. Enable secret scanning

5. Security Scanning Workflow

File: scripts/security-report.ts

Generates security report from GitHub Security API.

import { Octokit } from '@octokit/rest';

async function generateSecurityReport() {
  const octokit = new Octokit({ auth: process.env.GITHUB_TOKEN });

  // Fetch vulnerabilities
  const { data: alerts } = await octokit.rest.dependabot.listAlertsForRepo({
    owner: 'ShunsukeHayashi',
    repo: 'Miyabi',
    state: 'open',
  });

  // Fetch CodeQL results
  const { data: analyses } = await octokit.rest.codeScanning.listRecentAnalyses({
    owner: 'ShunsukeHayashi',
    repo: 'Miyabi',
  });

  const report = {
    timestamp: new Date().toISOString(),
    vulnerabilities: {
      critical: alerts.filter(a => a.security_advisory.severity === 'critical').length,
      high: alerts.filter(a => a.security_advisory.severity === 'high').length,
      medium: alerts.filter(a => a.security_advisory.severity === 'medium').length,
      low: alerts.filter(a => a.security_advisory.severity === 'low').length,
    },
    codeql: {
      latestScan: analyses[0]?.created_at,
      status: analyses[0]?.error || 'success',
    },
  };

  console.log('📊 Security Report\n');
  console.log(`Critical: ${report.vulnerabilities.critical}`);
  console.log(`High: ${report.vulnerabilities.high}`);
  console.log(`Medium: ${report.vulnerabilities.medium}`);
  console.log(`Low: ${report.vulnerabilities.low}`);

  return report;
}

Completion Criteria and KPIs

Key Performance Indicators

Testing Methodology

CodeQL Testing

# Test locally with CodeQL CLI
codeql database create ./codeql-db --language=javascript
codeql database analyze ./codeql-db --format=sarif-latest --output=results.sarif

Dependabot Testing

1. Create outdated dependency in package.json
2. Wait for Dependabot PR (or trigger manually)
3. Review PR and merge
4. Verify update applied

Secret Scanning Testing

# Test push protection (should block)
echo "github_token: ghp_1234567890abcdef" > test.txt
git add test.txt
git commit -m "Test secret scanning"
git push  # Should be blocked

Troubleshooting Guide

Issue: CodeQL Scan Failing

Solutions:

1. Check workflow syntax
2. Verify language matrix correct
3. Review build logs
4. Ensure dependencies install

Issue: Dependabot Not Creating PRs

Solutions:

1. Check dependabot.yml syntax
2. Verify schedule configuration
3. Check open PR limit not reached
4. Review Dependabot logs

Issue: Secret Scanning False Positives

Solutions:

1. Use test fixtures properly
2. Mark as false positive in UI
3. Add to allow list (with justification)
4. Update secret patterns if needed
