This document outlines security considerations, best practices, and recommendations for deploying and using the Justice Definitions Project browser extension in a secure manner.

The Justice Definitions Project extension is designed with security in mind, but proper configuration and deployment practices are essential for maintaining security in production environments.

1. Access Key Authentication: Prevents unauthorized access to your webhook endpoint
2. Rate Limiting: Protects against abuse and DoS attacks
3. Input Validation: Sanitizes and validates all incoming data
4. XSS Protection: Basic protection against cross-site scripting attacks
5. Geographic Logging: Optional IP-based tracking for monitoring
6. Request Logging: Comprehensive logging for audit trails

SECURITY: {
  ENABLE_ACCESS_KEY_VALIDATION: true,  // Always enable in production
  ACCESS_KEY: 'your_secure_key',       // Use a strong, random key
  LOG_REQUESTS: true,                  // Enable for audit trails
  LOG_IP_ADDRESSES: true,              // Enable for monitoring
  LOG_GEOGRAPHY: true                  // Enable for geographic analysis
}

DO:

• Use at least 32 characters
• Include uppercase, lowercase, numbers, and special characters
• Use a cryptographically secure random generator
• Store the key securely (password manager, environment variables)

DON'T:

• Use dictionary words or common phrases
• Use personal information
• Share keys in plain text
• Commit keys to version control

# Using OpenSSL (recommended)
openssl rand -base64 32

# Using Node.js
node -e "console.log(require('crypto').randomBytes(32).toString('base64'))"

# Using Python
python3 -c "import secrets; print(secrets.token_urlsafe(32))"

• Regular Rotation: Change access keys every 90 days
• Emergency Rotation: Change immediately if compromise is suspected
• Update Both Sides: Always update both Apps Script and extension configs simultaneously

• Always use HTTPS for your Google Apps Script deployment
• Verify SSL certificates are valid and up-to-date
• Use secure headers where possible

The extension uses background scripts to bypass CORS restrictions:

• Background scripts have elevated permissions
• Requests are made from the extension context, not the webpage
• This approach is more secure than disabling CORS

RATE_LIMIT_ENABLED: true,
MAX_REQUESTS_PER_HOUR: 1000,      // Adjust based on expected usage
MAX_REQUESTS_PER_MINUTE: 30       // Prevent rapid-fire attacks

1. Monitor Usage Patterns: Adjust limits based on actual usage
2. Implement Graduated Responses: Consider different limits for different user types
3. Log Rate Limit Violations: Monitor for potential attacks
4. Use IP-based Tracking: Combine with user-based tracking for better protection

// Minimal logging (privacy-focused)
SECURITY: {
  LOG_REQUESTS: true,           // Keep audit trail
  LOG_IP_ADDRESSES: false,      // Disable for privacy
  LOG_GEOGRAPHY: false          // Disable for privacy
}

// Full logging (monitoring-focused)
SECURITY: {
  LOG_REQUESTS: true,           // Full audit trail
  LOG_IP_ADDRESSES: true,       // Enable for security monitoring
  LOG_GEOGRAPHY: true           // Enable for usage analytics
}

• Google Sheets: Data persists indefinitely by default
• Apps Script Properties: Rate limiting data auto-expires after 2 hours
• Geolocation Cache: Expires after 5 minutes

1. IP Address Logging: Can be disabled if privacy is a concern
2. Geographic Data: Optional feature for analytics
3. Request Content: Terms and URLs are logged for audit purposes
4. User Agent: Logged for debugging and analytics

1. Regular Log Reviews: Check Google Sheets for unusual patterns
2. Failed Authentication Attempts: Monitor for access key guessing
3. Rate Limit Violations: Watch for potential attacks
4. Geographic Anomalies: Unusual geographic patterns

The system logs:

• Request timestamps
• Source IP addresses (if enabled)
• Geographic location (if enabled)
• Request content (terms and URLs)
• Validation status
• Rate limit status

• Google Sheets: Built-in filtering and sorting
• Google Apps Script Logs: Execution history and errors
• Browser Developer Tools: Client-side debugging

1. Immediate Response:

   • Rotate access keys
   • Check logs for compromise indicators
   • Review recent requests for anomalies

2. Investigation:

   • Analyze log patterns
   • Check for unauthorized access
   • Review rate limiting violations

3. Recovery:

   • Update configurations if needed
   • Implement additional monitoring
   • Document lessons learned

1. Access Key Guessing: Mitigated by strong keys and rate limiting
2. DoS Attacks: Mitigated by rate limiting and request validation
3. Data Injection: Mitigated by input validation and sanitization
4. Information Disclosure: Mitigated by proper error handling

1. Enable All Security Features:

   SECURITY: {
     ENABLE_ACCESS_KEY_VALIDATION: true,
     LOG_REQUESTS: true,
     LOG_IP_ADDRESSES: true,
     LOG_GEOGRAPHY: true
   }

2. Implement Additional Validation:

   • Add custom validation rules
   • Implement request signing
   • Add time-based tokens

3. Monitor and Alert:

   • Set up automated monitoring
   • Create alerts for suspicious activity
   • Regular security reviews

1. Google Account Security:

   • Enable 2FA on your Google account
   • Use strong passwords
   • Regular security checkups

2. Google Apps Script Security:

   • Limit script sharing
   • Regular permission reviews
   • Monitor execution logs

3. Google Sheets Security:

   • Limit sheet sharing
   • Regular access reviews
   • Backup important data

• Generate secure access keys
• Configure rate limiting appropriately
• Enable security logging
• Test all security features
• Review and update all configurations

• Monitor logs regularly
• Check for unusual patterns
• Review access patterns
• Update configurations as needed
• Rotate keys on schedule

• Monthly security reviews
• Quarterly key rotation
• Annual security assessment
• Regular backup verification
• Update documentation

If you discover a security vulnerability:

1. DO NOT create a public GitHub issue
2. DO contact the maintainers privately
3. DO provide detailed information about the vulnerability
4. DO allow reasonable time for response before disclosure
