If you discover a security vulnerability in this example SPA, please report it by:

1. Opening a GitHub Issue: Create an issue with the "security" label
2. Email: Contact the maintainer directly at rustynations@gmail.com

Please include:

• Description of the vulnerability
• Steps to reproduce
• Potential impact
• Suggested fix (if available)

• Initial Response: Within 48 hours
• Status Update: Within 7 days
• Fix Timeline: Varies based on severity and complexity

When using this example as a starting point for your own SPA:

1. Dependencies: Regularly update dependencies to patch security vulnerabilities

   npm audit
   npm audit fix

2. Environment Variables: Never commit sensitive data (API keys, secrets) to version control

   • Use .env.local for local development (add to .gitignore)
   • Configure production secrets in AWS Systems Manager Parameter Store or Secrets Manager

3. Authentication: Implement proper authentication (AWS Cognito recommended)

   • Don't store credentials in localStorage without encryption
   • Use secure session management
   • Implement proper CORS policies

4. API Security:

   • Use HTTPS for all API calls
   • Implement proper API authentication (API keys, JWT tokens)
   • Validate and sanitize all user inputs

5. CloudFront:

   • Enable AWS WAF for DDoS protection
   • Configure appropriate cache policies
   • Use Origin Access Control (OAC) for S3 bucket security

This is an example application for demonstration purposes. Before using in production:

• Add comprehensive input validation
• Implement proper error handling
• Add security headers (CSP, HSTS, etc.)
• Configure logging and monitoring
• Implement rate limiting for API calls
• Add automated security testing to CI/CD pipeline
