🎯 Security Best Practices

1. Input Validation

- Always validate and sanitize all input data - Use parameterized queries to prevent SQL injection - Implement strict type checking - Validate file uploads and URLs

2. Authentication & Authorization

- Use strong password hashing (bcrypt) - Implement proper session management - Use JWT tokens with short expiration - Implement role-based access control

3. Data Protection

- Encrypt sensitive data at rest - Use HTTPS for all communications - Implement field-level encryption - Regular secret rotation

4. Rate Limiting

- Implement rate limiting for all endpoints - Monitor for DDoS attacks - Block suspicious IP addresses - Log security events

5. Audit Logging

- Log all security-relevant events - Monitor for suspicious activity - Regular security audits - Compliance reporting

🚀 Next Steps

1. Implement input validation for all user inputs 2. Set up authentication with secure password hashing 3. Configure encryption for sensitive data 4. Enable rate limiting and DDoS protection 5. Set up audit logging for security monitoring
