Udene Fraud Detection SDK for React Native

# Security Best Practices

This document outlines security best practices for using the Udene React Native SDK.

## API Key Management

1. **Never hardcode API keys** in your application code. Instead, use:
   - Environment variables with a package like `react-native-config`
   - Secure storage solutions like `react-native-keychain`
   - Remote configuration services

2. **Use different API keys** for development, staging, and production environments.

3. **Implement key rotation** procedures for regular updates of API keys.

## Data Handling

1. **Minimize sensitive data collection**. Only collect what you absolutely need.

2. **Sanitize all data** before sending it to the API. The SDK includes automatic sanitization, but you should also validate user inputs.

3. **Implement proper data retention policies** and delete sensitive data when no longer needed.

## Network Security

1. **Use HTTPS for all API requests**. The SDK enforces this by default.

2. **Consider implementing certificate pinning** for additional security in high-risk applications.

3. **Monitor network traffic** for suspicious patterns or data leakage.

## Error Handling

1. **Implement proper error handling** to avoid exposing sensitive information to users.

2. **Log errors securely** without including sensitive data in logs.

3. **Use custom error messages** for users that don't reveal implementation details.

## Device Security

1. **Check device integrity** using the `getDeviceFingerprint()` method before processing sensitive operations.

2. **Implement additional verification** for high-risk devices or suspicious activities.

3. **Consider implementing app-level encryption** for sensitive data stored on the device.

## Keeping Updated

1. **Always use the latest version** of the SDK to benefit from security updates.

2. **Subscribe to security notifications** for the SDK and its dependencies.

3. **Regularly audit your application** for security vulnerabilities.

## Reporting Security Issues

If you discover a security vulnerability in the SDK, please report it by emailing [security@udene.com](mailto:security@udene.com). Do not disclose security vulnerabilities publicly until they have been handled by the security team.
