To ensure Connected App implementations meet security review requirements and avoid vulnerabilities, follow these comprehensive practices:
**Secure Authentication Implementation:**
1. **Use OAuth 2.0**: Use OAuth 2.0 for authentication and avoid using session IDs for external API calls
2. **JWT Authentication**: If using JWT authentication, securely store private keys in protected custom settings or metadata
3. **Proper Access Controls**: Implement proper access controls and limit the app's scope to least privilege necessary
4. **Avoid Insecure Methods**: Do not use session IDs for authentication; use OAuth tokens instead
**Component and Data Security:**
1. **Avoid Exposing Sensitive Components**: Do not expose sensitive components like Lightning Message Channels in managed packages, as they can pose security risks
2. **Secure External Endpoints**: Ensure all external endpoints use HTTPS for communication and avoid insecure HTTP channels
3. **Protect Sensitive Data**: Replace public custom metadata containing sensitive information with protected metadata objects to prevent public access
4. **Secure Storage**: Store sensitive data such as client secrets and access tokens securely using encryption and protected custom metadata or settings
**OAuth Scope and Permission Management:**
1. **Define OAuth Scopes Carefully**: Ensure OAuth scopes are not overly permissive and follow the principle of least privilege
2. **Scope Impact Assessment**: If lowering the scope of the Connected App, ensure it does not impact the functionality of previous package versions
3. **Document Changes**: Document changes as false positives if necessary, with reasoning for the security review
**Testing and Validation:**
1. **Thorough Testing**: Test your solution, including external endpoints, using manual and automated security scanning tools
2. **Address Vulnerabilities**: Address all identified vulnerabilities and document any false positives with proper reasoning
3. **Regular Updates**: Regularly review and update your implementation to align with Salesforce security guidelines and best practices
**Documentation and Support:**
1. **Proper Documentation**: Document any changes to connected apps and mark them as false positives if they do not pose a security risk
2. **Salesforce Support**: Raise a case with Salesforce Support for guidance on specific implementation challenges
3. **Technical Office Hours**: Schedule technical office hours appointments with the AppExchange security review team through the Partner Security Portal
**Deprecation Management:**
1. **Careful Deprecation**: If a connected app is no longer in use, deprecate it carefully to avoid breaking functionality for users of older app versions
**Common Vulnerability Reasons:**
Even recommended authentication processes might be flagged as vulnerabilities if they:
- Use insecure methods like session IDs instead of OAuth tokens
- Fail to implement proper access controls
- Expose sensitive components or lack sufficient protection for sensitive data
- Don't fully adhere to security best practices
By implementing these practices carefully, you can ensure your Connected App meets all security guidelines and protects sensitive information effectively.
