FAQ-001093 - Lightning Message Channel Security / Alternative Communication Methods

The recommended migration path for customers relying on exposed Lightning Message Channels involves: 1. **Remove the Exposed Channel**: Remove the exposed channel from the managed package to eliminate security risks. 2. **Guide Customer Implementation**: Direct customers to create their own Lightning Message Channels for integration purposes. This ensures the channel remains private to the package while allowing necessary functionality. 3. **Provide Deployment Support**: Offer an unlocked package to help customers with the deployment process and transition. 4. **Update References**: Ensure all references to the previously exposed channel are updated to use the new private implementation. This approach maintains functionality while adhering to security requirements and reduces risks associated with exposed channels.

The FAQ content is accurate and well-structured, addressing the security concerns around exposed Lightning Message Channels and providing a clear migration path. The answer effectively explains how to transition from exposed channels (which pose security risks) to private implementations while maintaining functionality. No significant changes are needed as the content already follows best practices and provides actionable guidance. The related security rule AvoidLmcIsExposedTrue directly applies because this FAQ is specifically about migrating away from Lightning Message Channels with isExposed=true (which this rule flags as a security issue). The FAQ content discusses 'exposed Lightning Message Channels that must now be made private' and provides guidance on removing exposed channels and implementing private alternatives, which directly aligns with what this security rule is designed to prevent.
