Event Bus Public Access

Ensure that EventBridge event bus is configured to prevent exposure to public access.

The default event bus in your Amazon account only allows events from one account. You can grant additional permissions to an event bus by attaching a resource-based policy to it.

Configure EventBridge event bus policies that allow access to whitelisted/trusted account principals but not public access.
