Title

The VMM must reveal system error messages only to authorized users. (Cat II impact)

Discussion

Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can identify the VMM or platform. Additionally, Personally Identifiable Information (PII) and operational information must not be revealed through error messages to unauthorized personnel or their designated representatives. The structure and content of error messages must be carefully considered by the organization and development team. The extent to which the VMM is able to identify and handle error conditions is guided by organizational policy and operational requirements.
