Title

The NSX vCenter must reveal error messages only to authorized individuals (ISSO, ISSM, and SA). (Cat II impact)

Discussion

Only authorized personnel must be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state. Additionally, sensitive account information must not be revealed through error messages to unauthorized personnel or their designated representatives.

Check Content

Verify the application must reveal error messages only to authorized individuals.

View each role and verify the users and/or groups assigned to it. Application service account and user required privileges must be documented. If any user or service account has more privileges than required, this is a finding.
