When preparing an audit report the IS auditor should ensure that the results are supported by:

A.
statements from IS management.

B.
workpapers of other auditors.

C.
an organizational control self-assessment.

D.
sufficient and appropriate audit evidence.

Explanation:
ISACA’s standard on ‘reporting’ requires the IS auditor have sufficient and appropriate audit evidence to support
the reported results. Statements from IS management provide a basis for obtaining concurrence on matters
that cannot be verified with empirical evidence. The report should be based on evidence collected during the
course of the review even though the auditor may have access to the work papers of other auditors. The results
of an organizational control self-assessment (CSA) could supplement the audit findings. Choices A, B and C
might be referenced during an audit but, of themselves, would not be considered a sufficient basis for issuing a
report.
