Question 350
During a post-incident audit at a retail marketplace, the IS auditor learns that a cloud investment is approved despite an untested key integration assumption. The affected operation supports customer checkout and order fulfillment. Customer transactions and market trust depend on effective control. Which audit procedure would MOST directly validate the suspected control gap?
Explanation
Correct Answer
Correct. Recalculate total lifecycle costs and benefits, test major assumptions and assess measurable benefit ownership and feasibility. The procedure directly tests the reported condition that a cloud investment is approved despite an untested key integration assumption. A defensible IS audit conclusion requires relevant and reliable evidence from the actual control population and period.
