Question 360
During a payment-platform modernization at a payment clearing organization, the IS auditor learns that a waterfall handoff leaves no traceability from requirements to test cases. The affected operation supports merchant settlement and reconciliation. Finance and settlement integrity depend on this operation. What result would best demonstrate sustained operation of the corrected control?
Explanation
Correct Answer
Correct. A sampled release has linked requirements, secure review evidence, passed tests and authorized promotion consistent with the method. This is stronger than a manager's verbal assurance because it can be checked against the observed issue that a waterfall handoff leaves no traceability from requirements to test cases. The reviewer must verify the remediation period and scope.
