Question 890
During a payment-platform modernization at a payment clearing organization, the IS auditor learns that disk images are collected without cryptographic integrity checks or transfer logs. The affected operation supports merchant settlement and reconciliation. Finance and settlement integrity depend on this operation. Which evidence-gathering approach is MOST aligned with the recorded exposure?
Explanation
Correct Answer
Correct. Inspect seizure, imaging, hash verification, timestamp handling and custody transfers against approved forensic procedures. The procedure directly tests the reported condition that disk images are collected without cryptographic integrity checks or transfer logs. A defensible IS audit conclusion requires relevant and reliable evidence from the actual control population and period.
Incorrect Answers
Not the most direct fieldwork procedure for these facts. The relevant success criterion is evidence appropriate to the audit conclusion; this measures a different function.

Not the most direct fieldwork procedure for these facts. It does not establish the requested evidence appropriate to the audit conclusion outcome.
