Question 860
During a payment-platform modernization at a payment clearing organization, the IS auditor learns that high-severity events are drowned by repeated benign telemetry with no tuning. The affected operation supports merchant settlement and reconciliation. Finance and settlement integrity depend on this operation. During fieldwork, what is the BEST focused test of this condition?
Explanation
Correct Answer
Correct. Trace injected or historical test events from source ingestion through detection rules, triage and escalation records. The procedure directly tests the reported condition that high-severity events are drowned by repeated benign telemetry with no tuning. A defensible IS audit conclusion requires relevant and reliable evidence from the actual control population and period.
