Question 800
During a payment-platform modernization at a payment clearing organization, the IS auditor learns that a medical IoT sensor uses an unchanged factory credential. The affected operation supports merchant settlement and reconciliation. Finance and settlement integrity depend on this operation. What test BEST distinguishes effective control operation from an unsupported assertion?
Explanation
Correct Answer
Correct. Inventory managed devices and test credential, encryption, isolation, patch and remote-wipe arrangements. The procedure directly tests the reported condition that a medical IoT sensor uses an unchanged factory credential. A defensible IS audit conclusion requires relevant and reliable evidence from the actual control population and period.
