Question 490
During an outsourced-services renewal at a logistics group, the IS auditor learns that a message broker replay changes business balances with no reconciliation. The affected operation supports freight tracking and fleet operations. Delivery commitments and partner data flow through this process. What control exposure MOST directly explains why this observation is significant?
Explanation
Correct Answer
Correct. Interfaces can silently drop, duplicate or alter business data without adequate completeness and integrity checks. The described exception is: a message broker replay changes business balances with no reconciliation. This risk ties the observation to the business significance of freight tracking and fleet operations, rather than treating management's claim as independent assurance.
Incorrect Answers
Service measures that omit consumer outcomes or lack reliable calculation can conceal contractual and operational failures. It changes a different feature than evidence appropriate to the audit conclusion.
Inadequate response and root-cause practices can prolong service disruption and allow repeat incidents. The configuration must instead establish evidence appropriate to the audit conclusion.
Available infrastructure may not deliver committed business service capacity under peak load or shared failures. The evidence appropriate to the audit conclusion prerequisite remains unaddressed.
