Question 70
During a follow-up assurance engagement at a telecommunications provider, the IS auditor learns that a weekly exception report is presented as a control that prevents real-time fraud. The affected operation supports customer provisioning and billing. Service availability and accurate customer billing depend on the process. What control exposure MOST directly explains why this observation is significant?
Explanation
Correct Answer
Correct. Controls may not address the intended risk at the correct point because their preventive, detective or corrective roles are misunderstood. The described exception is: a weekly exception report is presented as a control that prevents real-time fraud. This risk ties the observation to the business significance of customer provisioning and billing, rather than treating management's claim as independent assurance.
Incorrect Answers
Biased or incomplete samples can produce unsupported conclusions about how a control operates across the actual population. It does not retain the evidence appropriate to the audit conclusion control over time.
Insufficiently reliable or relevant evidence can cause an auditor to accept controls that did not operate as described. Recurrence here depends on evidence appropriate to the audit conclusion, not this safeguard.
Audit conclusions may lack objectivity when independence is impaired by self-review, incentives or undisclosed conflicts. That protection can exist while evidence appropriate to the audit conclusion is still missing.
