Which of the following provides an IS auditor assurance that the interface between a point-of-sale (POS) system and the general ledger is transferring sales data completely and accurately?
Electronic copies of customer sales receipts being maintained directly relates to verifying the completeness and accuracy of sales data. By having these electronic receipts, an IS auditor can cross-verify the sales data transmitted from the POS system to the general ledger, thereby providing assurance that the data transfer is accurate and complete.
b is answer
Transaction totals and record counts should be sent and reconciled before transaction processing: This control ensures that the number of transactions sent from the sales office to the production warehouse is equal to the number of transactions received at the warehouse. Additionally, the total value of the transactions sent should match the total value of the transactions received. By comparing the transaction totals and record counts before transaction processing, any errors or omissions can be detected and corrected before production begins. This helps to prevent incomplete or inaccurate orders from being processed.
B. Monthly bank statements are reconciled without exception.
While monthly bank statement reconciliation (Option B) is an important financial control process, it does not directly address the assurance needed regarding the completeness and accuracy of sales data transferred between the POS system and the general ledger. Maintaining electronic copies of customer sales receipts (Option A) is more directly relevant to verifying the integrity of sales data and would provide the IS auditor with greater assurance in this regard.
Why not B
C. The data transferred over the POS interface is encrypted. Encrypting the data transferred over the Point-of-Sale (POS) system interface helps ensure that the sales data is secure during transmission and that it cannot be tampered with or intercepted by unauthorized parties. While options A, B, and D may be relevant for different aspects of POS and financial system security and reliability, they do not specifically address the assurance of data completeness and accuracy between the POS system and the general ledger.
it is confidentiality,. not integrity.
