The best evidence that an organization's IT strategy is aligned to its business objectives is that the IT strategy is approved by executive management. This implies that the IT strategy has been reviewed and validated by the senior leaders of the organization, who are responsible for setting and overseeing the business objectives. The IT strategy may be modified in response to organizational change, based on IT operational best practices, or have significant impact on the business strategy, but these are not sufficient indicators of alignment without executive approval.

The best criteria for monitoring an IT vendor's service levels are the performance metrics, as they provide quantifiable and measurable indicators of how well the vendor is delivering the agreed-upon services, such as availability, reliability, quality, timeliness, and customer satisfaction. A service auditor's report is a document that provides an independent opinion on the vendor's controls and processes, but it may not reflect the actual service levels or performance. A surprise visit to the vendor may help to verify the vendor's compliance and operations, but it may not be feasible or effective for monitoring the service levels on a regular basis. An interview with the vendor may help to obtain feedback and insights from the vendor's perspective, but it may not be objective or reliable for monitoring the service levels.

The best method to prevent wire transfer fraud by bank employees is system-enforced dual control. System- enforced dual control is a segregation of duties control that requires two or more individuals to perform or authorize a transaction or activity using a system that enforces this requirement. System-enforced dual control can prevent wire transfer fraud by requiring independent verification and approval of payment requests, amounts, and recipients by different bank employees using a system that does not allow any single employee to complete the transaction alone. The other options are not as effective as system-enforced dual control in preventing wire transfer fraud, as they do not involve independent checks or approvals using a system.
Independent reconciliation is a detective control that can help compare and confirm payment records with bank statements, but it does not prevent wire transfer fraud from occurring. Re-keying of wire dollar amounts is an input control that can help detect any errors or discrepancies in payment amounts, but it does not prevent wire transfer fraud from occurring. Two-factor authentication control is an access control that can help verify the identity and authorization of bank employees, but it does not prevent wire transfer fraud from occurring.

The most critical finding that the IS auditor should consider when reviewing processes for importing market price data from external data providers is that the quality of the data is not monitored. This is because market price data is essential for financial transactions, risk management, valuation and reporting, and any errors or inaccuracies in the data can have significant impact on the organization's performance, reputation and compliance. The IS auditor should ensure that the organization has established quality criteria and controls for the imported data, such as validity, completeness, timeliness, consistency and accuracy, and that the data is regularly checked and verified against these criteria. The other findings are also important, but not as critical as data quality. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7
