The best way to help management understand the associated risk of missing backup cycles due to operator error and lack of exception management is to explain the impact to disaster recovery. Disaster recovery is the process of restoring normal operations and functions after a disruptive event, such as a natural disaster, a cyberattack, or a hardware failure. Backup cycles are essential for disaster recovery, because they ensure that the organization has copies of its critical data and systems that can be restored in case of data loss or corruption. If backup cycles are missed due to operator error, and these exceptions are not managed, the organization may not have the latest or complete backups available for disaster recovery, which can result in prolonged downtime, reduced productivity, lost revenue, reputational damage, and legal or regulatory penalties. The other options are not as effective as explaining the impact to disaster recovery, because they either do not address the risk of data loss or corruption, or they focus on operational or technical aspects rather than business outcomes.

The IS auditor's greatest concern when reviewing a business case for a proposed implementation of a third- party system should be A. Lack of ongoing maintenance costs. This is because ongoing maintenance costs are an essential part of the total cost of ownership (TCO) of a third-party system, and they can have a significant impact on the return on investment (ROI) and the feasibility of the project. If the business case does not include ongoing maintenance costs, it may underestimate the true cost of the project and overestimate the benefits. This could lead to poor decision making and unrealistic expectations.
Lack of training materials (B), lack of plan for pilot implementation ©, and lack of detailed work breakdown structure (D) are also potential issues that could affect the quality and success of the project, but they are not as critical as lack of ongoing maintenance costs. Training materials can be developed or acquired later, pilot implementation can be planned during the project initiation or planning phase, and work breakdown structure can be refined as the project progresses. However, ongoing maintenance costs are difficult to change or estimate once the project is approved and implemented, and they can have long-term implications for the organization. Therefore, they should be included and analyzed in the business case.

The most important control to assess in an audit of an organization's accounts payable processes is segregation of duties between issuing purchase orders and making payments. Segregation of duties is a principle that requires different individuals or departments to perform different tasks or functions within a process, in order to prevent fraud, errors, or conflicts of interest. In the accounts payable process, segregation of duties between issuing purchase orders and making payments ensures that no one person can initiate and complete a transaction without proper authorization and verification. This reduces the risk of duplicate payments, overpayments, unauthorized payments, or payments to fictitious vendors.

The greatest benefit of adopting an international IT governance framework rather than establishing a new framework based on the actual situation of a specific organization is wide acceptance by different business and support units with IT governance objectives. An international IT governance framework, such as COBIT, provides a common language and understanding for IT governance among various stakeholders, such as management, users, auditors and regulators. This facilitates alignment, communication and collaboration among them. Readily available resources, comprehensive coverage and fewer resources expended are also benefits of adopting an international IT governance framework, but they are not the greatest benefit.

The issue seems to stem from a breakdown in the workflow or process for handling assets that are due for destruction12. By examining the workflow, the IS auditor can identify where the process failed, such as why the vendor was not notified about the hard drives12. This could involve reviewing procedures for inventory management, communication with vendors, and tracking of assets due for destruction12. The findings can then be used to improve the workflow and prevent similar issues in the future12.
