Comprehensive and Detailed in-Depth Explanation:
The primary role of KPIs is to provide measurable insights into the performance of business processes and identify variances that may require corrective actions. KPIs help organizations understand whether their processes are achieving desired outcomes and where improvements are needed.
While Option A discusses workflow optimization, it is a secondary benefit rather than the primary purpose.
Options B and C do not accurately describe the core purpose of KPIs.

The associated risk of mobile computing that an IS auditor should identify during the planning phase of a data loss prevention (DLP) audit is increased vulnerability due to anytime, anywhere accessibility. Mobile computing refers to the use of portable devices, such as laptops, tablets, smartphones, or wearable devices, that can access data and applications over wireless networks from any location6. Mobile computing enables greater flexibility, productivity, and convenience for users, but also poses significant security challenges for organizations. One of these challenges is increased vulnerability due to anytime, anywhere accessibility. This means that mobile devices are exposed to a higher risk of loss, theft, damage, or unauthorized access than stationary devices7. If mobile devices contain or access sensitive data without proper protection, such as encryption or authentication, they could result in data leakage or breach in case of compromise8. Therefore, an IS auditor should identify this risk as part of a DLP audit. The other options are less relevant or incorrect because:
* A. The use of cloud negatively impacting IT availability is not an associated risk of mobile computing that an IS auditor should identify during the planning phase of a DLP audit, as it is more related to cloud computing than mobile computing. Cloud computing refers to the delivery of computing services, such as data storage or processing, over the Internet from remote servers. Cloud computing may enable or support mobile computing by providing access to data and applications from any device or location, but it does not necessarily imply mobile computing. The use of cloud may negatively impact IT availability if there are disruptions or outages in the cloud service provider's network or infrastructure, but this is not a direct consequence of mobile computing.
* B. Increased need for user awareness training is not an associated risk of mobile computing that an IS auditor should identify during the planning phase of a DLP audit, as it is more of a control or mitigation measure than a risk. User awareness training refers to educating users about security policies, procedures, and best practices for using mobile devices and protecting data. User awareness training may help to reduce the risk of data loss or breach due to mobile computing by increasing user knowledge and responsibility, but it does not eliminate or prevent the risk.
* D. Lack of governance and oversight for IT infrastructure and applications is not an associated risk of mobile computing that an IS auditor should identify during the planning phase of a DLP audit, as it is more of a general or organizational risk than a specific or technical risk. Governance and oversight refer to the establishment and implementation of policies, standards, and procedures for managing IT resources and aligning them with business objectives. Lack of governance and oversight for IT infrastructure and applications may affect the security and performance of mobile devices and data, but it is not a direct or inherent result of mobile computing.

The type of IS audit that would provide the greatest level of assurance that the department's objectives have been met after implementing new technologies and processes is an integrated audit. An integrated audit is an audit that combines financial, operational, compliance, and IT auditing aspects to provide a holistic view of the organization's performance and risks. An integrated audit can evaluate whether the new technologies and processes are aligned with the organization's goals, strategies, policies, and controls, and whether they are delivering value, efficiency, effectiveness, and reliability. The other types of IS audits (A, C and D) would not provide the same level of assurance, as they would only focus on specific aspects of the organization's activities, such as performance, cyber security, or financial reporting, which may not capture the full impact of the new technologies and processes.

The best control to minimize the risk of unauthorized access to lost company-owned mobile devices is device encryption. Device encryption is a process that transforms data on a device into an unreadable format using a cryptographic key. Device encryption protects the data stored on the device from being accessed by unauthorized parties, even if they bypass the password or PIN protection. Device encryption can also prevent data leakage if the device is disposed of or recycled without proper data sanitization. Password or PIN protection is a basic control that prevents unauthorized access to the device by requiring a secret code or pattern to unlock it. However, password or PIN protection can be easily compromised by brute force attacks, shoulder surfing, or social engineering. Device tracking software is a tool that allows the device owner or administrator to locate, lock, or wipe the device remotely in case of loss or theft. However, device tracking software depends on the device's network connectivity and GPS functionality, which may not be available or reliable in some situations. Periodic backup is a process that copies the data from the device to another storage location for recovery purposes. Periodic backup can help restore the data in case of loss or damage of the device, but it does not prevent unauthorized access to the data on the device itself.
