Data loss can occur due to various reasons, such as accidental deletion, hardware failure, malware infection, theft, or unauthorized access. Data classification procedures can help to identify and protect sensitive data, but they are not sufficient to prevent data loss. The most effective way to protect against data loss is to conduct periodic security awareness training for employees, which can educate them on the importance of data security, the best practices for data handling and storage, and the common threats and risks to data.

An IT balanced scorecard is a strategic management tool that aligns IT objectives with business goals and measures the performance of IT processes using key performance indicators (KPIs). It is the most effective means of monitoring governance of enterprise IT, which is the process of ensuring that IT supports the organization's strategy and objectives. Governance of enterprise IT covers aspects such as IT value delivery, IT risk management, IT resource management, and IT performance measurement. An IT balanced scorecard can help monitor these aspects and provide feedback to improve IT governance. References: ISACA Frameworks: Blueprints for Success, CISA Review Manual (Digital Version)

The missing access control requirements should present the greatest concern to the IS auditor when reviewing a contract for the outsourcing of IT facilities. Access control requirements are essential for ensuring the confidentiality, integrity, and availability of the outsourced IT resources and data. They specify the roles, responsibilities, and permissions of the outsourcing vendor and its staff, as well as the client and its users, in accessing and managing the IT facilities. They also define the security policies, standards, and procedures that the outsourcing vendor must follow to protect the IT facilities from unauthorized or malicious access, use, modification, or disclosure. Without clear and comprehensive access control requirements, the outsourcing contract may expose the client to significant risks of data breaches, compliance violations, service disruptions, or reputational damage.
Hardware configurations, help desk availability, and perimeter network security diagram are important aspects of an outsourcing contract, but they are not as critical as access control requirements. Hardware configurations describe the technical specifications and performance of the IT equipment that the outsourcing vendor will provide and maintain. Help desk availability defines the service levels and support channels that the outsourcing vendor will offer to the client and its users. Perimeter network security diagram illustrates the network architecture and security measures that the outsourcing vendor will implement to protect the IT facilities from external threats. These aspects can be verified or modified during the implementation or operation phases of the outsourcing contract, but access control requirements need to be established and agreed upon before signing the contract.

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 greatest concern for an IS auditor when reviewing IT policies and procedures that are not regularly reviewed and updated is that policies and procedures might not reflect current practices. Policies are documents that define the goals, objectives, and guidelines for an organization's information systems and resources. Procedures are documents that describe the steps, tasks, or activities for implementing or executing policies. Policies and procedures should be regularly reviewed and updated to ensure that they are relevant, accurate, consistent, and effective for the organization's information systems and resources. Policies and procedures that are not regularly reviewed and updated might not reflect current practices, as they might be outdated, obsolete, or incompatible with the current state or needs of the organization's information systems and resources. This can cause confusion, inconsistency, inefficiency, or noncompliance among users or stakeholders who rely on policies and procedures for guidance or direction. Policies and procedures might not include new systems and corresponding process changes is a possible concern for an IS auditor when reviewing IT policies and procedures that are not regularly reviewed and updated, but it is not the greatest one. Policies and procedures might not include new systems and corresponding process changes, as they might be unaware of or unresponsive to the introduction or modification of information systems or resources within the organization. This can cause gaps, overlaps, or conflicts among policies and procedures that affect different information systems or resources.
