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 oraccess sensitive data withoutproper protection, such asencryption 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.

Reviewing the last compile date of production programs is the most efficient way to detect unauthorized changes to production programs, as it can quickly identify any discrepancies between the expected and actual dates of program modification. The last compile date is a timestamp that indicates when a program was last compiled or translated from source code to executable code. Any changes to the source code would require a recompilation, which would update the last compile date. The IS auditor can compare the last compile date of production programs with the authorizedchange requests and reports to verify that only approved changes were implemented. The other options are not as efficient as option A, as they are more time-consuming, labor- intensive or error-prone. Manually comparing code in production programs to controlled copies is a method of verifying that the code in production matches the code in a secure repository or library, but it requires access to both versions of code and a tool or technique to compare them line by line. Periodically running and reviewing test data against production programs is a method of verifying that the programs produce the expected outputs and results, but it requires designing, executing and evaluating test cases for each program.
Verifying user management approval of modifications is a method of verifying that the changes to production programs were authorized and documented, but it does not ensure that the changes were implemented correctly or accurately.

The best way to verify the effectiveness of a data restoration process is to perform periodic complete data restorations. This is the process of transferring backup data to the primary system or data center and verifying that the restored data is accurate, complete, and functional. By performing periodic complete data restorations, the auditee can test the reliability and validity of the backup data, the functionality and performance of the restoration tools and procedures, and the compatibility and integrity of the restored data with the primary system. This will also help identify and resolve any issues or errors that may occur during the restoration process, such as corrupted or missing files, incompatible formats, or configuration problems.
Performing periodic reviews of physical access to backup media (option A) is not the best way to verify the effectiveness of a data restoration process, as it only ensures the security and availability of the backup media, not the quality or usability of the backup data. Physical access reviews are important for preventing unauthorized access, theft, damage, or loss of backup media, but they do not test the actual restoration process or verify that the backup data can be successfully restored.
Validating offline backups using software utilities (option C) is also not the best way to verify the effectiveness of a data restoration process, as it only checks the integrity and consistency of the backup data, not the functionality or compatibility of the restored data. Software utilities can help detect and correct any errors or inconsistencies in the backup data, such as checksum errors, duplicate files, or incomplete backups, but they do not test the actual restoration process or verify that the restored data can work with the primary system.
Reviewing and updating data restoration policies annually (option D) is also not the best way to verify the effectiveness of a data restoration process, as it only ensures that the policies are current and relevant, not that they are implemented and followed. Data restoration policies are important for defining roles and responsibilities, objectives and scope, standards and procedures, and metrics and reporting for the restoration process, but they do not test the actual restoration process or verify that it meets the expected outcomes.
Therefore, option B is the correct answer.

The most critical finding when reviewing an organization's information security management is no periodic assessments to identify threats and vulnerabilities. Periodic assessments are essential for ensuring that the organization's information security policies, procedures, standards, and controls are aligned with the current and emerging risks and threats that may affect its information assets. Without periodic assessments, the organization may not be aware of its actual security posture, gaps, or weaknesses, and may not be able to take appropriate measures to mitigate or prevent potential security incidents. No dedicated security officer, no official charter for the information security management system, and no employee awareness training and education program are also findings that may indicate some deficiencies in the organization's information security management, but they are not as critical as no periodic assessments to identify threats and vulnerabilities.
