The best reason to implement a data retention policy is to limit the liability associated with storing and protecting information. A data retention policy is a document that defines how long data should be kept by an organization and how they should be disposed of when they are no longer needed. A data retention policy should comply with the applicable laws and regulations that govern the data retention requirements and obligations of organizations, such as tax laws, privacy laws, or industry standards4. Implementing a data retention policy can help to limit the liability associated with storing and protecting information by reducing the amount of data that need to be stored and secured, minimizing the risk of data breaches or leaks, ensuring compliance with legal or contractual obligations, and avoiding potential fines or penalties for non-compliance5. The other options are less relevant or incorrect because:

• B. Documenting business objectives for processing data within the organization is not a reason to implement a data retention policy, as it is more related to data governance than data retention. Data governance refers to the policies, procedures, and controls that define how data are collected, used, managed, and shared within an organization. Data governance helps to ensure that data are aligned with business objectives and support decision making6.
• C. Assigning responsibility and ownership for data protection outside IT is not a reason to implement a data retention policy, as it is more related to data accountability than data retention. Data accountability refers to the identification and assignment of roles and responsibilities for data protection among different stakeholders within an organization. Data accountability helps to ensure that data are handled appropriately and securely by authorized parties7.
• D. Establishing a recovery point objective (RPO) for disaster recovery procedures is not a reason to implement a data retention policy, as it is more related to data backup than data retention. Data backup refers to the process of creating copies of data that can be restored in case of data loss or corruption. Data backup helps to ensure that data are available and recoverable in case of disaster8. RPO is a measure of the maximum amount of data that can be lost or acceptable in case of disaster9. References: Data Retention Policy - ISACA, Data Retention - ISACA, Data Governance - ISACA, Data Accountability - ISACA, Data Backup - ISACA, Recovery Point Objective - ISACA

 Adequate action taken for noncompliance with the service level agreement (SLA) provides the best evidence that outsourced provider services are being properly managed. This shows that the organization is monitoring the performance of the provider and enforcing the terms of the SLA.

The other options are not as convincing as evidence of proper management. Option A, the SLA includes penalties for non-performance, is a good practice but does not guarantee that the penalties are actually applied or that the performance is satisfactory. Option C, the vendor provides historical data to demonstrate its performance, is not reliable because the data may be biased or inaccurate. Option D, internal performance standards align with corporate strategy, is irrelevant to the question of outsourced provider management.

 Partitioning the work environment from personal space on devices. This would best maintain information security without compromising employee privacy by creating a separate and secure area on the personal mobile devices for work-related data and applications. This way, the organization can protect its information from unauthorized access, loss, or leakage, while respecting the employees’ personal data and preferences on their own devices.

The other options are not as effective as option B in balancing information security and employee privacy. Option A, installing security software on the devices, is a good practice but may not be sufficient to prevent data breaches or comply with regulatory requirements. Option C, preventing users from adding applications, is too restrictive and may interfere with the employees’ personal use of their devices. Option D, restricting the use of devices for personal purposes during working hours, is impractical and difficult to enforce.

The approach adopted by management in this scenario is risk avoidance. Risk avoidance is the elimination of a risk by discontinuing or not undertaking an activity that poses a threat to the organization3. By moving data center operations to another facility on higher ground, management is avoiding the potential flooding risk that could disrupt or damage the data center. Risk transfer, risk acceptance and risk reduction are other possible approaches for dealing with risks, but they do not apply in this case. References:
