The primary consideration when implementing controls for monitoring user activity logs is ensuring that the control is proportional to the risk, because this helps to optimize the balance between the benefits and costs of the control, and to avoid over- or under-controlling the risk. User activity logs are records of the actions or events performed by users on IT systems, networks, or resources, such as accessing, modifying, or transferring data or files. Monitoring user activity logs can help to detect and prevent potential threats, such as unauthorized access, data leakage, or malicious activity, and to support the investigation and remediation of incidents. However, monitoring user activity logs also involves certain costs and challenges, such as collecting, storing, analyzing, and reporting large amounts of log data, ensuring the accuracy, completeness, and timeliness of the log data, protecting the privacy and security of the log data, and complying with the relevant laws and regulations. Therefore, when implementing controls for monitoring user activity logs, the organization should consider the level and impact of the risk that the control is intended to address, and the value and effectiveness of the control in reducing the risk exposure and impact. The organization should also consider the costs and feasibility of implementing and maintaining the control, and the potential negative consequences or side effects of the control, such as performance degradation, user dissatisfaction, or legal liability. By ensuring that the control is proportional to the risk, the organization can achieve the optimal level of risk management, and avoid wasting resources or creating new risks. References = Risk IT Framework, ISACA, 2022, p. 151
