The best key performance indicator (KPI) of the effectiveness of the policy requiring staff members to take a minimum of five consecutive days leave per year to mitigate the risk ofmalicious insider activities is the percentage of staff members taking leave according to the policy. A KPI is a quantifiable measure that evaluates the performance of a process, activity, or outcome against a predefined target or objective. The percentage of staff members taking leave according to the policy is the best KPI, because it directly measures the compliance and adherence of the staff members to the policy, which is the main objective of the policy. The policy aims to reduce the risk of malicious insider activities by forcing the staff members to take a break from their work, which can help to deter, detect, or prevent any fraudulent or unauthorized actions, such as data theft, sabotage, or manipulation12. The percentage of staffmembers taking leave according to the policy can also help to evaluate the effectiveness and efficiency of the policy implementation and enforcement, and to identify and address any gaps or issues in the policy design or execution. The other options are not the best KPI, although they may be related or influential to the policy effectiveness. The number of malicious activities occurring during staff members’ leave is a measure of the occurrence and impact of the risk events that the policy aims to mitigate, but it is not a direct measure of the policy performance or compliance. The number of malicious activities occurring during staff members’ leave may also be affected by other factors or controls, such as the security systems, the audit procedures, or the external threats, which may not reflect the policy effectiveness. The percentage of staff members seeking exception to the policy is a measure of the resistance or dissatisfaction of the staff members to the policy, but it is not a direct measure of the policy performance or compliance. The percentage of staff members seeking exception to the policy may also be influenced by other factors or circumstances, such as the workload, the personal preferences, or the organizational culture, which may not indicate the policy effectiveness. The financial loss incurred due to malicious activities during staff members’ leave is a measure of the consequence and severity of the risk events that the policy aims to mitigate, but it is not a direct measure of the policy performance or compliance. The financial loss incurred due to malicious activities during staff members’ leave may also vary depending on the type, scale, or frequency of the malicious activities, or the recovery or compensation actions, which may not represent the policy effectiveness.
