 User Access Management:

Effective user access management ensures that accounts are properly created, managed, and disabled to prevent unauthorized access.

Monitoring the percentage of accounts disabled within the SLA helps ensure that the organization responds promptly to changes in user status, reducing the risk of unauthorized access.

 Importance of KPI:

This KPI measures the efficiency and effectiveness of the user access management process by tracking how quickly accounts are disabled when no longer needed.

A high percentage indicates timely action, reducing the risk of orphaned accounts being exploited.

 Comparing Other KPIs:

Proportion of End Users Having More Than One Account:Useful but not directly related to the timeliness of disabling accounts.

Proportion of Privileged to Non-Privileged Accounts:Important for monitoring privilege distribution but does not measure process efficiency.

Percentage of Accounts Not Activated:Indicates potential inefficiencies but does not address the risk of active accounts.
