Which of the following is the MOST important key performance indicator (KPI) for monitoring the user access management process?

While managing multiple accounts per user is a consideration, it doesn't directly measure the effectiveness of timely access removal, which is a higher security priority.

This KPI directly measures the effectiveness and timeliness of the offboarding process, which is crucial for preventing unauthorized access by former employees or compromised accounts. Failing to disable accounts within the SLA timeframe creates significant security vulnerabilities by leaving dormant or potentially exploitable access open.

The ratio of privileged to non-privileged accounts is an indicator of privilege distribution but not the primary measure of the efficiency and security of the access management process itself.

The percentage of unactivated accounts might indicate an inefficient provisioning process, but it doesn't represent the most critical security aspect of managing existing user access like timely deactivation.
