User accounts provisioning is the process of creating, managing, and modifying user accounts within a system or an application, based on the user’s roles, responsibilities, and requirements. User accounts provisioning is an essential part of identity and access management (IAM), which aims to ensure the confidentiality, integrity, and availability of the system or the application, and the information or resources that it handles or supports1.

The best key performance indicator (KPI) for monitoring adherence to an organization’s user accounts provisioning practices is the percentage of accounts without documented approval, because it can help to measure how well the organization follows the policies, standards, and procedures for user accounts provisioning, and how effectively the organization controls andaudits the user accounts provisioning activities. The percentage of accounts without documented approval can indicate:

The level of compliance and accountability of the user accounts provisioning process, and the extent to which the user accounts provisioning requests and actions are authorized and verified by the appropriate parties, such as managers, IT staff, or security officers

The level of risk and exposure of the user accounts provisioning process, and the likelihood and impact of unauthorized or inappropriate user accounts provisioning, such as granting excessive or unnecessary access privileges, creating duplicate or fraudulent accounts, or violating legal or regulatory requirements

The level of quality and efficiency of the user accounts provisioning process, and the ability and capacity of the organization to manage and maintain the user accounts provisioning records and documents, such as forms, logs, or reports23

The other options are not the best KPIs for monitoring adherence to an organization’s user accounts provisioning practices, but rather some of the factors or outcomes of it. User accountswith default passwords are user accounts that have not changed their passwords from the initial or default values that are assigned by the system or the application. User accounts with default passwords are a factor that can increase the risk of unauthorized or malicious access to the system or the application, as the default passwords may be easily guessed or compromised by attackers. Active accounts belonging to former personnel are user accounts that have not been deactivated or deleted after the users have left the organization. Active accounts belonging to former personnel are an outcome of ineffective or inefficient user accounts deprovisioning, which is the process of revoking or removing the user accounts and access privileges when they are no longer needed or valid. Accounts with dormant activity are user accounts that have not been used or accessed for a long period of time. Accounts with dormant activity are an outcome of poor or inconsistent user accounts management, which is the process of updating or modifying the user accounts and access privileges according to the changes or needs of the users or the organization4. References =
