What is the nature of users that are added to the Vault manually?

The nature of users that are added to the Vault manually often indicates that these users are privileged and require special authorization due to the sensitive access levels associated with the Vault. Manual addition typically involves the intentional and controlled process of integrating individuals who have a specific need for privileged access to critical systems or data, necessitating an extra layer of authorization and oversight.

In a privileged access management system, ensuring that only authorized personnel gain access is crucial for security. These users are often granted permissions that allow them to perform extensive actions that can affect corporate resources. Consequently, they must go through appropriate channels to be added to the Vault, ensuring that their access is justified and monitored.

The other choices refer to aspects that do not align with the nature of manually added users. Automatic provisioning and external system creations represent processes that streamline user management but do not apply to manual entries, nor do built-in users pertain to manual additions as they are predefined within the system. Thus, identifying manual users as those who are privileged and requiring special authorization highlights the importance of security and proper access control in privileged access management systems.
