According to the CISSP CBK Official Study Guide1, the identity management process in which the subject’s identity is established is enrollment. Enrollment is the process of registering or enrolling a subject into an identity management system, such as a user into an authentication system, or a device into a network. Enrollment is the process in which the subject’s identity is established, as it involves verifying and validating the subject’s identity, as well as collecting and storing the subject’s identity attributes, such as the name, email, or biometrics of the subject. Enrollment also involves issuing and assigning the subject’s identity credentials, such as the username, password, or certificate of the subject. Enrollment helps to create and maintain the subject’s identity record or profile, as well as to enable and facilitate the subject’s access and use of the system or network. Trust is not the identity management process in which the subject’s identity is established, although it may be a factor that influences the enrollment process. Trust is the degree of confidence or assurance that a subject or an entity has in another subject or entity, such as a user in a system, or a system in a network. Trust may influence the enrollment process, as it may determine the level or extent of the identity verification and validation, as well as the identity attributes and credentials that are required or provided for the enrollment process. Provisioning is not the identity management process in which the subject’s identity is established, although it may be a process that follows or depends on the enrollment process. Provisioning is the process of creating, assigning, and configuring a subject’s account or resource with the necessary access rights and permissions to perform the tasks and functions that are required by the subject’s role and responsibilities, as well as the security policies and standards of the system or network. Provisioning is not the process in which the subject’s identity is established, as it does not involve verifying and validating the subject’s identity, or collecting and storing the subject’s identity attributes or credentials. Authorization is not the identity management process in which the subject’s identity is established, although it may be a process that follows or depends on the enrollment process. Authorization is the process of granting or denying a subject’s access or use of an object or a resource, based on the subject’s identity, role, or credentials, as well as the security policies and rules of the system or network. Authorization is not the process in which the subject’s identity is established, as it does not involve verifying and validating the subject’s identity, or collecting and storing the subject’s identity attributes or credentials. References: 1
