Final answer:
In the domain of identity and access management, tasks such as user authentication, role-based access control, and password management are essential and fall under its purview. The correct options are a,c,e.
Step-by-step explanation:
In the domain of identity and access management (IAM), certain tasks are essential for securing and managing user identities and permissions within an IT environment. The following tasks are part of the IAM domain:
- User authentication: This is the process of verifying the identity of a user before granting them access to systems and resources.
- Role-based access control (RBAC): A method of regulating access to computer or network resources based on the roles of individual users within an organization.
- Password management: A practice that involves the creation, storage, and management of user credentials, particularly passwords, ensuring that access to systems is secure and compliant with policies.
Other tasks like system backup and data encryption, while important for IT security, do not fall directly under the purview of IAM.
