Final answer:
To provide access rights for an employee to access confidential information, Monica should use the Access Control List feature of a network operating system, as well as possibly implementing Role-Based Access Control for managing permissions based on user roles.
Step-by-step explanation:
Monica, a network administrator, wants to provide access rights to an employee authorized to access confidential information. To achieve this, she should use the Access Control List (ACL) feature of a network operating system. This feature allows her to specify which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in an ACL specifies a subject and an operation; for example, a user might be given permission to read a file or to execute a program.
In addition to ACLs, Monica might also consider implementing Role-Based Access Control (RBAC), where access rights are based on the roles that individual users have within the system. Using RBAC, Monica can easily manage user rights and permissions based on their specific role within the organization, thus simplifying the administration of access rights. It also helps in maintaining a higher level of security by ensuring that employees only have the necessary privileges to accomplish their tasks.
