Final answer:
To restrict cases to certain users in a system, role-based access control (RBAC) and access control lists (ACLs) can be implemented for fine-grained security.
Step-by-step explanation:
To take advantage of a system's security to restrict cases of a given type to certain users, you can implement role-based access control (RBAC). RBAC is a method of regulating access to a system by assigning users to roles based on their responsibilities and ensuring that they can only access the information necessary to perform their jobs. In addition, utilizing access control lists (ACLs) can help specify which users or groups have access to specific content within the system. Both of these are fundamental security mechanisms that enable fine-grained control over resources and help maintain the system's integrity and confidentiality.
