What is the set of rules that defines access rights to resources on a computer called?

The correct answer refers to "Permissions," which are specific settings that dictate what actions users can or cannot perform on particular resources within a computer system. Permissions control access to files, folders, applications, and other objects based on user roles or specific user accounts.

In the context of computer systems, permissions are crucial because they help maintain the integrity and security of the system by ensuring that only authorized users can access or modify resources. For example, a user might have permission to read a document but not to delete it, which helps prevent accidental or unauthorized changes.

Other terms that are related but distinct from permissions include Access Control List (ACL), which is a document that details the permissions granted to specific users or groups for a particular resource. Policies may outline broader security measures and guidelines rather than specific access rights. User rights refer to the privileges assigned to users regarding system operations but do not specifically detail access to individual resources. Understanding this difference is essential for effective management and security in IT environments.
