✓ Correct answer: D. Nondiscretionary access control model A nondiscretionary access control model uses a central authority to determine which objects (such as files) that users (and other subjects) can access. In contrast, a discretionary access control model allows users to grant or reject access to any objects they own. An ACL is an example or rule‐based access control model. An access control matrix includes multiple objects, and it lists the subject’s access to each of the objects.
