Which of the following is best described as an access control model that focuses on subjects and identifies the object that each subject can access?

The capability table is indeed best described as an access control model that emphasizes subjects and the specific objects each subject can access. This model operates on the principle of associating a user (the subject) with various permissions or capabilities that define what resources (the objects) they can access and to what extent. Each entry in the capability table specifies a subject and the corresponding objects they are allowed access to, effectively detailing their permissions in a clear, organized manner.

Capability tables are particularly advantageous for dynamic systems, as they can be easily updated to reflect changes in user permissions or resource availability. This model contrasts with other access control methods, which may focus more on either user roles or predefined rules rather than a direct association between subjects and their permissions on specific objects. This structure allows for fine-grained access control and enhances security by limiting access to only those subjects that should have it based on their designated capabilities.
