Users in your network are able to assign permissions to their own shared resources. Which of the following access control models is used in your network?

Discretionary access control (DAC) allows data owners to assign permissions. Role-based access control (RBAC) assigns access based on the role the user is in. Mandatory access control (MAC) is stricter and enforces control at the OS level. Attribute-cased access control (ABAC) considers various attributes such as location, time, and computer in addition to user- name and password.
