Which access control model enables the owner of the resource to specify what subjects can
access specific resources?

A.
Discretionary Access Control

B.
Mandatory Access Control

C.
Sensitive Access Control

D.
Role-based Access Control

Explanation:
Discretionary Access Control (DAC) is used to control access by restricting a
subject’s access to an object. It is generally used to limit a user’s access to a file. In this type of
access control it is the owner of the file who controls other users’ accesses to the file.
Using a DAC mechanism allows users control over access rights to their files. When these rights
are managed correctly, only those users specified by the owner may have some combination of
read, write, execute, etc. permissions to the file.
