Describe the two key elements of the MAC model.

What will be an ideal response?

Labels. In a system using MAC, every entity is an object (laptops, files, projects, and so on) and is assigned a classification label. These labels represent the relative importance of the object, such as confidential, secret, and top secret. Subjects (users, processes, and so on) are assigned a privilege label (sometimes called a clearance). Levels. A hierarchy based on the labels is also used, both for objects and subjects. Top secret has a higher level than secret, which has a higher level than confidential.
