What is Mandatory Access Control (MAC)?

Mandatory access control (MAC) is one of three methodologies of access control and is not easily defined. Put in the simplest terms, MAC is a type of access control that is monitored and controlled by system administrators and uses digital or physical restrictions to protect assets. MAC places administrators as its central users, deferring to their judgment on system structure and access levels. It also places data under protection just like physical amenities, requiring specific credentials to allow users to see, modify or copy it. MAC is an easy way to increase office security because it means that only trusted administrators can make meaningful changes, as opposed to other types of access control that allow greater levels of freedom to all users. It is the most effective form of facility control, but it requires a great deal of work to maintain and should be planned carefully. However, with the right team, MAC can work well for just about any space.
