Mandatory access control

Mandatory Access Control (MAC) is a way of controlling who can access different kinds of information, like on a computer. It's like having a lot of locks that only certain people have the keys to open. For example, a company might have an employee database that only the manager can open. MAC helps to keep the data safe and secure, meaning that only the people with the right key can access the information.
