What is Mandatory access control?
In [[computer security]], a '''mandatory access control''' ('''MAC''') means a type of [[access control]] by which the [[operating system]] changes the way a ''subject'' (e.g. a user or a program) can access or do some sort of action on an ''object'' (e.g. a file or folder). Subjects and objects each have a set of security rules. Whenever a subject tries to use an object, the operating system [[Kernel (computer science)|kernel]] looks at these security rules and decides whether the subject can use the object. {{Tech-stub}} [[Category:Computer security]]
