A way to restrict the access to objects based on the sensitivity of the information that is contained in the objects and the official authorization of subjects in order to gain access to information of such sensitivity. Compare with discretionary access control.
Restricts access to objects based on the sensitivity (as represented by a label) of the information contained in the objects and the formal authorization (that is, clearance) of users to access information of such sensitivity. This security feature is available with Secure SQL ServerTM, but not with the standard SQL Server.
A means of restricting access to objects that is based on fixed security attributes assigned to users, files, and other objects. The controls are mandatory in the sense that they cannot be modified by users or their programs.
A means of restricting access to objects based on the sensitivity (as represented by a label) of the information contained in the objects and the formal authorization (i.e., clearance) of subjects to access information of such sensitivity.
A means of restricting access to information based on labels. A user has a label (or clearance) and an object has a label (or classification) which are compared to determine whether access to the object is allowed. Because these access controls are always enforced in addition to any discretionary control implemented by users, this type of security is called mandatory.
In computer security, mandatory access control (MAC) is a kind of access control, defined by the TCSEC
