Mandatory Access Control

Summary

Mandatory Access Control (MAC) is a security model that restricts access to resources based on the sensitivity of the information and the level of clearance of the user.

Detailed Description

In a Mandatory Access Control system, access rights are regulated by a central authority based on multiple security levels assigned to both users and objects (resources). Unlike Discretionary Access Control (DAC) systems, where the owner of a resource can grant access to others, MAC restricts users from altering access rights. This model is prevalent in environments where data security is critical, such as military and government applications.
