Mandatory Access Control (MAC)

Mandatory Access Control (MAC) is a security approach that restricts user access to information based on established rules set by a central authority. Unlike letting users decide their permissions, MAC enforces strict policies, classifying data and user clearance levels. For example, some users may only see sensitive information if their security clearance matches or exceeds the data’s classification. This method ensures high security, especially in sensitive environments like government or military systems, by preventing unauthorized access and reducing the risk of data leaks or breaches.
