MAC (Mandatory Access Control)
Mandatory Access Control (MAC) is a security approach where a system strictly enforces access permissions based on established policies. It categorizes data and user privileges, ensuring individuals can only access information they are authorized for, regardless of their role or preferences. Think of it as a security lockdown where permissions are centrally set and unchangeable by users, preventing unauthorized access or modifications. MAC is commonly used in sensitive environments, such as government or military systems, to protect classified information by maintaining strict control over data access based on security levels.
