Select True оr Fаlse fоr the fоllowing stаtements relаted to Access Control. In Discretionary Access Control (DAC), the owner of an object determines which users or processes may access that object. [DAC] In Mandatory Access Control (MAC), individual users determine and assign access rights to objects they own. [MAC] In Role-Based Access Control (RBAC), permissions are assigned to roles, and users may be assigned multiple roles. [RBAC] An Access Control Matrix (ACM) directly maps subjects to objects and specifies the allowed operations between them. [ACM]
