The department shall determine what type of property other than contraband a confined person may not possess and shall inform him of that classification. In carrying out this section, the department may inform a confined person of the type or items of property he is permitted to possess, in which event all other property not contraband is prohibited property. Property that a confined person is otherwise permitted to possess may become prohibited property due to the means by which it is possessed or used.
