The Least Privilege Principle declares that a subject should have access to the minimum privilege required to complete a specific task. If no access right is needed, the subject won’t have it. Moreover, the functional management of the subject will control the assignment of rights. In addition, the principle is also interpreted for the application of advancing discretionary access control (DAC) permissions. For instance, if you provide subject U with read/write access to a particular file F, the least privilege principle is violated since U can complete the tasks using only read permission.
