This usually results from the first two benefits, applications that install device drivers or require elevated security privileges typically have addition steps involved in their deployment, for example on Windows a solution with no device drivers can be run directly with no installation, while device drivers must be installed separately using the Windows installer service in order to grant the driver elevated privileges Mandatory Vacations[ edit ] Mandatory vacations of one to two weeks are used to audit and verify the work tasks and privileges of employees.
While some of these changes are organisation-wide, most are actually implemented at business unit or even team level. Before John Doe can be granted access to protected information it will be necessary to verify that the person claiming to be John Doe really is John Doe.
