In addition, "use of IT and control over it" is achieved by "five viewpoints concerning use of IT" and "two viewpoints concerning IT control."

According to the definitions, IT control is to set objectives for realizing effective internal control, and to manage information systems in companies by taking advantage of IT. IT control is basically automated control activities, and therefore, it includes access control to the mission-critical system or management of IDs or passwords, which effectively functionalizes the access control etc.
