The application of information technologies in the business of modern organizations is taken for granted today. The sustainability of an organization without the implementation of information technologies in almost all business functions of that organization is not possible.

The domain of information systems audit is both accounting and non-accounting information systems. This paper deals with defining the subject and role of information system audit.
