The complexity of the technical environment of information systems keeps growing. At the same time, business' or management's dependance on information technology keeps increasing, making the proper functioning of their systems a prerequisite to achieving their strategic objectives. In addition, for businesses, recent regulatory developments, the financial security law, and the Sarbane Oxley Act strengthen requirements for the efficiency of internal control, which is largely supported by information systems. Validation of these controls often requires diving into these programs, networks, and their parameters, and makes a computer-system audit inevitable. For you, internal or external auditors, information system specialists, or financial auditors required to take these issues into account, this hub is a place for discussion, for sharing experience, for technical or commercial networking.
