Abstract

This report aims to explain the importance of systems audit after the emergence of the Sarbanes-Oxley Act (Sox Act) in the United States and its impacts on the financial audit based on tests of the automated internal controls in an attempt to reduce the risk of control. For this, we present the main test methodologies for systems audit, compared with the Sox Act requirements. Still, it will be presented a comparative empirical study of two mining companies, operating in Minas Gerais, besides highlighting its key controls related to the safety of their automated environment.
