Internal Control Considerations for Information System Changes and Patches
Abstract
The dependence of businesses on properly functioning information systems to allow organizational personnel and outside investors to make important decisions has never been more pronounced. Information systems are constantly evolving due to operational and security requirements. These changes to information systems involve a risk that they could occur in a way that results in improper processing of information and/or security issues. The purpose of this chapter is to consider related guidance provided in a Global Technology Audit Guide (GTAG) from The Institute of Internal Auditors in conjunction with current change and patch management literature in order to assist internal auditors and organizational personnel in better understanding a process that leads to efficient and effective information system changes. The authors describe how internal auditors and information technology professionals can work together with organization management to form a mature approach in addressing both major information system changes and patches.
