An IT control is a procedure or policy that provides a reasonable assurance that the information technology (IT) used by an organization operates as intended, that data is reliable and that the organization is in compliance with applicable laws and regulations. IT Controls can be categorized as either general controls (ITGC) or application controls (ITAC).
An IT general control should demonstrate that the organization has a procedure or policy in place for technology that affects the management of fundamental organizational processes such as risk management, change management, disaster recovery and security. IT application controls, which are actions that a software application does automatically, should demonstrate that software applications used for specific business processes (such as payroll) are properly maintained, are only used with proper authorization, are monitored and are creating audit trails.Content Continues Below
