Which control aims to identify errors after they have occurred?

The control that aims to identify errors after they have occurred is known as a detection control. These controls are implemented to monitor activities and processes, allowing for the identification of discrepancies, inaccuracies, or errors that may arise during operations. An example of a detection control might be regular audits, variance analyses, or error reports that highlight issues post-factum, enabling an organization to respond to and rectify issues effectively.

Preventive controls, on the other hand, are designed to stop errors or irregularities from occurring in the first place, such as implementing policies, staff training, or physical security measures. Corrective controls focus on fixing identified errors and addressing issues after detection has taken place. Discretionary controls refer to measures that are based on judgment or authority, allowing flexibility in how they are applied but may not specifically target error identification or correction in a systematic way. Thus, detection controls play a crucial role in ensuring errors are recognized and can be addressed, which establishes their importance in overall internal control systems.
