Explanation When an IS auditor discovers a security weakness in the database configuration, the next course of action should be to identify existing mitigating controls. This involves assessing whether any controls are already in place to address the weakness and mitigate the risk. Understanding the current state of controls helps the auditor determine the severity of the issue and whether additional corrective actions are necessary1.
