The auditor's best course of action is to document the finding and explain the risk of having administrator accounts with inappropriate security settings. This is because the auditor's role is to identify and report the issues, not to fix them or request others to fix them. The auditor should also communicate the impact of the finding, such as the possibility of unauthorized access, data tampering, or denial of service attacks. The auditor should not assume the responsibility of the IT manager or the DBA, who are in charge of changing the security parameters or disabling the accounts. References:
