The best course of action for the risk practitioner is to follow the incident reporting procedures established by the organization. This will ensure that the incident is properly documented, escalated, and resolved in a timely and consistent manner. Reporting the incident to the chief risk officer, advising the employee to forward the email to the phishing team, or advising the employee to permanently delete the email are not the best courses of action, as they may not comply with the organization's policies and standards, and may not address the root cause and impact of the incident.
