In the development of an internal campaign to address email phishing, it is crucial to involve key organizational stakeholders who have the authority and insight into both the business and security aspects of the company. This would include Business Unit Leaders, who can represent the needs and concerns of their respective departments, the Chief Information Security Officer (CISO), who has the expertise in security protocols and measures, the Chief Information Officer (CIO), who oversees the overall IT infrastructure, and the Chief Executive Officer (CEO), who provides top-level support and ensures the campaign aligns with the company's strategic goals. The inclusion of these roles ensures a comprehensive approach to addressing email phishing from multiple perspectives within the organization.
