Which of the following is NOT a primary persona in cyber security?

The correct choice identifies a role that does not fit within the primary cybersecurity personas. In the context of cybersecurity, the personas often include positions that are directly responsible for protecting and managing an organization's information security.

CISO (Chief Information Security Officer) or Head of InfoSec is a key leadership role focused on the overall security strategy of an organization. Security Tools Engineers are crucial for implementing and managing security technologies and tools. Incident Responders are essential for reacting to security breaches and managing incidents to minimize damage. Each of these roles is integral to the core functions of cybersecurity.

Marketing Managers, on the other hand, focus on promoting and selling products or services and are not principally involved in the technical or strategic aspects of cybersecurity. While marketing plays a supportive role in any organization, it does not directly contribute to the cybersecurity operations or decision-making processes, which is why this role is not considered a primary persona in cybersecurity.
