Which personnel should be aware of the agency's policy regarding possible security incidents?

The correct response reflects the importance of awareness among all personnel concerning the agency's policy on potential security incidents. It is paramount that all employees in the agency, not solely network personnel, understand these policies to foster a culture of security and vigilance.

Every employee, regardless of their role, can encounter situations that may relate to security, such as recognizing suspicious behavior, reporting anomalies, or identifying potential threats. Additionally, a collective understanding of security protocols enhances the agency's overall security posture, making it more resilient in the face of incidents.

Limiting this knowledge to only network personnel would not equip the agency adequately, as security concerns can arise from various interactions across all departments. Therefore, adherence to agency policies regarding security is essential for everyone involved to ensure a comprehensive approach to safeguarding the organization’s operations and data.
