A single point of contact within the organization is the most important element to include when incorporating media communication procedures into the security incident communication plan because it helps to ensure a consistent and accurate message to the public and avoid confusion or misinformation. A single point of contact is a designated person who is authorized and trained to communicate with the media on behalf of the organization during a security incident. The single point of contact should coordinate with the incident response team, senior management, legal counsel, and public relations to prepare and deliver timely and appropriate statements to the media, as well as to respond to any inquiries or requests. A single point of contact also helps to prevent unauthorized or conflicting disclosures from other employees or stakeholders that may harm the organization’s reputation or legal position. Therefore, a single point of contact within the organization is the correct answer.
