Which role should be excluded from all security incident groups once the Security Incident Administrator is added?

When designating roles in a security incident response team, the role of the Security Incident Administrator is focused on managing and coordinating the response process. Including an Admin role in security incident groups may lead to complications, as Admins typically have elevated privileges and access that can interfere with the investigation and integrity of the incident response.

Excluding the Admin from these groups helps maintain a clear separation of duties. This separation is vital to avoid any potential conflicts of interest or the abuse of power during an investigation. In contrast, Security Analysts, Incident Responders, and Client Managers have specific roles that contribute to the incident response process, including analyzing data, responding to incidents, and managing communication with stakeholders, respectively. Keeping these roles in the group is essential for a comprehensive and effective response. Thus, the exclusion of the Admin role is justified to ensure a focused and manageable incident response effort.
