Title

Email Administrator Groups must ensure least privilege. (Cat II impact)

Discussion

When an oversight responsibility is assigned to the same person performing the actions being overseen, the function of oversight is compromised. When the responsibility to manage or control one application or activity is assigned to one party yet another party is also assigned the privilege to the same actions, then neither party can logically be held responsible for those action. By separating responsibility and permissions by role, accountability can be as granular as needed. Role Based Access Control (RBAC) strategies for email administration include server role administration, permissions within server roles, and task based assignments. Further granularity is possible, and often makes sense to do, enabling each role to operate using the least possible permissions to perform the role.

Check Content

Review EDSP documentation that describes division of duties by role in the email domain administration assignments. If Email Administrator tasks are assigned to a defined role in the organization, and the role is operating at least privilege for the tasks, this is not a finding.

Fix Text

Assign administrators to roles with appropriate permissions for Email Administrators. Configure each role so it is commensurate with least possible permission to perform the associated tasks.
