Title

The BlackBerry Enterprise Mobility Server (BEMS) must be configured to have at least one user in the following Administrator roles: Server primary administrator, auditor. (Cat II impact)

Discussion

Having several administrative roles for the BEMS supports separation of duties. This allows administrator-level privileges to be granted granularly, such as giving application management privileges to one group and security policy privileges to another group. This helps prevent administrators from intentionally or inadvertently altering other settings and configurations they may not understand or approve of, which can weaken overall security and increase the risk of compromise. - Server primary administrator: Responsible for server installation, initial configuration, and maintenance functions. Responsible for the setup and maintenance of security configuration administrator and auditor accounts. - Auditor: Responsible for reviewing and maintaining server and mobile device audit logs.

Check Content

Verify BEMS has been configured with the following administrator groups/roles, each group/role has required permissions, and at least one user has been assigned to each Administrator group/role: Server primary administrator, auditor. Procedure for Server Primary Administrator: 1. In the BEMS Dashboard, under "BEMS System Settings", click "BEMS Configuration". 2. Click "Dashboard Administrators". 3. Confirm the Administrator role for the primary server administrator has been assigned the dashboard role of Admin. 4. Verify in Active Directory (AD) at least one member has been assigned to the BEMS administrator group. (Note: Actual group name may be different.) Procedure for Auditor: 1. Verify in AD an auditor group has been set up with at least one member. 2. Browse to the log repository. 3. Right-click on the folder. 4. Select "Properties". 5. Select the "Security" tab. 6. Confirm the auditor security group is listed. If required administrator roles have not been set up on BEMS and at least one user has not been assigned to each role, this is a finding.
