Note: The advisory notice and consent warning message is not required if the general purpose OS or network device displays an advisory notice and consent warning message when the administrator logs on to the general purpose OS or network device prior to accessing The BlackBerry UEM 12.7 server or MDM server platform. Before granting access to the system, The BlackBerry UEM 12.7 server/server platform is required to display the DoD-approved system use notification message or banner that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. This ensures the legal requirements for auditing and monitoring are met. The approved DoD text must be used as specified in the KS referenced in DoDI 8500.01. The non-bracketed text below must be used without any changes as the warning banner. [A. Use this banner for desktops, laptops, and other devices accommodating banners of 1300 characters. The banner shall be implemented as a click-through banner at logon (to the extent permitted by the operating system), meaning it prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating “OK.”] You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details. SFR ID: FMT_SMF.1.1(2) d

Having several administrative roles for MDM server 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. Responsible for the maintenance of applications in the MAS. (Called "Security Administrator" in UEM) - Security configuration administrator: Responsible for security configuration of the server, defining device user groups, setup and maintenance of device user group administrator accounts, and defining privileges of device user group administrators. (UEM Enterprise Administrator, Help Desk Administrator or custom roles can be used for this role) - Device user group administrator: Responsible for maintenance of mobile device accounts, including setup, change of account configurations, and account deletion. Responsible for defining which apps user groups or individual users have access to in the MAS. Can only perform administrative functions assigned by the security configuration administrator. (UEM Enterprise Administrator, Help Desk Administrator or custom roles can be used for this role) - Auditor: Responsible for reviewing and maintaining server and mobile device audit logs. (These is no predefined role in UEM) SFR ID: FMT_SMR.1.1(1)
Checks: C-78009r1_chk

Review the BlackBerry UEM 12.7 server configuration settings, and verify the server is configured with the Administrator roles: a. UEM Security Administrator b. Auditor c. One or more Site Custom Administrator or UEM predefined enterprise/help desk roles Note: The exact name of the role is not important. Each role should include functions close to the role descriptions listed in the VulDiscussion. Note: The intent of the requirement is that there be separate people performing each administrator role; few users are assigned to the UEM Security Administrator role; the auditor role is limited to only authorized permissions; and day-to-day management of user accounts, group accounts, and profiles are performed from site specific custom administrator roles or UEM predefined enterprise/help desk roles instead of the UEM Security Administrator. On the BlackBerry UEM 12.7, do the following: 1. Log in to the BlackBerry UEM 12.7 console and select the "Settings” tab at the top of the screen. 2. Expand the General settings tab on the left pane. 3. Expand the Administrators tab on the left pane. 4. Select the Roles tab on the left pane. 5. Verify there is at least one user assigned to each of the following roles: a. UEM Security Administrator b. Auditor c. One or more Site Custom Administrator or UEM predefined enterprise/help desk roles Verify the auditor role function is limited to only reviewing and maintaining server and mobile device audit logs as follows: 1. Log in to the BlackBerry UEM 12.7 console and select the "Settings” tab at the top of the screen. 2. Expand the Administrators tab on the left pane. 3. Select the Roles tab on the left pane. 4. Click on the Auditor role. 5. Verify the role only has the following permissions assigned: - View audit information - Delete BlackBerry Dynamics audit log files - View and export BlackBerry Dynamics audit log files - View audit settings - Edit audit settings and purge data - Edit logging settings Talk to the UEM Security Administrator and verify custom administrator roles / UEM predefined enterprise/help desk roles are used for day-to-day management of user accounts, group accounts, and profiles. If at least one user is not associated with the UEM Security Administrator, Auditor, and one or more site custom administrator roles/UEM predefined enterprise/help desk roles, this is a finding. If the auditor role has more permissions than authorized, this is a finding. If day-to-day management of user accounts, group accounts, and profiles is primarily performed by UEM Security Administrators instead of one or more site custom administrator roles/UEM predefined enterprise/help desk roles, this is a finding.

A comprehensive account management process that includes automation helps to ensure the accounts designated as requiring attention are consistently and promptly addressed. If an attacker compromises an account, the entire MDM server infrastructure is at risk. Providing automated support functions for the management of accounts will ensure only active accounts will be granted access with the proper authorization levels. These objectives are best achieved by configuring the BlackBerry UEM 12.7 server to leverage an enterprise authentication mechanism (e.g., Microsoft Active Directory Kerberos). SFR ID: FIA
Checks: C-78011r1_chk

Review the BlackBerry UEM 12.7 server configuration settings, and verify the server is configured to leverage the MDM Platform user accounts and groups for BlackBerry UEM 12.7 server user identification and authentication. On the BlackBerry UEM 12.7, do the following: 1. Navigate to the BlackBerry UEM 12.7 console. 2. Verify the BlackBerry UEM 12.7 does not prompt for additional authentication before opening the UEM console. If the BlackBerry UEM 12.7 server prompts for additional authentication before opening the UEM console, this is a finding.

A session time-out lock is a temporary action taken when a user (a MDM system administrator) stops work and moves away from the immediate physical vicinity of the information system but does not log out because of the temporary nature of the absence. Rather than relying on the user to manually lock their application session prior to vacating the vicinity, applications need to be able to identify when a user's application session has idled and take action to initiate the session lock. The session lock is implemented at the point where session activity can be determined and/or controlled. This is typically at the operating system level and results in a system lock but may be at the application level where the application interface window is secured instead. SFR ID: FMT_SMF.1.1(2) b
Checks: C-78015r1_chk

Review the BlackBerry UEM server configuration to determine whether the system is locked after "15" minutes. On the BlackBerry UEM, do the following: 1. Log in to the BlackBerry UEM host server and navigate to “C:\BlackBerry\BlackBerry Configuration Tool 1.4.0\BESConfigTool.exe" and launch the BlackBerry UEM Configuration Tool. Note: If the BlackBerry UEM Configuration Tool was not installed in the default directory, you will need to locate the directory with the executable file to launch the application. 2. Select the "BlackBerry UEM console timeout interval" radio button. 3. Click "Next". 4. Click "Validate" to verify the Database information. 5. Verify the "Session timeout (seconds)" field is populated with "900" or less. 6. Click "Quit" to exit the application. Alternately, clock the time on a server to validate that it is correctly enforcing the time period. If the "Session timeout (seconds)" field is not populated with "900" or less, this is a finding.

Most information systems are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Unneeded services and processes provide additional threat vectors and avenues of attack to the information system. The BlackBerry UEM server is a critical component of the mobility architecture and must be configured to enable only those ports, protocols, and services (PPS) necessary to support functionality. All others must be expressly disabled or removed. A DoD-approved firewall implements the required network restrictions. A host-based firewall is appropriate where the BlackBerry UEM server runs on a standalone platform. Network firewalls or other architectures may be preferred where the BlackBerry UEM server runs in a cloud or virtualized solution. SFR ID: FMT_SMF.1.1(2) b
Checks: C-78017r1_chk

Review the BlackBerry UEM server platform configuration to determine whether a DoD-approved firewall is installed or if the platform operating system provides a firewall service that can restrict both inbound and outbound traffic by TCP/UDP port and IP address. If there is not a host-based firewall present on the BlackBerry UEM server platform, this is a finding.

Fix: F-85187r1_fix

Install a DoD-approved firewall.
