A session time-out lock is a temporary action taken when a user (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 leaving the vicinity, applications must 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) c.8

Checks: C-26051r539022_chk

Review the BlackBerry UEM server configuration to determine whether the system is locked after 15 minutes. Have the system administrator log into the console. Verify the session locks after 15 minutes of inactivity. If the "Session timeout" is not set correctly, this is a finding.

Fix: F-26039r539023_fix

On the BlackBerry UEM, do the following to set the session timeout: 1. Log in to the BlackBerry UEM console. 2. Go to the menu bar on the left. 3. Go to Settings >> General Settings >> Console. 4. Under "Session settings", enter "15". 5. Select "Save".

Having several administrative roles for the BlackBerry UEM 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. - 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. - 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. - Auditor: Responsible for reviewing and maintaining server and mobile device audit logs. SFR ID: FMT_SMR.1.1(1)

Checks: C-26054r539031_chk

Review the BlackBerry UEM server configuration settings. 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 separate people perform 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, do the following: 1. Log in to the BlackBerry UEM console. 2. Select the "Settings" tab at the top of the screen. 3. Expand the "General" settings tab on the left pane. 4. Expand the "Administrators" tab on the left pane. 5. Select the "Roles" tab on the left pane. 6. Verify at least one user is 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 console. 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 the "Auditor" role. 5. Verify the role only has the following permissions assigned: - View audit information; - View audit settings; - Edit audit settings and purge data; and - Edit logging settings. Talk to the "UEM Security Administrator". 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.

Fix: F-26042r539032_fix

On the BlackBerry UEM, do the following: Using the procedures below: - Assign at least one user to the UEM Security Administrator role. Few administrators should be assigned to this role. Note: UEM automatically restricts the following functions to only the Security Administrator: Full permissions to manage the BlackBerry Enterprise Solution. Create and edit roles. - Define an "Auditor" role (see the VulDiscussion for role functions). Assign at least one user (UEM administrator) to the role. The role should include only the following UEM permissions: ** 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. - Define site custom administrator roles or UEM predefined enterprise/help desk roles as needed to administer device policies and user accounts (for example, see the Security Configuration Administrator and Device User Group Administrator in the VulDiscussion). Assign users to the roles as required. These roles should be used for day-to-day management of user accounts, group accounts, and profiles. To set up specific roles, do the following: 1. Go to Settings >> Administrators >> Roles. 2. Select "roles" in the left pane. 3. Select "add a role" on the top right. 4. Assign appropriate name and functions to the role. 5. Click "Save".

Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. Audit records can be generated from various components within the application (e.g., process, module). Certain specific application functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records. DoD has defined the list of events for which the application will provide an audit record generation capability as the following: (i) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels); (ii) Access actions, such as successful and unsuccessful logon attempts, privileged activities or other system level access, starting and ending time for user access to the system, concurrent logons from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; and (iii) All account creation, modification, disabling, and termination actions. DoD Required auditable events (from the MDM Protection Profile): - Change in enrollment status - Failure to apply policies to a mobile device - Start up and shut down of the MDM System - All administrative actions - Commands issued to the MDM Agent, none] - Specifically defined auditable events listed in Table 2 of the MDM Protection Profile SFR ID: FAU_GEN.1.1(1), FMT_SMF.1.1(2)c.8

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 / CM-7 b Satisfies: SRG-APP-000142

Checks: C-26059r539046_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-26047r539047_fix

Install a DoD-approved firewall.

b

The firewall protecting the BlackBerry UEM server platform must be configured to restrict all network traffic to and from all addresses with the exception of ports, protocols, and IP address ranges required to support BlackBerry UEM server and platform functions.

Some of the functions and services, provided by default, may not be necessary to support essential organizational operations. Since 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 firewall installed on the BlackBerry UEM server provides a protection mechanism to ensure unwanted service requests do not reach the BlackBerry UEM server and outbound traffic is limited to only BlackBerry UEM server functionality.

Ask the BlackBerry UEM administrator for a list of ports, protocols, and IP address ranges necessary to support BlackBerry UEM server and platform functionality. A list can usually be found in the STIG Supplemental document or BlackBerry UEM product documentation. Compare the list against the configuration of the firewall and identify discrepancies. If the host-based firewall is not configured to support only those ports, protocols, and IP address ranges necessary for operation, this is a finding.

Fix: F-26048r539050_fix

Configure the firewall on the BlackBerry UEM server to only permit ports, protocols, and IP address ranges necessary for operation.

b

The firewall protecting the BlackBerry UEM server platform must be configured so that only DoD-approved ports, protocols, and services are enabled. (See the DoD Ports, Protocols, Services Management [PPSM] Category Assurance Levels [CAL] list for DoD-approved ports, protocols, and services).

All ports, protocols, and services used on DoD networks must be approved and registered via the DoD PPSM process. This is to ensure that a risk assessment has been completed before a new port, protocol, or service is configured on a DoD network and has been approved by proper DoD authorities. Otherwise, the new port, protocol, or service could cause a vulnerability to the DoD network, which could be exploited by an adversary. SFR ID: FMT_SMF.1.1(2) b / CM-7 b Satisfies: SRG-APP-000142

Checks: C-26061r539052_chk

Ask the BlackBerry UEM administrator for a list of ports, protocols, and services that have been configured on the host-based firewall of the BlackBerry UEM server or generate the list by inspecting the firewall. Verify all allowed ports, protocols, and services are included on the DoD PPSM CAL list. If any allowed ports, protocols, and services on the BlackBerry UEM host-based firewall are not included on the DoD PPSM CAL list, this is a finding.

Fix: F-26049r539053_fix

Turn off any ports, protocols, and services on the BlackBerry UEM host-based firewall that are not on the DoD PPSM CAL list.

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 BlackBerry UEM 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 server to leverage an enterprise authentication mechanism (e.g., Microsoft Active Directory Kerberos).

On the BlackBerry UEM, do the following: Configure constrained delegation for the Microsoft Active Directory account to support single sign-on: 1. Log in to the BlackBerry UEM 12.12 host server and use the Windows Server ADSI Edit tool to add the following SPNs for BES12 to the Microsoft Active Directory account: - HTTP/<host_FQDN_or_pool_name> (for example, HTTP/domain123.example.com) - BASPLUGIN111/<host_FQDN_or_pool_name> (for example, BASPLUGIN111/domain123.example.com) Note: - If high availability is configured for the management consoles in a UEM domain, specify the pool name. Otherwise, specify the FQDN of the computer that hosts the management console. - Verify that no other accounts in the Microsoft Active Directory forest have the same SPNs. 2. Open "Microsoft Active Directory Users and Computers". 3. In the Microsoft Active Directory account properties, on the "Delegation" tab, select the following options: - Trust this user for delegation to specified services only. - Use Kerberos only. 4. Add the SPNs from Step 1 to the list of services. Configure single sign-on for UEM: Note: - When configuring single sign-on for UEM, it is configured for the management console and UEM Self-Service. - If enabling single sign-on for multiple Microsoft Active Directory connections, verify there are no trust relationships between the Microsoft Active Directory forests. 1. Log in to the BlackBerry UEM 12.12 console. 2. Select the "Settings" tab on the left pane. 3. Click the "External integration" tab on the left pane. 4. Click "Company directory". 5. In the "Configured directory connections" section, click the name of a Microsoft Active Directory connection. 6.

Without protection of the transmitted information, confidentiality and integrity may be compromised since unprotected communications can be intercepted and either read or altered. This requirement applies only to those applications that are either distributed or can allow access to data non-locally. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When transmitting data, applications need to leverage transmission protection mechanisms, such as TLS, TLS VPNs, or IPsec. Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification. Protecting the confidentiality and integrity of organizational information can be accomplished by physical means (e.g., employing physical distribution systems) or by logical means (e.g., employing cryptographic techniques). If physical means of protection are employed, then logical means (cryptography) do not have to be employed, and vice versa.
