WIR1315-01: The BES must be configured to disable the capability of the BES to proxy a user’s authentication to back-office application, web, and content servers. Users must authenticate directly to back-office servers using a USCYBERCOM CTO 07-15Rev1 authorized method.
Verify the site BES has been configured to require BlackBerry users to authenticate directly with enclave application and content servers. - On the BAS, go to Servers and components >> BlackBerry Solution topology >> BlackBerry Domain >> MDS Connection Service. -Click "Edit components". -Select the "HTTP" tab. -In the "Authentication support" enabled drop-down list, verify "No" has been selected. If the configuration setting is not correct, this is a finding. Exception: When a site Internet Proxy is set to require user authentication, the configuration setting above will cause a loss of Internet connectivity. In this case only, the "Support HTTP Authentication" setting should be set to TRUE, and then, when prompted, enter no value for the user authentication information (this will cause the BES to prompt for the user's authentication credentials whenever an Internet connection is requested). When a site uses authentication on the Internet proxy, the reviewer should verify the required setting for "Support HTTP Authentication" and then have users show on their BlackBerry they have to enter their Internet Proxy authentication credentials whenever they try to connect to the Internet.
Discussion
User authentication credentials should not be proxied by the BES, because the BES would then be saving DoD user authentication credentials in its database.
Fix
The BES must be configured to disable the capability of the BES to proxy a user’s authentication to back-office application, web, and content servers.

WIR1310-03: An Application Control Policy must be assigned to each application listed in any Application White List software configuration assigned to user accounts on the BES. Note: This check applies to BES 4.1.x only. On BES 5, an application control policy is automatically assigned when an application is selected for a software configuration.
Detailed Policy Requirements: An Application Control Policy must be set up on the BES for each application listed in an Application White List software configuration on the BES. For mandatory applications, the Application Control Policy should have the "Disposition" rule set to "Required". Check Procedures: Use the list of Application White List software configurations assigned to user accounts developed in Check WIR1310-01. Step 1: Determine the list of assigned Application Control Policies. For each Application White List software configuration assigned to a user, complete the following: - In the BlackBerry Manager, click "BlackBerry Domain" in the left pane. - Click "Software Configurations" tab. - In the Configuration Name list, double-click on one of the software configurations that was assigned to a BES User Group. - Expand the Application Software tree. - Determine if an Application Control Policy has been assigned to each application listed in the tree under the Application Software group. If an Application Control Policy has been assigned, note the name of the Application Control Policy. (Note: If an Application Control Policy has not been assigned to an application, this has the effect of denying the use of the application on site managed BlackBerry devices.) Step 2: Verify each Application Control Policy is configured as required. For each application listed under the Application Software group (for each software configuration), verify the Application Control Policy is compliant with the policy in Table C-4 of the BlackBerry STIG Overview. Use the following procedure to verify each Application Control Policy is configured correctly. - In the BlackBerry Manager, in the left pane, click "BlackBerry Domain". - On the "Software Configurations" tab, click "Manage Applications Policies". - For each Application Control Policy identified in Step 1, double click the policy to open it and verify it has been configured as required in Table C-4 of the BlackBerry STIG Overview. If any Application Control Policy is not configured as required, this is a finding. Identify the Application White List software configuration, Application Control Policy, and application in the VMS remarks. Remember to do the above steps for each Application White List software configuration. Findings comments in VMS should identify the Application White List software configuration and/or application not compliant.
Discussion
Applications must only have access to BlackBerry resources (e.g., microphone, address book, browser, email messages, etc.) they need for their function; otherwise, sensitive data could be exposed to unauthorized users or the BlackBerry system could be compromised.
Fix
Set up the required Applications Control Policies.

WIR1310-01: An Application White List software configuration must be assigned to all BES user accounts.
Check the BES to see if an Application White List software configuration has been assigned to each BES user account. Note: Section 3.2.5.2 of the BlackBerry STIG Overview has instructions for setting up an Application White List software configuration and assigning it to a user or a group account. For BES 5.0: -BAS >> BlackBerry solution management >> User >> Manage users -Select at least 20 user accounts from different offices or sites on the BES at random and complete the following: **Click on the user account name. **Click on the "Software configuration" tab. **Note the name of the software configuration assigned to the user (this will be the assigned "Application White List"). The name should be in a similar format to the following: "DISA Application White List 1". If any user account has not been assigned an Application White List software configuration, this is a finding. Note: The required configuration of the Application White List will be verified in checks WIR1310-02 and WIR1310-03.
Discussion
The primary BlackBerry malware control is to set up one or more Application White List software configurations on the BES. Every user and group account must be assigned at least one Application White List software configuration. In an Application White List, the use of all non-core applications is denied unless an application is expressly allowed.
Fix
An application White List software configuration must be assigned to all BES user accounts.

WIR1300-02: The BES host-based or appliance firewall must be configured as required.
Detailed Policy Requirements: The BES host-based or appliance firewall must be configured as required. The BES firewall is configured with the following rules: - Deny all except when explicitly authorized. - Internal traffic from the BES is limited to internal systems used to host the BlackBerry services (e.g., email and LDAP servers) and AO-approved back-office application and content servers. Communications with other services, clients, and/or servers are not authorized. - Internet traffic from the BES is limited to only those specified BlackBerry services (e.g., BlackBerry SRP server, OCSP, SSL/TLS, HTTP, and LDAP). All outbound connections are initiated by the BlackBerry system and/or service. - Firewall settings listed in Section 3.13 of the BlackBerry STIG Overview will be implemented, including blocking connections to web proxy servers and back-office application and content servers unless the server Internet Protocol (IP) address is on the firewall list of trust IP addresses and subnets. Note: At the minimum, the IP address of the site Internet proxy server must be listed so the BlackBerry Browser can connect to the Internet. Note: The HBSS firewall can be used to meet these requirements if one or more firewall rules have been set up on the firewall as described above. Check Procedures: Verify the firewall configuration meets approved architecture configuration requirements (or have the network reviewer do the review of the firewall). Use Table 3-5 in the BlackBerry STIG Overview when using the non-segmented architecture and Tables 3-6 and 3-7 when using the segmented architecture for required firewall rules. Verify the firewall is configured to block connections to internal servers unless the server IP address is included on the list of trusted networks. IP addresses of the enclave web proxy server and authorized back-office application and content servers that the BES connects to should be included on this list. If a list of trusted networks by IP address is not configured on the BES host-based firewall, this is a finding.

Remediation: If a certificate error occurs either the default self-signed certificate is still installed, the BlackBerry Enterprise Server has not been rebooted since the DoD-issued certificate has been installed, or the computer accessing the BAS does not have the DoD Root and Intermediate certificate authorities installed. The reviewer can select the "Continue to this website" option and follow the same procedure above. If the certificate is issued from an approved DoD PKI, ask the BlackBerry Administrator to run InstallRoot on the computer accessing the BAS. Otherwise, have the BlackBerry Administrator follow the procedures outlined in the STIG to request/install a certificate issued from a trusted DoD PKI.
Discussion
When a self-signed PKI certificate is used, a rogue BES can impersonate the DoD BES during SA connections to the BlackBerry Administration Service (BAS) or when a BlackBerry user uses BlackBerry Web Desktop Manager (BWDM) to connect to the BAS. In addition, DoDI 8520-02 requires PKI certificates come from a trusted DoD PKI.
Fix
Use a DoD-issued digital certificate on the BES to support BAS and BWDM authentication.
