Title

BlackBerry OS 10.3 must be configured to prevent non-approved updates of system software. (Cat II impact)

Discussion

FOTA allows the user to download and install firmware updates over-the-air. These updates can include OS upgrades, security patches, bug fixes, new features and applications. Since the updates are controlled by the carriers, DoD will not have an opportunity to review and update policies prior to update availability to end users. Disabling FOTA will mitigate the risk of allowing users access to applications that could compromise DoD sensitive data. After reviewing the update and adjusting any necessary policies (i.e., disabling applications determined to pose risk), the administrator can re-enable FOTA. SFR ID: FMT_SMF_EXT.1.1 #45

Review BlackBerry OS 10.3 configuration settings to determine if the BlackBerry is configured to prevent non-approved updates of system software. This procedure is performed only on the BES console. Note: If an organization has multiple configuration profiles, then the Implementation procedure must be performed on the relevant configuration profiles applicable to the scope of the review. On the BES 12, do the following: 1. Log into the BES 12 console and select the "POLICIES AND PROFILES” tab at the top of the screen. 2. Expand the “IT policies” tab on the left pane. 3. Select and open each IT policy assigned to users in turn. 4. After opening the policy, select the “Settings” and “BlackBerry” tabs. 5. Scroll down to the “Device functionality” group of IT policy rules. 6. Verify "Allow wireless software updates" is set to "allow". 7. Verify a Device SR requirement profile is assigned to every user: -Click on "Users and Devices" tab at the top of the screen. -Select at least 5 random users in-turn -Select the user -Verify a Device SR requirement profile is listed under IT policy and profile Note: Step 7 above will, by default, verify "Maximum software release version" has a value. If the BES IT policy rule "Allow wireless software updates" is not selected and a Device SR requirement profile has not been assigned to all users, this is a finding. Note: Procedures above are for BES 12 only. BES 10 procedures may be slightly different.
