Description
Audit logs and alerts enable monitoring of security-relevant events and subsequent forensics when breaches occur. They help identify when the security posture of the device is not as expected, including when critical or security-relevant applications have not fully installed on mobile devices under management of the MDM platform. This enables the MDM administrator to take an appropriate remedial action. SFR ID: FAU_ALT_EXT.2.1

This requirement is not applicable if the AO has not designated any required applications be installed on site managed mobile devices.

Verify a compliance email alert has been set up on the UEM server to alert if required apps are not installed on managed mobile devices.

- Have the UEM administrator determine the polling interval set up on the console (how often UEM checks compliance for managed mobile devices). (Note: For this review, have the administrator temporarily change the polling interval to 30 minutes or less.)
- Have the site UEM administrator identify one app required on site managed mobile devices.
- Using a site managed mobile device, remove the required app from the mobile device.
- After the polling interval time has occurred, review the BlackBerry UEM server configuration to determine whether an alert was generated for non-compliance of the test mobile device.
***On the UEM console, click on the Managed Devices tab
***Verify a warning message and link is displayed
***Clink on the link and verify the test managed device and removed app are listed as out of compliance

If a compliance email alert has not been set up on the UEM server to alert if required apps are not installed on managed mobile devices, this is a finding.
