The screen-lock timeout helps protect the device from unauthorized access. Devices without a screen-lock timeout provide an opportunity for adversaries who gain physical access to the mobile device through loss, theft, etc. Such devices are much more likely to be in an unlocked state when acquired by an adversary, thus granting immediate access to the data on the mobile device, and possibly access to DoD networks.

Review Honeywell Android device configuration settings to determine if the mobile device is enforcing a screen-lock policy that will lock the display after a period of inactivity.

This validation procedure is performed on both the MDM Administration console and the Android Pie device. 

On the MDM console:
1. Open password requirements.
2. Open device password section.
3. Ensure "Device Lock Timeout" is set to any number desired. Units are in minutes.

On the Honeywell Android Pie device:
1. Open settings >> Security & location.
2. Click the "gear" icon next to "Screen lock".
3. Ensure "Automatically lock" is set at a required time.

If the MDM console device policy is not set to enable a screen-lock policy that will lock the display after a period of inactivity or on the Honeywell Android Pie device, the device policy is not set to enable a screen-lock policy that will lock the display after a period of inactivity, this is a finding.
