LG Android 6.x must lock the display after 15 minutes (or less) of inactivity. (Cat II impact)

Discussion

The screen lock timeout must be set to a value that helps protect the device from unauthorized access. Having a too-long timeout would increase the window of 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. The maximum timeout period of 15 minutes has been selected to balance functionality and security; shorter timeout periods may be appropriate depending on the risks posed to the mobile device.

Check Content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. On the MDM console, do the following: 1. Ask the MDM administrator to display the "Maximum time to lock" setting in the password policy on the MDM console. 2. Verify the value of the setting is 15 minutes or less. On the LG Android device: 1. Unlock the device. 2. Navigate to the password entry screen: Settings >> General >> Security (or Fingerprints & security) >> Lock screen >> Lock timer. 3. Verify "Lock timer" is set to 15 minutes or less. If on the MDM console the "maximum time to lock" setting is not set to 15 minutes or less or if on the LG Android device the "Lock timer" is not set to 15 minutes or less, this is a finding.

Fix Text

Configure the mobile operating system to lock the device display after 15 minutes (or less) of inactivity. On the MDM Administration Console, set the "Maximum time to lock" value to 15 minutes (or less).
