AIOS-14-000300 - The mobile operating system must be configured to enable a screen-lock policy that will lock the display after a period of inactivity.

Information

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.

SFR ID: FMT_SMF_EXT.1.1 #2a & #2b

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Install a configuration profile to lock the device display after 15 minutes (or less) of inactivity. This is done by setting 'Maximum Auto-Lock time' and 'Grace Period for device lock' so the sum of their values is between 1 and 15 minutes.
