AIOS-13-000300 - Apple iOS/iPadOS must be configured to lock the display after 15 minutes (or less) of inactivity.


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.

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


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.
