Australian Information Security Manual ISM-2012: Screen lock configuration

Systems are configured with a screen lock that: - activates after a maximum of 15 minutes of user inactivity, or when manually activated by users - conceals all content on the screen - ensures that the screen does not enter a power saving state before the screen lock is activated - requires users to re-authenticate using all authentication factors to unlock the system - denies users the ability to disable the screen locking mechanism.
