Description
Many mobile devices display notifications on the lock screen so users can obtain relevant information in a timely manner without having to frequently unlock the phone. However, in many cases, these notifications can contain sensitive information. When they are available on the lock screen, an adversary can view them merely by being in close physical proximity to the device. Configuring the mobile operating system not to send notifications to the lock screen mitigates this risk. SFR ID: FMT_SMF.1.1 #18
