Description
If the mobile operating system were to display notifications or calendar information on the lock screen, an adversary may be able to gather sensitive data without needing to Unlock the device. This adversary may use this gathered intelligence to plan future attacks and possibly a physical attack. By disabling notifications on the lock screen, this prevents sensitive data from being displayed openly on the device’s lock screen. SFR ID: FMT_MOF.1.1(2) #12
