Description
Trust agents allow a user to unlock a mobile device without entering a passcode when the mobile device is, for example, connected to a user-selected Bluetooth device or in a user-selected location. This technology would allow unauthorized users to have access to DoD sensitive data if compromised. By not permitting the use of non-password authentication mechanisms, users are forced to use passcodes that meet DoD passcode requirements. SFR ID: FMT_SMF_EXT.1.1 #22, FIA_UAU.5.1
