Description
Trust Agents allows 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 #23, FIA_UAU.5.1

Ask the MDM administrator to display the "Minimum Password Complexity" setting in the "Android Password Restrictions" rule. 2. Verify the settings are "Alphanumeric". 3. Ask the MDM administrator to display the "Disable Keyguard Trust Agents" checkbox in the "Android Password Restrictions" rule. 4. Verify the checkbox is selected. On the Samsung Android 7 with Knox device, do the following: 1. Open the device settings. 2. Select "Lock screen and security". 3. Select "Other security settings". 4. Select "Trust agents" 5. Verify all Trust Agents are disabled (grayed out) and cannot be enabled. If the MDM console "Disable Keyguard Trust Agents" checkbox is not selected, or if "Minimum Password Complexity" is not configured to "Alphanumeric", or on the Samsung Android 7 with Knox device, the user can enable the settings, this is a finding.
