Description
Authentication mechanisms other than a Password Authentication Factor often provide convenience to users, but many of these mechanisms have known vulnerabilities. Configuring a minimum password complexity mitigates the risk associated with a weak authentication factor. SFR ID: FMT_SMF_EXT.1.1 #45

Check Text ( C-62227r1_chk )
This validation procedure is performed on both the MDM Administration Console and the Samsung Knox for Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Minimum Complexity" setting in the "Android Knox Container -> Container Password Restrictions" rule. 2. Verify the value of the setting is Alphanumeric. On the Samsung Knox for Android device: 1. Open the Knox Container. 2. Select "Knox Settings". 3. Select "Unlock method". 4. Enter current password. 5. Verify PIN and Pattern are grayed out and cannot be selected. If the configured value of the "Min Complexity" setting is not Alphanumeric, or if the user is able to select PIN or Pattern, this is a finding. Note: This configuration setting will allow users to implement fingerprint unlock for the container, which is approved for use. However, this approval does not extend to fingerprint unlock for the Samsung device or any other DoD mobile device.
