Vulnerability discussion

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 #47

Review Samsung Android 8 with Knox configuration settings to determine if the mobile device is enforcing minimum CONTAINER password complexity. This validation procedure is performed on both the MDM Administration Console and the Samsung Android 8 with Knox device. On the MDM console, do the following: 1. Ask the MDM Administrator to display the "Minimum Password Complexity" setting in the "Android Knox CONTAINER >> CONTAINER Password Restrictions" rule. 2. Verify the value of the setting is "Alphanumeric". On the Samsung Android 8 with Knox device, do the following: 1. Open the Knox CONTAINER. 2. Select "Workspace settings". 3. Select "Lock type". 4. Enter current password. 5. Verify "PIN" and "Pattern" are grayed out and cannot be selected. If the MDM console "Minimum Password Complexity" is not set to "Alphanumeric" or on the Samsung Android 8 with Knox device, the user is able to select "PIN" or "Pattern" from the "Lock Type" setting, 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.
