Vulnerability discussion

The fingerprint reader can be used to authenticate the user in order to unlock the mobile device. At this time, no biometric reader has been approved for DoD use on mobile devices. 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 #45

Check content

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 Password Complexity" setting in the "Android Restrictions" rule. 2. Verify the settings are Alphanumeric. 3. Ask the MDM administrator to display the "Enable Smart Lock" setting in the "Android Restrictions" rule. 4. Verify the setting is disabled. On the Samsung Knox for Android device: 1. Open the device settings. 2. Select "Lock screen and security". 3. Select "Secure lock settings". 4. Verify "Smart Lock" is disabled (grayed out) and cannot be enabled. If "Smart Lock" is enabled or if the user is able to enable the settings on the device, this is a finding.

Fix text

Configure the MOS to not allow authentication mechanisms other than a Password Authentication Factor where the authentication provides user access to protected data Configure the mobile operating system to disable Smart Lock. On the MDM Administration Console, disable "Enable Smart Lock" setting in the "Android Restrictions" rule.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
