Vulnerability discussion

SmartLock 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 #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. Select "Smart Lock". 5. Verify all items are disabled (grayed out) and cannot be enabled. If items are enabled or if the user can enable the settings on the device, this is a finding.

Fix text

Configure the mobile operating system 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 the "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.
