Many software systems automatically send diagnostic data to the manufacturer or a third party. This data enables the developers to understand real world field behavior and improve the product based on that information. Unfortunately, it can also reveal information about what DoD users are doing with the systems and what causes them to fail. An adversary embedded within the software development team or elsewhere could use the information acquired to breach mobile operating system security. Disabling automatic transfer of such information mitigates this risk.
This validation procedure is performed on both the MDM Administration Console and the LG Android device. On the MDM console, do the following: 1. Ask the MDM administrator to display the "Allow Google crash report" setting in the MDM console. 2. Verify the Google crash report is disabled. 3. Verify the policy has been assigned to all groups. On the LG Android device: 1. Unlock the device. 2a. Navigate to Settings >> General. If "Developer mode" has already been disabled on the MDM console: Verify "Developer options" does not show on the screen. Also, navigate to Settings >> About phone >> Software info. Tap on "Build number" several times and verify that the device will not enable developer mode. 2b. Navigate to Settings >> General. If "Developer mode" has not been disabled on the MDM console: Enable USB debugging. Next go to Developer options >> Select Take bug report and choose "Report". Verify Google crash report cannot be used. If on the MDM console the "Allow Google crash report" setting is enabled or on the LG Android device the Google crash report is available, this is a finding.
Configure the mobile operating system to disable automatic transfer of diagnostic data to an external device other than an MDM service with which the device has enrolled. On the MDM Administration Console, disable the "Allow Google crash report" setting.
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.
