There are two methods that can used to meet this requirement. The site should choose which method to use. Method #1: Disable all function of the device USB port This is a Good security policy set check. Recommend all checks related to Good security policy set rules be reviewed using the following procedure. 1. Make a list of all Good security policy sets assigned to smartphone user accounts on the Good server using the following procedure: -Have the SA identify any non STIG-compliant policy sets and STIG-compliant policy sets on the server. --Log into the Good Mobile Control console. --Click on the Policies tab. --View all policy set on the server. -Note: STIG-compliant policy sets should be identified as such in the policy title, for example, STIG_Android_Policy_Set. It is recommended all non STIG-compliant policy sets be deleted. 2. Select each policy set users are assigned to, and in turn, verify the required settings are in the policy set. Note: If there is a finding, note the name of the non STIG-compliant policy set in the Findings Details section in VMS/Component Provided Tracking Database. --------------------- -Launch the Good Mobile Control Web console and click on the Policies tab. -Select the policy set for the Android devices and click on Android Configuration on the left side. -Click the Restrictions tab. -Verify under Hardware Functionality “Allow use of USB port” is not checked. Method #2: Enable the device USB port but disable the mass storage function of the USB port Procedure: If the USAB port is enabled (see method #1 procedure, “Allow use of USB port” is checked), then “Mass Storage” must be set to “Disable.” First, verify the Dell Setup.apk file has been installed on the mobile OS device. -Have the system administrator show that the Dell Setup.apk is in the list of installed applications on the device (Settings>Applications>Manage applications>All). If the file is not listed, confirm with the SA that the file was installed on the device during setup, run, and then removed. (Note, a future release of the Good server will include the “Mass Storage” configuration setting in the Android security policy set and setup.apk will no longer be required.) Mark as a finding if either method #1 or Method #2 has not been implemented.
