Vulnerability discussion

Developer modes expose features of the MOS that are not available during standard operation. An adversary may leverage vulnerability inherent in a developer mode to compromise the confidentiality, integrity, and availability of DoD-sensitive information. Disabling developer modes mitigates this risk.SFR ID: FMT_SMF_EXT.1.1 #24

Check content

This check procedure is performed on both the MDM Administration Console and the Samsung Knox device. Check that the appropriate setting is configured on the MDM Administration Console. 1. Ask the MDM administrator to display the "Disable Developer Mode" settings in the "Android Restrictions" rule. 2. Verify that the "Disable Developer Mode" setting is enabled. Note: Disabling Developer Mode will also disable USB Debugging and Mock locations. On the Samsung Knox for Android Device: 1. Open the device settings. 2. Select "Developer options". (**) 3. Attempt to enable "Developer options". If the "Disable Developer Mode" setting in the MDM console is disabled, or if the user is able to enable "Developer options" on the device, this is a finding. Note: The "Developer Modes" configuration setting may not be available in older MDM consoles. Disabling USB Debugging and Mock Locations also disables developer modes on the mobile device. (**) "Developer options" is initially hidden to users. To unhide this menu item, 1. Open the device settings. 2. Select "About phone". 3. Rapidly tap on "Build number" multiple times until device displays the developer options menu item.
