Vulnerability discussion

Requiring all authorized applications to be in an application whitelist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the whitelist. Failure to configure an application whitelist properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DoD data accessible by these applications.The application whitelist, in addition to controlling the installation of applications on the MD, must control user access/execution of all core applications (included in the operating system (OS) by the OS vendor) and pre-installed applications (provided by the MD vendor and wireless carrier), or the MD must provide an alternate method of restricting user access/execution to core and pre-installed applications.SFR ID: FMT_SMF_EXT.1.1 #10b

Check content

This validation procedure is performed on the MDM Administration Console. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the list of white-listed applications in the "Android Applications" rule. 2. Verify the list of white-listed applications has been approved by the Approving official (AO). Note: Refer to the Supplemental document for additional information. Note: This list can be empty if no applications have been approved. If any of the applications on white-listed applications on the MDM Administration Console have not been approved by the AO, this is a finding.

Fix text

Configure the MOS to use an application whitelist. On the MDM Administration Console, configure the list of white-listed applications in the "Android Applications" rule and ensure only AO-approved applications are on the list. Note: This list can be empty if no applications have been approved. Note: Refer to the Supplemental document for additional information.

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.
