The MDM must disable copying data from inside the security container to a non-secure data area on the mobile device in the security policy implemented on managed mobile devices.

Description
A security container is required on any device that uses a mobile OS that with an encryption module that is not FIPS 140-2 validated. An approved security container application uses FIPS 140-2 validated cryptographic module with AES encryption to protect data. If this requirement is not met, sensitive data could be saved in the non-FIPS 140-2 validated area of memory on the mobile device, which would violate DoD policy and may expose sensitive DoD data.

If the MDM client provides the mobile device security container, use the following procedure for verifying requirement is met: 1. Make a list of all iOS security policies listed on the MDM server that have been assigned to iOS devices and review each policy using the following procedure: -Have the SA identify STIG compliant and non compliant policies on the server. --Log into the MDM server console. --Click on the Policies tab. --View all iOS security policies on the server. -Note: STIG-compliant policies should be identified as such in the policy title. An example is STIG_iOS_Policy. It is recommended that all non-STIG policies be deleted. 2. Select each security policy iOS devices are assigned to, and in turn, verify the required settings are in the policy. -Note: If there is a finding, note the name of the non STIG-compliant policy in the Findings Details section in VMS/Component Provided Tracking Database. -Launch the MDM console and click on the Policies tab. -Select an iOS security policy to review. -The exact procedure used to verify the required setting will vary by MDM product. For the Good MDM server: -Verify copying out of secure sandbox has been disabled. Have the administrator log in to the Good Mobile Control console and choose the iOS policy. In the Messaging section ensure that “Do not allow data to be copied from the Good application” is checked. Mark as a finding if copying data from inside the security container to a non-secure data area on the mobile device is not disabled in the security policy.

If the MDM client provides the mobile device security container, use the following procedure for verifying requirement is met:

1. Make a list of all iOS security policies listed on the MDM server that have been assigned to iOS devices and review each policy using the following procedure:
-Have the SA identify STIG compliant and non compliant policies on the server.
--Log into the MDM server console.
--Click on the Policies tab.
--View all iOS security policies on the server.
-Note: STIG-compliant policies should be identified as such in the policy title. An example is STIG_iOS_Policy. It is recommended that all non-STIG policies be deleted.

2. Select each security policy iOS devices are assigned to, and in turn, verify the required settings are in the policy.
-Note: If there is a finding, note the name of the non STIG-compliant policy in the Findings Details section in VMS/Component Provided Tracking Database.
-Launch the MDM console and click on the Policies tab.
-Select an iOS security policy to review.
-The exact procedure used to verify the required setting will vary by MDM product.

For the Good MDM server:
-Verify copying out of secure sandbox has been disabled. Have the administrator log in to the Good Mobile Control console and choose the iOS policy. In the Messaging section ensure that “Do not allow data to be copied from the Good application” is checked.

Mark as a finding if copying data from inside the security container to a non-secure data area on the mobile device is not disabled in the security policy.

Disable copying files from inside the security container to a non-secure data area on the mobile device on the MDM server security policy implemented on managed mobile devices.
