Check content

This validation procedure is performed on both the MDM Administration Console and the Samsung Knox for Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow Export Calendar to Personal Mode" setting in the "Android Knox Container -> Container Restrictions" rule. 2. Verify the setting is disabled. On the Samsung Knox for Android device: 1. Open the Knox container. 2. Select "Knox Settings". 3. Select "Share data". 4. Verify "Export to Personal Mode - Calendar" is disabled and attempt to enable this setting. If the "Allow Export Calendar to Personal Mode" configuration in the MDM console is enabled, or if the user is able to successfully enable this setting, this is a finding.

Fix text

Configure the mobile operating system to disable sharing of calendar information outside the container. On the MDM Administration Console, disable the "Allow Export Calendar to Personal Mode" setting in the "Android Knox Container -> Container Restrictions" rule.
