Description
Application Restrictions must be enabled for user accounts and configured to only allow users to execute approved applications. Utilizing a whitelist such as Application Restrictions provides a configuration management method for allowing the execution of only authorized software. Using only authorized software decreases risk by limiting the number of potential vulnerabilities. The organization must identify authorized software programs and permit execution of authorized software. The process used to identify software programs that are authorized to execute on organizational information systems is commonly referred to as whitelisting.

Check Text ( C-68131r1_chk )
To check if there is a configuration policy defined for "Application Restrictions", run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType \| /usr/bin/grep "familyControlsEnabled = 1;" If nothing is returned, this is a finding. Built-in applications such as "FaceTime", "Game Center", "Mail", "Contacts", "Calendar", "Reminders", "Notes", and "Messages" should be evaluated against mission needs and should only appear in the list of allowed applications if specifically required.
