Content caching must be disabled.

Content caching is a macOS service that helps reduce internet data usage and speed up software
installation on Mac computers. It is not recommended for devices furnished to employees to act as a
caching server.

Check

Verify the macOS system is configured to disable content caching service with the
following command:

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowContentCaching').js
EOS

If the result is not "false", this is a finding.

Fix

Configure the macOS system to disable content caching service by
installing the "com.apple.applicationaccess" configuration profile.
