Discussion

The system must be configured to not display sensitive information at the LoginWindow. The key AdminHostInfo, when configured, will allow the HostName, IP Address, and operating system version and build to be displayed.

Check Content

Verify the macOS system is configured to prevent AdminHostInfo from being available at LoginWindow with the following command:

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.loginwindow')\
.objectIsForcedForKey('AdminHostInfo')
EOS

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

Fix Text

Configure the macOS system to prevent AdminHostInfo from being available at LoginWindow by installing the "com.apple.loginwindow" configuration profile.
