Title

The macOS system must disable iCloud Private Relay. (Cat II impact)

Discussion

Enterprise networks may be required to audit all network traffic by policy; therefore, iCloud Private Relay must be disabled. Network administrators can also prevent the use of this feature by blocking DNS resolution of mask.icloud.com and mask-h2.icloud.com.

Check Content

Verify the macOS system is configured to disable the iCloud Private Relay with the following command: /usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowCloudPrivateRelay').js EOS If the result is not "false", this is a finding.
