Description
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.
ℹ️ Check
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.
✔️ Fix
Configure the macOS system to disable the iCloud Private Relay by installing the "com.apple.applicationaccess" configuration profile.
