Title

The macOS system must secure user's home folders. (Cat II impact)

Discussion

The system must be configured to prevent access to other user's home folders. The default behavior of macOS is to allow all valid users access to the top level of every other user's home folder while restricting access only to the Apple default folders within.

Check Content

Verify the macOS system is configured so that permissions are set correctly on user home directories with the following command: /usr/bin/find /System/Volumes/Data/Users -mindepth 1 -maxdepth 1 -type d ! \( -perm 700 -o -perm 711 \) | /usr/bin/grep -v "Shared" | /usr/bin/grep -v "Guest" | /usr/bin/wc -l | /usr/bin/xargs If the result is not "0", this is a finding.

Fix Text

Configure the macOS system to set the appropriate permissions for each user on the system with the following command: IFS=$'\n' for userDirs in $( /usr/bin/find /System/Volumes/Data/Users -mindepth 1 -maxdepth 1 -type d ! \( -perm 700 -o -perm 711 \) | /usr/bin/grep -v "Shared" | /usr/bin/grep -v "Guest" ); do /bin/chmod og-rwx "$userDirs" done unset IFS
