macOS 15 - Sequoia
The macOS system must secure users' home folders
Description
The system must be configured to prevent access to other users' 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.Satisfies: SRG-OS-000480-GPOS-00230, SRG-OS-000480-GPOS-00228
Check
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/xargsIf the result is not "0", this is a finding.
Fix
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"doneunset IFS
