Fix Recommendation

Configure all public directories to be owned by root or a system account to prevent unauthorized and unintended information transferred via shared system resources.

Set the owner of all public directories as root or a system account using the command, replace "[Public Directory]" with any directory path not owned by root or a system account:

$ sudo chown root [Public Directory]

Check Contents

Check to see that all public directories are owned by root or a system account with the following command:

$ sudo find / -type d -perm -0002 -exec ls -lLd {} \;

drwxrwxrwxt 7 root root 4096 Jul 26 11:19 /tmp

If any of the returned directories are not owned by root or a system account, this is a finding.
