Check the home directory assignment for all non-privileged users on the system with the following command: Note: This may miss interactive users that have been assigned a privileged User Identifier (UID). Evidence of interactive use may be obtained from a number of log files containing system logon information. # ls -ld $(egrep ':[0-9]{4}' /etc/passwd \| cut -d: -f6) -rwxr-x--- 1 smithj users 18 Mar 5 17:06 /home/smithj If home directories referenced in "/etc/passwd" do not have a mode of "0750" or less permissive, this is a finding.
