Check Text (C-221729r991589_chk)

Verify the assigned home directory of all local interactive users has a mode of "0750" or less permissive. 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 $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd) -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.

Fix Text (F-23433r419260_fix)

Change the mode of interactive user's home directories to "0750". To change the mode of a local interactive user's home directory, use the following command: Note: The example will be for the user "smithj". # chmod 0750 /home/smithj
