Check Text (C-248639r991589_chk)
Verify the assigned home directory of all local interactive users has a mode of "0750" or less permissive 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.
$ sudo ls -ld $(awk -F: '($3>=1000)&&($1!="nobody"){print $6}' /etc/passwd)
drwxr-x--- 2 smithj admin 4096 Jun 5 12:41 smithj
If home directories of interactive users referenced in "/etc/passwd" do not have a mode of "0750" or less permissive, this is a finding.
Fix Text (F-52027r779482_fix)
Change the mode of interactive users' home directories to "0750" using the following command.
Note: The example will be for the user "smithj".
$ sudo chmod 0750 /home/smithj
