Check Text (C-257890r1044961_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.
$ stat -L -c '%a %n' $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd) 2>/dev/null
700 /home/bingwa
If home directories referenced in "/etc/passwd" do not have a mode of "0750" or less permissive, this is a finding.
