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.
Verify the assigned home directory of all local interactive users has a mode of "0750" or less permissive with the following command:
$ ls -ld $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd)
drwx------. 2 simon simon 83 Nov 30 12:30 /home/simon
drwx------. 2 test test 83 Jan 19 14:18 /home/test
drwx------. 2 test testdupe 62 Jan 15 11:44 /home/testdupe
If home directories referenced in "/etc/passwd" do not have a mode of "0750" or less permissive, this is a finding.
