Fix Recommendation

Change the group owner of a local interactive user's home directory to the group found in "/etc/passwd" using the following command:

Note: The example will be for the user "disauser", who has a home directory of "/home/disauser", and has a primary group of users.

$ sudo chgrp users /home/disauser

Check Contents

Verify OL 9 configures assigned home directories of all local interactive users to be group-owned by that user's primary GID with the following command:

Note: This may miss local 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. The returned directory "/home/disauser" is used as an example.

$ sudo ls -ld $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd)
drwxr-x--- 2 disauser admin 4096 Jun 5 12:41 disauser

Check the user's primary group with the following command:

$ sudo grep $(grep disauser /etc/passwd | awk -F: '{print $4}') /etc/group
admin:x:250:disauser,doduser,nsauser

If the user home directory referenced in "/etc/passwd" is not group-owned by that user's primary GID, this is a finding.
