Change the group owner of a SLEM 5 local interactive user's home directory to the group found in "/etc/passwd". To change the group owner of a local interactive user's home directory, use the following command:
Note: The example will be for the user "dosuser", who has a home directory of "/home/dosuser", and has a primary group of users.
> sudo chgrp users /home/dosuser
Verify the assigned home directory of all SLEM 5 local interactive users is 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/dosuser" is used as an example.
> awk -F: '($3>=1000)&&($7 !~ /nologin/){print $4, $6}' /etc/passwd)
250:/home/dosuser
Check the user's primary group with the following command:
> grep users /etc/group
users:x:250:dosuser,dosuser,nsauser
If the user home directory referenced in "/etc/passwd" is not group-owned by that user's primary GID, this is a finding.
