Fix Recommendation

Change the group owner of a SUSE operating system 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 "smithj", who has a home directory of "/home/smithj", and has a primary group of users.

> sudo chgrp users /home/smithj

Check Contents

Verify the assigned home directory of all SUSE operating system local interactive users is group-owned by that user's primary GID.

Check the home directory assignment for all non-privileged users on the system 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/smithj" is used as an example.

> awk -F: '($3>=1000)&&($7 !~ /nologin/){print $4, $6}' /etc/passwd)
250:/home/smithj

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

> grep users /etc/group
users:x:250:smithj,jonesj,jacksons

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